Picture of How to Build a Spangen Helm.
In the past People have asked me to put up an Instructable on how to build a helmet. So, for all you people, Here goes.

As the title says, this Instructable will deal with building a Spangen Helm. Since I wanted something a little more unique I went with a 5 panel instead of the standard 4, and used shaped bands rather than straight ones.

Although the finished helm has a bar grill I neglected to add a bar grill step to this Instructable. The reason for this is that it was my first bar grill and I had a surprisingly difficult time making it. Until I've gotten a little better at them I don't want to try and teach someone else how to make one.

Step 2: Step #1: Patterning Your Helmet.

Ok, So the first thing you need to do is Draw your helmet. Get a good idea of what you want the finished project to look like. If you cant put it down on paper you'll probably have a hard time making it with steel.

Got a few pictures of what you want? Good. Now it's time to start actually making patterns for this.

First thing you need to do is get the brow band. A good rule of thumb for this is to take the circumference of your head and add 3" for 1/2" of padding, or 5.5" for 3/4" of padding. Alternately you could add whatever padding you want to your head then measure the circumference.
In any case, The brow band for this helm is 1 1/4" wide and about 28" long.

Next come the bands. For a basic spangen helm you can just cut a pair of rectangle bands, 1-2" wide by however long you need and make them cross over the top, dividing your helmet bowl into 4 quarters. it's pretty simple. But, since I wanted something a little fancier here is how I did it.
I took the length of my brow band, divided it by the number of bands i wanted to use (5) then rounded that to the nearest half inch to keep things simple. That gave me 5.5" as a base line. Next I chose 6" as a length for my bands. I just pulled 6" out of the air and got lucky. often times patterning takes a few tries to get it right. From there I added another 1 1/2" to the base and drew in one half of the profile I wanted. Next i cut out that half, folded it over, traced it and cut out the other half. Now trace that out 4 more times and cut them all out.

For the disc that holds them together on the top I just traced the lid off a jam jar that looked to be the right size. It was very complicated scientific process

Now tape them all into place on your brow band to get an idea how they fit. they will likely need to be tweaked, you may even have to go through a few sets before you get it right.

Congratulations, that's the top of you helm. Once your happy with it it's time to move onto the cheek plates and the nasal. I'm afraid that there really isn't much in the way of measurements for these. Look at pictures online, look at your drawings and just start cutting out pieces until get something you're happy with. Don't be afraid to look like an idiot in a cardboard hat and try it on to make sure you can move your head, and that nothing is in the way of your eyes.

I opted to put a slat back on this helmet instead of the skirt plate that I had in my drawings, again, just like the cheek plates and nasal they are something you just have to eyeball. It seems i didn't take any pics of them getting patterned, but they're pretty simple. make a rectangle about 1"x5" and your pretty much there. if it wont be hidden maybe ad a bit of pizazz to make them look nice, and just make sure they aren't so long that you cant move your head properly.

Step 3: Layout, Cut and Clean your plates.

Now that you've got everything patterned out it's time to cut it all out. Start out by tracing it all out onto your steel, make sure to place your pieces to minimize the amount of waste. This was especially important for me since I had just BARELY enough steel to finish this helmet.

Once your happy with the layout fire up your jigsaw and start cutting out the brow band, bands and top. Do not cut out the cheek plates, nasal or slats until you have the dome of the helmet assembled.

Once you have all your top plates cut out clean up the edges and put a nice bevel on them. You don't want to have any burrs or sharp bits anywhere on them. Any point that may come in contact with you should be rounded out.


Step 4: Building the Frame. pt 1: the bands

Now that you  have the brow band, spangen bands and top piece all cut out and cleaned up it's time to shape them.

First off you can make life easier by drawing a guide on some scrap paper. Draw a line that is as long as you want your helmet to be front to back, then bisect it with one for the width. Next eyeball in an oval around it to give you a rough idea of how your brow band should be shaped.
Next take your brow bands and giving them a quick once over into the shallow dish. This should give you most of your curve from end to end and just a tiny tiny bit of curve top to bottom. Now take your brow bands and lay them over the guide. Tweak whichever one of them is the closest match until your happy with it's shape, then clamp the other band to it and work your way down from the clamp adjusting the curve until they are symmetrical. You should be able to just bend them by hand or over your thigh.

Once they are looking nice and even you can set them aside and start on the bands.
To shape the bands just give them 2 or 3 passes in the shallow dish. Start at the outside, work your way into the middle and they should all come out close to the same shape.

Now it's time to temporarily assemble it. here is where Clecos become the greatest thing since hot and cold running water. if you don't have Clecos then you'll be wanting a whole bunch of nuts and bolts in whatever size rivet you'll be using.

So, start by laying your brow band out on the workbench then take the one of the band sections and place it on top front and center to check the fit. Mark where it needs to be tweaked then use a rubber or dead blow mallet to adjust the curve over a T stake as needed. do it a little bit at a time and keep coming back to check the curve.

Once you have the fit right clamp everything in place and mark where you're rivets will go. Then center punch and drill the rivet holes in the brow band. Once your holes are drilled give them a quick once over with a half round file and use them to mark their matches on the spangen band. Center punch and drill those holes, then use either Clecos or nuts and bolts to hold it all together.

Now just work your way around to the back repeating the process with each band. At that point you will most likely have 1/4" or so of extra poking out from the brow band. I used a combination of tin snips, the grinder and a file to take off that last little bit and leave it sitting flush.

Step 5: Building the Frame pt. 2 the top plate

The top plate has a couple of steps that the bands don't. First, give it a quick once over in the shallow dish, that gets the steel to start moving and makes the next steps easier. Once it's been shallow dished move it over to the deep dish and give it a few more passes. You can stop here, but I figured I'd give mine a little something extra and add a little boss to the center. To do that I cleaned up the edges of an appropriately sized hole in a hunk of steel (actually the base of my T stake) then centered the top plate over it. Next I placed the  ball end of my riveting hammer in the center of the top plate and gave it a few good smacks with the shallow side of my dishing hammer. You should be left with something that looks like a tiny UFO.

Now place it on top of your bands and check how it fits. Odds are it wont. Thankfully you should still be able to bend and twist your bands as needed to make it fit. Something else that will really help is to bend the tips of the bands up with a pair of pliers so they fit into the top plate rather than under. Once your happy with your fit mark punch and drill your holes, then bolt it all together.

Step 6: Finishing the Frame

Now it;s time for some planishing, maybe a little riveting, and some more patterning.

First off, planishing. I could have planished the plates separately in step 4, but I prefer to have everything roughed into place first. it's really a matter of preference though.

To planish your frame you'll need a planishing hammer, Mine is a plain old storebought autobody planishing hammer, but it's the heaviest one I could find. what you want for a planishing hammer is a light to medium weight hammer with a broad flat face and as close to a mirror polish on it as you can get. Any imperfections in the face of this hammer will be stamped into your work piece a few hundred times over.
The actual mechanics of planishing are pretty simple. You place your workpiece over a ball stake (usually) and start using light taps with the hammer to pinch the metal between it and the stake. I swing about 90% from the wrist and 10% from the elbow. you should have a light grip just enough to control where the hammer falls and not have it fall out of your hand. You'll figure out where the right place to hit is pretty fast, it should make a kind of a "ting" sound and you should be able to use the bounce to reset the hammer for the next stroke. If your not hitting right the sound will be a little more flat sounding and the hammer will either not bounce well at all or bounce off to one side or the other.

Once you've established where to swing the hammer you just keep swinging the hammer at that spot and move the workpiece under it. The object is to hit pretty much every bit of exposed surface area, this should change the little lumps left over from dishing to an even texture of tiny facets. usually it takes a few passes of this to get everything looking nice. From there you can either leave it as is, which is what i like to do, or you can sand and grind the corners off those facets leaving behind a smooth surface ready to polish.

Once your frame is planished you have a choice to make, you can just reverse your bolts/clecos an go straight to patterning out the panels, or you can do your finishing work on it and assemble it.

I chose to burnish it all and rivet it together before patterning the panels.

In preparation for riveting I re-assembled the whole thing with clecos, but I used the bare minimum to hold it all together. From there i worked my way around all the open holes in the brow band, then I went riveted on the top plate. Next I removed most of the clecos and riveted those spots. I did however leave a few places on the brow band un-riveted. There are 4 rivets on the front that will be shared with the nasal, so I left them open, and 2 on the back where the clecos and a bit of scrap are holding the back shut untill I have the pannels riveted in.

Step 7: The Panels

Now that  the frame is together it's time to pattern out the panels. Patterning out the panels is dead simple, just lay the frame on some patterning material (in this case old cereal boxes) and trace out each of the openings. After you trace out each opening add 1/2" to 3/4" of rivet allowance. You also want to make sure to mark which panel is which, and that the marked side will be the side that faces inside the helmet. tThis is because odds are the panels wont be perfectly symmetrical, and they may not fit properly in any of the other spaces.

Once you have your patterns transfer them onto your steel, cut them out, finish the edges then give them a couple passes in the shallow dish.

After I had them dished I marked, punched and drilled my rivet holes in the band. 14 for each panel. It's a little overkill, but it looks sweet.

After you've put the holes in your bands it's time to fir the panels. If your lucky they'll just slip right in. I was lucky for a few, but a couple of them needed some serious man handling.

I started with the back panel. Lucky for me it fit right in place without any tweaking, so I held it in place, marked a few of the rivet holes then  punched and drilled them. Once they were drilled I used clecos to hold it in place and used the remaining holes in the bands as my guides to drill the rest of the holes.

The second panel didn't fit so well. It needed some more curvature added to it. To add that extra curve i just used the jaws of the vice and a little muscle to tweak the curve into place. Bending it with the vise let me get it pretty close to fitting right, but the top corner was still out of whack. So i drilled the holes for the side that fit right, then put clecos in each hole to hold it in place. Next I put it over the ball stake and used a rubber mallet to try and knock it into alignment. That got me about half way to where I needed it to be, so I finished it by reaching through with my dishing hammer and bashing the panel the rest of the way into place from the inside. once I was happy with the fit I drilled the rest of the holes and moved on.

The last 3 panels all went in pretty easily. 2 of them needed some light tweaking with the hammer, but nothing major.

Once they were all fit I planished them and then it was time to move onto the cheek plates and the slat back.


Step 8: The Lower Half

Now that your top is all worked out it's time for the bottom.
Start out by checking your patterns for the nasal and cheek plates to make sure they work with the metal helm top. I needed to go back and re-pattern my nasal.

Once your happy with how your patterns look with the top cut them all out.

Now, take your cheek plates and give them a pass or 2 in the shallow dish. Look st the pictures to see about how much curvature you're looking for. Once you've dished the cheek plates you'll need to put a flare along the back edge. Well, you don't need to, but it looks good, is easy, strengthens the plates and will help deflect weapons away from the opening at the back of the cheep plate. So really there isn't any reason not to.

To flare the edge start by marking the line you want to flare it on. Next place the line on a soft edge (in this case the edge of the dish, the edge of a stump or even a 2x4 clamped in a vice will work too.) and start to hammer the edge down. Just do it a little bit at a time, I used 2 passes to set the flare on these plates.

Once your cheek plates are all formed mark and punch the holes where they'll attach to the top and bolt or cleco them in place.

Next we'll do the slat back. Start by giving them a quick pass in the shallow dish, that will add a bit of compound curve to them and make them a little stronger, plus it looks better IMHO. For a bit of extra flare I embossed little bosses into them the same way I did for the top plate. next drill a pair of holes in the top corners of each slat and mark and drill matching holes in your helmet top. I just spaced the slats evenly around the back between the cheek plates, it worked out to be a little less than an inch between each slat.

The slats by themselves are still fairly easily bent, so to beef them up I put a reinforcing bar across them. To make it I eyeballed out a length of 3/4" bar stock and used a modified machinists hammer to stretch one side, causing it to curve into more of a cone shape. the pictures explain it better than i can.
Once you have the right amount of curvature in it mark and drill your holes, then bolt or cleco it in place.
I ended up having to add as second bar underneath the first, just above the bosses to make it SCA legal. i don't have any pics, but it was done exactly the same as the first.

Lastly We'll do the nasal. I started by creasing the nasal. To do that I marked my center line as far up as i wanted the crease to go, then clamped it into the vice and hammed it over a little. It's that simple. Next I dished top portion of the nasal a little in the shallow dish, that makes it sit nicely against the top of the helm.
Once i was happy with the fit I marked the existing holes in the brow band on it, drilled them, then while the nasal was held in place with clecos I marked and drilled the other rivet holes.

That's it, all that's left to do at this point is your finishing and assembly.

Step 9: Finishing and Final Assembly

Now that your helmet is all shaped and has all the rivet holes all that's left to do is your finishing. Whether you paint, powder coat, blacken, blue, russet, polish or whatever else is up to you. Myself, I take advantage of an industrial tumbler to burnish my plates.

Once you've done whatever finishing you choose it's time for the final assembly.
Start with the dome and cleco or bolt in a panel, then go over it and one at a time remove each fastener and replace it with a rivet. Start with the back panel and work your way to the front just like you did to make all the holes in the first place.

Next put on the cheek plates, then the slats. Last comes the nasal. If your adding a bar grill or something similar then obviously that should go on before the nasal.

I was going to do a step on the bar grill, but I'm not happy with how I made mine, there was a lot of frustration and swearing involved. Understandably I don't want to make a tutorial on something that I'm not too sure about building myself in the first place. I'll see about a bar grill 'ible when I make my next helm.

Profoundly influenced by your design, I set out to create my first real metal project by simplifying what I saw here to suit my lack of tools and experience. This turned out to be my stepping stone into further metalwork and historicalish fighting as I'm now working on a harness of my own design.
Thank you, and keep going!

How about instructions on a simple ROMAN RED PLUM Helmet???
Methelas4 years ago
Good to see more SCAdians here on instructables. I thought i was one of very few.
Which reminds me, about how much would you sell that helm for, i'm looking to buy a new one.
armourkris (author)  Methelas4 years ago
I know there are a few of us kicking around here, but the more the merrier. i think there is a group of SCA related instructables even.

I've actually still got that helm for sale, I'm asking 300 for it. For custom work the price goes up a you get fancier, and down to 150 for a bare bones 4 panel spangen.
Do you know where the scadian list is on here?
http://www.instructables.com/group/SCA/
armourkris (author)  southerngent4 years ago
I'm afraid I;ve never been able to find it on purpose. I just stumble across it by acident once in a while and never remember how to get back to it when i want to.
you may have mentioned this in the instructable, but are your rounding dishes/swages made of aluminum or lead? did you make them? and how? I'm working on maille for a replica of the Gjermundbu helmet. you also may have mentioned this, but what is the best gauge of steel to work with, for a "battle ready" helm? or even armour. I have plenty of 16 gauge and some others... Thanks :D
armourkris (author)  OldOwlIronworks4 years ago
I've got 3 dishes, deep, medium and shallow. I made the deep dish by welding a sheet of 3/16" steel over a section of 4 inch pipe, then I heated it up and bashed it into a dish with my shot-put on a stick. I used the backside of it as a mold for my medium dish and poured down melted tire weights into the backside, let it cool and knocked it out, the shallow dish is just the bottom couple inches of a coffee tin with melted tire weights poured in then i just bashed away at it with my dishing hammer till it was about 1/4 inch or so deep. the tire weights are some kind of lead alloy. it's harder than straight lead so it holds up pretty good for dishing into. plus, with a bit of time you can scrounge them up for free off the sides of roads and whatnot.
As for what thickness of steel you want to use, well, that depends on a few things, what kind of use will it see, how hard will it get hit, are there pre-set requirements you need to meet. MY sca heavy helmets are all made from 14ga, my rebated steel helmet is 16ga, and my bike helmet is 18ga.
for a bit of a general guideline, assuming you're using mild steel, I'd go with...

Helmets 16 gauge minimum if you plan on getting hit, 14 gauge is better still. the weight is what stops you from getting a concussion after all.
For gorgets(neck armour) 18 gauge is usually a safe bet.
for 1 piece breastplates i use 16 gauge
back plates i go with 18 gauge
faulds and tasstes i use a mix of 18 and 16 gauge.
multy-plate breastplates and coat of plates style armour i use 18 gauge
spaulders/pauldrons(shoulders) i use a 16 gauge main plate with 18 gauge lames
elbows/knees are usually 16 or 14 gauge, with 18 gauge lames
vambraces (forearms) i use 16 gauge for the bottom half, and 18 gauge for the top.
rebraces (upper arms) i usually use 18 or sometimes 16 gauge.
cuise(thighs) I use 16 gauge, sometimes with 18 gauge wrap plates
greaves(shins) i use 18 gauge
sabatons(feet) 18 gauge, maybe 20.
gauntlets i usually mix 16 and 18 gauge

scale and lamellar armour i use 20 gauge, 18 at the thickest, but weight adds up fast with these.

in the end you're trying to find a ballance between coverage and weight. My current harness covers me from head to knees, minus my upper arms. it weighs about 60 lbs, i figure that adding greaves and finishing off the upper arms will bring my up to about 70 lbs. I only weigh about 150. I feel this is pretty reasonable for a full suite of plate armour, then again, i also like throwing 3 or 4 days worth of gear on my back and slogging up steep mountains, so what works for me may not work for you.

wow, thats a long comment now, hope something in there helps.
Oh yeah another quick question :D
I have my templates traced on the 16 ga. steel, and in the book "medieval armor reproduction" it said to use a beverly shear Or a jigsaw...can I use a plasma cutter? I have a small jigsaw, but in short, it sucks, and I do have access to a plasma cutter.
Thanks
armourkris (author)  OldOwlIronworks4 years ago
yea, go for the plasma cutter, they're fun tools. really you can use anything that'll cut your metal, I usually use a jigsaw, tin snips and cold chisels, but only cause I don't have anything better.
I was also thinking about Acetylene, but I am kinda afraid that'll take a bit too much metal off, I guess it can't hurt to try on some scrap
armourkris (author)  OldOwlIronworks4 years ago
I wouldn't bother using acetylene for cutting sheet metal, you'd need a tiny tiny tip for the thickness you'll be cutting, and you'll probably be left with a lot of cleanup. in my experience oxy fuel cutting isn't really worth wile for anything thinner than 1/4". That said, if you put down nice welds with it it's great for welded pieces and bar grills.
Thank you! That helped quite a lot! I will have to make some dishes now; scrapyard trip :D
A Whitney punch is the only way to fly for me. Center punch the holes, then punch them with the Whitney. No burrs to clean up, and no file scratches to smooth.
Mrballeng4 years ago
Have you ever tried your hand at making a container. Some type of chest, box, or keepsake? Good work.
I've thought of it, but no, I've never actually gotten around to making anything that wasn't armour
armourkris (author)  Rozarius4 years ago
and i should really start to check whether me or the room mate are logged into instructables before replying to questions
JP505 years ago
Great job!  I need to ask what type of rivets are you using  and  where are they available?  I have done lots of welding,  gas and mig,  but have never seen that style of rivet.  Thanks.
armourkris (author)  JP504 years ago
since i cant find anywhere in canada selling affordable rivets i just use plain old bright finish nails, i get them is the shortest lengths i can in 1/8" and 3/16" diameters, i know 6d is 1/8, but i cant remember what the 3/16 is off the top of my head. from there i just clip them down to length and peen them like any other solid shank rivet.
check out my riveting instructable for more retailed info.

armourkris (author)  JP505 years ago
Just what pietseekoe said. they are 6d nails cut down to length and hammered down.
pietzeekoe JP505 years ago
i think he just uses nails that he cuts and then hammers down

What may help you on your bar grill is a wooden swage plate, I'm going to write an instructables on one one as soon as I get pics, but I drew one up for you.

It's just layered up plywood glued together, mine's about 10 years old and has seen weekly use.

If you lay your bar grill out flat and weld it together first, then shape it, things are alot easier, use the swage plate to get specific arcs, make yourself two or three of various sizes.  They are great for shaping vanbraces and grieves or anything else with a uniform curve.

armourkris (author)  Rune Cutter4 years ago
hat is a brilliant idea, I;ve been wishing I had something like this for a long time, but it never occurred to me to make one out of layered plywood. I guess I;m going to have to scrounge up some plywood now
wulfric4 years ago
Wow your spangen is quite good, but if the marshals have a good look at your rivets they may not pass inspection. There is a company in the States called McMaster Carr, They sell solid steel rivets that one can't seem to find in Canada. The problem is they don't ship up here, but if you have a friend or whatever to ship them to they could forward them to you, or bring them across for you when they come up for a visit. The iron in nails is just too soft to hold up to SCA combat. Very good looking work keep our fighters armoured and on the field.
armourkris (author)  wulfric4 years ago
I've built all my own kit for the last 10 years, and built gear for a number of other people as well. I've never had a rivet fail, or had a marshal say anything bad about my rivets, I;ve even told a few of them that they're made from cut down nails. it may just be my part of the world, but i gather it is a fairly accepted practice. I also tend to over build things though, so that may be weighing in on my favor. I believe current regs state that rivets can be no more than 2" apart on helms, but on this one they are spaced at just under an inch apart.
that said, on moving parts like elbows and specially knees I'd move up to a 3/16" nail.
Thanks for the heads up though
awesome. Great work
domamir4 years ago
I have a question. Is this a SCA legal heavy combat helm?
armourkris (author)  domamir4 years ago
It is indeed. now i just need to find someone to buy it.
Where are you located? All you really need to do is go to your local fighter practice and you may find some who would want it or some other type of helm, or arrmor parts.

Have you ever thought of making small ones and selling them at craft fairs? You could make them out of tin that would reduce on the cost and the time spent on making them being that tin is enormously softer than steel. I am currently making a full sized one out of copper that i had laying around so i hope it comes out the same. Over all this is a great Instructable it is very detailed and has a lot of good quality pictures which is good for a visual learner like me. Keep up what your doing i hope to hear more from you.
unanonymous5 years ago
awesome now if only i could convince my dad to let me make this(i use his account)
hmmm I wonder what gauge sheetmetal that is used for making duct work is.

my dad has like 300 plus square ft. of scrap metal.

I know you don't entirely need a dish but how would I get or make one?
armourkris (author)  the_burrito_master5 years ago
most duct work steel I've seen is around 20 gauge, that said there isn't any reason you couldn't make a dress helm out of steel that thin

the dish that i made the majority of this helm with was made by melting down a bunch of tire weights i scrounged up and pouring it into a coffee tin. Once it had cooled off i just cut the tin off about 1/4" below the level of the lead then i just hammered stuff into it untill a shallow dish formed. i think it;s only about a centimeter deep.

other ways of building a dish range from carving or cutting a bowl out from a stump. I used to have a chunk of cherry wood that i cut a bowl into by repeatedly plunge cutting into it with a skill saw, I;ve also got a dish made by welding a piece of 1/8" steel over some 4" pipe, then I heated it up with a tiger torch and bashed it into a dish with a shotput. the deep dish i use in this instructable cast lead again, but using the pipe and steel dish as a mould. Another common way is to call up some compressed gas companies and find out what they do when they dispose of old tanks. most places cut them in half and toss them or sell them for scrap. if you can get the bottom half of an old cylender they usually have a nice ready formed dish in them, just weld a bottom on, or stick it in a barrel of sand, use a dremmel to clean up any lettering sticking out form the dish section and you should be good to go there.

so yea, dishes arent to tricky, most anything bowl shaped and tough enough to hammer steel into will work.

For shallow cirves like in this helmet you could also probably go the sandbag route. just take a pair of old jeans, double up the legs, stitch one end shut really good then fill it 3/4 or so with dry sand or bb's, or buck shot or anything like that and stitch the other end up. lay it out like a pillow and you can do light dishing into it,
Finally got around to making a dish!

I cut the bottom of a refrigerant tank off and hammered the bottom into itself. it dishes amazingly ,I  cant believe how easy it has become. only problem is it had 3 nubs on the bottom that I had to hammer down and they made little warps in the dish I didn't notice any problems as I dished a little piece of metal...
HNI_0009.JPG
duct work steel is about 20 g  your correct, it is a bit thin for anything except a dress helm and difficult to dish without crinkles. I found sheet steel cut outs from a custom van place and it is 16g. and dishes nicely
I was out at one of my local auto wrecking yards and found several "dead" H tanks the big type they use for welding and Co2 fire control banks. These had been drilled and dumped for scrap. I had them cut off the very end of the bottom about a foot from the bottom actually. The bottom of these tanks are very heavy and have a perfect "dished" end in them. A little work with a wire wheel and it was perfect. I have an anvil so cut two notches out on it so it sits down in a little slot there on the Anvil. I make helms all the time on it as well as shoulder pauldrons and Knee and elbow cops.
whoa! Dude thanks my dad has a few gas tanks! I cant believe I never thought of that. Thank you so much.

A tree stump sounds good to me too

I should also add that once you start getting thinner than 18 gauge dishing steel gets a little bit more difficult. this is because the edges tend to want to crease and wrinkle. So long as you stay on top of the wrinkles and hammer them out when you see them forming you shouldn't have to much trouble though.
