Blacksmithery on the barbecue? - yes, this really works!

Here's how you can make the quality steel that is found in bicycle parts live on, by forging it into blades to create useful tools. The best thing though is that this can be done on a normal barbecue using lumpwood charcoal and a camping airbed inflation fan as a bellows. It is very satisfying.

Video: superfast skim through the various forging, grinding, carving, sanding and polishing involved, and showing which reclaimed materials were used for each tool.


All you need to get started

This Instructable covers:

1. Making your forge:

  • How to convert your barbecue into a pretty effective mini-forge by adding a simple fan-assisted bellows

2. Basic techniques for simple tool making

  • The basics of forging, grinding and finishing blades from recycled steel bike parts
  • The basics of making handles from reclaimed wood, including green wood

2. Examples of 4 tools made using the methods described, so you can see for real what is involved

  • A simple fixed blade hunting/fishing/general purpose knife
  • A broad bladed carving knife
  • A lightweight folding pocket mushroom knife
  • A portable folding pruning-saw for foraging

Each tool here only took about 8-9 hours to make. I've outlined how I made each tool in a single step that shows some of the specific work that tool needed above the basic forging and handle making.

Step 1: Getting Hold of the Raw Materials

Quality tools from recycled free raw materials...

You really can make decent tools from stuff found lying about unused. It will you cost very little to make and it is a good feeling using a tool you made from discarded materials at virtually no cost. The only real cost was the charcoal used to forge them, though you could even use scrap wood for that if you really wanted to.

Bike parts are used here as they are made from high quality stainless steel. The wood was mostly recycled already seasoned wood (oak floorboards) and in once case, lovely yew from a scavenged log in the woods.

These materials were used. You can easily scavenge similar ones:

  • Blades - a cast off crank axle (high strength steel) and a broken bike lock (stainless steel)
  • Handles - old floorboards (oak) and forestry log offcuts (yew)
  • Ferrules - an Ikea waste paper bin (stainless steel) and a broken towel rail (steel)Rivets for handles - old screws (brass)

A cheap barbecue makes a surprisingly effective forge. The tube is attached to a camp-bed inflator fan which pumps air through the charcoal to superheat it.


Step 2: Tools That You Will Need

The tools used are mostly readily found in many households. Some of the things used here are not essential, but make it much easier. Probably the only thing unlikely to be commonly found is a blacksmith's anvil. I love mine, but you may not be lucky enough to own one. You could improvise on granite or the jaws of a large heavy vice (closed or it may damage it). You could also use scrap metal parts from cars or truck like axles. Anything large, heavy and solid, preferably steel.

  • Dremel with assorted cutting and routing bits
  • Cabinet maker's smoothing scrapers
  • Various grit papers

Step 3: Converting Your Barbecue Into a Forge

Using a camping bed fan as a bellows

Here's how I made the forge. It is pretty basic. You get a barbecue and find a way to blast air through it to fan the flames so they get really hot. I've seen hairdryers used, but this camping fan worked a treat. Whatever you use, it is a simple electric bellows.

You could improve it by enclosing the charcoal to retain heat, by using coal (smoky) which burns hotter or by using a really powerful fan. The principle is all that matters and here's my version so you can see what I did for real.

Cheap and quite tough, a camp bed inflator fan is a great bellows for your DIY forge.


Camping bed fans make good bellows. They are built to pump air for ages and are quite hardy and not esepcially loud. Mine can cope with being used for an hour with no problem. You could use a hairdryer, but they tend to cut out. It will get grubby too, so take care if using your actual hairdryer...

From your fan, you need a connecting pipe to deliver the air-flow into the fire....

(with camping bed fan as bellows)

The business end of your bellows needs to push out air under a bit of pressure to get the fire roaring. A common copper water pipe is ideal. It is easiest to have a 90 degree bend with one arm matched to the length of your barbecue. It has holes drilled and sealed by hammering a double fold in the end.

The other end needs to be long enough to reach your pump. It can't be too close or you'll melt it.

The pipe sits in the barbecue and is covered with fire bricks to help spread out the flow across the coals that sit on top of it. It is better than just piling charcoal on top of the pipe.

Here is the barbecue with air flowing. It gets plenty hot.

Step 4: Basic Blade Making Techniques

Forging blades from recyled parts

All the tools in this Instructable have blades that used to be scrap metal. Most are made from nice stainless steel from a broken D-lock for a bike and one is made from a bike crank axle, which provided super high quality steel alloy. Axles have to be strong and they are typically made from Molybdenum Chrome steel.

Here is a carving slicing knife I made on the barbecue. It cuts like a dream and is broad enough to create even slices.

Slicing/carving knife


This is the broken bike lock it was made from...

To convert this into a blade, start by heating it to red heat. Shove it right i the coals and leave for 3-4 minutes

Heating in the forge


Once red hot, you hammer it to flatten. This doesn't just happen. It will take quite a lot of passes and takes about half an hour. I use locking grips (Mole grips) to hold the end of the steel. They offer a reassuring control. This means you don't drop red hot metal on your foot or have a piece fly off at an angle. Neither are welcome!

It is advisable to wear a glove as even the grips can get hot. You can use one on the hammering hand too, but I like the control you get without one.

Hammering on the anvil


You can see the shape of the lade emerging

First flattening of a blade


After lots of repeated battering, you will find a fairly small diameter piece of steel will flatten to quite a wide blade once it is bashed thin.

Ham slicer on the forge


The best way to figure this out is to do it. Here is the carving knife blade once forging is complete. It will be blueish black.

Ham slicer after forging before grinding


After forging, the rest of the process is about grinding the blade into shape and producing a consistent thickness. The best thing for this is a belt sander. You could use a bench grinder, but the sander is much better as its flat plate helps you keep it even.

Ham slicer on the belt sander


To get fastest results, you need to start with a rough grit (60 grit). Here you can see the first rough grind.

Ham slicer after rough grinding


The tang end (the bit that fits into the handle) needs to have straight edges. This is easy to do on the sander.

Grinding the blade on the belt sander


By reducing the grit size, the grinding will produce a smoother and smoother blade.

Ham slicer blade part-polished


Eventually you can stop grinding to shape and start polishing it. For this, you need a finer sander. I used a random orbit sander. This produces a really fine finish. Again, start with a coarse grit (120) and work down to a fine grit (240).

Fine polishing with the orbital sander


Finally, the really really fine polish comes from using a strop. This is what barbers hone their razors on. Essentially it is a soft surface impregnated with a super fine abrasive grit that acts as a polish. This is easy to make. You just find some scrap leather and pull it round a rounded piece of wood and clamp it in the vice. The abrasive paste is called emery paste. You could use bathroom ream cleaner as that is also a mild abrasive

I've used an old tool handle here for the wooden base.

Strop


To polish, whip the blade back and forth on the strop. You'll be amazed how smooth and shiny it gets

And here it is ready to have a handle fitted. Not bad for a bike lock.

Here is another example. This shows how a pretty tough bike crank axle can also be used. Here i sthe raw object found in the shed.

Mushroom knife on the forge


Being thicker to start with, this took much longer to flatten.

Eventually it ended up looking like this. THis knife needed to be curved. You can see how a basic curve has been hammered into the metal during forging.

Mushroom knife blade after forging


Here are two pieces of metal that have been forged flat. The lower one was used in the end (the axle). If you look closely, you can see the blade design traced onto the raw forged steel to act as a guide for cutting.

The raw forged steel was then cut roughly to shape using an angle grinder.

Mushroom knife blade rough cut


After this, it was shaped further on the bench grinder

Here it is close to final shape. The surface is very roough from the grinder

At this point the desired shape was drawn on again to help guide the final shaping.

At this point, the blade was ready to have a handle fitted

Step 5: Basic Handle-making Techniques

A good handle needs to be made from good wood.

Luckily, you can get good free wood for handles all over the place. The simplest way to do this isto reclaim some suitable seasoned wood. I had a lot of thick old oak floorboards, which were perfect. Oak is strong, tough and takes a really good polish when smoothed down with sanding.

You can also use raw wood from branches, but this is harder as it needs seasoning. I used a yew branch that I found in the woods for one knife. This was from prunings resulting from forestry clearance. This method is more unpredictable as you need to let the wood season or it will crack. I cut it green on the band saw then left it to dry out in my shed for two months. Even this was not really long enough. A year would have been better.

Shaping handles

Method 1 - using reclaimed wood that is aleady seasoned

The easiest wood to recycle is reclaimed wood. It is surprisingly easy to get hold of suitable wood for handles. The most common you will find in skips is probably beech, which makes a great handle. It is widely used in furniture. Oak is slightly harder to work, but is also quite commonly thrown away. Here are some solid oak floorboards I found in a skip.

Oak is often used in older fence posts and can be ripped down into useful sizes as needed. It can be found in the sides of old drawers too.

Oak Planks


To get started, cut a block of wood a bit bigger than you'll need for the handle

Oak plank cut roughly to size, ready to draw the handle profile on


The exact shape of the wooden handle profile needs to match the blade it is intended for. Here is a blade of a folding knife being used as a drawing template to ensure the handle works with it

Designing the handle shape to match the blade profile ()


The handle should be drawn to scale on paper, and then it can easily be transferred to the wood using the old classroom tracing technique. On the reverse of your drawing, rub soft pencil, then place the drawing on the wood and draw again with a hard pencil to transfer the pattern

Designing the handle shape to match the blade profile ()


You can cut the pattern out using a fret saw or bandsaw. I used a chisel, but used stop cuts to prevent accidentally splitting the handle. This can happen quite easily otherwise, if you accidentally over-hit the chisel along the grain.

Cutting stop cuts


Here is the same handle after rough shaping with the chisel.

Carving a handle to shape


The real detailed contouring is done on a belt sander. This will produce a smooth result. You need to work the handle over the moving belt starting with a coarse grit (80 or less) then change belts to finer ones (down to about 120 grit). Eventually, you can also switch over to the finer orbital sander (in the background) and really smooth it down with 240 grit.

Here's one that has been roughed out

Here is the raw cut out of one handle

After further sanding, the rounded contours are shaped up

Then the blade end is subtly sanded to match the blade.

Mushroom handle - ferrule barrel shaped


Here is another handle after final fine-sanding. This is yew, which has an awesome grain, although is more prone to splitting.

Yew handle after fine sanding (hunting knife)


Finally, varnishing is not essential, but protects the handle from moisture changes that can make the grain stand out and the handle feel veiny in the grip.

Varnishing fine sanded oak will stop moisture getting in and raising the grain


Method 2 - using raw wood from branches

This method is much less predictable as you have to season the wood. This can take a year or more to do properly, but you can risk it with small pieces as they dry out quite fast. I left this one for about 2 months and got a few minor cracks.

First cuts to square it off...

The same log with all bark removed and edges squared lengthways. The wood needed is the lovely reddish heart-wood. This is the hardest part and best for making the handle. It still needs to be stored in a cool dry place for a long time. 6 months to a year would be best.

Fitting handles

The blade of the knife needs a recess in the handle to be fitted. This can be cut out using a dremel.

Routing out the blade recess in a handle with a Dremel and a tungsten burr tool


As it progresses, you need to check the fit...

Checking handle fit (carving knife)


You can use a drill for this too. This is better for the initial cutting out but not very good for subtle finishing.

Drilling out the handle recess (hunting knife)


The stubby end of the knife (the tang) should be checked for fit as you go.

Here it is looking almost done.

Finally the handle needs fixing. Here is the same knife with the handle and tang drilled while fitted together, with rivets in place, ready for hammering

Step 6: a Simple Hunting Knife From Bike-lock Steel

This was my first attempt at making a knife totally from scratch using reclaimed materials. It's not perfect, but the things that didn't quite work taught me a lot about how to improve the process. It was a test project really.

The knife is a simple, stout, tapered stainless steel blade set in an oiled yew handle. I use it for fishing and gardening as a general purpose knife. The blade is not hardened so that is can be sharpened on stones easily when out and about and that works very well.

The steel for the blade was forged from the abandoned U-shaped part of a standard bicycle D-lock

I use it as a rough knife round the garden. It is good for cutting under the tap roots of dandelions.

Hunting knife


But it is also quite nifty for cutting veg like this onion.

Hunting knife


You can tell this was a pilot experiment. I didn't worry too much about grinding the blade perfectly. I quite like the obvious sander marks.

You can also see a tiny crack in the handle. This was partly caused by using inadequately seasoned green wood - yew wood from a log out of the forest.

Step 7: A Folding Pocket Saw for Foraging

This is an awesome tool. I made it for cutting sticks in the woods whilst out walking It's really light and portable, but lethally sharp and makes light work of sticks and even small branches

Folding saw and cut branch


Cutting a thick branch for a future tool handle. This is a holly branch, just under two inches thick. It has a curved blade. This allows the blade to be used on the draw (pulling towards the body). This was deliberate, because it is safer to pull you hand out of a hedge firmly, than it is to push it into a hedge firmly!

Folding saw in action


Apart from the basic forging and shaping described earlier, this tool also needed to be portable. The handle is quite thin to keep weight down. It is made from oak, which allows it to be quite delicate due to the wood's high strength.

The other obvious need was for it to fold away. Here is the design drawing. The curved blade has been redrawn in various positions to check it will work.

Saw handle blank and blade


Oak is good for a tool with a folding blade, as it is very strong. But even oak needs reinforcement. This is done with a steel ferrule (a split cylinder that encases the hinge). Here you can see the handle being shaped to accept the ferrule.

Cutting ferrule barrel into handle


Here the slot is being cut to form the hinge with the end of the folding blade

Cutting blade slot


Once the blade was fitted, both the handle and blade needed to be drilled whilst in final position.

Drilling ferrule hole


The ferrule was cut from a piece of an old towel rail using a dremel. A hacksaw would do this too.

Cutting ferrule


The ferrule was cut lengthways to allow the hinged blade to pass. Here it is being tested for a good fit.

Ferrule


The hinge was completed with a cupboard joining bolt from an IKEA cupboard. This is a bolt with a threaded cylinder to match. They are used to hold adjoining cupboards together in kitchens.

Here is the finished saw with ferrule and blade hinge locked in place

Finished ferrule with blade locked in place


Of course, this is a saw, not a knife. The raw blade before filing teeth looked like this.

The saw teeth were filed with a small, standard 60 degree triangular saw

Step 8: A Carving Knife/ Ham Slicer

This is the least complicated knife described here, but I love its elegant simplicity. It has a rounded tip to avoid injury and give a grip if needed. There is a small finger space at the end of the sharpened blade to allow control if needed. The blade is deliberately wide so that the slices come out nice and smooth and even. This also helps transfer cut food from board to plate.

I love using this. It glides as it slices. It's a joy. It is featured in the step on forging and handle making so there isn't much to add here.

Step 9: A Folding Mushroom Harvesting Knife

Mushroom knife showing folding action


Making this was one of my favourites. It's based on a rather obscure and specialist knife made by the legendary French knife company Opinel.

It is a little over 3" long when folded and very light for carrying about in the field. I made it for a friend who shares a passion for foraging mushrooms. He always finds huge Ceps when he is out. This is the tool for clean-cutting the fruit off the stem without disturbing the underlying mushroom roots network (the mycelium).

Here you can see how the short curved blade allows you to get a clean cut through the stem of a mushroom easily

Mushroom knife in action


The lock ring is the characteristic element of an Opinel knife and this was tricky to reproduce. This took quite a few attempts with various methods, before I worked it out.

The steel for this was cut from a stainless steel pedal bin from Ikea. A groove was created by hammering the steel plate over a nail, then shaping in a vice.

Forming lock ring


And shaped with a cold chisel

Forming lock ring


Finally, once the groove was formed, the sheet was hammered round a metal tube to form the ring. The steel you use needs to be a bit springy if possible as this ring needs to be opened up slightly to fit it later.

Step 10: Conclusion

Hopefully the example here show that a barbecue really makes a viable small scale forge. Love to get feedback and links to any you make

I'm going to get set up this spring. Thanks for the good Information.
great, I really enjoyed doing this. It is VERY satisfying making tools like this
<p>Interesting reading nice work and shows how easy in could be</p>
Thanks. Yes it was pretty simple. In the meantime, I realised that if you just want a decent hard steel blade and can't be bothered forging, you can use the steel from a disposable hand saw.<br> <br> Here's a cake slice I made:<br> <br> <a href="http://makingweirdstuff.blogspot.co.uk/2016/04/time-boxed-cake-slice.html" rel="nofollow">http://makingweirdstuff.blogspot.co.uk/2016/04/time-boxed-cake-slice.html</a><br> <br> <br> <br>
<p>Great, im hoping to get into forging soon, ill let you know if i try any of these designs</p>
<p>very impressed with how you wrote this. it's easy to see you put a lot of thought into it. with your forging, i'd seriously suggest gravitating away from charcoal briquettes and find charcoal lump. briquettes are manufactured with clay binders and chemicals to make them burn slower and all that has a propensity to cause excessive pitting and uneven heating. if you're wondering, i picked that up from abs master bladesmith wayne goddard in his book &quot;the $50 knife shop&quot;.</p>
<p>Thanks - yes, I agree. Lumpwood is great. I was getting rid of old briquettes.</p>
<p>oh, well that's understandable!</p>
<p>I'd like to try coal next, but not on my barbecue. I have to eat off that!</p>
<p>lol ohhhh yes. NOT on the grill. if you're gonna try coal, i'd suggest getting it from centaur forge. it's$50 for a 50# bag, freight included. then again, their coke is the same price and it burns hotter and cleaner with less smoke and fumes so you may as well get that instead.</p>
<p>Thanks. Yes, I've heard coke is the one to go for, if I want the hottest and cleanest burn. I'm in UK, but sure it's available heer. I'll check it out</p>
<p>You may want to try using an old worn out brake drum from a truck for your forge .I have seen other instructibles where they have done this . ( look them up ) You could probably find old brake drums really cheap , or even free if you look around . Yes , coal will likely give you a hotter fire , but depending on which grade of coal you use , you can get a lot of nasty smoke that you don't want to breathe . Be safe !</p><p>Cheers , take care , and have a good day !!</p>
<p>Nice instructable. Definitely a lot of good info there. I always like seeing what people come up with for recycled steel.</p>
<p>Thanks. The axle steel is really good stuff. I didn't worry too much about hardening and tempering on these. I was wondering, when you forge high molybdenum steels, do they get changed much by reheating?</p>
<p>i saw this and have to add my 2 pence worth. i hope you don't mind. anyroad, from what i know, molybdenum makes the steel hard to move under the hammer so a steel that's <em>high </em>in molybdenum....well, i hope you have a power hammer or someone you can trust as a striker cus you'd need one or the other. besides, heat treating something like that takes a temperature controlled oven, gradually bringing the piece to critical, giving it a good long soak followed by plate quenching. it's not what the general blacksmith/bladesmith uses. </p>
<p>Hey thanks. All thoughts are welcome. I just left it in the fire until really hot. It was quite hard work, but a long as hot enough, you can get it a bit flatter each time. Talking of bladesmiths, have you seen this BBC video. It's awesome</p><p>http://www.bbc.co.uk/programmes/b05tpw1j</p>
<p>thanks for the link! no i've not seen it yet, but when i get a mo i most certainly will.</p>
Don't get me to lying, I have no idea. I'm assuming you're talking about chromoly type stuff, I don't think I've ever forged any. I've just gotten into forging recently and mostly work with mild steel or recycled agricultural steel like mowing/plowing blades. <br><br>Interesting question though, maybe someone that has a clue will be able to answer it.
<p>I have worked with a lot of metals/alloys over the years and , not being an expert , I do know that there are particular techniques to achieve the hardness you desire . Usually you need to figure out what you want of this item . A lot of times if you make it too hard , it will be too brittle and will break instead of bend . Then again , not being an expert , I have worked with pure molybdenum , and after being exposed to high heat , like 1600 degrees C or more for long periods of time , it gets as brittle as an egg shell . Anyway there are probably a lot of articles on the internet about getting the hardness you want out of whatever metal alloy you are working with .</p><p>Cheers , take care , and have a good day !!</p>
<p>Cool, thanks. I have done a bit of chisel making before, using broken files. These are pretty hard carbon steel and make good chisels. With those, I hardened them by quenching from red heat in water or oil, then temper them back to slightly less hard/brittle by warming in a low oven (can't actually remember the temperature. I thought it was about 150C)</p><p>Found this page on web, which is quite useful:<br><a href="http://www.threeplanes.net/toolsteel.html" rel="nofollow">http://www.threeplanes.net/toolsteel.html</a></p>
<p>Thanks , very informative article . It sounds like you have a good understanding of hardening and tempering . If you are recycling old bicycle parts , for instance , you may not know for sure what the alloy is , and exactly what temperature you have in your forge , you would need to ( as a musician would say ) play it by ear . </p><p>Cheers , take care , and have a good day !!</p>
<p>An actual blacksmiths anvil would be really nice . I have a foot-long or so piece of recycled railroad rail that , maybe not quite as nice , is good for an anvil to pound on things . If someone were to look around and use a little ingenuity , like you do , there are a lot of things that can be re-purposed to make useful things ! </p>
Railroad = Great idea. I have seen the side of a sledgehammer used too<br><br>
<p>Thanks for the the reply . Actually , my &quot;handle &quot; is a typo . It was meant to be &quot; neonharp &quot; not &quot; nwonharp &quot; but I fat-fingered it , the &quot;w &quot; is right next to the &quot;e&quot; , and don't know how to change it now , but I guess it will be ok LMAO . I also like to dabble around with music , and that is how I came up with that name . I wrote a song called &quot; neon &quot; on the &quot; harp &quot; ( harmonica ) :</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/-ehwQmpf4qI" width="500"></iframe></p><p>There are other songs on my UTUBE channel that me and the boys did , I hope that you watch and enjoy them !!! </p><p>Cheers , take care and have a good day !!</p>
<p>nwonharp has a good ring to it though :)</p>
<p>Very edacatinal instructable. you did a great job and covered alot! </p>
<p>Thanks - it took quite a while to do this one, so glad you liked it:)</p>
<p>You should use lump charcoal instead of briquettes. Briquettes have a lot sulfur in them because it reduces the ignition temperature of the briquettes. Lump charcoal is harder to light, but doesn't impart sulfur (which can make steel brittle).</p>
<p>Thanks. Yes, I agree. I was using up a load of briquettes I had and it worked well enough. Lumpwood is much better, and it is better for cooking on too, which is good. One of the best things about using a BBQ to forge on , is that you can cook dinner on it afterwards!</p>
<p>Parang machetes often have their handles glued to the tang simply by packing the hole that is formed and burned with the tang full of plastic shopping bag scraps. Give the tang a final heat, insert it into the handle, sight down the blade for a good fitment then cool. Users swear they don't come apart and hold fast.</p>
<p>I love that idea. Essentially recycling bags to make hot glue - epic!</p>
