'Never stop training' is one of my favorite quotes.
'Making errors is fun - you'll do it much better next time' is also one of my favorite quotes.
'When the going gets tough, the tough get going' is ... also, yes.
But my ultimate favorite is 'Never say no to a beer'.

Whatever, all that to say that since I'm (trying to be) a professional handyman I never bothered about parking my car faaaar from the worksites
- because I'm too lazy to keep on searching a decent parking spot for hours
- because I'm too maso - or stupid - and I don't care about carrying my heavy toolboxes
- because I'm too evil to give my occasional collegue the pleasure by accepting easy jobs 'learn it to do the hard way, it'll be a lot easier later'

So I do a lot of jobs crossing the city walking - 'Never stop training' you know...

But. All that time of walking workout a great part of my anatomy was left unexploited. Well, no, not thàt part ;), but my bàck - a virgin field that bagged for fertile seeds. My hands were full, but why should someone who carries a nice North Face backpack during mountain treks should need to carry stuff in his hands in his working time?

So I tried several classic backpacks. Last time I did I had a fresh sharpened chisel in my pack and guess what happened when I unloaded my back... Right, that thing perforated the fabric and ripped my arm.

Making errors is fun, I said once. Forget what I said. It's not.

That was the last time I did that backpack thing the stupid way. Things had to change. I looked on the net, found what I looked for, checked the next day because I thought there was an comma-error on the page - which wasn't, checked my counts, got insanely drunk once again and in a beer-ised mood I decided to build my own.
A lot of artists take good decisions being influenced by smokeable, drinkable or insertable stuff. Really. So why shouldn't I?

So here's a way to build a nicely portable, relatively cheap, heavy duty yak-proof toolbox that's also workbench, angle-cut rig, electric strip, moon lander and, why not, just a backpack you can use to carry fragile stuff like optical gear.

Enjoy!

Step 1: Prototype Design

This must be the first time I went through a protype design before starting to build.
I just wanted to know what the scetches I made would look like for real, and so I made a version in cardboard & styrofoam.

Generally I was quite pleased with the concept, but one thing that made me laugh in the first place & worry in the second was that it looked terribly like a coffin. Or even worse, a small coffin.

No-one would like to walk the streets with a mini coffin on its back. A full size one might be funny, but this was everything but full sized.

So my design needed to be 'uncoffinized', and also I decided to give it a bit more height.

I decided to build it almost entirely with alubond - a composite material I already used in previous I'bles. It's not cheap - some 150$ per square meter (I got the chance to have some leftovers for free). But it's relatively light, cutable with the miter saw and easy to rivet.

Step 2: Inner Structure

I decided to make a solid inner structure, since I'm used to use my toolboxes as a handy step (that's how I crushed the toolbox of a collegue, once). Too bad he had hidden his sandwich in that box, too.
Could have been worse after all. He's the proud owner of a chihuahau.

Plywood (16mm thick) looked okay to me (a bit less would haven been okay also), so after the shape of the ground plate I started to shape the three panels of the skeleton.

Note the angled edges. A miter saw is really a must. Set the right angles and rock those cuts.

Screwglue them together and screw the skeleton to the ground plate. Inox screws. High performance pistol glue.

If you want a nice finish you can cut some alubond panels and glue them to the inside of the box. Needless luxury maybe, and more weight to carry. That's why I did it.

Note the extra's at the top of the verticals. Those'll serve to insert magnets later.

Step 3: Outer Plating - Fixed Parts

Put your work upside down on a piece of solid plywood and mark the four corners to create the plywood cover.
Cut it out with a miter saw and respect the angles of the sides!
Screwglue it in place.

Then measure carefully the four corners, cut the four triangles and screw them to the inner structure.
Countersink the screws.
Use aluminium tubes to rivet those triangles to the ground plate.

Step 4: Outer Plating - Movable Parts

Time to make the doors.
Again: measuring & cutting.

A nice way to make hinges is to use inner tubes.
Glue them them to the ground plate and door panels with double sided tape and use alu strips to rivet the whole.

Cut the excess of the panels and use magnets to keep the doors in closed.

Step 5: Hammering the Cover

This alu cover has two functions: as slip-proof step and a closure to keep the four doors closed when the yak is on the move.

To cut this cover right you should make a copy of the wooden cover, and place it on a piece of antislip alu sheet. This piece will serve as mold when you start smashing the sides.
You can use the original piece, also. But hammering implicates impacts, and unless you want to destroy your box it's better to use a copy of the plywood cover...

Mark the four corners and cut the four triangles where the sides will meet. A bit of calculation, I agree. Or do it 'at sight and good luck' like me...

Clamp sheet & plywood and start hammering the sides.

Cut the excess at the end and smooth those sharp edges.
Did you know you can easily cut this stuff with a jigsaw? Well, now you do.
Use ear protection, it's a kinda loud operation.

Step 6: Finishing

I used a few pieces of riveted kydex (or similar) to have a nice finish on the rather uggly corner panels.

Call it 'the cool factor'.

Needless luxury, again. So do it anyway.

Step 7: Carrying Gear & Stabilizers

Now the 'box-part' is ready we're gonna make it a backpack.

For that we need lanyards & a back protection.

Use some nice belt stuff and transform it. Instructions in the pics.

Note the 'stabilisers'. The rubber dots hold the box stable when put on the ground. The lower are fixed, the upper are removable. There's only one on the pic, two will make it more stable.

Step 8: Extra 1: Electric Strip

It happens often when I'm on a worksite that I need an electric extension or a strip. So why not integrate this in the box?

Another reason: no-one could steal this object anymore!

Step 9: Extra 2: Drill Storage

How a simple hole can make the difference between carrying your drill with you, or not.

Step 10: Extra 3: Angle Saw Rig

Another habit of mine: using my toolbox as support to cut angles on wooden, alu or plastic profiles.

Instead of carrying a miter saw or a classic U-shaped wooden rig I made this cool piece to ease my worklife.

Concept: fix a removable 'saw-guide' in the cover of the box and combine this with another piece of plywood fixed temporarly to the cover.
Set the right angle, screw the guide, slide the profile and cut.
Remove & store after use.

Step 11: Painting

Yes, this needed a lot more creativity...

I should ask one of our local graffity artits to pimp this up!

Step 12: Storing

This box is definitely large enough to carry my essentials: drill, saws, a lot of hand tools, silicone or glue pistol and some small hardware - enough to do half of what clients ask me to do.

Don't forget: I still have both hands free to carry other gear.

Wanna use it as a classic backpack? Easy, even a telescope & binoculars can go inside and be transported in all safety!

I'm sure there are plenty more possibilities for this device. It can be a portable kitchen, gamers box or boozebox - got to try this ;)

Suggestions? I like to know!

Hope you like it as much as I do. If you have any questions, comment below!

Step 13: Evaluation

There's a lot of good to say about this prototype, but it wouldn't be correct not to talk about its inconvenients.

First of all: it could have been less heavy. It's okay to me, even filled with gear, but when my wife tried it, all she said was 'you're nuts'.
So if you want to keep it a bit lighter I can suggest:
- to use plywood of 10mm instead of 16
- to drill a few holes in the inner structure with a clock drill - it will withstand someone standing on the box anyway
- not to glue extra plates on the inside of the plywood (step 2)
- to use less rivets & screws, maybe

Second, it's not yet watertight. So I suggest or to add rubber joints at the inside of the doors, or to use a backpack poncho when it's raining.

Third: the magnets to hold the doors closed aren't sufficient, so I added an additional groove&slot-system to avoid that the intestines come out of the belly every time I'm removing the cover.

Fourth: yet to discover. Check the updates!

Step 14: Training Day

27 march 2014 - First Trial

Weight Backbox One: 24 Kgs - 52 Lbs
Weight bellybag: 9 Kgs - 20 Lbs

Let's call this 'full capacity'...

Distance to worksite: 3km - 2 miles

One word: it was awesome and even more comfortable than I thought.
I'm sure this device is gonna give me a lot of pleasure the coming years!

Yak-proof, definitely!

The only inconvenient of the day: I wish I had integrated a toilet...
<p>Thats totally awesome man! id like to make one out of aluminum tread plate because i know how to tig weld! cool beans man cheers!</p>
<p>All right. As another nomadic handyman, I think this is absolutely brilliant. I have a single advantage/disadvantage in that I ride my bicycle to my sites. I will have to SketchUp this pack for use on a bicycle. I'd use saddle bags for the front weight, leaving my back for the bigger bulk. and then there is the balance while riding. I'd look like someone out of Mad Max but I'd have all the tools I need. I might have to add slots for carpenter's squares on the outside. You've inspired me mate.</p>
<p>Driving in rural Indiana a few years back, I saw a carpenters work &quot;trailer&quot; pulled behind a motorcycle. It was small, maybe an upgraded BoB trailer which is a much better way to go than paniers for the bicycle carpenter. I wish I had been able to snap a photo of the motorcyle trailer it was brilliant.</p>
<p>Thanx my friend, I'm pretty sure the bike-version will look very cool! Do you think you'll have to upgrade the tires, or do you have a sturdy postman's bike?</p>
<p>Nice pack. I was thinking of making something similar for a while now <br>to carry my electronics diagnostic/repair/hack/rapid-prototyping stuff, but an ordinary backpack does <br>not fail miserably for this task as of now, so.. I dunno. Maybe, one of <br>these days...</p>
<p>Congratulations on your winning my friend :). Great show :)</p>
<p>Thanx future winner of the jewelry contest ;) - I'm glad I made this, thanx to this device my daily work is become even more pleasant! ;)</p>
<p>Thank you Fortune Teller Friend :), oooh that prize is awesome :)</p>
<p>that's awesome :)</p>
<p>Thanx mate!</p>
Gotta do this for my costume of a Warhammer 40k Techpriest. Could be used to carry miniatures for my army too
<p>Thanx mate, you won't regret it!</p>
<p>Very cool. </p>
<p>Thanx!</p>
<p>First off: awesome! Great instructable, and even better project!</p><p>This pack would be perfect for ice fishing. I'm guessing you're not very familiar (Belgium is a little too mild), so I'll explain a little. #1 issue with packing for any ice fishing trip is rod storage. They always seem to get smashed, bent, or tangled up in other rods. I've been devising for years how to make it work. A few years ago, I took an old army issue pack and put a 4 gallon square bucket inside. It's my best solution yet, but has a critical flaw. #2 issue: seating. Buckets are the standard in ice fishing furniture, and by packing my bucket away, I lose my chair. What you've made here is the perfect compromise. This pack is essentially a stool. Sell this to <a href="https://frabill.com/" rel="nofollow">Frabill</a>, you'll make a mint.</p><p>Great work!</p>
<p>Stop making me dream to move to North America, you're just creating war between my wife &amp; me - the dog's got no problem with it ;)</p><p>Thanx for the great comment - I don't blame you that much for calling this a 'stool' ;) - and no, the last time we could do some ice-fishing in Belgium was during the last ice-age... I tried it once in Finland but didn't catch anything. Hope you'll try this out, and looking forward to the result!</p>
<p>You could have advertising on the outside. &quot;Handyman&quot;&hellip; why not use the space to get more clients?</p>
<p>THAT'S what I call a great idea! Using stickers is an option, or ordering custom aluminiun plates (like car registration plates) riveted on the sides!</p><p>You just added the 'hot-factor', congrats ;)</p>
<p>Thank you for the innertube hinge idea. The power extension is perfect. I love your miter replacement concept. Excellent project!</p><p>The phrase &quot;comma error&quot; for the price of the retail version made my American number-parser translate to quite a large number. Which may only be a slight exaggeration anyway. :-)</p><p>I might just have to follow in your footsteps on this. Though my toolset lacks the sharps, being primarily tech, it also lacks a certain amount of durability that existing in a soft backpack occasionally causes me worry.</p><p>I've dabbled with thoughts of including a chair function in my pack, though chair+worksurface might be both more useful and much harder to do, so I guess I should do that, right? :-)</p><p>Thanks for the ideas! Great work!</p>
<p>Thanx for that nice comment Alderin! Actually, you CAN use it as a chair and it's quite comfortable though! For that comma issue, hum, the bagpack I found costs about 260 euro - 360$... Right, 36$ would have been a bit too low, but those prices are high above my budget...</p>
I'm sure it is an excellent short-term chair, but if you have to spend three hours digging into a problem requiring more brainpower than you can supply while standing, a comfortable chair with a back and arms is very handy.<br><br>Yeah, in the US commas are only used in numbers over 1000 to designate thousands, millions, etc. &quot;$1,000.00&quot; so a comma error in a price means... WAY outside of a budget I'd consider for a backpack. At least if speaking of Euros or &quot;Dollars&quot; (various local dollars, USD, CAD, AUD).<br><br>I agree that 260/360 is high enough that I'd go for building my own. The decision is balancing the price against how hard/fun it would be to build myself. A $50 hard pack would push that balance toward purchase for me, $100 would lean more toward built it, and anything higher is: just build it.
<p>In fact, I never noticed there was a difference between the comma and the point in US numbers. Maybe it's even the same in Europe - how stupid I feel right now...</p><p>Whatever, I agree with your upper-limit: 50$ seems fair to make it yourself or not ;) Feel free to modify backbox one into a comfortable whisky savouring device and have a nice weekend over there!</p>
<p>have you seen this</p><p><a href="https://www.instructables.com/id/wheelchair-workstation/" rel="nofollow">https://www.instructables.com/id/wheelchair-worksta...</a></p><p>I like the wheel chair idea, it has large wheels for rough trails, and will fit in an elevator.<br></p><p>also this?</p><p><a href="https://www.instructables.com/id/The-Smallest-Workshop-in-the-World/" rel="nofollow">https://www.instructables.com/id/The-Smallest-Works...</a></p><p>or</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/cT5fE6HEMWs" width="500"></iframe></p><p>here is what i did to my ATV</p>
<p>Interesting design, that ATV. You should make an Instructable of it, this could be a winner. Definitely.</p>
<p>the only change i made is to move the stuff from right side to left side. thus i can hold a ladder on the left and use the throttle with the right hand.</p>
<p>Not to TC or anything, but I probably would have started with a lidded 5 gallon bucket (lighter, waterproof &amp; potential toilet) and modified it to make it backpackable. Nice work on the Instuctable, but I'd definitely want something much lighter and less work to contsruct.</p>
<p>Nice idea, that gallon! The point is that I don't see me arriving at a client with a gallon on my back. Got to keep a few standards high! ;)</p>
<p>I bet something like this would fly: http://s.stpost.com/eccstorefront/product_images/5202m/f_5202m_1.1.jpg</p>
any thoughts on incorporating a hip strap?
<p>Indeed, it would be a good improvement. But till now I don't feel any pain in my back or shoulders, it's really a lot more comfortable than it looks like. Really!</p>
I was at work today and played around with some extruded aluminum laying around and may have come up with a light weight frame with the strength of 300 lbs capacity possibility. Along with a couple ideas of my own and when the little one lrts me have time....... I will build and attempt another ible and let ya know when its done.
<p>Lookin' forward to it mate!</p>
<p>a whole lot of thought went into this package.</p>
<p>;)</p>
<p>To make the carrying easier, locate an old tramping pack with a separate frame. This will have all the straps and waistband you need to carry in comfort.</p><p>The packing can have a huge effect on the balance, heavier things low and lighter things high, as well as equal left and right.</p>
<p>You know, it's a toolbox. It's built to store a hell of a lot metal in the right half, and the same hell in the left half. When it's full, it's balanced, believe me ;)</p><p>I thought about adding a waistband too, it's an idea that deserves a chance!</p>
<p>This is a good idea. Would it be lighter to construct the frame from angle iron instead of plywood? The aluminum panels could still be riveted onto it and making it water proof would be easier.</p>
<p>Interesting idea, but don't you think that the weight of al those sturdy alu-profiles will be equivalent to the plywood? And will it be as sturdy as a whole?</p>
<p>This is pretty cool. I wonder if you could trim weight with a 2.0 version made from carbon fiber and fiberglass frame construction. <br><br>And never say no to a Beer, indeed. +1</p>
<p>It would be lighter, indeed, but I think you can multiply the cost. Feel free to give it a try! ;)</p>
definately making one of these this summer. Awesome!
<p>Thanx, good luck friend!</p>
<p>Sweet. Gonna have to build me one now. As a part time blacksmith this would be useful for lugging all my demo crap around and I could probably make it look 1800's ish if I put some work into it.<br><br>I might consider putting some bungee cords inside to keep things more stable. Maybe 2 or 3 in front of each door to keep things from exploding when opened, and a couple on the divider wall to secure the heavy things I don't want to shift as a 20lb mini-sledge shifting suddenly can really screw with your balance.<br></p><p>Also I'm curious on how well the plywood is holding up to the areas where you are always screwing and unscrewing components (like that sweet miter rig). How many times do you think you'll get before she gives up the ghost. I might rock more the slit pin and wedge combo than wood screws but that is because while you always have a drill I nearby always have a hammer at hand (and it would keep with the period look).<br><br>If I were to go 180 degrees away from &quot;a period look&quot; and make a booze and boom box It would be interesting to do all the support structures in something like DIY foam cored carbon fiber to drastically reduce weight and increase strength... but at 10X cost. Still if it meant the wife could drag it around instead of me it might be worth the investment. </p>
<p>I'd like to see your backbox version mate - and for a blacksmith it'd better be totally different! For that plywood issue: since that big 'kork' aka guide I made is mounted on a metal plate (see pics) I have to compensate the height by adding something like a piece of alubond to cut those profiles till the end - preventing I'm cutting my box. So, no worries about that. Lookin' forward to your project!</p>
pretty cool idea. very entertaining. like chris, there are times i need gear and a step, work alone in high places, would make for easier carry and less rigging. would tie off my gear bag on my harness climb and get tangled up.
<p>Thanx mate. I know this is a kind of 'niche project' that won't be useful to anybody, but for those in need it's a real musthave. Hope you'll give it a try, good luck!</p>
<p> Great ible, but i wanted to know , its a bit of a personal question but what is your day job ?</p>
<p>Well, I'm working as a 'professional McGyver'. I repair stuff all day, going from broken flushes over rubbing doors to kitchens that have to be entirely renewed. Plenty of variation, being my own boss, satisfied with what I'm doing (most of the time) ;)</p>
<p>Very Cool Superhero Toolbox!</p>
<p>Thanx mate!</p>
