My drawings and measurements are metric, so if you use imperial measurements (and correspondingly buy materials in imperial) you'll have to tweak and possibly redo the drawing/measurements to suit your needs. Also, my numbers are a bit wacky (for example, the drum is 1152mm in diameter rather than my intended 1.2m). Many of these odd numbers are a result of mistakes I made during my process. I wanted to learn, and so I didmaking many mistakes along the way. As wacky as some numbers are here, I have used them in this instructable because I know for a physically-constructed fact that they work. And as to the pictures, I did the project nearly two years ago now; I took pictures for what I could--planning for an instructable eventually--but was sometimes too caught up in building and learning for pictures. But that's the point, right?
A final warning: this project isn't super low-waste (mostly for plywood), nor is it super low cost (assuming you have access to all the tools, it's about $300 to buy all the materials/fastners/paints). You will, however, end up with a bizarre and unique piece of furniture that tells well your skills and obsessions.
Skills/tools: In this project, you will [learn to] weld steel, plane wood, staple-gun fabric, paint with a very viscous paint, cut fabric, cut wood, cut and de-burr metal, sew stretchy and non-stretchy fabrics, drill metal and wood, use a router to plunge-cut and to edge, sand, and glue. Though not in that order. It's a lot of skills (and access to a lot of tools), and definitely a good project to learn a wide range. That said: IF YOU HAVE NOT BEEN PROPERLY TRAINED IN ANYTHING EVEN REMOTELY DANGEROUS IN THIS PROJECT, PLEASE ONLY DO SO WITH SOMEONE EXPERIENCED WHO CAN TEACH YOU PROPERLY. Wear safety glasses when appropriate (i.e. all the time) and hearing protection when using loud cutting tools, fume protection while painting, and all kinds of protection while welding. Be safe, build well, learn much, and have fun!
