a long time ago when I started turning I built myself a bandsaw. You could buy plywood kits for 3-wheelers then but I made a 2-wheeler out of scrap. the wheels were plywood, the spine and wheel supports were steel, the frame was bed iron, the tyres were slices of lorry inner tube, the tension had to be put on with a lever, the pulley and motor I had spare, so it cost next to nothing and was fun to build.
It cut oak 12 inches thick and any size log that I could get on the table.
The two main problems it had were that it kept stalling under load, so I added a lever operated clutch, and I couldn't true the wheels well enough so it kept breaking blades (they went with a bang, though they just seemed to stop dead in the cut).
Eventually it all wore out and I was too busy to rebuild it, so got an Ebay startrite. now all the bits are back in the scrap!
