The next band saw challenge is to make probably the most complex and intimidating parts on a homemade machine, the wheel. It has to be:
- precise and a 3D printer can do that easily
- balanced which is hard to do with wood (but easy with 3D printing)
- have a slight crown on the rim to make the blade track properly. Again easy to design in with a 3D printed wheel, but difficult to do when making it from wood
- strong and that was the question I answered in this video. The 3D printed wheel is absolutely strong enough even when left under tension for an extended period.
I printed the wheel in 10 pieces - 8 wheel segments and two hubs that took almost 20 hours to print.
The mistake I made that caused the wheel to wobble was having too much clearance around the alignment pins that fit into the holes in the wheel. A better way would be to either make it a tighter fit or make it so that it can be adjusted, i.e. bolted together rather than glued.
But wobble haw no effect on performance so a small amount is perfectly fine.
