I cut through the aluminum. 8" of 3/8" aluminum with a dull hack saw, that was fun
And below, you see the n00bish results of my handiwork. Along with a prototype sandwich plate on the other side, made of wood, just to get the hole spacing down. The bolts on either side of the tube aren't installed in the picture, it's being held on by two bolts through the tube. I need more bolts
Any opinions on what I've done so far are appreciated!
Hopefully you can see my hacked-together chain tensioning system for the small chain. It better hold up
. As far as chains go, I've been informed that my hacked #40 sprocket needs work. I agree
But still, I lack the skills/tools to make one that I'm truly comfortable using regularly. So I'm wondering. Does anyone have any idea how I can get a 11-or-so-tooth bike chain sprocket onto a .5" shaft? I'm open for any ideas, even for having someone machine another #40 sprocket for me. however, I want to keep it under $25 if I can, and with that budget I think machining is out
PS. My freewheel finally got here, guess what, it doesn't clear my bottom bracket. Luckily, I anticipated this problem and bought a 158mm spindle to replace my short one with! Unluckily, I assumed that if you could buy replacement spindles, its possible to replace your spindle, which it apparently isn't. Also, 158mm is really way too long. So it looks like I'll be spending another $25 on a SBP bottom bracket and a few more $ to get the current one replaced. Oh well!
