I’m still working on the wheels.
Now they’re round and crowned.
Also I’ve formed the drive pulley.
I tore apart two old treadmills, and used one as a temporary motor to spin the wheel while shaping it. I have what will probably be the final motor on the bandsaw, but I used the treadmill motor for its variable speed. I kept it fairly slow since I have zero wood turning experience.
It took awhile to get the wheels round, but I think they turned out alright.
Next steps are to put some finish on the wheels, attempt to balance them, then apply the bicycle innertube tires.
