I'm building a hard drive based spinner. I found a perfect knob off of an old exercise bike. It has a 1/4" shaft hole with a bolt to hold shaft in place.
I took apart and old 1.2 gb Westerdigital IDE Hard drive. I am using the bearing from it.. The hole on the top of the bearing, seems to take a 2mm screw.
So my question is where can I find something that has a 2mm screws . Maybe if I found a long 2mm screw I could put 1/4" spacer on it. I check home depot and radioshack but no luck. I will be hitting the smaller electrical shops in town.
Any Ideas,
