Bike Tire and Gear Belt

Step 9 Weld crossbar onto small gear

I made a crossbar out of a 1/4" bolt.

- cut the ends off the bolt until it is the right length.

- clamp onto the gear

- weld the ends onto the gear

Hey, I'm doing someting like this but I have no welder, haven't found a strong enough epoxy or glue yet, and solder didn't take

Did you have to use a lower setting for this? My dad's got a welder so that's fine, but I don't know how the gear would stand up to heat.

 or if you have the ability to, get a hold of a TIG welder, that would be my choice, just make sure to grind the galvanized plating off of the bolt though, or you could get poisoned

Yeah we have a gas mask for that exact reason. I took apart a rear cluster and made an Instructable, check here: www.instructables.com/id/Taking-apart-a-bikes-rear-cluster/

 haha yeah, i saw that when i first saw this, much better than the method here IMHO, plus, i'm using the sprockets for a double kick pedal for drums, and a few more for an EV I've been wanting to build (likely a motorcycle), so i would rather have them flawlessly disassembled :D

[MrRodrigez]

 try running your welder at around 90 amps or so, and adjust the wirefeed to whatever you can handle, i weld some pretty thin steel at about 60 amps, so 90 should be just fine

I think for this part you may be able to use a couple of spokes instead and possibly braze them instead of welding. I'll build a belt and let you know how it works.
