100 mW
I would like to cut a 100mm bottom bracket down to around 72mm so that I could use a 68-73 BBSHD that I own. Also it would allow for a more precise Chainline. And no, I dont plan on converting the bike back.
I've looked for posts by others that might have cut down a bottom bracket, but my searches return no results.
I don't have any special tools to do this. So I was thinking that first I would scribe each end of the BB as precisely as possible. Then I was thinking it would be good to put a hose-clamp on the end of the BB as a guide and then using a hacksaw and then cutting the BB as best I can.
I do know a friend that owns welding fabrication shop. And was planning on running my procedure past him. But maybe he might have a better way to best cut the BB down in size with specialised tools.
I should note that cutting the BB down to 72mm would mean cutting right to the edge of existing welds where an oval tube that connects the BB to chainstays (it's an Electra cruiser).
Ideas anyone?
