Freezing and # of cuts Posted by Ari [Email] ![]() ![]() In Reply to: Re: Dogbone bushing...., Shawn, Wed, 22 Oct 2003 10:32:31 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I've seen tht freezing trick used for bearing installations, and other force-fits in industry. It also comes from the old days when they installed metal rims onto wagon wheels. They would heat up the metal rim in a fire, then drop it onto the wheel and douse it with water. The rim would contract and make a nice force fit.
I did two cuts, because I was using a jeweler's saw, and the blade has a *very* small kerf- only about 13 thousandths. That doesn't give enough of a gap to ease the forces enough to slide the bushing out. A fatter blade would give a bigger kerf. However, a jeweler's saw with a nice, sharp blade cuts very fast, and fits nicely. No big deal, whatever works, and I'll bet most folks don't have jewelry making tools lying around.
