The thumb in suspender expertise on this thread is hilarious. I work in a pump/motor rewind shop that specializes in submersible pumps, and, except a short 3yr stint in a jydraulic shop, have for 10+yrs.
Rust on the laminations is no huge deal. Hit it with emory tape on the lathe to keep the...
You're going to have to go old school and figure this the hard way. Measure the leadscrew pitch and then figure what gear combination is going to make up 20tpi. Good luck. Looks as bad as the Summit here at work that changes thread pitch with speed range. Slowest you can cut 20tpi is 250rpm on...
The far-easters, in their infinte wisdom, put an open ended fan cooled motor on my unmentionable brand 9x20. The fan slots set almost exactly in line with the chuck on the back side. After taking it apart a few times to get chips out, I got a metal coffee can, punched a bunch of 1/4" holes in...
In the aviation world, common method on floats was to use a two part flexible fuel tank sealer compound... sort of a cross between an RTV and an epoxy. Can't remember the brand name. Was 20yrs ago now, and the guys are all gone.
Agree with both the above, I'll also add that some of the old books say to only chip with a chisel or file for prep, grinding smears graphite. Get a can of powdered flux (you can occasionally catch it at Tractor Supply) to flux hell out of the joint. Restaurant type salt shaker works great for...
Nope, a 20mm tap has a 15mm shank. It will not go in a 3/4" driver. I have most every tap driver over 1/2" and nothing fit the 20mm. A 19mm tap fits a 3/4 and a 22mm fits a 7/8".
Any of the typical degreasing products contain sodium hydroxide (lye), which is very corrosive to alumimum. About the equivalent of saltwater to steel. Switch to a simple soap and water cleaning and isopropyl alcohol. Should eliminate the problem.
Another option to make a pattern lathe work better is live tooling on the carriage. Helped a friend repair some VERY coarse threaded wood table legs. We tried a razor sharp thread cutter in my old L&S, but it still just tore out the material, especially on the last passes. We ended up using a...
