Trying to Quieten the 110KVA Generator
awemawson:
The plan (when I can escape from Puppy - double cottage change over today so a bit hectic here :bugeye:) Is to remove the tail stock from my 40" Colchester Master, fit the Fixed steady down the tail stock end, and gripping the collar in the chuck carefully turn off the weld. This is only going to work if the collar is reasonably concentric.
Depending on how good the penetration is I may not have to go much deeper than the minor thread diameter but it all needs a good rotary wire brushing before it goes near my nice lathe !
djc:
I must have missed it somewhere, but why does the joiner need to come off at all?
It is possible to buy a street elbow to go in its female thread or a close nipple to convert it back to male thread for a standard elbow.
Even if unthreaded or damaged threads, could you turn the threads off one end of a close or standard nipple and use 6013 or 7018 loctite to secure it in the joiner?

The pipe would be too far off the wall, and the coupler thread is not very good and not even round at the exposed end :(
Anyway things have moved on - managed to escape for an hour this afternoon (guests running late :thumbup:) so removed the lathe tail stock and mounted up the pipe, coupler in the chuck.
Initially I turned the pipe up to the shoulder down to the minor thread diameter, then about 50 thou below, and even tried to undercut the shoulder but it wasn't having it, the weld penetration must have been good!
So I decided to part it off, and see if the remaining thread would work with the elbow (It's a BSPT thread so tapered)
Sadly not - I can get about half a turn on. So I decided to mount it up and re-thread it on the lathe. Carriage to extreme right which involved removing the taper turner bracket and RH stop mechanism but still I couldn't get the threading tool far enough to the right.
Now I must study pictures, but I think the I can shorten the pipe at least 1" maybe 1.5" which will solve the problem, but time caught up with me and I had to go 'meeting and greeting' !
. . . .so hopefully a job for tomorrow

Turn the tool end for end and mount it on the other side of the tool post .
