I understand that anyone with the Red Coronet Major struggles with headstock fittings as the thread is an obsolete 7/8” 16Tpi.
Having one of these myself and having just started to use the lathe I thought I would source an insert that would allow the use of more modern chucks etc. I did post this on the end of another thread but not sure anyone picked up on it.
I’ve got a price from a local engineers to CNC machine a insert with a 7/8" 16Tpi internal thread and M33 3.5 external thread.
Prices are:-
1 off threaded insert @ 70.00
5 off threaded insert @ 30.00
10 off threaded insert @ 23.00
If anyone is interested please let me know and we could make a bulk purchase and get a good deal .
I’ve added a rough sketch of what I have asked them to price up.
I live in Sale Cheshire and would be willing to post to anyone who would like one.
Cheers SMcK
PS. I hope this doesn’t break any forum rules.

Well eventually got my insert made and it turned out I knew the guy at the engineers I had been emailing for prices so got a good deal on that. My insert gave me a M33 3.5 thread so I went looking for a chuck and I found a Record Power SC3 at Elmers hardware for £99 delivered. Its a nice feeling chuck and good value I believe and it all fits on my lathe perfect. Just need to get turning now. Bit cold out in the garage yet.
