Thread adapter for union graduate 1.5" x 6tpi

[jonas]

I have recently purchased a union graduate lathe & with it came a very nice axminster evolution chuck LH/RH with extra jaws plus a rather heavy 4 jaw "engineers" type chuck.
I have two oneway chucks 3/4" x 16tpi  with a variety of jaw options including button jaws which I would love to be able to use, but I have been unable to find a reducer.
 Can anyone out there help & make me a happy turner.
The oneway chucks have a "taperloc" type insert that can be changed for a variety of threads but the largest is 11/4"

Good morning Joanas
I had a similar question at the end of last year from a guy called John, there is a shop called Covacs in Ellistown Leicestershire who are able to make them, I'm unsure of what the cost was but for comparison I had a LH Thread for my compound mitre saw made as I couldn't get one anywhere and they charged me £10 to make 2 (I wanted a spare lol).
Please let me know if I'm able to assist you further.
Kindest Regards
Ryan

I use a Union graduate lathe with Axminster chucks(not Evolution) and Oneway chucks. I have 3 thread sizwz to contend with, 1 1/4" x6, 1"x8 and 3/4" x 16 and I managed to get thread adaptors for all of them from Axminster power tools. Talk to their technical department.

John
I contacted Sam Turner "Specialist Advisor" at Axminster only to be told that they do not sell a thread adapter for 1.5" x 6tpi. & could not help.
Thank you very much for your response

Ryan
Thanks for your help also. I will be contacting Covacs tomorrow after the Axminster disappointment. 

Thank you both once again for taking the time to respond.

Kind regards

Look good Ian, the one you made me works a treat 

[The Bowler Hatted Turner]

Ian I do not wish to criticise and it may be unfounded(in which case please accept my sincere apologies) but the register face on the LH adaptor appears to have a step in it, these faces must meet true and flat and tight or you will get chuck wobble, I expect you know that. but just in case.....

[Ianparkin]

I think its just a trick of the light the face for register is flat and true
I've been making adapters for years for my graduates and others machines

I thought that would be the case but as the H&S man I thought I would check anyway. Apologies.
