Well, I guess memory is playing tricks on me again. I remember looking very long and hard to find an R8 to Nova native thread adapter, but was frustrated that the closest I could come was R8 to 1×8 tpi. Now I cannot find it again. I can find R8 to other common thread, but not 1”!!! I decided that since (at the time) I had access to a CNC machine that could make the required R8 with male thread to fit Nova native I would go that route. So I was very lucky.

Most machine shops now have CNC capability and likely already have the program for R8 specs. It s trivial to add a 1×8 TPI stub to that program, so they can be very cost competitive. It s worth getting a quote from a shop you trust.

Thank you for your patience with my bad memory. Age is catching up to me. i ll keep looking.

I ve never made one before, but now I have the capability to do it manually. There has to be a centering cone somewhere and I don t have any specifications for that.

I’ve looked for one of those several times, but like you I haven’t found one. What I did find was an R8 to 4JT (#4 Jacobs Taper) adapter that looks promising for machining the 4JT part into 1” x 8tpi threads. The 4JT taper runs from 1.1240” to 1.0372” and is 1.66” long, so there should be plenty of meat on the end to cut the threads. One is $16.77 on Ebay right now. Item number 303115796158
