Hey. I think I am going to order the threaded section and turn down one end and bore the other for the splice. There are a couple different variations of acme precision all thread. This seems to be the place to get it.

What item number is a match to the value master series you have 4gsr? I just want to make sure I get the right one. Also any tips to turning down one end of the hardended all thread? Also I'm thinking of making a simple aluminum collet to hold the thread rod while lathe operations take place as to not mar the threads. Any tips would be appreciated.
Thanks
