I have used this mandrel for turning salt shaker pepper grinders for awhile now. Its about 10 and 1/2 inches in length has 3/8-16 left hand threads the whole length except for a little bit at the tail stock end for the mandrel saver to slide over and about 3/4 inch at the head stock end where it's threaded 5/16-18 right hand threads to screw into the Morse taper that it came with. The threads are getting pretty beat up and I'd like to replace it but, for the life of me I cannot remember where I got the thing. It came with 3 sets of rubber bushings and some left hand nuts that allow you to expand the bushings inside the what ever you're turning (in my case the salt shaker pepper grinder kits from Penn Sate Industries) to hold them for turning the profile you want.
I have searched the internet and looked at all the turning tool sites that I have saved but, I cannot find it online. Does anyone have one like it that could direct me in the right direction to get a new one? If not, I'm going to have to make one myself. Was just hoping to save the trouble and keep turning things I want to work on.
Thank you in advance.
