People were looking for a way to connect 1" x 8 TPI accessories to a Shopsmith lathe. The few solutions available from China and I heard some while cheap had real quality issue. I found a better solution, I called http://bestwoodtools.com/ and spoke to a wonderful lady from Tennessee. They sell all kinds of adapters for lathes and she said they would be happy to provide one for the Shopsmith that goes from 5/8" plain to 1" x 8 TPI. Normally their adapters sell for $59.99 but for the Shopsmith they are $49.99 made in USA.
They also sell excellent lathe tool rests out of hardened steel that fit the old Shopsmith 3/4" hole, I asked and she said they would also make one for the newer 1" hole on the universal tool rest banjo they just need to get the correct length. It is a modular system so you only need one post and can put on lots of tool rests up to 12" long and they have other things that fit the post as well.
