Well, the one thing missing on my New lathe is a solid carriage stop, so I designed one in CAD!
First I had to reverse engineer the dimensions from the lathe so the clamping mechanism would work, and the position of the adjustable stop screws would not interfere with any other part of the lathe!
I decided on a five position indexing turret, which uses 5/16-24 UNF threaded screws!
When the CAD work was finished, I called Speedy Metals and ordered a 4"x4"x4" cube of solid grade-40 Cast Iron, along with a 2" dia x 3" long piece of 1018 steel, and a 3-foot piece of 5/16-24 threaded rod from McMaster Carr!
The Cast Iron cube cost me $30.63
