The Modular Lathe Jig was designed to give the lampworker control over how many tools they want to position relative to the chuck center, and the distances between tooling placements. It consists of a rail and tooling blocks. You may specify the length of rail needed for your application. You can fix as many tooling blocks as will fit on your rail. Each tooling block can hold rod OR tubing up to 12.7mm. Because of the modular design, configuration possibilities are endless!
