Have a look at Projects by Mr Pete. you will find dwg. for several project that others like I have made for free. I will see if I can attach one of his dwg. that I have made to this post.I am looking for simple projects for apprentices to make. No welding, only Cutting, milling, and lathe work, please. Vises, Pens, and the like.
The vise will attach to a workbench. The pens can be made of steel, iron, aluminum, or brass and use standard link refills.
