The initial offering of this will be complete plans to build your own Lever Operated Drawbar.

All Items can be made with the Tormach PCNC and a good engine lathe. A 1/4" keyway broach would be helpful.

Modification to the original motor base casting is needed. So access to a second milling machine is also needed or a new casting can be purchased from Tormach.

All engineering was done in Solid Edge and the file package will contain Drawing files of all parts in PDF , .dxf and .dft .

All assembly and sub-assembly drawings. With shop notes assembly instructions and bill of materials.

It is a fairly complex mechanism so a good mechanical understanding is needed as well as good machine skills. It is a good project and very rewarding when done. Not to mention the great improvement to an already great machine!
