In this video we are driving with a #7 carbide stub drill, chamfering with a 3/8" carbide changed mill and thread milling 1/4-20 holes with a single point 1/4" thread mill, all tools are from http://onlinecarbide.com/ which offers excellent tooling at an affordable price! We are performing the operations on the mini lathe cross slide to mount the new tool post riser!
This was a fun project to upgrade the tool post and compound of a little h harbor freight 7x10 mini lathe I snagged on Craig's list for $100. When purchased it was missing the change gear, reverse Chuck Jaws, tools and a few other minor components. However this was fine for my application because this little lathe is slated for a CNC conversion and some chassis upgrades to stiffen up the movements to cut small parts in stainless steel for business. Should be a great value for second operations that doesn't take up any more space than a tool box in the shop!
Follow along as the little projects come together to become a working machine! Hope you enjoyed this build!
