[PROJECT] Mini Lathe Mods

[EdK]

Back on to the cross slide extension. I was getting binding of the lead screw when turning the hand-wheel and assumed it was because of the 3D printed parts. I tried modifying the 3D printed parts but no go. I then made the spacer out of aluminum and was dismayed to see that it was still binding. I had put a straight edge up to the threads on the extended lead screw and I couldn't discern any warpage. Frustrated I set the project aside for a while. Got back to it and did a few more experiments and finally concluded that the lead screw had to be bent so I set it up in the the mill vise with a v-block and I could clearly see the end wobbling. I put a dial indicator on the end and this is what I got.  

A new leadscrew is on its way.
