Spindle thread protector

[Shawn]

This is something I have been wanting to build for awhile. It only took a few hours, most of that was boring out the hole in the hot rolled bar. Man the skin on that stuff is tough, once through that though, it machined pretty nicely. I started this project yesterday but had to scrap it when I discovered the internal threading bar I bought had a brazed tip with a totally wonky grind? It was no where near 60 degrees and the resulting threads were a really bad fit. I made my own and it worked much better.







Good practice for the ER32 spindle chuck I will build next.
