Bill Marvel’s Spindle Lock
Bill Marvel says, "Over the years I occasionally have seen the need for some sort of spindle lock. I have seen several ideas but they were far more complicated than I needed. Cutting threads with a Taig die holder in the tailstock is one of those times, especially if you are threading a hard alloy. I don't seem to have quite enough hands to hold the pulley (or spindle wrench), put some positive pressure on the work and turn the die holder with a tommy bar. So, I took a length of 1/2" square aluminum rod and drilled some mounting holes for the headstock. I centered a cross hole and tapped it for 10-32. I drilled a hole in one of my steel spindle wrenches. It ain't pretty but it is very functional. Easy to mount, remove and store.
