I'm taking some machining courses and we have get to pick a simple project we need to program onto a CNC lathe. I thought i might as well make something useful, like a head button. I've seen some pictures of the button i plan to make, for a Hawk Pro, but i would need dimensions or more detail of the threads. The actual head shape or dimensions don't matter much, i can be creative...

I understand the threads are counter clockwise, so that when you use it to stop the head it tightens. Its a plastis head block and there are no threads on it... I just figured maybe Century did some tests and found the idea threads to use.

Anyone got one to measure, or know otherwise the size i'm looking for?
