I'm planning to get HF's Micro Mill.
The one critical job it will be doing is finishing one or more 60% 1911 frames.
The mill comes with a Jacobs style chuck.
Is this sufficient to run the small (.050) end mill I'll be using to cut the rails,
assuming light passes and fairly slow feeds?
I plan to cut them undersize and open them up with a rail file anyway.
I don't want to bother with collets and a drawbar right now if I don't need to.
Any experience with this?
