Re: Grizzly mini mill

Which taper are you referring to? The machine spindle taper should
be R-8. And you should have an R8 chuck holder with either a female
#(0,1,2) Morse or a male Jacobs (3, 4, 5, 6, 33...). You could have a
morse with a drawbar, but I think that would be rare on a new machine.
The R8 requires you loosen the drawber ever so slightly and give a
sharp rap to release. The J taper requires a yoke type key and can be
very stubborn. The Morse is as you described.
Have you resolved the problem?
