Nice machine 10/4/2017

You know when you picked the right company by the costumer service, I had shipping damage thanks to ups gorillas. Grizzly took care of the problem (thanks Steve) right away. Well made machine, it cut. with in .001 in 2 feet and repeated on the dial . The threading is perfect, I cut 1/2×28 threads for a muzzle brake came out great. The mill is very basic but solid and works good. Overall great machine well worth the money

This is it. 12/23/2015

I've had mine since summer of 15'. It is very similar to the Harrison Engine Lathe I ran years ago. It is about 1/4 the size of the one I ran. I have only wonderful things to say about it. Wiring was no problem. I haven't seen anything to complain about other than, I had to buy an Engine hoist to assemble it. Now I have 2 ton crane. It is a beatutiful machine.
