    Some things are very well made others are not, they are very lax on finishing threads on parts they are extremely rough.

    Great Lathe
    5/ 5stars

    I purchased this machine after months of research. I decided to place my order with Grizzly because of their great customer service and they are a big well established dealer. The lathe arrived in a very large well-made crate with no shipping damage. Set up and cleaning all the rust preventer compound took several hours but was not difficult. The Apron gear box was already filled with oil but the head stock gearbox needed to be filled with 3.5qts of oil which I ordered from a local Mobil oil supply company. It is a light hydraulic oil which is generally available but took about a week to order in.

    I turned a 1 inch steel test cylinder without tailstock support to test that the bed was parallel to the head stock. The first pass showed less than .0002 difference over 12 inches. A very small shim near one of the lathe mounting bolts brought this to less than .0001, very hard to measure any smaller and more than acceptable for my purposes. A test cylinder turned between centers was dead on with no measurable difference over 12 inches. Remarkable performance right out of the box. Overall the fit and finish is very good with all slides and ways being properly adjusted.
