Grizzly G4003G - 12" x 36" Gunsmith's Lathe with Stand

Showroom Pickup
When we set out to design a professional gunsmith's lathe, our G0509G, we felt that we should also make a smaller starter lathe for aspiring hobby gunsmiths. Don't let the "smaller" size fool you - this is a serious metal lathe with many features that will allow you to turn and chamber barrels just like the bigger one. Plus, it's one heck of a metal cutting lathe. Check out all the interesting features on this puppy!

Erie, PA
A solid lathe. 12/31/2015

I have had this lathe since October and have done several small projects on it. It was a bit more difficult to install than the instructions implied. The lathe weighs 1000 pounds and I had no ceiling height to use a forklift, so did it with a shop crane. You need a buddy to help with this. You cannot assemble the base, bolt it to the floor, and then place the lathe on it. You must place the lathe on the loosely assembled base so you can line up the mounting bolts to the holes. Then I found that toe clamping it to the floor was easier to do than marking the holes through the base, moving the machine, and drilling the holes and moving the machine back. There was no room in the pockets provided for the floor bolts. Once leveled, and clamped to the floor at 8 places, this machine is surprisingly accurate. Several things I did not like: Bolts that hold compound are indexed in the cross slide so as to make it impossible to lock it down at 90 degrees. Carriage and cross slide locks are wimpy setscrews, but seem to work minimally. Machine was a bit noisy But is quieting down as it is broken in. There are several chips and scuffs in the paint and labels. Carriage handwheel set screws are in an inconvenient location to set zero. The swinging cover at the spider bolts at rear of spindle is just plain in the way, making indication of long shaft difficult, unless you remove it. Still, I have wanted my own lathe for 40 years, and now I have one, and it is nice to make projects any time I want.
