Hi Steve, I think this rotary table was designed to be an A axis for a good sized mill. Thanks for the tips on the Monarch machines. I'll take a look. I was looking around the web and I didn't realize that some rotary table manufacturers make 2 axis rotary tables. Those can't be cheap. Dav

This one weighs considerably more. I can pickup 250 lbs, but I had a hard time sliding this one once I got it in my pickup truck bed. We used an engine hoist to load it as there was no way that two of us could lift it.It is programmable and has some type of air lock device in it also along

Hi Dave: If you can find a 5 axis machine on the cheap that is great. Usually cheap is worn out or/and old technology and 5 axis machines are relatively new. 5 axis profiling machines have been around for quite a while but I don't think they can move all the way around a part, which I think

Using a piece of the electric plane blade, I machined a 1/4" thick piece of hot roll with a dovetail profile that included a high center so as to flex the carbide ever so slightly, but when trimming it to length with a diamond wheel, I overshot it a couple of thou. So I cut a hacksaw slot in th
