Holy Cow,
A2Z needs to consult an engineer to figure out how to make a T-NUT! Are they going to calculate the moment of inertia to work out the strength charastics in sheer, tinsile, yield and torsional?

I spoke to the manager yesterday – she was a sweet lady, but I know she had no idea what I was talking about. Heck, the only reason I know what you’re talking about is havng spent 20 years working for a structural engineering firm. 
Anyway, I think the guy that you talk with there is a consultant and they are sending him the picture of the slide rest. Surely whoever manufactures and/or designs these things will have input into what I need.
Oh… on another note…
Is this the same mini mill as the one at Harbor Freight ? It looks like the hourse power is slightly less (3/4hp vs. 4/5hp) and its priced a little higher, but other than that it looks like its manufactured by the same people. But my question is does it take the R collet? The only reason I’m looking at this one is that I can get it though Amazon and get points on my card – but that’s the only reason.
