My take on inboard and outboard spiders

My take on your front spider is, I think the nose wall needs to be thicker to keep from distorting when you tighten to the set screws. The only reason I say that is, I ran into a similar problem with a spider I made to run in my steady rest.

Have you dialed in a barrel with it and used it yet?

Right at 0.400" wall. Think I'd flatten out the brass tips on the adjusting screws before getting any deflection:D Used similar spiders on a few hundred barrels over about 40 years. Never a problem. Having said that if a problem arose I would just sleeve this and redrill or take another piece of stock and make it with 0.750" walls.

A good point though. One reason I didn't give any real dimensions. Some guys might just be comfortable with a variation.
