yes to the latter, and its average is about 5.02mm per 5mm cube but is not linear. 25mm measures 25.04, and if anything, the recess should be big, not so tight it can't even be started with a small hammer. And the hole size isn't shown in freecad, or I don't know how to display it. I'll have to chuck and center up the main body in a 4 jaw and run a boreing bar thru the hole, probably an HSS one, or for threading as a normal carbide chip isn't sharp enough. I'll try that later today. It not quite 5am local time ATM. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
