Yup, but that was only hand tapping. A bit of Loctite would be good insurance when rigid tapping. > The die holder I'd have to make as all mine are handled for 2 handed > use. The die holder was only needed because I made do with manual tapping, just using the drill bit in the back for aligning the tap vertically, and winding by hand. With the 1/2" round held in a collet, there's no need for a die holder. On encountering your difficulties, though, I think I'd make one up in the diameter of the largest ER40 collet I have, to maximise grip diameter and area, then make sure there's no oil on collet or tap holder before they go in. > Ignore that grinding noise, its just me thinking. Send me a PM with a > couple pix if you can. Went around the workshop with my glasses on, but the little critters didn't come when called - hold on, there's a couple of pics from when I made 'em. Will send.
