Anyone familiar with the ER-40 collets from Little Machine Shop? Is their quality good enough for the average hobby guy? Thinking of biting the bullet and buying about a dozen of them. Also thinking of buying one of their Collet Chucks to match.
It's the female taper in the chuck that determines the accuracy, the nut simply clamps it into that taper. I've made nuts and see no diff with factory nuts. If you want a collet chuck with thru hole capability you pretty much have to machine your own to get the taper aligned with your spindle.
