This is why:
(a) Splines on shafts = Very Good
(b) Woodruff Keys = Good
(c) M4 Grub Screw on circular shaft = Bad
(d) M3 Grub Screw on circular shaft with pulley made from cottage cheese = Utterly pathetic, and shouldn't have made it past prototype.

Much mirth.

Couldn't agree more. Having to resort to a dab of superglue to stop an M4 grub screw vibrating out of its thread is a bit daft IMHO.

Superglue??? Duct tape no less!

Seriously, use Threadlock which is made for the purpose. Recently I made a similar comment in some humor forum that had no relation to any of this at all and I was taken to task by a guy who gave me a brainwash in anaerobic adhesives and why the cyanoglues (not his term!) in general distribution were inadequate for the job. In the end he told me he was the senior engineer in charge of the Loctite research lab

Funny! Yes, amongst all those people who know a little and like to aggressively expound it in internet forums, we often forget that senior engineers and subject matter experts visit forums too. How frustrating it must be for them!

BTW, I didn't put superglue on the threads, just a a dab on the grub screw flatted end.

Where did you get that awesome t-slot table?
