Super Nova chuck key pin

============================ Another fix is, if you have an old set of dull drills, just cut and use one of those. HSS would be best, but carbon steel shoould do fine.

I've not had this particular problem, but in my case the pin is a little loose and one end of it regularly comes out of the hole on the key body. On a few occasions it's come close to falling out.

How did you fix your concrete nail in place? Just bend the ends over a bit, or something else more "cunning" :)

Just bent the end over Alun, then cut off the excess.

I think you may be right. I have seen turners crank down on chuck keys like they were tightening the lug nuts on wheels for a diesel truck. I don't. I just snug it down tight. I seldom lose a piece. I don't think its necessary to use so much force.

One thing I have found that really helps is to keep the chuck clean and lubricated. Whenever I find that the key feels sticky, I use the shop vac to blow all the dust out of every orifice I can find (on the chuck that is) and then use some graphite lubricant on all moving parts. This makes a big difference in how easily the chuck works, and gives one a much better feel for how tight the jaws are gripping.
