[AT] OT: keyless drill chuck

[Indiana Robinson]

	Trying to catch up on messages...
	I have a pair or 1/2" Ryobi 18V drills and a 12V 3/8" DeWalt. I have 
very little trouble with slipping but I tighten them the way you are not 
supposed to...   :-)   With the drill in high gear I back the chuck 
fairly open so that it has room for a running start, set it back to 
forward and hold the chuck ring tightly in one hand and hit the trigger 
so it spins down and pretty much slams against the bit. I have several 
sets of woodworking spade bits that have hex shanks and I love them. On 
round shank bits used in metal working when they get burrs on the shank 
a quick pass on the 1"x42" belt grinder keeps them going back in the 
rack. The funny thing is that after being ground smooth again they seem 
to slip less. I guess it is the rougher surface that the grinding leaves 
than the original factory smooth surface.
	I have thought about setting up some kind of jig to grind three flats 
on each bit. Like I said, I have "thought" about it. It hasn't happened 
yet...   :-)
	A bit of lube inside of the chuck between the sleeve and the back of 
the jaws seems to help it tighten better.
