Hi all, hope someone can share some insights on a possible remedy for the subject matter.
I have this MicroLux Variable Speed Miniature Drill Press with 1/32"~1/4" JT1 chuck. MicroLux's ad says "high torque motors will drill a 1/4" hole through 1/4" brass easily" and that may very well be true regarding the torque but the darn thing looses the chuck as soon as I start drilling anything (metal or plastic) thicker than about 1/8" with a drill bit or any considerable size, say larger than 1/8". I was thinking that, this being a friction connection, maybe some oil got on the taper or into the chuck, cleaned both with isopropyle alcohol, reset by twisting the chuck counter-clockwise (looking from above) - still to no avail. The chuck would fall off the very next time I drill any significant depth / size.
The taper looks OK to me though I'd be hard pressed to gauge the straightness of the sides by just looking at it. The chuck looks kinda fine, too. Both being rather small, no imperfections would really jump out on you of course but they both look rather ordinary and I don't really have any precision measurement instruments to verify that.
So, should I try another chuck and see if it helps? I am assuming that I cannot do anything at all about the taper itself, so I would be looking for some plan B in case a different chuck does not help.
So, is there a trick of the trade that may make a taper like the chuck a little better, so to speak?
Thanks!
