Rockytime Posted November 13, 2018 Report Share Posted November 13, 2018 Not being too ambitious today I decided to check the runout on my small drill press. I have an old but excellent American made chuck. The accuracy is quite exceptional. I measured a 3/8" length of drill rod. Drill rod is not necessarily perfectly round but very close. A 3/8" dowel pin is more accurate. The runout on the drill rod is .0015". OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
zimmerstutzen Posted November 13, 2018 Report Share Posted November 13, 2018 I have been looking for a small drill press. Every one I looked at had a wobbly spindle. I was given a 100 yr old Companion by Sears. absolutely no wobble, but It has an odd thread, so I can not replace the old worn out chuck without ordering a chuck from Australia for $100. . 1/2 x 28, not the common 1/2 x 20. So for really fine drilling, I mount a pin vise in the drill press. Been drilling some really fine stuff that way. wire drills that I need magnifying glasses to see to mount in the pin vise.
