View Full Version : Chucking a hanger bolt in drill press chuck

I have some ball shaped finials we bought for drape rods and I need to sand them between coats of finish and am thinking the easiest way to do a good job is to chuck them in my drill press by the lag screw. Will this damage the drill press chuck or the lag screws? I realize I would need to be careful how tight I tightened the chuck.

Thanks

Since you are just sanding, perfect alignment is not required. I would wrap the machine threads of the hanger-bolt (I assume you mean hanger bolt and not a lag screw with a hex-head?) with tape and grip it just snug enough to do the job. Enough tape should pad the sharp edges of chuck and screw and act as a buffer.

You can cut the head off an equivalent bolt and grip the smooth shaft in the chuck. The chuck jaws are hardened and won't be damaged.

I think you're looking for trouble, especially if the rods have any length to them.
Even at 100 RPM they will whip and vibrate.
If your abrasive grabs x accident you can get hurt.
Without support on the opposite end you're looking at Calamity Jane.

Since you are just sanding, get a piece of wooden dowel, drill a hole in it lengthwise just smaller than the diameter of the screw, screw the ball into the dowel, and check the dowel.

I am not sanding the rod just the finial unattached to the rod.

Assuming it's steel, the threads will be fine. Test it with a spare bolt and see what happens.

Lag screws are cheap. You'd get a better and more concentric grip by cutting the hex head off and chucking on the bolt shank. I do it often.

If the turnings have hanger bolts, put on 2-3 nuts and clamp the nuts in you chuck. Just make sure the flats on the nuts are aligned so the chuck jaws have a flat place to bite.

If your drill press is running too fast to be safe, slow the speed down.

Use a coupling nut to grip the machine thread part of your hanger bolt. You might want to add a jam nut below coupling nut.

The bolts are lag screw thread on both ends so they can screw into the wooden finials and the wooden rod. Bruce's suggestion is the best and is what I am going to do.

Thanks Bruce Page. For me sometimes the simplest solution escapes me.

You are welcome. Been there, done it. If chuck on DP isn't large enough to hold coupling nut, just cut a short section of a machine bolt and screw into coupling nut for chuck to grip.
