   What method are you using to measure the runout?

   Model # would be helpful also.

   I can go back and measure. I can center the drill bit, but it would go side way as it comes down. The model is 11-990. They don't make them any more.

   Can you remove the chuck and measure the runout at the end of the spindle?

   Not counting the chuck there are three components in that model that can affect the amount of runout.

   Do you have a copy of the manual?

   I'm attaching an exploded view so that we can be sure we are using the same terms.

   Is the entire quill moving sideways or just the spindle?

   There is lots of room for the quill to wiggle side to side in any direction. I'll remove the chuck and check it

   You are talking about part #44 in the drawing right?

   If the quill has that much play in it that is not good news. Either the quill is worn or the bore through the head is worn and there are no adjustments to compensate for that wear on that model.

   The quill should have no detectable lateral movement when wiggled with your fingers.

   Thanks for digging up the user manual. Yes, I will need to open it up and look inside. The funny thing is the problem was there since I got the machine, but I wasn't particular about it until now that I need to do precision work. It got pretty annoying to have the drill bit traveling sideway when it enters a stock.

   Delta part is rather expensive. I upgraded the 220V switch to my Delta 50-760 for $33.00 (cost of the switch) . I went on Grizzly site and saw the same switch for $3.50.

   I need to see what can be replaced.

   Quang, It sounds to me, like your table is not square to the line of travel, not a problem with the quill. Does the table pivot side to side, for angled drilling? I did a quick look at the link that dgreen posted, and it looks like it does. If that is the case, just loosen the tilt, and square it up. If there is a lever or knob which can lock the quill in the down position, and if there is a lot of slop in the quill, you can tighten that knob a little, which may make the up and down travel a little harder, but it will take a lot of the play out of the quill.

   Good question!

   Not the perfect solution but I 'fixed' my old junker drill press by drilling a hole and tapped for a 1/4 inch brass dog-point setscrew. Adjusted for wear of the brass tip using a Ny-Lock nut. My spindle always went off in one direction though so it solved the problem.

   I've saved a few by doing the same thing. I did 4 setscrews spaced around the collar.

   It may be the only option he has. I used an aircraft length bit and did the two opposing holes at the same time .

   I purchased one of those Delta bench-tops about 8-9 years ago. I took it home and had excessive quill travel. Took it back to exchange and checked the other Delta's on hand. All had excessive run-out at the quill. I opted to go home with a Ryobi $99 10" bench-top.

   It was great until I got a floor model. I sold it for $50 to guy in the muscle car restoration shop where I worked for his home shop. He swears by it. Yeah.. I know that Ryobi is junk but.. not in this case nor in the case of the 3 x 21 belt sander I still have which both proved to be a values at $99.

   I did put a piece of duct tape over the Ryobi label though and wrote Fess-tool on it. It works ever better now. ha.. ha... ha..ha..ha..

   Regards...

   I'm watching this thread with bated breath-- I, also have a Delta benchtop drillpress, and would like to check it. It sounds like it rattles.

   The tapped screws would be the best option IMO. On industrial drill presses they split the head and add an adjuster bolt to handle wear and slop down the road just as you are encountering.
