Spindle wick hole depths on my 1948 9A with plain bearings: I measure left
0.950 and right 0.675, +/- 0.005. Both holes appear to have been cast.

Wicks Hi, Webb.
My 1948 9A is a horizontal drive.
I will measure the wick hole depths tomorrow.

Wicks Hi
There, Is your 9A a bench top model (back drive) or a cabinet model (underdrive)? Either way, there shouldn't be a difference between the front and rear wicks. I have been inside at least a dozen different ones and this is the first time I have ever heard of this situation. A wick that has been "clipped off" at spring level is usually from someone installing the spindle without compressing the wick and using the skewers to hold them down. I'm with carbure2003; It sounds like something is in the well interfering with the springs ability to be compressed (maybe a piece of old wick spring). Use a piece of wire or something and measure the depth of the wells (front and back) and see how much they differ. If they are really different, you can cut some of the coils out of the bottom of the spring so that it will compress enough to allow the spindle to be installed. As long as the springs raises the wick high enough to make good contact with the bearing journal, you should be fine. I once had a late model 10K (Korean made) cabinet (underdrive) model and the rear bearing was always loosing its oil. I found that when they drilled the well, they went a smidgen too far and just nicked the hole for the reversing tumbler pivot. I cleaned it up with solvent and compressed air and using a heat gun, I dripped a drop of JB Weld epoxy into the well to seal the hole. Good Luck! -Blue Chips- Webb

Nice work. I am trying to figure out how to use 5C collets on my 9C (1949 vintage) when I get it going again. There ought to be some way… There is a way. You can mount a 5C collet chuck on the spindle. You will still be restricted on the size of stock that have to pass through the spindle though. I was considering this route until I decided to convert my lathe over to L00. There is a "kit" you can build from Metal Lathe Accessories for a collet chuck: Metal Lathe Accessories MLA-21 Good Luck! -Blue Chips- Webb

Thanks everyone for all your suggestions and great ideas. I now
have enough to start my design process. I am actually thinking of
machined 2X4 top in a butcher block type configuration. That
gives me about a 3" top. I will use the suggestion in the designs
of using a series of rods across the table to add strength and
rigidity. I will then add a 3/4 MDF or plywood surface for added
strength and stability and finish it off with a 1/4 " hard board
sacrificial top. That should give me the rigidity I think I need
and the smoothness to allow me to do a pretty good job of
leveling. As I said, I won't be doing real precision work (no
bearings or any thing like that) at least until my skills improve
so this should be adequate for my purposes so I'm not too worried
about extremely precise leveling. The base will be made from more machined 2X4s laminated together to give me about 3X3 legs. Cross pieces will be joined with mortise and tenon reinforced with dowels through the tenon. That's about as far into the thought process I have gotten. Again, many thanks for the ideas and suggestions. As an aside, I would be interested in the leveling method David mentioned. If you could describe that I would be appreciative. I too am a little geeky!!

Re: Drill press spindle run out
Phillip Rankin
About a year ago I measured the run out using the same drill bit measured just above the flutes as in this video. Back then run out measured 0.006. now it measures 0.014. I know drill presses aren't precision instruments, and I was okay with 0.006, but 0.014 is way more than I am willing to tolerate.

Re: Drill press spindle run out
Try your indicator on the taper shank of the drill just below the end of the spindle nose and see if you get the same reading. Then take the drill out of the spindle and set up an indicator to read on the inside of the spindle taper and see what you get. Good luck.

Re: Drill press spindle run out
Mark R. Jonkman
If you can get it a part then you could try heat straightening it. If you look on YouTube Keith Fenner does a lot of shaft straightening using that technique. Basically you place the shaft on vblocks or roller blocks and with indicator locate the point of bend. Then apply heat at that point then you hit it with cold water to cool it rapidly. I believe you heat the high point then cool it rapidly - the rapid cooling causes the metal to shrink slightly at that point thus shrinking the point of bend thus shortening that area pulling the bend out.

The alternative would be to set it up similarly in a press - shaft on two v-blocks and pressing down at high point. It would largely depend on where bend is. If it’s at the end where it mounts chuck then probably only option would be to heat straightening. Or put your machine shop skills to work and make new one - easier said then done depending on your skills and availability of equipment Mark

How is the drill press chuck attached to the spindle- a 33JT , a 2MT or what?. Try removing the chuck from the spindle and remounting it.

Re: Drill press spindle run out
Try that again with the the indicator running on the inside of the taper, unless you know you had zero run-out on the outside before your incident. I have a Craftsman drill press that was my dad's when I was a kid. My next-youngest brother, who is a 6'8" 300lbs gorilla, bent the quilt on it about 25 years ago. I turned down the end to remove the bent section, and cut & threaded it and a replacement piece to be loctited on and turned to match the taper on the drill chuck. Threaded on and not loctited, run- out was about .003". This was done on my HF 7x10 mini-lathe. I've not completed it yet, as I've got a better lathe, an Atlas TH42, and an SB Heavy 10L restoration project, and a Lewis shaper. I want to use one or the other of those lathes and the shaper to completely remake a quill with an MT2 taper to replace the original. It's still on hold because I also have a much heavier antique drill press already equiped with an MT2 quill. Drill presses aren't really precision machine tools, so you may be able to live with it as is. Mine had about .250 of run-out. That just wasn't going to work. If I get too pressed for time and need another drill press fast, I could live with the .003 now, I just want the MT2 socket instead of a JT33 male taper, so I can skip the chuck entirely. HTH!

Re: Drill press spindle run out

I had a drill press that was in that condition, and I sold it for parts, but the buyer was convinced he could straighten it with a press / vice. I'm sure it's *possible* but I think it would be rather difficult to do. You may be able to find the spindle / spindle assembly on ebay, though, which would be an easier fix. --Rogan
