delta 15-069 drill press worth buying?

[bagged89s10]

Saw this on Craigslist for $125 and wondering if it's worth buying?

condition: good
make / manufacturer: Rockwell
model name / number: 15-069
70's era 15" floor drill press. Good condition. Quill return does not retract properly. Returns manually. Spring might not be seated correctly. Has 3/8" chuck, but will include 1/2" Jacobs chuck. Fairly heavy as you might expect from yesterdays tools.

Yes

Is it difficult and or expensive to fix the quill return?

It depends on what's missing, broken, or disconnected. You won't know until you take it apart to inspect it.

I checked on ereplacemantparts.com and that model isn't listed, but maybe parts can be ordered from another model that will work.

Not really. Someone put the wrong coil pack in there.

So the wrong cool pack is most likely the reason it won't return automatically?

It may not be adjusted correctly. IIRc, There is a screw under the head near the quill that is used to adjust tension.

Might be worth checking out the dirty paper at vintagemachinery.org to see how the return spring is adjusted before you go look at it to have a better idea of what to look for.
Good luck, Jim

Anything else I should look for in particular in an old drill press like this one prior to pulling the trigger and buying it?

I'm just trying to find out if it has a slow speed.

You need to see it with the belt cover open to determine which pulley set it has. The slow speed set has a larger diameter front pulley. I'd grab it before someone else does though.

If it doesn't have a slow speed pulley. Do you know if I can swap them?

You CAN, but finding them might be a different story though.

So a slow pulley set will have a larger front pulley diameter vs rear pulley. Does a fast pulley set have a smaller diameter vs rear pulley or same diameter vs rear pulley?

The front pulley on the slow speed is larger in diameter than the front pulley on the high speed. That gives a larger slow down ratio. The slow speed set front pulley looks more full when you open the belt cover.

You may be able to find a pulley and/or parts here: http://www.hammerscale.com

The seller just emailed me a pic. He said The motor is a 1/2 hp single phase 1725 rpm. Speeds are 700/1250/2400/4700.

Is that a fast pulley set?

I can't see the images, but based on that speed range, yes. The slow speed model only goes down to ~450rpm.

This is really a woodworking DP, and looking at your avatar, I'm guessing you'd be better off with a slower speed model for metal work. One of the best is a Delta/Rockwell 17", usually has the slow speed pulleys, and has a table raising mechanism, and just more rugged in every way. They turn up on CL on occasion, though they are usually more money than a 15", but if you saw them side by side you'd see why. Don't know what part of CT you're in, I have a few of them here, could probably part with one.
HTH, Jim

That image looks a lot like a slow pulley for metal. It fills the shroud like mine does, I'm thinking its a metal version and the speeds given were wrong.

Yea the pulley does fill that shroud and looks like that's the biggest possible for this model. Unless this model was never meant for a slow speed dp. I guess I can just measure the pulleys when I go look at it and calculate it. this the correct way to measure?

Drilling RPM = motor speed x motor pulley diameter / quill pulley diameter

If you look at the parts list that was posted, this model only lists 1 set of pulleys. Not sure why you think the seller would give the wrong speeds?

 

[nine4gmc]

You can measure with a set of calipers or measure the circumference with a measuring tape and do the math to find radius.

I did some looking through my catalogs and parts list. I was incorrect on the spring housings. Looks like the newer versions use the stamped sheet metal housing that is on that machine. The older version that I have uses a worm gear to tension a cast spring housing that has an external gear cut into itself. That should* be the modern wood version with the front DP-256 pulley, where as the 15-070 was the slow speed version with a DP-283, larger front pulley. Both used the same motor pulley. Looks like they also changed the belt guard to closer fit the smaller pulley as they no longer offered the option of the slow speed set :

*From what I can determine from the parts lists. A bit odd as the older version of that press used the lower number to designate the slow speed model and the +1 model number to determine the high speed configuration.

 

[nine4gmc]

That explains a lot Z, thanks for clearing it up as the to ft of pulley to shroud and the tensioner. I'm on my phone app and can't do as much research like I can on the computer.

fenner drives. You can make up any pulley system you want.

The one thing to look at is how much torsional slop there is between the spindle and the spindle pulley. With the drill press off, and the drill chuck fully closed, lightly rotate the drill chuck both ways and see how far it rotates. I recently passed on a beater one like the one you are looking at because the previous owner never lubricated the spindle splines and it wore away the mating splines in the spindle pulley, leaving it with lots of slop.

How much slop is ok?

Looks like this might not be a good buy for mainly metalwork. There are some others on Craigslist I've inquired about for under $150. Duro, craftsman, and others. I like some of the open top models where it's easier to modify the pulley setup or add middle pulley to slow them down.

 

[Whitworth]

What kind of metal working do you plan on doing mostly ?

Chassis work mainly. Drilling brackets and mounts. My current benchtop China dp is nothing but a pain in the *** and sloppy. I don't want to waste time restoring one if it won't fit what I need. I just got an email that this one sold as I was typing this. The hunt continues.

I'd say the one that sold is probably good for holes in steel up to 1/2" and power tapping to 3/8" or so.

For larger holes or if the material to be supported is very heavy or long, you'll want to look at 17" or 20" drill press. Delta, Rockwell, Powermatic, Walker Turner and Clausing are good names.

 

[tool_scrounge]

A degree or two. The one I was looking at had 10+. With the spindle fully retracted, you can see the two mating surfaces. The pulley is the softer material so it's splines wear. On the one I was looking at 70% of the male spline on the pulley was worn away.

 

[bagged89s10]

I just found this craftsman bench top drill press. Don't know anything about it but looks clean and its $150. I know I can put a slow speed pulley on it.

That looks like a model 80, I'm on my phone app and can't be for sure but the way to tell is the quill handle will have one single bar passing through it for two handles. If that's a model 80 for $150, I would seriously pass no matter how clean.
If the quill handle has three spokes on it, it's a model 100 and much heavier duty, $150 would be fair if its not damaged.
The difference in the 100 and 150 is a tilting table option. The 100 table can be tilted left or right. There is a bolt under the table with a degree plate showing angle.

Sorry, but you made a mistake asking too many questions and missed the delta. Should have bought that one.
