Let me know what you think! I will post more as I finish assembly.

Thanks!!

Very nice resto, is it a single phase drill?

 

[RbrtAWhyt]

That thing looks beefy. Are the holes in the mounting plate on the back of the motor there so it can be secured to the wall as well as standing on the floor?

 

[woody 73]

Very nice job,please keep showing more pictures...

Yeah where is the motor? Just noticed that lol.

The original motor is a 120 volt, single phase. I have this motor and have used it for 10+ years but will not be reinstalling it.

The plate is for the motor, it slides on 2 posts for fast belt changes.

I am making a change, I will post more as I complete the re-assembly.

Thanks for all of the interest.

I just picked up a couple older looking new in the box motors for projects like this. Now to find the project


looks nice. love the older tools myself.

I just picked up a newer (early '70s I believe) Sprunger Bros. 15" drill press at a garage sale for $40. It's in great shape. I'll get some pictures of it this evening.

 

[Bigpigdave]

I finally had time to finish this project. I added a DC motor to allow for fast and easy speed changes. Check out the pics and let me know what you think.
Thanks for looking, Dave

This is a fully assembled pic from the right side, the paint turned out really nice. It is custom color Rustoleum with hardener. I sprayed it with my DeVilbiss Finish Line gun.

You can see the motor controller box I put together in this pic, it also has a light (from Menards) mounted on it. The box is from Radio Shack.

The DC treadmill motor (from Surplus Center) along with adapter plate and spacers are visible in this pic. So far the motor seems to have very good power at all speeds although it spins pretty fast at max RPM's.

Awsome work!! Now I've got to find a treadmill motor for my mill/drill.

Check these guys out. https://www.surpluscenter.com/
They usually have a pretty good selection of motors and controllers at very good pricing. Watch out for motors without the proper controller available, it can be a real pain to find a controller that works.
Good luck, Dave

 

[Bigpigdave]

Surplus Center has some really nice DC controllers available right now. Anyone needing one should take as look.

Dave,

Could you provide a closer shot of the fabrication of the DC motor mount?

Also, any hints on wiring the controller?

Thanks.

 

[murph64]

Cool beans, who *doesn't* dig the old stuff?

And this week I picked up a treadmill motor and all the electronics from a neighbor. It'll either end up on the benchtop drill press, or the horizontal spindle on the mill.

Dave,

Looks like he used part of the treadmill mount that's already on the motor.

I have a PDF of the factory wiring diagram from a Proform 545 treadmil, give me a few to convert it to a format I can post/attach.


edit - I've attached the file, if anyone wants it in PDF format shoot me a PM.

edit - I've also attached a pic of how to use a router speed control to slow down the motor

Here are some pics. The motor mount is just some 3/8" plate with multiple tapped holes along with some spacers to provide for some belt length. The motor controller wiring was just "plug and play". I was provided a wiring diagram with the controller.
Good luck, Dave

Andy and Dave,

Thanks for the excellent information. I have an old drill press that could use a good facelift and this is just the ticket. The problem with most drill presses is that they don't turn slow enough for drilling metal.

There's always mechanical speed reduction with a flange bearing, shaft and another pulley. Borrowed the pic from here - http://www.pirate4x4.com/forum/showthread.php?t=311507&highlight=crawler

They are awsome drill presses, some of the most accurate available. If it needs repaired don't be afraid to tear into it, very easy to work on. I can't wait to see your pics.
Good luck, Dave

I just found a model DP14 laying in the back yard, its in good shape but the motor is fried. Any idea where to get a motor for it? It is a Westinghouse with a gear reduction. I do have the specs on the motor if anyone can help.

 

[chargerjoe66]

Anyone?

 

[Beaumont67]

Great restoration & use of a DC motor & controller.

Does that allow for PTI speed changes (by dialing in) without touching the belt / pulleys ?

Any 1725 RPM 1/3 or 1/2 Horsepower motor should work fine. You don't need to find one with gear reduction. All of these presses used cone (step) pulleys to change speed. Check Ebay, Craigslist and your local electric motor rebuild shop. You should be able to pick one up pretty cheap.

Thanks for the compliment! Yes, you can change speeds on the fly just by turning the knob. The motor I ended up using turns pretty fast so I still use the pulleys for speed reduction. so far I have been pretty happy with the set up.

[northernborn99]

Well done

 

[nar719]

Can anyone tell me where to find a machine pulley for the Springer DP15 drill press? I checked with Sprunger Engineering, and they told me that they no longer have any more in stock.

 

[Outlawmws]

Dave, is there a cooling fan internal on the motor, or did you just omit that part? Maybe they only need it when in an enclosed housing?

(I have 2 TM motors; I plan on using one on a Clausing 8520, and one on an Atlas H mill)

No idea where to find a proper pulley, keep a watch on ebay. Good luck!

I chose not to use a fan on my motor. I think it was an intregal part of the pulley/ flywheel. The motor has worked fine so far. Good luck.

Old thread, I know. To the OP, I'm about to pick up what seems to be a Sprunger DP15 in really good condition. I've had my eye out for an older delta-rockwell, but haven't come up with anything lately. I'm really looking for a project and came across the Sprunger.

What are your thoughts on this drill press? I've searched a bunch on the web and vintagemachinery.org, but it doesn't seem like there are too many of these out there. From what I can tell, they came with a jacobs 33 taper - is that what yours has? Also, how hard would it be to get the head off of the column? From what I can tell, there is one bolt that goes through the head to hold it in place. I may have to remove that to transport it back home...

Any more info/advice you can provide before I pick this thing up would be appreciated.

 

[Outlawmws]

Travis, if it's setup like the OPs' 15, that bolt cinches 2 wedges to seat against the post.

If not, it may be simply a set screw. in either case don't be surprised if the head is stuck on the post with rust... So be careful with the head, as once free it can simply drop like a stone. often twisting it around the post will free, it. but take something to lube it...

What are you hauling it in? I usually simply tip a DP over and lay the head on my furniture dolly, and then lift the base and roll it into my van. You can do the same for a PU truck...

 

[TravisT]

Unfortunately I got rid of my trailer about 6 months ago, and I have an FJ Cruiser. Great vehicle until I need to haul something big.
