Craftsman Drill Press Restoration

[meatness]

I know this isn't the first or the fifth or probably not the 20th drill press resto on here but hey, might as well have another. I am heading over to vintage machinery to get some more information on what I am dealing with. Here are the before pics. This will probably be a slowish restoration, too many things going on at once, but I do need to get it up and running so I can use it for another project....

Doesn't matter if it's the 1 millionth, bet this thread will still have followers! Looks pretty complete, mind getting a few better pics of the speed reducer setup? What are your plans on the cracked cast pulley cover?

You already **** since you have the middle pulley option for more speeds !!

Good luck with the restoration. What model number and vintage ??

I have seen people on here braze the cracks in cast iron, this is probably the option I will chase. It is something I can do with the tools I have and done well I think it works out. I snapped a couple more pictures of the jack pulley.

I can't find a number plate anywhere on the press. I really don't know what it is yet, I am going through atlas and companion press pictures on vintage machinery trying to figure it out. It's a slow process but hopefully it will pay off.

It looks like I am going to have to make a new tightening wedge for the jack pulley. That shouldn't be too big of an issue.

Thanks meatness, I think that is the first "long C" DP I have seen with the original speed reducer, the wedge should be no big problem to make.

Outlaw should be along shortly to help out with a model number or other pert. info.

Very nice machine. That thing is OLD.

What is the diameter of the speed reducer bottom fitting? I might be able to take the measurements of the wedge off of mine.

Braze that housing up no problem. I'd braze from the inside, let it flow through real good and then grind the front smooth. Should be near invisible from the front.

Cool I could use all the help I can get. This is as close as I have gotten so far. I can't find anything that says this isn't the same machine. The measurement from the post to center line of the chuck is the same as this machine and markings are all the same.

That appears to be the same model, good find.

From the long "C" and that blue color, I'm guessing late 30's to 1940 as far as DOB.

DITTO!





That wedge is nothing more than a square bolt with slight bevel on opposite flats. That should be an easy fix.



Mine was a model 101.03581 and had a slightly different table with X pattern slots as opposed to the parallel slots on yours.

Wow thank you for the pictures. The wedge looks a lot simpler than I was going to make it.

Looks like I am missing the plunge depth set up. There is one on ebay right now but it doesn't have the collar and I am not sure if it is the correct one. If anyone out there has a source for replacement bearings/parts please do throw me a bone, I would very much appreciate it.

It looks like the wedge is just a beveled square bolt, shouldn't be an issue. I like your idea of flowing the brass from the back, I was thinking along the same lines.


Does anyone know what the slowest speed would be with this set up on this drill press? Or how I could calculate it?

 

[meatness]

I did my own work, pulleys are as measured from smallest to largest.

1"
2"
3.25"
4.5"

The motor speed is 1750 rpm and all three pulleys are same just flipped. By my calculations that would make the slowest speed about 109 rpm. Does that sound about right?

 

[meatness]

This is from one of my other posts:



For a three-pulley calculation, you'll need to do the above twice. First for the motor to middle pulley, then from the middle pulley to the spindle pulley.

1" seems kinda small. Are you measuring from the outer edge of each step?

No I wasn't, I was measuring from the ID of the pulley surface.... guess that's wrong. Thanks

So my correct slowest speed is around 214 rpm with the measurements of the outside diameter of each pulley being
1.75"
2.75"
3.75"
5"

Since they are all of the same belt style it won't matter as long as you keep the measurements consistent as it is just a multiplier of the ratio. What you really need to measure is called pitch diameter. IIRC I think it is ~200 RPM on the low end with a 1725RPM motor. I have the 15" version of that press.

It looks like you're also missing the spindle cover. There is one on ebay now on BIN at the current going rate.

The model number would be on a plate pinned to the base between the work surface and the post. Yours may be missing, but there would be holes for the pins in the base. I agree with the others that your DP appears to be an early to mid 1930's #101.0358x model made by Atlas.

Here's an image from the 1957 catalog that shows the speed reducer. The description shows the speed range. 200rpm - 9835rpm (assuming your motor/spindle pulleys are the same size as the 1957 DP's)

Cool. Great information! The spindle cover will have to wait until after christmas. Hopefully there will be one available. Thanks for the heads up. I knew I was missing it but had no idea what to call it.

 

[meatness]

I found about an hour so I took advantage of it. A little time in the blast cabinet and now I can really see the damage on the pulley cover. I am calling it character, once I get some sand I will see what I can do to braze it up. The broken piece is sitting a little proud of the rest, so it may be difficult to blend it in...

Hello. Found this post in Google looking for the model 101.03581 I have now. I got it at an auction for.... $25 in working condition, not original motor and a wall switch over the Craftman plate at the side... I started cleaning and painting it. They make them later 30s to beginning 40s.
