Sprunger DP14

[notenuftoys]

Last night I picked up a Sprunger DP14, s/n 78834. Near as I can tell it was manufactured in 1973. It was purchased brand new by the grandfather of the seller, and is bolted to a steel base that weights probably a 100lbs.

For starters, it runs. The belt needs immediate replacement, it's dry rotted and cracking. Other than that, it just needs some good TLC. I plan on breaking it down and going through it thoroughly to make sure everything is clean, bearings are good and it runs true.

As you can see it needs a real good scrubbing. I've never taken on a project like this, so any suggestions and recommendations are very much appreciated. For starters, what's the best way to clean the chuck, table, and post?

I would just use it, change the belt, grease and oil where it needs it, if the bearings are bad you will soon hear them.
Scotchbright and wd40 to clean the rust of the bare metal, since the rust is pretty minimal.

Wow, that's a beauty and doesn't appear to need much work at all.

Good find. I have a Sprunger 15" bench top drill press and it is a great machine, minimal runout compared to other DPs I've owned. The quality matches my delta dp220. Sprunger machines seem to be rarer than the usual brands but every bit as good from my experience.

I used a wire brush in my cordless drill to clean the vertical flutes and emery cloth on the rest of the chuck while the dp was running. Same wire brush to clean table and post. Then oil everything.

I use these for light rust.

Heavier gets a razor blade scrape first.

a short post like that can go on a wood lathe and be polished with 1-6000 grit and end up looking like chrome. (check out some restoration threads on the OWWM site).

otherwise, I just buff whatever I can fit on the buffing wheel.

the table you can use a DA sander with fine paper. use a file if there are any gauges, and file a pattern to take out the swirl marks of the sander and make it look like it was machined.

That DP is beautiful! It won’t take much work at all to make it shine.

Spent a little time this afternoon cleaning it up. Used a wire wheel at first to get the bulk of the rust off, but it wasn't too bad so that went quickly. Then I used steel wool, first coarse then fine on the post, the chuck and the table.

It already looks a ton better! Just waiting for delivery of a new belt and she's almost as good as new.

One question: what grease or oil do y'all recommend for the quill and chuck?

 

[Maui]

Use 3 in 1 oil, or another non-detergent light machine oil.

The table is rare,not scarred from drilling as most are. A great find....

they call that the "Arc of shame"

I have one of these that I just purchased, It has an old belt on it, that I think is the wrong size.
What size V belt did you purchase to replace yours?
Thank you

This is my new to me old drill press....
Thanks
