View Full Version : Delta Toolmaker Surface Grinder Project

Picked this up on e-bay for short money. Looks even better after I cleaned up the dried oil some. Note the 2 way electric chuck. Perfect size for the garage.



I spent a bit of time tearing it apart and stripping it all down to bare metal. The tables are in a friends shop being re-ground. This thing is heavy.

Gave everything a coat of some awesome sealing primer called MASTERSERIES that is used on bridges. I'll give it a finish coat of machiery gray when I pick up the paint.



I honed out the main bearing, and cleaned up the spindle on my lathe.

All the hardware has been cleaned and wire-wheeled.


Also made some dolly parts so this can be on wheels when I want to move it, and can jack down onto pads when it is in place. These are not the bolts I'll use, but hopefully you get the picture.

I got the tables back from my friend who re-ground and squared all the way surfaces.


The original handwheel shaft and bushing had some wear so I made new ones.


I painted most of the parts with some industrial paint - A little lighter color than I wanted - But I'll get used to it.


Coming together. Right now the top part is done, and the spindle all set.

The secret for doing the lettering is to use paint markers. I did this in less than 5 minutes.

very nice job, I wish I could find one in any condition.

Wow, fantastic job! That sure as heck ain't a Rustoleum rebuild! :)

Very nice job. Is that an adjustable angle mag table on it? It looks like someone made a fixed stop on the left end.

very nice. Mine was a nice addition to the shop.

By the way, did all the Toolmaker's have plain bearings? Most I've seen have, but I'd swear I saw a post about someone rebuilding a Toolmaker spindle and it had ball bearings?

That's a sweetheart of a machine! Nice find and resto job. I noticed that the machine was once sold by Max Leach. I bought a 16x54 LeBlond from him about twenty years ago. He was a character, I wonder if he's still in business.

Thanks for the kind words.

Carld: Someone did make a "support" brace for the front of the chuck. If I take the brace off it can adjust in 2 planes.

lazlo: The spindle has a ball bearing in the rear with the outer race free to float axialy, The front is a tapered journal bearing that matches the shaft shot. There is not much adjustment between slop and locked up on this. I guess that the purpose is that you can continue to adjust out the wear of the journal.

Nice job

I got some "ME" time in the shop today and got the machine assembled! I still have to square up and adjust the gibs - but it will not change how it looks. This paint will stay this glossy and will hold up against gas, oil, etc. It is thick stuff!

Thanks for taking the time to snap some pics and share with us. That looks like just the ticket for most small shops.

That is an exceptionaly nice job you did. That mag table may come in real handy.

The finished machine is a credit to your efforts GDA not only the refinishing but the SAFE mounting of castors keeping the C of G so low down. The number of abortions we see where the owners just stick wheels under the frame!!! :rolleyes:

Circlip: Thanks - This surface grinder is crazy top-heavy , even on it's base on the floor. I also just posted another thread with a dolly I made for my Bridgeport that people might like.

That's a nice looking job!

Mine is still in pieces, and I still have to de-rust one of the sides of the base. I think mine may be a bit newer, as it has a steel base instead of the cast iron. Maybe sometime this year I'll get it cleaned and painted and re-assembled.

By the way, did all the Toolmaker's have plain bearings? Most I've seen have, but I'd swear I saw a post about someone rebuilding a Toolmaker spindle and it had ball bearings?

The later versions of the grinder have what are described as "preloaded precision duplex ball bearings" instead of the tapered plain bearing. These are easily recognised by the motor below its support and the drive belt on the front side. The vertical handwheel is also horizontal instead of vertical.

I wish I had time to finish the rebuild on mine. Two years and it is still in pieces. The spindle is done, but that is about it.
