Topic tags/keywords: delta milwaukee jointer

Hi All,

I am just getting into doing some woodworking and my grandfather said he had an old jointer that he bought years ago from a woodshop that closed down. He told me that it needed a few things and he had never had the time to get it up and running again, but he wanted to give it to me. As a newbie woodworker on a budget, I was ecstatic. So I brought it home and started looking at it to see what all needed done to it.

Mostly everything looks in pretty good shape, but it needs new blades (blades are missing), a new cutterhead pulley (old one is cracked), and just a little bit of cleaning up. The problem is that I haven’t been able to find replacement parts for it anywhere. So, given the wealth of knowledge I’ve already found on LumberJocks, I thought maybe someone here can help me out.

Basically, I am wondering if anyone knows where I could find replacement parts for it, or am I better off to just sell it and try to find a used one elsewhere that is within my budget and is currently operational. I’ve googled the name and serial number and found nothing in the way of parts. I did find a site that said that model was built in 1944, but that’s it.

Delta Milwaukee
Serial No. 32-6732

Any thoughts/ideas/wisdom?

You might be able to find a generic pulley that will work. Just note the shaft diameter of the cutter head where the pulley mounts, and then the width and diameter of the pulley where the belt goes. Check out McMaster Carr, Grainger or other online parts places and see if something they have matches.

If not you may be able to have one made for you. Take what you have to a local machine shop, or find a local maker’s group (hobbyists with a lathe) and see if they can make a copy for you.

Sweet jointer… Serial number makes it a 1944 model. If it’s a 6” jointer, then it’s either a model 37-205 or 37-207 depending on what base it shipped with. Catalog/Manual states it uses a 2.75” arbor pulley and a 7” motor pulley (the 4” jointer uses different sizes… check the manual). Knives and pulleys are off the shelf items and can be found pretty much anywhere – no need to get OEM parts. You should probably replace the bearings as well given their age. Would make a really nice (and pretty easy) restoration project.

Yeah, the pulley I’m not so worried about. I think the blades are the biggest thing right now. Even those I could have machined if I had one of the old ones, but there are no blades on it at all.

I would never sell that jointer. even if I never used it I would hang on to it. what you would make from selling it would be just change compared to what you have if you kept it. Really nice piece.

If you look at the parts list in the manual MrUnix posted for you, the part number for the knives is #659.
Then google a replacement parts site and this converts to #37-658, google that Delta part number and
you will find various sites that will tell you that the #37-658 is a knife that is 6-1/8” X 19/32” X 3/32”.
Google jointer replacement knives of this size and you will find a large variety of prices. If you are
missing other parts on the cutter head aside from set screws you might have some problems. That is a
good jointer, I have been using one in my shop for quite a few years. It is not as good as a Delta 8”
long bed, but it did not cost you as much either.

If you can get this old unit up and running again, I think you will have a higher quality solution.

In general, the older they are, the better they are built.
