« Part 1: 1975 Rockwell/Delta 8" Jointer 37-315 Part 2 of Vintage Restorations series Part 3: Stanley Bailey Hand Planes »

Here are the pictures of the completed project.

Photo of the motor I rebuilt for the jointer. It’s a 2Hp 1Ph Baldor. It was originally a blower motor, now has a second life doing more than just moving air. It purrs like a cat, very smooth operation. It also barely fit in the cabinet, glad it did. Original motor was a 1Hp 3Ph Dayton.

These next two photos are pictures of the interior of the sheet steel cabinet. I used a roofing product called “Peel and Seal” to dampen the sound and vibrations caused by woodworking. Some of you might wonder if this is overkill, but I say nay! Using this stuff really cut down on noise and vibration, the latter of which is the death of machines. The former is the death of my ears, and they’ve taken enough abuse. (Playing the drums since the age of five, guns and more guns, yada yada) For those that have a sheet cabinet, you might be able to attest that they can be quite the attention getters. I know the one I used in shop class was.

For those of you who wanted to know, this is my makeshift bearing press.

Ok, enough yakin. Here’s the money shot!

And what do you know, it even makes wood chips! Much better than the piece of eh hem that I got from the local tool store. Returning it was the best tool decision I’ve made in a long time. The tables are decently coplanar. So much so that for 37 years of use and abuse, the tables are flat to 6 thou. Can’t beat that for American manufacturing! The knives are going to be replaced, I think I’m going to buy some Freud knives. The last thing I’m going to mention is that I don’t know why people say that setting the knives is a pain in the neck. I followed the instructions given in the manual, got each knife set to .002” in about 3 minutes a piece. Really. It was that easy. No magnet, no crazy contraption that plugs your brain into a supercomputer. Just two straight edges (diamond honing stones in my case) and the indexing key that this jointer was designed for. The original was missing, but some quick fabrication solved that issue.

Another nice restore. I agree anything to help dampen the noise is a good thing. I’ve started to do a lot of my work with hand planes just for that reason.

She’s beauty and a beast of a tool. It will serve you well because it’s a good machine. Nice work,

I am currently looking at the same project, 3ph motor change out to 1ph what Baldor frame size (?) did you use if I am looking for a replacement motor? Thanks! Datmole.

56 Frame, doesn’t matter what brand, all 56 frames will have the same bolt pattern on the base. I would upgrade the hp rating on the motor that you choose, 1 Ph motors have different torque characteristics than 3 Ph. Make sure that your RPMs are the same, or you can do some math and use different pulleys. I really like the Baldor brand, customer service is excellent, and used motors can be had on the cheap (I picked up mine for $30). Oh, their quality is also top notch :) – Rich

Good restore. Caution should be taken when repainting motors. This can cause them to overheat and the result is a damaged motor.

Great restore, i like the black a lot. I just picked up a 37-220 that looks pretty similar to your machine. Mind if i bounce some things off of you if i get in a bind?

I love the black paint and the sound deadening material inside the base. I was able to pick one up this week for $350. It is in pretty good shape but could definitely use some nice black paint!

Any idea how much these things weigh? We used an engine hoist to lift it into the truck and a few of us to get it out.

Me and a buddy got it into my truck without too much trouble, I’d say it was maybe 250, probably no more than 300. – Rich

Rich – I have the same model jointer and need to replace the bearings. Can you let me know the bearing codes for the ones you installed?
It appears that the prior owner of my jointer either installed the wrong size bearing or the bearing housings are worn – the end result being that the bearings can slip back and forth inside. The old bearings that I pulled out were 6204Z.

Any info would be appreciated and thanks for your time.
