I have to admit, I'm really jealous of that saw......I'd love to have one.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

I plan to do something similar behind the blade, with provision for dust capture when the arm is at 45 degrees, too.  I have the front port hooked up on one of my saws, but taped over on the other, and see no effective difference in how much dust the saw captures, so that port will get taped off on the new saw.

I agree about that front port. I closed them off on my MBF and a 925 I had. My current saw (1030K) has that port on the back of the guard and I have it hooked up, but only because I was set up to do it. It doesn't catch anything.

Cabinet shop that I worked in a couple of years ago had the same saw. They had it set up to cut countertop blanks. It worked really well.

Nice score, I'm following this with much enthusiasm.
I no longer build museums but don't want to change my name. My new job is a lot less stressful. Life is much better.

I had some time this afternoon, so I decided to take the motor apart so I could check the bearing numbers to be sure I order the correct ones.  This motor is much easier to disassemble than either the GWI or MBF I rehabbed before.  The outboard fan cover just pulls off when the nuts are removed from the ends of the rods.  Then I found that the fan was bent.  Clearly, someone had worked on it at some point and bent the fan.

Fortunately, it wasn't cracked.  I pulled it off; didn't take much force to do so, then thought about whether or not I could straighten it or should even try.  Well, of course I'll try.  I found a 3/4" steel rod to fit the bore of the fan.  Then I cut a hole in the middle of a piece of plywood put it over the fan and clamped it hard to my bench.  I slid the rod into the arbor hole and immediately saw it leaned to one side.  So, carefully, I tugged on the rod to see if I could bring it plumb.  To my surprise, it didn't take much force to get the rod more plumb.  A couple more tugs and it was pretty close, so I put it back on the saw arbor and could see that it's much better.  I'll leave it be now.  

With the fan off, I removed the nuts and rods that hold the motor together.  There was no obvious way to pull off the end bell the rear bearing is captured in, so I got a big rubber mallet and whacked the end of the arbor.  Sure enough the shaft moved and the bell on the blade side popped out of the motor casing. A few more whacks and the shaft was loose enough to pull off the front bell and saw armature.

I did this with the motor still in the carriage.  How nice not to have to remove it and then have to realign everything after reinstalling it.  

The rear bearing end of the motor was full of sawdust.  Somehow, there had to be an opening somewhere, though non are obvious.

With the armature free from the motor, I pulled the front bell off with a 3 jaw puller, then both bearings.

Both bearings were worn to point you could hear them running in their races, definitely time to change them.  Everything else looks great, though.  

The whole job took less than 30 minutes.  I hope reassembly goes as smoothly.  It's probably going to be a couple of weeks before I get the new bearings.

Looking good John! The "tuning up" and maintenance work you're doing now will pay huge dividends later. As for the back table, I first saw a version of it on the internet somewhere so no "theft" took place!

You're going to have a very nice saw for a bargain initial investment!

The DeWalt is a good saw, but it's a toy compared to Wadkin.

The Wadkins is truly a work of art.  There's also Graule, Uni-point, and a couple of other really, really robust radial arm type saws.  You probably wouldn't want to try taking any of them down into a basement shop, though.  I had the possibility to buy a Uni-point, for cheap, too.  I passed; just too big and heavy.

Well, that's interesting.  I called the "guy in the video" something other than "an person".  Nothing fowl, just an observation about his lack of intelligence.

Back in town after a week of sunny, almost spring like skiing in CO with a friend.  While I was away, the bearings arrived, so today I put the motor back together.  

I installed the bearings in the same way as on the other Dewalt motors I've done, heat the bearings and chill the rotor.  The big bearing dropped right into place.  The smaller bearing, just like on the smaller saw I just did, went part way on, but then had to be driven on the rest of the way.  I wonder how many people have forgotten to put that bearing retainer ring onto the shaft before installing the bearing?  I'm glad I wasn't one of them.

With the bearings on I put the front bell over the front bearing.  I thought the heated bell would just drop over the chilled rotor/bearing assembly, but it didn't.  It went on maybe halfway.  From there I had to drive the bearing into the bearing recess in the bell.  

[Image: AP1GczMSd2f5t8x2-Mjcf2GC-PJNj1Ql3I4QWtAq...authuser=1]

With the bearing seated, I turned the assembly over and installed the front ring and machine screws to pull the bearing retaining ring tight against the inside bearing race.

Next, I installed the Woodruff key on the other end of the shaft.  

[Image: AP1GczMqW4C74L5UHUXd0gv7Ut2f5V1uPiXc_5BN...authuser=1]

And with that done, the whole assembly was ready to go back into the motor housing.  

[Image: AP1GczNBjBNqDhQ3R4jk34bhrdva8I2wfosmRUZz...authuser=1]

The rear bearing housing goes on next.  

[Image: AP1GczOZcoolmc_Q-Rp-Hhv3IPofZ_W1v2dthdsi...authuser=1]

I inserted the motor retaining bolts through the motor, slid the bearing housing over them, and tapped it into place with a plastic mallet with only light force.  I added the nuts and tightened them.  The fan then went onto the shaft over the Woodruff key.

Finally, a thin washer and retaining clip are installed to hold the armature from moving axially left/right.

When I disassembled the motor, I found these homemade spacers between the fan cover and bearing housing.  

[Image: AP1GczOdEfPaKH5An-JwOrWhEzAlF6BfMi1dJmJ3...authuser=1]

With them in place there was a gap of more than 1/8" between those parts in order to keep the bent fan from hitting the cover.  Now that the fan runs a lot truer, those spacers are no longer needed, so the cover fits tightly to the bearing housing, as it should. 

[Image: AP1GczNtLXMs-bQENhpVAtC_EoJXd9RlPgZyzsrd...authuser=1]

With that, it was done.  It took longer to put back together than take apart, maybe an hour.  Still, not a bad job.  

When everything gets back to room temperature, I'll see how it runs.
