A Light Restoration of a Dewalt MBF Radial Arm Saw

https://www.youtube.com/watch?v=AlPt-AQs7iY&t

I recently purchased this 1956 Dewalt MB / MBF radial arm saw. The saw could not be plugged in to test, so I took the saw apart, rewired it, painted it, built a new table for it and dialed it in for making 90 degree cuts. This is not meant to be a tuturial on rehabilitating these old saws, but to show my experience performing a “light” restoration. For more information on these saws, check out the DeWalt Radial Arm Saw Forum—http://forums.delphiforums.com/woodbutcher

and the super helpful video: Radial Arm Saw Alignment/Calibration—

Here are the products that I used on the saw:

Very nice Brandon. I’m sure you’ll get of lot of use from that wonderful old tool.

Nice job on the restoration, Brandon. I would call that a “full restoration”. Once the paint comes out, that changes everything (to me). BTW, what is the blade size? It looks to be 10” but I know DeWalt made larger models. I’m guessing 10” since the wiring looks like standard 120V. I am also anxious to see if the radiator hose works without clogging.

Love it, well done. I need to replace my bearings, especially seeing how quickly your motor went to a stop.

Thanks guys. So it wasn’t a “full restore” because I didn’t replace the bearings and the capacitor/resistors. I felt like those on the Dewalt forum would have taken me to task for calling it a full restore for that reason. The bearings seem fine, though perhaps down the road I’ll swap them out, I just wanted to make sure the tool would run before investing much more money in it.

The MBF is one of the smaller radial arm saws made by Dewalt. It has a 9” blade and the blade I have in there is only 8.5.”

It was pretty similar to restoring a handplane, but with wires. ;-)

Are you going to keep that smaller blade on there? I did order one from Forest that’s the full 9 inch blade.

I’m sticking with the CMT for now. I’ve had good luck with them for table saw blades, but it does feel a little bit like a skilsaw blade in terms of its thickness (hence the stabilizer). Once the CMT blade is toast I’ll fork out the big bucks on a Forrest WW1.
