When I service one I often find that I can run a 180 grit flex hone in with some hone oil and polish the inside to dress it up a bit. You don't want to remove material, just de-glaze it so to speak.

I also use a small file to take the edge off the keyway corners cut into the armature shaft, followed by a fine hone to insure it is free of burs.

I then take the keyway and clean it up on the hone, followed by some 800 crocus cloth to polish the armature shaft before reassembly.

It should be very smooth and then lubricated with turbine oil etc. to insure it moves freely, then 6-8 drops of oil in the hole every 10 or so hours of run time, just like the speed control sheave which can be treated the same way.

Your local gunsmith may have some of these hones for sale, if not Amazon etc.

Thank you all for your help and information. I won't have time to get back to it until this weekend. I'm looking forward to getting it back together.

Well, the saw is back together and running great. Putting the spring back on was a challenge, but finally got it on. Looked like the problem was just the build up of crud over the last 34 years. It has been maintained, but I guess it could have been better. After going through all of this effort, it will be lubricated more often. Thank for all of the comments and ideas.
