Default Motor end play

Hello all. After reading Oliver's review of the Freud box cutter set, I decided to give it a try. Ordered it yesterday and awaiting delivery. I spoke to my son about it, and he suggested using his benchtop table saw for it so I could have a dedicated unit, since I'll be making a lot of box joints.

The problem is that his saw is a direct drive and has about 1/32" of end play in the motor. Does anyone know if there's any way to get the end play out of a motor? I don't know any way, but someone here might. Thanks. Jim

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

+1.

Next question would be if it is new or still under warranty? If yes, then either take it back or have their service center take care or it. That would definiytely be too much freeplay.

If not, then yes, you can shim the one end or the other of the armature.Depending on the brand, some have bushings that are preloaded with a spring (Ryobi does that).

That's another problem. It's a Shopcraft.

Does the saw move back and forth while running or only when at rest? Maybe the magnetic fields keep it against one or the other bearing while running. Not that I'm condoning that much free play.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

I've only tried it at rest. I'll go by tomorrow and move enough of his junk to get it out and see what kind of cut it makes. I didn't think about that possibility. But either way, I'm hesitant to trust it after spending the money for the cutter set. Thanks.

The easiest access would be to pull the brushes and the back housing cover off the motor... and shim the back of the arbor shaft between the communtator and the back bearing.

I get shim stock from an industrial screw supply or shim washers from an electric motor shop. (The motor shop is further from me, so I do that just for special circumstances.

Why? It is salvageable. Even if it seems to only wander when off, and doesn't look like it does when free-wheeling... once it tries to follow the grain, it will. a few dollars in shim stock is less than much more for a saw.

Sidenote:
I'm glad my father taught me to fix things when I grew up!!! Sharon has this old fan by her side of the bed. I've gladly cleaned and lubed the bearing in it about 5 times over the years. Brushless motor Electrical cleaner. Then turbine oil. I have tinnitus and it's the only motor around here that doesn't make a loud whine to me. She was going to replace it -and- the replacement kept both of us up...

Thanks Mike. I'll see if I can do that. New saw is out the question right now, so I'm willing to do some work to get it going. I'll let you know the progress.
