Recently I notice a slight wobble in the 10" blades. If I have tried a few blades, some brand new and all have a bit of wobble in them. They cut ok but Im wondering if the wobble is something that can or should be fixed? Using a wobbly dado causes the saw to shake badly so it cant even be used.
You might see if you can feel any play in the arbor bearings. Un-plug the saw, pull the blade off and grab the yoke with one hand (you might have to reach under the top from the back) then grab the arbor shaft with the other and pull up down front back to see if you can feel any slop between the two . If so, it's time for bearings.
Did you have any accidents or kick-backs prior to noticing the problem?
Get yourself a low cost dial indicator and check the flange and the arbor for runout. I have some video demonstrating how this is done.

's in the "Table Saw" section. The video shows how it's done with a TS-Aligner Jr. but you can use an ordinary magnetic base or make your own fixturing to perform the same tasks. The wobble might be caused by a lot of different things, some dangerous and some harmless. In either case, it will adversely affect the quality of your cuts. You might just find a dirty or dinged flange, loose arbor (all easy to fix), a bent arbor, or bad bearings (a bit more difficult). No telling until the measurements are made. If you have seen it on several blades then it's not too likely to be a blade problem (unless you have managed to do the exact same damage to all your blades).
Let me know if there is anyth> no incidents with the saw. I first noticed the problem several weeks ago
So, have you determined the problem? I went out to the Powermatic site. The parts section is run by WMH tool group (Jet, Wilton, Powermatic, Performax, Columbian, Polishmaster, Waxmaster). It looks like they have only 16 Powermatic items listed in the parts list. I found this information on the Powermatic home web site:

if you go to any of hte parts listed they take you to a complete product like table saw. Their parts site is completely useless. It will require a call....thanks for the info.
I did find the problem. The wobbly dado was missing a sleeve insert that allowed it to fit properly on the 5/8 arbor. Luckily I had another sleeve and now hte wobbly dado works fine. I think the 10' blade runout I see has always been there. I could not induce any play in the arbor so I bet the wobble I see is probably within or close to spec since the saw cuts fine.
The original sleeve was probably dropped on floor during a saw blade organization project putting them on dowel hangers and swept up into garbage.
