Did a couple of things: pressed the nut/washer combo together more tightly in my vise, and cleaned up some gunk from the washers. I still see a very slight variation when I hold a machinist's rule on the table while turning the blade by hand, but it is much, much less pronounced than before. Between that and truing up my table and rip fence, I'm getting much smoother cuts.
I suppose one can spend too much time truing the table and fence and if so then I am extremely guilty. Once they are trued when they go out I believe you will recognize it immediately. The first thing to do when you sense that cuts are not right is check all the table locks, quill lock, etc.
Your comment about the nut and washer in the arbor does not ring the bells. I gotta go look more closely at my arbor which I have never had apart.

A nut and washer on the sawblade arbor???? Sounds like he may be using the wrong arbor!! The 5/8 arbor for the dado set or the universal arbor are NOT intended for sawing operations.

[quote="chipmaster"]I used a much more low-tech method: I held a sharpie on the table up close to the blade and turned the blade by hand. The warp was noticeable via the skipping circular pattern. To check the runout of the shaft itself, I set the table up underneath the shaft almost touching it and turned the shaft by hand. There was no rubbing. If there is runout, it is beyond my eye's ability to detect. I'm convinced my problem is with my blades. One was an old one from the SS's PO]
My preferred method for checking wobble (don't think that is a proper term for runout) is shown in the next couple images. The wobble on this arbor/blade combination is .003"-.004". I don't know that I have had better.

Thanks for the notice!
The arbor I chucked up for sawing had a saw blade in it when I got the machine, so I just assumed it was the proper one. How can I tell a proper sawing arbor from a general purpose arbor?

For those of you with your smart phones, don't forget there are various level apps that let you do this with your phone. With the Android phone, I've found the swiss army knife app usefull for this.

Huh? Are you telling me that a smart phone can function like a dial indicator or micrometer?
Looked at the picture. Totally different arbor. Luckily my new Mark V came with at least one of the proper arbors, or I'd be SOL. Now I just have to figure out how to work the thing.
