The Dado's from your wobble blade sure don't show any problem. I have often wondered about the bottom being cupped on wobbles. It didn't make any sense to me. If you bent the blade then I could understand there being a problem but if the blade is just held at an angle I don't see there should be any cupping the diameter is not changed. But I have been wrong before and I'm probably wrong now however your pictures seem to prove otherwise.

The carbide teeth on my wobble are slanted. At least the particular teeth that extent to the outside when the wobble is enlarged are slanted more than other teeth. As I look at the other teeth they are slanted less, until the teeth that stay near the center - they are flat!

The result is there is very little concern about the uneven bottoms. The 3/4" dado cut is dead flat! As the dado becomes smaller a slight raise in the center of the cut happens. It's not really noticeable until the 1/4" cut. I've not cut a 5/8" often enough to remember how that works out. However, I can tell that with the wobble, at least one tooth cuts every part of the bottom of a cut. There are no uncut or rough strips.

Once again, this is the wobble offered through Shopsmith. (At least it was) I don't find it in the 2007 Holiday Catalog.

That's what I bought. I figured it's worth the investment now for something that I'll have for a long time.

I bought a Freud SD508 Super Dado set for $150 shipped on sale at Amazon.com. Actually, I just checked and they are on sale again (clicky clicky). The reviews are quite favorable, and shipping is free. On the SD508, the inside chippers have four wing chippers. The reviews are impressive. I haven't used it yet, but I'll need it for my ceiling shelving project.

When this sale was going on before, I also bought the 10" Freud 40 tooth thin-kerf blade with PermaShield coating (clicky clicky). It leaves a very nice, smooth cut even when crosscutting. It's a step up from the 40 tooth Vermont American blade I bought from the local big-box store.
