I too have a Shopsmith adjustable dado blade that I use and like. It doesn't do as good a job as Charlese' but that might not be due to the blade. Charlese is obviously a better craftsman and some of this performance that we are discussing (criticizing) is not due to the equipment.
This is the adjustable dado that I use.

Is this the correct arbor to be used with the dado blade?

Yes! Looks like a SS 505506.
Any 'criticism' by me was directed to the wobble blades, NOT any towards any 'craftsman'. If anything I said can be interpreted as craftsman related criticism, I be sorry, That was NOT my intention!
The curved bottom is unavoidable, but is more apparent with wider cuts. Perhaps my experience with the uneven depth and the obvious extra cost of the internal mechanism is what made it a curious oddity to some who have asked WHAT it is when they see it!

Is the 505506 a Magna Dado Blade incognito as a Shopsmith blade?
AND I was more concerned about the arbor.
As for my comment about craftsmanship - that was NOT directed. I was implying that some machine defects are well hiden in the hands of a craftsman. EXAMPLE: Charlese' dado with a wobble blade. Either his blade performs more like a stacked dado or Charlese uses it differently than I do.
I say that because he gets square bottoms.
Ah - a new nickname. I'll leave the rest to your imagination.

The first two photos show fitting plywood. These pix weren't meant to illustrate joinery. You'll have to enlarge them. I can take a close up.......

505506 is the molder/dado ARBOR!

I will post a pix of my variable round bottom 'Magna Precision Dado Blade' after I make it presentable! Decades of NON use has caused it to pick a bit of FE2O3 in spite of a layer of oil. Another test for Evaporust!
I do not think Charlese is/has a Flat Butt! I do wonder if a chisel/scraper/sandpaper got into the mix!

Hang on, I'll take some more photos. The blade I use yields very flat bottoms of dados when set at around 3/4". There are slight irregularities when dialing down to 1/4" (a slop toward one side) and dialing up to larger (a raised center) Anyway I'll attempt to get more pix. I don't believe my dados have anything to do with craftsmanship - I just take them as they come. (more photos)
JPG - Thanks for saying you don't think I am/have a flat butt
But my LOML says I do!
BTW- I'll also look at a report in one of the recent magazines about rough bottoms from stacked dados.

I have found this very inexpensive 6" dado blade works great on my MarkVs.
I think the 6" works best for the SS. I use 8" Freud and Systimatic on my Delta table saw

One of the things I love about my wobble is the speed it will adjust to different widths. Even fractions of widths to conform to plywood. It too just 45 minutes to go to the shop, snap 13 photos, set up the dado in the machine, adjust to 3 widths, cut them and get back to the computer.
Here are the photos:

Rather than display all of the photos, I'll just show those showing the shape of the various dados. Notice that the 1/2" dado show a slightly sloped bottom from left to right, but the amount of slope is not great. The 1/2" dado is the second photo.
Yes, I grbbed a piece of scrap wood. You'll notice the split (check) through the piece.
