thank you

Full Disclosure: I do not have a set to have in hand to examine.
However I think that however they are to be set up with chippers between them is the same way they should be set up without chippers.
Do not the tooth bevel angles alternate between 'groups of teeth'(between deep gullets)?
If there is set in the teeth, they must be stacked so the teeth do not interfere with teeth in the other blade.
I believe blades in question do have alternating tooth bevel and tooth set.
If so one 'group' of teeth will both bevel/'set' to the right and the next group of teeth will both bevel/'set' to the left.
Lastly they must be mounted so the correct rotation direction occurs for both blades.
Other than that above anything else looked at may lead to confusion.
The way I 'see' it.

If they mentioned tooth breakage they were probably talking about dados with carbide cutters. The Shopsmith dado set would be very difficult to break a tooth on. If you look at the photo of Brenda's Freud dado set carbide cutters you can see why slippage could cause breakage.
I went one step further and found my dado set (purchased many years ago from Shopsmith though it is marked as Freud). I believe it clearly shows that image III depicts the proper setup. Hope this helps without confusing the issue.

Here's a photo of how mine is configured. It may be wrong but does a great job. I was always told to never stack them together with the same tooth pattern side by side so my cutters are lined up with the rakers.
