LOL, about the only thing that is consistent in thickness is MDF.
That and the MDO that I have been buying lately, 3/4" and pretty
much one the money.

And my Forrest dado set works fine for 1/2" Baltic Birch, which is
not 1/2". ;~)

The only size I have issue with is 1/4" plywood that is often 7/32"
so I just make tow passes with a flat grind blade.




Does anyone still buy (or even use) those "undersized" router dado
bits designed for "today's undersized plywood"? Me thinks one would
need an entire set in increments of 1/64"

I tried one and it didn't last long. I don't think it ever matched a
single sheet.
With my jig, you run an undersized bit along both sides of the dado so
you never have to worry about the size of the bit.

In my opinion, you bet a better, easier cut that way because there is
room for the waste to exit. When cutting dados with straight bits, the
channel can easily clog with chips making a more difficult cut. If you
have a spiral up-cut bit that ejects the chips, then it's not an issue.
But those bits cost a lot more than straight bits.
