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.


You're also cutting in the "right" direction on both sides of the
dado, and hogging out less material. The up-cutter is well worth
the money. The solid carbide cutters last forever.


Yeah, I forgot about that. When you cut the whole slot at once, the
router can get a bit squirrely from the two cuts fighting each other.

A spiral bit is on my wish list. :-)
