My router has a depth stop and integral back-off wheel so that I can
set the final depth and lock it, and then back off the router for a
small first cut, and the steps on the adjustment wheel allow 1/8"
incremental cuts. I do use this when not confused. It is obviously
necessary with larger bits of understandable geometry, and I have
broke a 1/4" Dia. straight bit at a depth of 5/8", just trying to get
a good estimate of the depth I had set in a test piece, after a short
distance. Forget about it with a smaller bit, or a larger I guess.

I just did a bunch of 1/4" roundover, and also 1/4" rogee at the edge
of some 5/8" mdf. I did it all at the final depth, no increments.
These are small bits, 1/4", so think I just got away with it. I was
prepared for it to let go at any time, but I had already started. I
was using the companies best Ti-C bit set. But I do not know the
teachings when it comes to these kind of profile bits. What is the
rule. Is there any difference from other bits? To be honest the
question is a little premature because me ain't even considered what
type of bits need only one pass because of the actual profile
generated, if necessarily possible. If I don't find out I may be in
for a rough ride.

the computer reading Pat's stuff, and you'll be a lot further ahead with
the practical, doable side of routing.

And most of the stuff he sells is first rate, too.
