I like to work with quartersawn oak but many a project has been
lengthened by pieces destroyed by splintering of oak during routing.
What can I do to minimize this? I have reduced the rpm's to about
14,000, am using a Freud 3.25 hp router (in a table), sharp bits, and
my feed rate is neither fast nor slow.
Perhaps the cuts I am taking are too aggressive? Last night I cut a
rabbet (with a CMT rabbet bit) 3/32 x 1/2 inch in one pass (red oak)
and had significant splintering. Is that too much to take in one pass
or is this just the nature of the wood?
Suggestions?
TIA

cool.
Now when are you going to set the 4/1 fool hook?

It is nice if you can leave some scrap on the end and cut the bad part off
afterwards.
Or, have a piece of scrap next to it to protect it.
Of course you want something simpler.
Do the last bit first, very slowly. That will usually work, but may cause
severe control or burn problems, so be ready for it. Hand holding a climb
cut can be difficult; I always clamp to a sled.
April Fools Day or not, I was getting tired of tear-out on the end-grain of
red oak running through the box joint jig on end and also on cutting tenons
on the flats. Solution was simply to use a utility knife to lightly score
(LIGHTLY) the cut before taking it to the machines. Doesn't have to be
exact. Works wonders.

Unless you're spinning a really big bit, there's no need to reduce the router
speed that much.

Some of both. IMO that's too much to take in one pass, in oak. Probably would
have worked just fine in maple.
Depends on the type of oak, also. IME, red oak is much more prone to
splintering than white oak.
Keep the router speed at maximum and take lighter cuts, and I think you'll
have better luck.

I use various combinations of the following:
Use only high quality, sharp bits; cut your workpieces longer than needed
when possible so you can cut off any teaout; use a sacrificial board to back
up the cut; climb cut corners; take small cuts, use proper speed settings
(generally the highest possible for the bit); make test cuts on scrap with
similar grain direction.
Even then, Murphy may insure that tearout will occur on your last piece, so
cut a couple of extras parts that need routing when you start your project.
