I am getting ready to remodel my office and will be making all new base boards and door casings out of Red Oak. I did some practice pieces and they come out what I will call wavy and not smooth. I am running my router at 10k rpm, feed rate of medium to slow and have a double stack set of feather boards right before the bit. The bit is a brand new Freud so it should be sharp and the router is a 3 1/2hp, so why can’t I get these casing boards to come out smooth.

Any help would be greatly appreciated.

Make two passes. First pass have the fence 1/16” proud. Then come back and do a slower clean up pass after resetting the fence even.

Pictures would be very helpful in us diagnosing your problem. Most likely your problem is caused by something in your setup having some play. Are you using a fence? Have you tried feather board for both the in-feed and out-feed?

I am doing it in 3 passes with the last being the shallowest cut.

I do use a fence but I have not tried a set of feather boards on both the in and out feed sides only the in feed side

What size bit are you using? 10K is pretty slow unless you are using like a 2.5” or larger diameter bit.

If it’s the 99-315, then you are spinning it way to slow… it’s designed to run in lower HP and single speed routers, so can do up to 22K easily.

FYI there’s lot of router bit speed charts on the Internet. That bit should be @ 18000-22000 RPM’s
