Round over edges or cut dadoes first on oak?

Since oak is a bit splintery, would you round over the edges of a board first or cut the dadoes, then round over?

If you're routing the end grain with the roundover, and the dadoes are with the grain, rout the roundover first. This way you won't tear out the grain on every dado when you cut them. I made a card holder for my Dad with some fancy routed bead around the board, and I did it this way. Hope this makes sense.

Depends where the dado is Bob. If your concerned about tear out on the end-grain. rout the right hand first doing a climb cut(right to left ) just for a couple inches then go back and rout the rest the proper way left to right .

Thanks guys, Guess I should have explained a bit more. There are dadoes 2 1/2" wide across grain on board 66" long. 2 of the dodos will be on the ends and one in the middle. I am mostly concerned about tear out / splintering on the sides when I do the dadoes, if I round over first; but then I'm just a wanna be WWer ;-))

Thanks for the reminder about climb cutting the end grain.

With a bearing bit you have to be careful that the bearing doesn't fall into the dado slot because that will mess up the round over. With a fence it isn't quite the same problem.

I will be using a fence. Thanks for the pointer Karson. Never know when that learning curve mistake would show its ugly face to me ;-)

Good idea Jonathan, I'll do that.

Bob, I agree with with has been said before. in addition I would think about scoring the edge of the proposed dado cut to further reduce the likelihood of tearout.

Make sure too aned have a backer against the edge you will exit from, this again reduced the "blowout".

Good luck, let us know how you get on.
