Tenon Cutting Question

Hi all,
I am working on 2 small oak hutches. The side panels consist of a 1 by 3 oak frame with 1/4" oak plywood panels inset. I have all of my grooves cut. I am having a hard time getting nice stub tenons on the end grain of the side rails. I have tried cutting the cheeks with a dado blade but I get too much tearout. Should I try this on my router table? I am also thinking about making a regular sawblade cut on my tablesaw to establish the shoulder of the stub tenon and then cleaning out the excess with the dado blade. Any suggestions? Thanks.....BB

Try using a backer board (put a piece of scrap wood behind the side rail) as you push the rail through the dado blade.

Also score along the lines with a knife, that will help to.

Hi, BB! I think you have your situation well in hand. If you have a router table, you can certain make the stub tenons with a straight bit. Here is a reference from PTWFE (next week's lesson on the Forum) that shows making the shoulder cut the way you are thinking - (figure 3-65). As posted above, by beeg, scoring first with a knife works wonders!!! Also, as Paul said, use a backup board if routing.

If you make the shoulder cut first, you can actually form the whole tenon without adjusting your saw. Just make small bites of the remaining wood. Your fence will not allow you to cut any deeper into your rail.

Thanks for the help. How deep of a score do I make?

Score = slicing through the surface grain. About a 32nd inch up to 3/64ths.
