Default Question about cutting dados

Hi, I'm new to Router Forums and to working with routers. I have a fixed base router installed on a router table. I'm trying to make a cross out of 3/4" square hard wood 6" long using dados to flush fit the cross together. I tried using a 3/4" Straight Bit & it tore the hard wood up. I don't know if I took too big a bite or if I'm using the right bit. I also have a "bottom cleaning dado bit 3/4" x 5/8". Please tell me where I went wrong??? Thanks, Bernie

Welcome aboard Bernie.

I'm guessing you want the dado to be 3/8" deep, so the pieces lap? If so, 2 passes would be in order. Also, using a backer board (push the workpiece through the bit with a sacrificial scrap) on the cut will help as well. Keeps from tearing the fibers out on you good piece.

If your strips are not already cut to 3/4" square, you might want to try cutting the dado in a wide piece, then ripping 3/4" wide sections off that--only one "exit wound" that way.

Thanks Earl, I did use a backer board but I'll try taking smaller bits. My hard wood is already cut to 3/4". I thought about cutting the edges out with a band saw, then making passes with the bit. What do you think? Thanks again, Bernie

Hi Bernie, do you mean half lap joints instead of dado?

Hi James, I am really new to working with routers and don't know the terminology. I'm trying to cut grooves in two pieces of wood to make a cross that fits flush. Bernie

Something else I have thought about is using double sided tape and running several pieces through at the same time. I'm working with 3/4 inch x 3/4 inch x 6 inch long Granadillo wood. What do you guys think? Thanks, Bernie

Hi Bernie, did you have a look at the post I had linked in my response?
