Hello all,
Hopefully this is posted in the correct place, it's been a while since i have logged in.
Anyway I decided I wanted to to do some simple box joint (finger joints) boxes.
I have a Freud double fluted 1/2 router bit (this is what i had in hand). I have this setup in a table with a variable speed control. I'm using 1/2 popular 5 inches wide. I have the bit set
just a hair proud of the board so as to do a little finish sanding back to flush.
I have my Jig set correctly so as to get my first joint cut and then just move the board for each finger.
Here is where I'm getting in trouble and frustrated! the first cut goes find but then after that it is hit or miss. I get might get 1 or 2 joints competed but then I get a blow out on one of the fingers, I have tried full speed, half speed, and low speed! this is a new bit so is very sharp!
This is all on the end grain. So i tried using the long grain side of the wood and I get 100% joint cut out, my 2 pieces of wood match up and the joints are snug but not tight.
So my question is (I know you where going so get to the point already) what am i missing as to getting the fingers on the end grain sides like i see folks doing! I have watched video's at Rockler, and other sites and they seem to cut right through the end grain sides with no issue using 1/4, 1/2 and even 3/8 inch bits. So far I have only cut aromatic cedar on the end grain side and it cut wonderfully no blow outs. I'm currently
using popular and or pine as that is all i have in the shop
thoughts suggestions This should be simple I would think!
thanks
