Well here I am with my 1st post. I’m a new woodworker that has become hooked. I’ve converted my 2 car garage into my woodshop, (the inside never to see a car again!).
My question is regarding a Delta 8″ dado that I have. I’m trying to make a box joint jig. I’m using 3/8″ for the pins. This should theoretically should require an 1/8″ chipper to be inserted in the dado. When I do this and perform a test cut, I’m 1/32″ over on the cut. I can’t figure out why. I have the test piece clamped down so it’s not moving. I fiddled with the chipper setup on the saw. Is it a problem with the dado? or am I seeing a bit of runout on the tablesaw? It seems to me that the longer the joint the more error I’m going to get.
What is the best way to correct this for making the box joints? I’m thinking about using a 1/16 chipper and shiming it out to get precisely 3/8″. But I wanted to use the best method. Since I’m trying to make a jig, I want it to be setup perfectly so I can make trouble free joints.
Any replies are appreciated!
