Hi,
I have a question that may be elementary to most but is plaguing me to a great extent. How to avoid ‘chip outs’ while crafting box joints on a router table. To a broader level How do you avoid chip outs on any cut made on a router table? I am using pinewood as my prototype product.
Thank You Scottyj7

chip out usually occurs on the router as the bit is exiting the cut- In order to prevent it you can do a few things-
first- and most important- you need to back up the cut with a sacrificial piece. It should be flat so it contact your workpiece well.
I don't know what box joint jig you are using on the router table (btw- the tablesaw works so much better for this in my opinion) but the fence that supports your workpiece should back up the cut and prevent the tear out (If you have cut into the fence with the bit at one height and then you lower that height for the actual cut it will NOT back up and prevent the chip out)
the other thing I do at times is score a line- with a marking knife or a cutting gauge, exactly where the bit will exit the cut- this cuts the fibers so they cannot tear out.
you can also exit the cut a little slower- sometimes this helps
Let me know how you make out. What box joint jig are you using?
