Just received a new Porter Cable dovetail jig:
I wish to use the jig for the joinery on some pretty heavy duty drawers out of 3/4” (18mm) baltic birch plywood. The router bits are brand new also, they’re the Porter Cable router bits that were supplied with the jig. I had a tinker earlier today and had some pretty awful tearout on the front side, I had a sacrificial piece clamped in the jig and got no tearout in the rear, which will be the outside of the drawer.
Here’s my awful first try with the router at full speed:
This will definitely show inside the drawer.
In the next attempt I tried the router at its slowest speed. The tearout is better, but still not any good. You can see this on the dovetails below.
I then tried to remove the majority of the waste with a 1/4” straight bit which also resulted in tearout, as you can see below:
I’m sure others use this jig for cutting dovetails in plywood. Any tips to help me out before I have to look for another way to do it?
