Dovetail Jig and Splintering Plywood
I am making drawers for a sewing center. I was going to use some birch plywood, but when I tried to router the half blind dovetails in the plywood, it splintered. I used several different speeds, which helped some, but it was hit and miss.
I have a PC 4112 dovetail jig and have used it before. All of the drawers I have made to this point with it have been solid wood. There have been no issues with solid wood.
Has anyone had this type of trouble with dovetails in plywood?
The other issue is that the dovetails are very tight. There are two guide bushings with the jig and I am using the larger diameter per the directions. I thought the smaller bushing is suppose to be used for the half blind dovetail.
Then, I tried to make a drawlock joint, but my plastic router insert has such a sag from my Freud FT2000E, that it is difficult to make a decent joint. I just ordered an aluminum plate. I remember arguing with one of the sales people from MLCS about the plastic plate when I bought the table from them, but they kept telling me that it wouldn't sag. The polymer chains creep over time and take a permenant set.
