My new dovetail jig.
I bought a Rockler dovetail jig several years ago and just got it out over the holidays and tried to set it up. It feels solid and the instructions are clear. I laid out a simple box out of some baltic birch that I have had in my shop for 20 plus years. I used new bits in a Porter Cable router, tried cutting very slowly but the wood splintered tremendously making a mess and a joint that looked like it could have been cut by an ambitious beaver. Any suggestion before I take a second try with a different material? Thank You! Gary
