I am new to the whole dovetail thing. I bought the Rockler dovetail jig on
a whim for some drawers I am building. The drawers are being made out of
half inch plywood. The problem is that during the routing of the dovetails
i get a huge amount of chipout on the (forget terminology) pins. Basically
the sides of the drawers. No matter what I have tried it keeps chipping.
Is there a trick? Can i back up the piece in the jig with a scrap piece of
wood without ruining the properties of the jig?
You may just be going too fast. I asked about chipout at a show once. The
Leigh Jig guy said, go slow enough that you don't hear any difference in the
router speed between spinning free and making the cut. This is especially
important near the edges of the board. Another technique is to take a very
light climbing cut until you have basically scored the edges. Then you can
be more aggressive on the interior.
I am not sure of the jig you are using but do you cut both the face (or
back) and the sides at the same time? Are these half blind dovetails?
Typical machine cut half blind jigs allow you to cut both the pins and the
pockets at the same time. This can be done with very little if no chip out
if you are careful and follow some simple steps. If this is your problem,
contact me on the back side and I can go into greater detail. Just finished
making drawers yesterday from 1/2 inch Baltic birch and a Stanley jig that
is 50 years old. It works.
Are you making an initial light scoring pass from right.to left ?
Also what type of 1/2 ply? We usually use apple ply for drawer sides
A back up piece is fine too. What I've done before is leave the sides
wide and trim them after milling.
