Cutting Dovetails in Baltic Birch

Information on Cutting Dovetails in Baltic Birch

There have been many discussions regarding cutting Dovetails in plywood.  The biggest problem is splintering, this is depending on the type of jig used to cut the dovetails and can be a problem with through dovetails.  With the Porter-Cable Dovetail Fixture and making half-blind dovetails the stock is backed-up to prevent splintering.

Drawer parts before assembly

   

Close-up of the drawer parts in the fixture after cutting the dovetails. Note on the right hand side the unsupported partial pin is chipped.  if you put a scrap piece from the drawer stock to back-up this unsupported pin it will lessen the chip-out.  Remember to do a partial climb cut from right to left to minimize the chip-out on the pin face.

 

 

 

The drawing noted is from Wood Magazine and if you click on the link it will take to the Wood Store and Plans.  This was featured as a free project but has since been moved to a purchased plan.  If you build a lot of drawers it is a helpful addition to keep the drawer sides square to the fixture.

 

Table for Drawer depths to have equal spacing on pins.  Note: you can be less than the min. but it looks better to use the minimums.  If you review you design you can generally modify the drawer heights to match the fixture.
