Dovetail Jig Dust Collection Jig for PC 4200 series

Jig Size

The Bottom of the jig is 14 1/16" long- 5 3/8" deep- it is cut at a 30 degree angle with a 3/4" 90 degree piece at its 2 wide end sides. It is cut from a 1/2" piece of plywood

The top is 13 3/8" long and 4 1/4" deep cut a t 30 degrees it is cut from a piece of 3/4" Plywood. Cut an extra top using 1/4" luan for different thickness.

The sides and back are 1x2's cut at 30 degrees. Covering the 1x2's sides are luan pieces used to snug the jig to the brackets and bolts.

The design was limited to the available hardware. Fortunately I was able to make things work from what I could get from my local hardware store.

The L brackets had to be bored out to larger than 3/8", the size of the bolt that holds the template and now Dust Collection Jig. They also needed to be bent to 30 degrees or the angle from the jig to the bolt. When I did that there was a gap on each side. That's when the additional luan side pieces were added.

To hold the Template in place I used 3/8" x 1" T-Nuts and 2 3/8" by 1" washers. The Porter Cable knobs are now used to hold the Dust Collection Jig in place. A standard Shop Vac 2 1/2" to 1 1/2" reducer was used and inserted in to a drilled hole saw hole (1 1/8" ?)

The Design is based on William M. Porters design https://www.portercalls.com/napkin_holder.htm
