The next step is to follow the
instructions and drill a hole position on the the clamp board.
And clamp the board exactly
1" up on the backer board. An adjustable square helps here...its rule is 1"
wide.
You place 4" 1/4" carriage bolts through these holes. I opted to add some epoxy
on the heads of the bolts to lock them to the backer board.
Then I add the wing nuts and
tighten the clamp board to the assembly. While the epoxy is setting up, we can work
on the templates themselves.
We
locate the template 2 inches from the back edge and temporarilly fasten it in place with
two screws.
With a 1/2" pattern bit
installed, we route the pin template using the Stots template master as the bearing guide.
Here is a look at the routed piece. The MDF machines very well. Just take your time and be
sure that you have a solid hold of the router.
Then it is time to change the
master template to the other blank and route the tail template.
In a matter of minutes, you have finished templates. This task is so easy, you will want
to make more for specialized jigs. The template master makes duplicating the templates
easy and exact.
With holes drilled in the
template, you position it carefully on the base assembly so that the template is 1/4"
from the edge of the backer board. I use a 1/4" dowel to help the positioning...and
then screw it in position.
With both templates affixed to the jigs, we are ready to make our test dovetail joint.
