The variety of joinery and decorative patterns possible with the PantoRouter™ is limited only by your imagination. With some simple math you can calculate template sizes and how different guide bearings and bit diameters would work with them.
Matthias has a good video explaining this, which you can find in our video library or click here
The formula is fairly simple to use.
Add the desired tenon thickness to the router bit diameter and multiply times 2, then subtract the guide bearing diameter to find the template height.
Desired tenon thickness is 1/2"
Your router bit is 1/2" diameter
Your guide bearing is 7/8" (22mm) diameter
((1/2" tenon thickness + 1/2" bit diam) X 2) - 7/8" (22mm) guide bearing diam = 1-1/8" template height
The length of the template is figured the same way.
Add the desired tenon length to the router bit diameter and multiply times 2, then subtract the guide bearing diameter to find the template length.
In this graphic example, a 5/8" bit is used with a 1" guide bearing to make a 1/2" tenon.
