Here's the thing that helped me route the purfling and binding channels on no 2 and no 3
It's got 5 recycled rocking chair bearings, a bunch of washers that i use as spacers and a thing that holds the handle and i insert that bunch of material on a single long bolt(~3 1/2 " long) and lock it all up with the nut at the base of the bolt.
The upper sliding plate and the fixed base plate are from plexiglass(3/8" thick). The fixed base plate is attached to the router base with countersink holes and the upper sliding plate has 2 legs to clear the bolt's head and has openings to make the adjustments for the channel's width
here are the 2 legs under the sliding upper plate
The fixed base plate has only 2 holes to accept the philip bolts and wingnuts that i use as a locking system for the channels width
Here's a pic of all the components and tools i used to disassemble the jig
And finally, how it indexes from the sides and how the router bit distance is adjusted from the bearing itself
Thanks for watching
Serge
