I don't know if you're interested, but here's the binding routing jig I made.
It's main components are a drawer slider, an aluminium solar panel mounting bracket and a nylon cutting board.
I had to shorten the drawer slider, which is a task not recommended for the faint of heart. The Makita laminate trimmer's power cord is quite thick and unyeilding, and comes out right where it's most unwelcome.
Also, if I was to make another one, I would use both drawer sliders (comes in a pack of 2) as there is a bit of lateral pressure when you're cutting the channel and although it's not critical, (the bearing dictates the depth of cut) the amount of movement was visibly noticeable.
The nylon guide - I used a holesaw to cut out a disk from one of the missus' cutting boards. I then screwed it onto to a coach bolt, (you know the ones with the round head and square shaft immediately below it?) The square bit held the nylon disc in place, I put the coach bolt into the drill press, put it on the highest speed, used the drill press vise table as a tool rest for a very sharp chisel. That's how I got the rounded sides.
You just have to make sure that all the bits of timber for the mounting frame are all perfectly square.
