Cheers, Mick. I don’t have the measurements here, I built it as I went along out of whatever scraps I had. I’ll measure it tomorrow and post the details.
For the guiderails, what you’re trying to achieve is to get the width of the guide-rail (from the edge of the fence) to the exact measurement of the edge of your router cutter to the edge of the router base.
So for example, if the router measurement is 65mm and the width of your fences are 30mm, add a couple of mm to that and cut your guide-rails 97mm wide. You’ll then end up with oversized guide-rails which you can trim to the exact width with the router once you’ve attached the fences.
