I'm glad you posted those pics, too. I got a Mortise Pal from a garage sale some time back, but had little to no idea how it worked.
Looking at the size of your router and the size of your workpiece, I'm surprised that the router's weight was supported, but obviously it worked.
F6 Double Sided Tape is a type of adhesive tape that can be used on both sides. It can be used for many different things such as sealing envelopes, sealing rings, attaching small items to larger ones and creating cables with extra connectors.
Bob, I had planned to make another, more “finished” version, but this one has proved to be secure and as good as anything that might replace it. So it has stayed.
