I have a 'pre-production' shot (attached) and will, if you or anyone else is interested, do a few more detailed pics.
I used oak for the two V rails, which received a good coating of slippery wax and the front and back fences (18mm birch ply) are raised about 1mm off the table. I used a set square both sides of the saw blade to set up the perpendicularity(?) of the back fence - seems to be good. Thanks for the idea, I love the finished tool - far cheaper than the Festool sliding table!
