Carl, I am interested in the possibility of using the Moxon to hold a board and rout out waste with a trim router (I am about to build a new Moxon vise) - I have an idea ...
In this design, the front chop has a rebate. As the chop is set up in the design above, there is full support on both sides of the board when sawing. Now reverse the chop, and the rebate on the outside becomes a rebate on the inside, and this provides space for the router bit to clear the pin board.
At the rear of the vise is a hinged spacer. This has three purposes; firstly, it lifts the tail board above the chop, which would be cut up by a knife when transferring marks if coplanar. Secondly, it is easier to align tail and pin boards if there is space around them (which is why I dislike the designs which have a continuous shelf at the rear of the vise. Thirdly, the spacer becomes a ledge to which one can attach clamps (if needed).
Most of these ideas (the exception being the rebate in the chop) I have been testing for at least 10 years, in which time I have hand cut thousands of dovetails.
What do you think?
Regards from Perth
