[[File:mountedview.JPG|left|300px|The assembled dagger]]I designed the shape of the mounting board in OpenSCAD with convex rounded top and bottom and gently concave sides, then [[Tools/laser|laser cut]] that shape out of some scrap polypropylene that was laying around in order to use as a template to help shape the board. I screwed the template onto the back of the board and then it was back to the router table to use an edge-follower bit to cut the timber to shape, this actually took 2 tries as the first time I did it one of the joints exploded apart and flung a bit of timber across the room, fortunately the board I made was large enough for a second try. Once the shape was properly cut out I changed the bit to an Ogee cutter and put an elegant curve into the edge of the board so that it would resemble the kind of mounts that are normally used for trophies or ancestral weapons. The board was then coated with 3 coats of a water-based polyurethane varnish with sanding in between coats, this didn't give as high a shine as I was hoping for but with a little wax polish it still looks pretty good. Next time I'll probably try using either Tung oil or french polish to get a higher shine.
