I had several requests to make more of my hexagonal tumbling blocks coaster. they are pretty streightworward to make other than the glue up procedure. the parts slide, crawl, jump and move….
so, i decided to make a jig:
to make it, you will need:
base board (mdf or plywood, 3/4” works best)
piece of mdf, slightly wider than your hexagon
start by gluing the offcuts from cutting the parts of the hexagon so they make the “press” from both sides.
make sure you have no glue in the “corner” (its actually better to file a little dent there)
now, rip the mdf to 1/3 and 2/3
take the 1/3, drill in it a hole that just bout fit the bolt. the bolt should screw in with some effort but not too much, it will break the mdf. countersink one side or the hole, put some wax (tallow?) on the bolt and bolt it in.
put some glue and brad it to the edge of the board (if its not on the edge, its going to be harder to use the spanner). make sure its 90 degrees!
now, take the 2/3, cross cut “dove tail” (blade at 15 degrees) in its middle (leave at lease 2cm on both sides)
hold the 3 parts together and brad the sides to the board (you can also use glue – i did not). put some wax on the middle part to ensure it slides smoothly.
screw the static side, wax the bottom and “press” and you are done!
perfect glue line every time.
