Full Metal Dovetails

This plane will have brass sides dovetailed to a steel sole. The side plates will have the tails and the sole will have the pins (to resist the wedge trying to push the sole off). I’ll probably do this just like wood dovetails, using a silver bearing solder as the glue. If my pins are sloppy, I’ll lightly peen (ie smash the metal into the gaps) and then solder. As a soldered finger joint seems to be strong enough, dovetails are mostly for visual appeal (ie if the sole and sides were the same metal, I wouldn’t go to the extra work).

This photo shows the evolution of the side plates: the drawing, marking the tails on a plate and the machined plate.

Here, I’m gang machining a pair of plates with a 60 degree (30 in wood speak) dovetail cutter (1/2” wide at the widest, 3/16” tall). I first removed most of the waste with a regular end mill to minimize wear and tear on the dovetail cutter. Real men do this operation with a hacksaw and files (see Bill Carter’s Technique’s).

    Hi,

    Very interesting stuff here. Can the body be all brass? I have just a hacksaw and some files and wonder if it would be easier to make the body out of brass instead of brass and steel.

    Thanks

    Sure, I like different materials because I want to see the joinery. Wood works and brass is much harder than wood. Brass is much easier to work than steel. If you wanted to, you could even mortise in a brass blade bed but a wood infill would probably make more sense. Also, you probably want to use a two piece sole as my design would be difficult to do without a milling machine.
