Router Plane

This is my $0.75 router plane. I used a chunk of hard maple I had lying around for the body. The handles are extra plane handles I had replaced. I used 4”? 1/4-20 bolts that screwed in to holes that were tapped directly into the maple. The blade is made from an extra allen wrench I had lying around I ground it down and sharpened it.

In order to have some sort of depth adjustment I simply took a 5/16 die and threaded the 6 edges of the allen wrench. I wasn’t sure that it would have enough meat for the threads but it works just fine and was simple to do. The $.75 was spent on the wing nuts.

At the rear I drilled and tapped 2 holes. The top hole is for a 5/16 bolt that I ground the head down on and then epoxied a wing nut to it. This bolt hold the blade tight to the plane body once the proper depth is set. The second 5/16 bolt is an adjustment to keep the blade parallel in the hole. I needed this because the hole is oversized. I wanted to be able to put different sized blades in the body. It works great. Here’s a test cut crossgrain in a piece of 2 by I had laying around.

I was wondering if you heat treated the edge? As an allen wrench is built for torsional toughness , which may not much overlap with edge durability .

Thanks and good work!

I did not heat treat the wrench. I’ve read other people’s builds who are far more knowledgeable than i who say that they are already hardened. I was fairly careful to keep quenching the blade while grinding it to keep the temper.

Jeeze, nice work, but couldn’t you have at least used a 1/4-20 BRASS wing nut? Kidding, can’t find the pix of mine..I’d been after the brass 1/4-20 stuff for another project and ended up with a bulk buy..
100 of them, they’re EVERY where in my stuff from the router plane to the tool rest on my grinder to the
hold downs on my air cleaner on the 2×4 carbs on my car..etc etc..

Realy like the execution on yours, I used an offset screwdriver for my blades.

That’s awesome!! Did you have to use a straight edge to keep the dado aligned?

Chopnhack, I used a handsaw to cut two quick (and not very straight) kerfs. It was very late and very cold in the garage and I just wanted to test it out.

Had me fooled! Looks perfectly parallel and straight to me!
