This is a specialized plane which comes from my annoyance with making small, stopped end grooves where I don’t want the groove to go all the way to the end of the board which will leave a visible hole in the corner. I normally use a chisel the entire length which makes it very sloppy. With this plane you still need to chisel out the last bit of corner, but the groove can be more consistently cut on a long panel.

I tried to include pics of the build, but if you want to see something in particular, I have other pics of details and the first prototype that I will finish for me.

The plane is mostly cherry, with the wear parts in a harder maple. I sandwiched a steel frame that are the toe and heel of a very small skate. (They were squared up and flattened out after this pic)

I decided to use three screw arms. The center bolt pushes into, and outer nuts pull the fence. This removes the need for nuts on both sides of the body which makes it a little narrower. It also seems to me to be a little better for adjusting the parallel of the fence, although this plane needs it less than others. The two outer rods are threaded into the fence just like metal. 5/16” tap about inch deep. It couldn’t take standing on, but it is stiff enough to hold the fence rigid. The middle screws is 1/4”-20, and runs through a threaded insert in the main body. The wooden knob head and wooden thumbnuts are epoxied onto their metal equivalents.

It is convertible to left handed (or other-handed, depending on what you call right). The two screw arms can be exchanged with the set screw positions and put on the other side, and the pressure plate for the middle arm can bar flipped over.

I also made a big fence hotdog to hold onto, I have found that pressure on the side of the fence while planing is more important than downward pressure on the blade. The iron is heat treated A2 on the tip, the rest of the shaft is relatively soft (and therefore tougher). I even made a tiny little oven to run the MAP torch into.

The hammer is copper tubing and end caps, loaded with lead, so weighs 11 oz. The handle is the same hard maple, not traditional hickory, but for it’s use that shouldn’t matter.

The scribe is more than that. It is to cut both initial edges of the groove. I made the blades with a little flare so that they are just wider than the cutter. The steel is also A2, and hardened, so that it should really cut well. The inner angle is 60 degrees with a standard triangular file and slipstone.

The box is recycled oak from an equipment skid. It is two parts and attaches with leather straps.

A stopped groove plane would be a handy thing. I generally just plow through the end with my Veritas Combination Plane, and then come back and stick in a little plug to fill the hole.

Nice bonus items too, Mike! Hope you get some feedback from your recipient.

Very nice Mike.

In fact, I think I have to nick the idea and build one :)
I get why the toe of the skate is short, any reason why the heel is?

Since the plow only goes in 1 direction, it is to start near the beginning edge as close as possible. That way both ends of your groove can be stopped.

You built that beautiful, huge plow already, so I would be honored if you copied this one. To make the sandwich, I screwed the metal into one side, flattened it, and then epoxied the second onto that. I also had two screws to align it in material that was later removed.

Ahh, thanks, that makes sense – for some reason I was only thinking of the groove being stopped at one end.

I like it. The longer fence for better registration sure beats a router plane which is what I typically use for stopped grooves.

Wow! That is some excellent work. I am glad I didn’t see this before I sent you my swap item.

Fantastic work Mike and super-practical for any handtool user that needs to cut a stopped groove :-) And I would have never thought to make a dedicated marking gauge to go with it and score the edges of the groove. That’s a fantastic companion piece. The hammer and the box are both really nice too. An all-around fantastic swap offering!

Mike,

You have set the bar high for future plane swaps! What a great collection of useful tools, complete in its own carrying case…
I am definitely ‘borrowing’ that hammer head idea!

Mike
