Making Moulding Planes - Wooden Planes

I have a few projects coming up that will require some rather large matched hollows & rounds and I've had some trouble finding what I need with out spending over $1k for a matched set of 20. SOooo it's time to make em myself...

I was unable to locate any 8-10/4 beech locally however I was able to trade a guy over on the barter site for some 4/4 so I decided to go with laminations to get the ball rolling. The picture starts off with a glued up blank marked out for my tongue mortice and mouth. I'm basing the dimensions and angles off of my other planes so the iron bedding angle is 50 deg and the opposing mouth angle is 60 deg.

I got the mortise started, then used a hand cc saw to establish the mouth.

Finished the through mortise, widened the mouth. Then I planned out my radius and started with a jack, then to a finely set block and then to sand paper.

It's not pictured but I slapped on a coat of BLO and set it aside to work on the iron.

I marked out my blade on some oil hardened 1/8 starret brand steel (unsure of grade). The temper has previously been removed and I was able to cut it with a 12 TPI high tension hacksaw.

Then I installed it after a bit of tweaking with the grinder, marked my profile and went back to the grinder with it. The wedge you see pictured is from one of my other old planes... I'll make it it's own later and sharpen the iron.

This was all done this morn from 0700-1130 so it's been a bit intensive but I think it's going well. I'll sharpen the iron and run some test after lunch and Jr's Dr apt.

Take care, and thanks for looking!

Very nice. But is that a round or a full half circle?

Insert witty signature line here.

It's sort of an offset round the idea is that it should allow me to cut sort of a half tear drop shape by leaning it to the side. It's probably going to take some refining to get to what I'm wanting though. Because of that I'm going to play with it for a while before I use it to match the match which is already roughed out but even close to completed.

That's so confusing I think I just got brain freeze!
When you are done half-teardropping it how much of a circle will it cut? Half (gutter planes and bullnoses) or 1/6 of a circle (hollows and rounds)?

Very cool, but...

I see the wood marked, then cut, I see planes rounding over. Then I see steel marked, and then there's a blade.

Nothing Showing the steel being cut, sparks, swarf, no fire. :(

I used a hacksaw! No sparks or flame there! But here's some fire all the same

Ahh! I follow ya. Yeah I think what I wanted and what I made may be two different things I played with it a bit prior to tempering the blade and it's not really what I had in mind.

Not having one already I didn't know what I needed. I am going to have to make the plane much narrower with the same radius to do what I'm wanting. Learning every day!

They are "sized" based on the radius of a the circle they match, but they don't cut the whole circle (obviously impossible) and they don't even cut a half circle (those are the bullnoses).


Most hollows/rounds 1" and under cut an arc 1/6 of a circle. By some freak of mathematics that also means that a hollow plane sized 4 will be 1/4" wide and will cut an arc equal to 1/6 of a circle with a radius of 1/4.
And a round plane of size 8 will be 8/16" wide and will cut an arc equal to 1/6 of a circle with radius 8/16.

There are a few books out on the subject ranging from cheap to expensive. I think there's also all the info you need on the internet if you've got the basic wood cutting stuff down and just need the math. Here's a starter link:

Thanks, Joe! I appreciate the link. I was unsure of how the numbering but more importantly the radius segments went. I think that's all I'll need!

I just want to say thanks for another great thread (in progress).

So Tom, when are you going to have some ready for sale???

Glad you enjoyed it so far. I got the blade hardened then tempered and then polished and honed around 0400 this morn. I tried it out before heading over to the mill for the day and it seemed to work very well. All in all though it's a LOT of cutting surface to push through wood so all the more reason to take note of Joe's info above.

As for "ready to sell" probably never, lol. Unless someone out there needs a special profile and either convinces me I should make it for them or is willing to pay decent $ for it

Thx! I'm not sure what this steel is, lol but an odd lot box for pretty cheap. It hardens and tempers pretty well though. Thanks for the offer, I'll remember that if I end up in need.

So no progress with your plane project?
