I have this old wood plane with a different kind of iron. Its 3 piece. Its a cap iron and the other 2 pieces have a angle like they are sharpened. They are two rusty to really tell if they were sharpen together or in some other fashion.

Can anybody tell me anything about it?

The top small nut is grooved so it rides in the slot. At first I thought it might be a way to adjust it, but that wouldn’t work. I’m stumped.

Record had a stay set blade. Might be something like that.

I’m taking a wild guess. I’ll bet the thick one is to stiffen a thin cutting blade. Tool steel costs much more than cheap iron. The cap plate holds the thin blade to the stiffener and you have mass with very little high grade steel. Like I said, a wild guess.

BTKS beat me to it. That would have been my guess as well.

I would suspect that they made the extra iron to be able to fit the plane that had been made for a meatier iron.

The other option would be that this was an attempt at keeping the bed for the iron stable to prevent chatter caused by seasonal movement in the wood…it did not work out well, which is why you don’t see this often.

Don I think this is just some one who had two irons and stored them in the plane like that.
Perhaps one for rough and one for smoothing.
I feel quite confident that it is not a doubble cutting iron, think about the shaves, they will automatically get stucked.
Best thoughts,

I don’t think so Mads. The middle one is way to thin to stand on its own and the cap iron only attaches to the outside “iron”. So if the outside (thicker) blade wasn’t there, there would be no way to attach the cap iron. I agree about the shavings getting stuck, but I think it was made to work as a set somehow for some reason.

I think you are right it is a set – but?

I would like to see some photos once the rust has been removed.

I think I figured it out!
The thin iron is acually the only one cutting.
The thick is fixed behind and set just where the thin one ends – and act only for stability.
The chipbreaker is a chipbreaker.
But why?
Because you can sharpen the thin blade in a few stokes and it is cheap to buy new.
Like a kind of early disposable blades.
I know there were many discussions abot the time for sharpeneing on the thick blades in the old day.
It’s acually really interesting and really unique.
Big smile buddy,
Mads

Really interesting Don, I have not seen one like that anywhere!

Curious to see how it will perform.
