Topic tags/keywords: plane

Hi All,

I bought my first wooden plane recently and I can actually make shaving now after sharpening the blade. However…..the iron is really tight inside the plane body. I mean it is tight against the sides. I can’t adjust the iron laterally at all. Is this normal for a wooden plane or do I need to grind down the width of the iron? It’s so easy on a metal plane but I’d really like to use the wooden one now and again.

Thanks for any suggestions,

Jeff

Yes, Jeff. Grind the iron to width. It should taper in width by about 1/16” with the widest being at the cutting edge.

The iron is tight because the body has shrunk over the years.

Grinding the iron a bit would be the easier of the ways to fix it. The other is to widen the sides where the iron slides into the plane. Takes a special file called a float for that job. So, I’d say just grind the iron a bit. IF you happen to have a belt sander of some sort, use that to narrow the iron a bit. Do one edge til warm, then do the other edge. Then try for fit, keep going until yoy like the fit. Might want to address the wedge as well. Again, a trip along EACH side of the wedge to remove just a hair, and try the fit..

Jeff-
Do what those two guys suggest. Easy fix. Grind or file the iron.

Thanks to all of you. It didn’t make sense the way it is now but I was afraid to touch it in case I made things worse. Can’t wait to get home to try it but work is needed so I can get more playthings later.

I agree the iron should fit easily, but keep in mind you really don’t need much lateral adjustment for a jack. Just make the iron fits easily in and out and you should be good.

Don,

I don’t know a lot about planes. If you say a jack doesn’t need much adjustment are you saying that other sizes need more adjustment? Why have it at all if the blade is ground and polished properly, the frog set correctly, etc?

A jack is used for course work and the blade is sharpened with a camber. Moving a camber from side to side Or laterally adjusting it) has no effect on the cutting action.

A smoother is sharpened square or close to square. When one side cuts to deep, you move the top of the cutter laterally which lines the square cutter with the sole of the plane.

A jointer would be like a smoother. If its not cutting square, laterally adjusting it will help.

So if I have a jack with out much lateral adjustment, I don’t really care.

If a blade is ground perfectly square to the sole, then you are correct, you wouldn’t need the adjustment. Keeping everything that in tune is difficult, its just easier to have adjustment.

Jeff-
Also because wood moves depending on moisture content. Many wooden planes I see have one side of the tool cracked. I think that this mostly comes from ham-handed hammer adjustments to set the blade edge square to the sole.
But I live in the desert and I also see plane irons stuck in wooden plane bodies even with the wedge removed. I think that that is from the plane body shrinking and holding the iron. I aim for a plane blade that has some side to side play with the wood body. I think that 1/16” is enough for the changes in moisture/humidity I experience here.

Thanks Chuck. I’ll be trying it out this weekend.

Have your say...
