Toothed Plane Blade

[Rob_Mc]

I recently bought a Lie Nielsen No62 Low Angle Jack Plane on Ebay which seemed a bit of a bargain;

When it arrived it came with the normal blade installed and a second new blade in its wrapper which turned out to be a toothed blade. I have a basic understanding that a toothed blade is meant for working difficult grain, but specifically what sort of woods and applications will it come in handy for? I am also assuming that toothed blades can be sharpened normally? I have a Tormek ... will the toothing of the blade dig in and damage the wheel given that the cutting edge faces into the direction of rotation when sharpening?

All guidance gratefully received.

Thanks,
Rob.

I found a toothed blade really useful when planing some yew, which had rather pretty swirling grain and pin knots. I was using a wooden toothing plane with the iron nearly vertical, but the advantage would still be there with your plane.

Sharpening a toothed iron is the same as a normal one - the teeth would only dig in if you presented the iron at entirely the wrong angle.

As would a normal (toothless) blade, as anyone with a fine soft sharpening stone can attest!

Toothed blade is normally sharpened a little differently. At least my toothed blades are. Don't know about the LN.

Maybe I am doing it wrong!

I've not needed to do any grinding so my toothed iron just got a rub over the oilstone.
I kept to the existing single bevel across the whole edge and of course you don't raise a burr or flatten the back!

Are there other differences?

Well you've just stated the difference, you don't flatten the back. I do pull it across a flat piece of wood to remove/burnish whatever may be there.

You can grind and hone the blade as normal but just draw the edge of the blade through a piece of wood to remove the burr.

Cheers :wink:

Sharpen it the same way as you would any other blade for the LAJ.

It is not for preparing the surface for glue when veneering, as a vertical toothing blade is for. The LN (and LV) versions are to aid in planing as preparation for smoothing when dealing with interlocked grain.
