Thread: Cutter angle for a 12-060 low angle block plane

I think the 21 deg reference is to the bed angle not the bevel angle. A 21 deg bevel would be rather fragile. I would put on a 25 degree bevel with a 2 deg microbevel using the Charlesworth ruler 'trick'. But it is important to make sure the sole is lapped and the back of the blade is too. The first makes sure the plane registers solidly on the work (esp the mouth - this is important for cutting properly) the second makes sure you get a really sharp edge when you sharpen (you only need to do it once per blade).

I have a Li-Nielsen low angle block. Came from the factory with 25 degrees, so that's the angle I've kept it.

Hi Scoobs,

Just spent most of yesterday sharpening the shed.

Here is jig that you may find helpful, I use a "eclipse 36"

Main bevel I set @ 25 degress with the secondary micro bevel @ 30 degrees.

A set of jigs certainly make life easier, make them out of any scrap you have lying around. If you use the top clamp (most plane blades) then a jig with the fence set at 30mm and another at 40mm will do and for the bottom clamp (chisels) 38mm and 50mm.

Guess you have plane like the one in the picture, those shavings are from the plane sharpened as described 25/30.

Have fun.

Cheers
Steve
