Re: Bevel-up plane with a buffed blade

Derek Cohen (in Perth, Australia)
Hi Winston

The surface looks great, as does the edge in the photo.

Assuming that you added 20 degrees to the 25 degree bevel, the final bevel would be around 45 degrees. Yes? Now you have to compare the results of just using a 45 degree micro bevel. Will you have the benefits of a low cutting angle on this soft wood? Or are you in actuality planing with a high cutting angle?

I will repeat a comment I made on SMS here for those interested in BU planes: generally I would use a 50 degree bevel for a 62 degree cutting angle for BU planes on West Australian hardwoods. At these levels, there does not appear to be any reason to add a Unicorn profile. It is six of one and half dozen of the other.

Regards from Perth
