View Full Version : Krenov adjustment problem

I just built my 4th Krenov style plane. All my others worked great from the get go, but this one is giving me problems. Specifically, its a short-ish jointer ~17" maple with cocobolo sole. Works nicely, but I can't back the blade out no matter how hard I smack it. I can deepen, and make lateral adjustments with the same taps as on my other planes, but cannot adjust for a lighter cut without removing the wedge and starting over.

Any insights?

Gabriel,

Are you tapping on the heel of the plane or on the top back of the plane?
Also, what is the angle of the blade.

I see a difference of geometry when the heel is so far back and especially if the angle is steep. The tapping becomes close to a right angle to the blade instead of being close to in-line with the desired motion. Is there a safe place to tap the top side of the back half of the plane?

I've been tapping, actually TAPPING the tail. The blade is at 45. I figured it had something to do with the geometry. I suppose I'll give it a shot more on the top of the plane. I've yet to do any carving, perhaps I'll work a little ledge into the top.

I look at Steve Knight's wooden planes and they appear to have a tapping area on the top back of the tail. That would make sense if you want the energy to go at a 45 angle to the plane body (same as the blade).
