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?
