Hi, Ive been restoring old planes, and chisels for some time now… I consider myself ok at sharpening at best..

I just purchased a new veritas large shoulder plane. the blade is A2.

I use Diasharp Diamond plates.

Ive been lapping this blade for at least 2 hours tonight using xxcoarse (started with fine but was way offflat)

I used xfine to make that last pattern in the middle.

My question is, Is it possible that im doing something wrong? After all that time I am so far from getting this new blade flat…

Ive have better result with older blade (but I spent WAY more time on each)

I am doing something wrong or Its normal for a new blade that isnt pre-lapped to be that unflat?

Thanks 🙂

Ugo
