I just bought a Stanley 78 hand plane and I noticed while tuning up the blade that the edge of the blade sticks out beyond the edge of the sole by about 1/16 th inch. Since this plane can be used to make dadoes I thought this might be a problem. Or since I do not know much about these planes it may be that it is intentional. For what purpose I do not know. The plane was purchased on eBay and is very old. Pictures of other planes like this show blade profiles exactly like mine (1 1/2 inch width). Any thoughts on this being a problem or just normal.
Regards,
Don
