Original question was about Hock blades in STANLEY made planes, if I recall correctly.
have had one such set up come through the shop one time. A friend was having trouble getting it to work.....
Underneath the frog, someone had set a metal plate for the frog to somehow sit on....didn't work, removed plate and tossed it away. Frog sat right down and stayed put, no issues.
Frog was too far forward....to the point anything over 3 microns thick would jam up in the plane. Moved frog back to it's normal setting.....no more clogs.
Yoke has having issues with reaching through the iron, to engage the slot in the chipbreaker. May need a plane hammer to adjust on the fly, after the setting is set up..
We even tried a normal Stanley iron and chipbreaker, taken from one of my planes.....no issues found, no "chatter" heard, could take as thin of a shaving as he wanted.
Placed the Hock back into the plane...worked fine, no clogging the mouth. Asked him why it was set so far forward...said it was the way he was told to do it....
Wished him luck, and sent them on their way. Did NOT need the mouth on the plane filed....just the frog was worked on.
The Hocks will work...IF the plane is set up correctly....most times, the iron costs more than the plane it is going into.....
