I have a couple wooden planes (jointer and jack) I made using the cross-pin method. They’ve always worked spectacularly as single iron planes. The ONLY problem with them is that occasionally when grain reverses on me on the face of the board I can get some wicked splintering tear out (more than you would want to remove with a smoother). After learning all kinds of techniques to minimize it, it can still rear it’s ugly head. So I decided recently I would convert them to double irons. I started with the jointer. I took out a recess in the bed to accommodate the screw, made a thinner wedge (since the chip-breaker adds thickness obviously), and I made a little recess on the back of the new wedge to accommodate the tiny bit of screw that sticks through the chipbreaker. I’ve gotten everything to the point of testing before I go for visual aesthetics. Everything works PERFECTLY, with one MAJOR problem.
The problem is that when I advance the iron with my hammer, the chip-breaker winds up sliding back. I’m not exactly sure how to fix this. I rubbed some rosin on the underside of the chip-breaker which helped, but it’s still impossible to advance the iron without increasing the distance between the chip-breaker and the edge of the iron. I have ruled out everything else. It’s only when I advance the iron with the hammer. Obviously, I know from a physics standpoint why this is happening. I just don’t know how to fix it. Obviously there are double iron woodies, but I’ve never used a wooden bench plane other than the two that I made. So I’m not sure how they get around this problem.
Any advice greatly appreciated. I did prepare the chip-breaker and like I said, the plane cuts great. The only issue is the advancing the iron without the chip-breaker sliding back.
EDIT: just a point of clarification. When I advance the iron, the iron goes forward, but the chip-breaker does not advance with it (it advances a little bit, but it does not keep up with the iron).
