I was looking at the mechanism on my Macomber and have a question. There are some things that look sort of like jacks that are mounted just above the lams and attached only to the lams. What do these do exactly? If they weren't there, what would happen? The only thing I can see is that they keep the lams from falling out to the floor if no tie-up rods are in place, but they seem over-engineered if that is all they do. And actually, the side rods might do that anyway. . . .
So what are these for?
Thanks in advance.
