Unfortunately a 4x5 still eludes me. The size makes it difficult to engineer with the current design and due to this, I think the cost would be prohibitive for a quarter plate holder.
What I am working on now is a modification of current holders with a trapped door and spring style addition to the back side which would eliminate the need for 2 slides and loose springs. I'm still a ways off on this however. Getting component parts milled for the 8x10s has been the focus.
Thanks for the interest, Kal!
