The following design cost me hours of sleep. Part of my designs have accounted for inconsistent pins lengths, but now that I am using escutcheon pins, I should have similar size units each time. I measured a few, though some were different, but they were all close.
I drafted a pin, a magnet, a rectangular frame that could hold two nails in a straight line, and the magnet. I could quickly revise the design and cut new pieces with this design. I designed small clamps to attach to the side and hold rubber band segments across the top and bottom that gently push the pins into the magnet endcaps.
Rectangular frame and rubber band clips
I could not cut a hole across the top of the board with a 2-axis laser, so I etched the face lightly where I wanted a channel. The softened wood was easier to cut there. I clamped two pieces together and worked a drill bit between them, and it was a straight line. The drill bit was slightly larger than the escutcheon pin.
Drilling pin holes
I messed up a couple of the faces but refined the technique by scraping the etched channels before assembling them. I used a 1.5mm drill bit, but the pins were 1.3mm, which I feared would be a problem, but they still smoothly and kept aligned, so the long shaft worked.
Channels neatly carved
