Can you post a pick of your plywood+skewer set up please? Having a hard time picturing it.
Unfortunately setup is now at my Summer camp. Let's try a diagram
Below is a front, 'edge-on ' view of the carbide paper carrier..
xxxx is 1/8" plywood carbide paper carrier
_____ is carbide paper
I is about 3/8" piece of bamboo skewers inserted and glued vertically into plywood carrier

I cut the paper to carrier size. Punch holes at ends matching skewer location. Wet bottom of paper (as well as surface) with baby oil. Surface tension keeps paper stuck on carrier.
Assy replaces the stone. Obviously, with paper grit side down to abrade knife edge. Skewer stubs also provide a forward/backward stroke stop.
Ok?
