How about masking the substrate with protective film before cutting the
holes, and then bulk apply the glue (spray on, dipping tray, brush on,
etc.)? Apply balls, then press down entire finished piece with a rubber
mat between the marbles and press bed? Remove liner when done.

Thanks,
I think I'll try this approach first. I'll probably use a solenoid
instead of air. Electrical lines are easier to route and require less
additional equipment. I have already built and tested solenoid control
boards to control marbles from a parallel port.

In that case let's reframe the problem.

Take a 1/4" thick piece of hard felt.
Apply the same through-hole and domed countersink as the wood.
Keep it wet by capillary action with your thin adhesive of choice. If the
adhesive is too thick to wet through the back side, apply a dose to the
felt in between marbles with a dipped ball mounted

The transmission curve for glass doesn't permit UV. That wouldn't be a good

Edge cure grades might address that issue. They are specifically designed for

I can add if you need a free vacuum pump, a used fridge compressor will
do the trick. Just add some "vacuum tank" like an old gaz bottle or
something similar to get a reserve, as the fridge compressor is quite
slow, and it works well.

Another way you can do the glue application is to use a "glue

What if you used something that had like an annulus opening that the glue was
pumped through? Imagine two tubes one inside the other and the glue coming out
in the gap between the two. Maybe you could blow air through the center of the
inner tube to keep glue out of it and there fore off the bottom

You need to give some more detail on your adhesive. Lots of

or is in a syringe. I'm not sure I have a clear idea of what
