hi again.

looking for technical advice.

I have an acrylic sheet 1/8 in thick, approx 16 x 20 inches, that was extra from my ginza vintage machine.

I need to take 1/8 inch off the long dimension, to fit the nishijin or maruhon machine, since they are slightly narrower.

how would you do this?

I have a couple ideas, but I thought you guys might have some better ones.
