Jim,
You need to print this pattern big enough to fit...(Got to go measure...wait a min.)
Outside hole to outside hole (diameter) is minimum of 10 1/4 inches.
This board is about 10 3/4 tall by 12 inches wide
The holes need to be drilled with 1/8" drill bit.
I drill twice, once with 1/16" bit in case I'm off a little,
I can correct when I drill with the 1/8"
Here is other one again.
