Terry,
Ooo, ouch, that sounds like one dedicated hole for  a specific diameter 
circle drilled and tapped into the table top of  the saw. I dunno. I have 
used a simple jig consisting of a  length of 1 inch wood strip clamped to the 
table of my bandsaw or scroll saw. Put the center point anywhere you want it 
on the wood strip. I have cut circles out of aluminum, brass, HDPE and even 
G-10. McMaster-Carr sells a bandsaw blade with 4 TPI for
cutting G-10.

Happy day,
