Here's what I came up with that works for me so far.
Copy this script and save with the.esp extension......

N 30 is the division so change that as you wish.
Open it with PS as the default 8.5 by 11 document.
Use the Magic wand to select the outter ring and scale that as needed.
Save as needed and use it as a template for placeing stuff.
I can whack out those 30 bolts real quick now!!
