I did look at this and you give me (at least an implied) recomendation that it is accurate. I'm full of fear at actually drilling or cutting the body yet, so I was looking for every cross-referencing measurement I could find. I shall place my trust in the guitar gods....
And thanks for this link!! I've been building templates off FR Original specs, making mods where it seemed appropriate. Of course, 'schaller.com' is just an ad site.
Neck is all done, and body shape is cut, but I've been procrastinating anything further. Now, I'm running out of delays. The cutting soon will commence!
I have used the Stew Mac calculator before and it works but I always double check before I cut/drill. I usually use the actual bridge and a pair of veneer calipers to check measurements. If you don't have the actual bridge the schematic drawing should be your reference.
Good luck!
