Routing a pickguard for a covered PAF - correct diameter bit?

CasperCaster

Hi all, I need to rout a pickguard for a covered PAF replica, and need a smaller diameter bit than I currently own. Can anyone advise what the radius of a PAF cover is at the corners? I'd like the the rout to be neat and close fitting. I'll make my own template, and will use the radius of the cutter to define the radius of the corners, hence I'd like to get as close as possible. It seems I can get either 1/4 inch or 3/16 inch bearing guided bits. Of course, both would be nice to have, but cash is a scarce commodity at the moment! Thanks in advance.

The collection of old pickup surrounds I have almost all match a 1/4" diameter drill bit not 3/16" - there are a few with a smaller radius, but none larger.

I did mine with a 1/4" diameter cutter. Pretty sure it was a trend one.

Thanks to all for your input. I was planning to order prior to receiving the pickup, but I think I'll hold fire until the pickup arrives and I can double check it.
