Classic RT rear frame hole size

[flaw101]

I'm wanting to put an Inteliframe on my classic RT. What size will I need to drill the rear frame hole for the banjo? 11/32" is the only thing I found in one thread in all of my searches. I want to be sure before I drill the frame.

Thanks

You'll find varying answers to this question, but I drill them with a Letter D drill 0.346"

Thank you very much.

Just start small and keep going up a step until the frame fits.

Biggest trick is making sure it stays nice and smooth so no Orings ever get nicked. I tend to bevel it a little on the frame so the Orings slide in to the frame smooth.
