I have seen similar topics discussed on this forum and those discussions didn't quite cover the thoughts and questions I have. Here is my issue. My second banjo build will be an Octagon pot Mountain banjo. While laying the plan out, I created a one inch grid pattern. I found that the best size where I get uniform edge lengths, was 10 3/4 top to bottom and side to side and 11 inches diagonally. Diagonally I get 4" flats and cross wise I get 5" flats and I'm happy with how this looks. I have decided to go with an 8" drum head size and this means that my pot wall thickness is top to bottom and side to side is 1 1/4" thick. Diagonally I get a pot wall thickness of 1 1/2" thick. So the question is how good will the resonance be with the pot being this thick ? I have considered reducing the middle section in size. There are three sections of 1" thick. If I reduce the middle section, leaving enough room for screws to hold the 3 sections together. I get a top to bottom and side to side measurement of 1/2" and a diagonal measurement of 3/4" wall thickness. So question two is what wall thickness will have the best sound and tone effect ? The top and bottom sections are of Red Oak and the middle section is of Dark Cherry. The bottom section will have a 4" sound hole that is stretched out to 6" by the points of the 8 pointed star I have drawn up. The neck is out of Dark Cherry with a Bloodwood fretboard. So the whole banjo should not only have a red color theme but also the wood used is known for good tonal qualities.

Ahoy Captain

Octagon pot mountain banjo I get -- But from there on I can't figure out what you are talking about. Sorry about that but maybe a drawing of something with some dimensions would help. Diagonally, cross wise, flats, top to bottom, side to side, oh my?

Side to side is where the neck is joined to the pot. Top to bottom is obviously at 90 degree angle to the side to side center line.
