“Bumpy” or Variable Depth Driver Chamber - Method?

Current plans take thre brace into account.
Hi Dave,

The Maeshowe plan for 15mm material does not show the baffle braces, and the first section of the horn is specified as 25.4mm. I do see the baffle braces in the 18mm plans, and the first section of the horn is specified as 28mm; larger, to account for the baffle braces made from 18mm material.

This leaves me wondering what to do, as I am using 15mm material.
 
What is the date on your drawing?
