John I only wanted 10 lugs on there just to have more lugs on there...festooned with lugs as it were. Haha. Looks cooler...but these rods have to be pulled toward the shell by the center posts or else they'd rattle in the posts themselves, that's my theory anyway. Point is the posts do put a bow in the rod, so changing heads is kind of a pain, rods don't spin freely, so...the less lugs the better. Not that I considered 6 heh. The center-post footprint is a half-inch cylinder, minimal interference with the shell.
Randy thanks man. I have to re-size the pic of the skin coiled into itself, it's so pathetic! Now *there* was a moment I wished I'd been a little more afraid of trying this lol. Ultimately though the original construction method, while not duplicated, dictated the re-construction method, at least for someone who can't fabricate forms. Couldn't be happier I did it, at this point.
So of course there's no "8.6 inches" - I went with 8 5/8", which was a tick too generous; final two rods [bottom] ended up closer than the rest by maybe a half-inch. So I fudged it a bit, and now it's fine.
Today I stripped and finished the drum. The mahogany is amazing. I won't cheat it with a low light picture right now, but tomorrow when there's sunlight...
