I saw a nice 'hatch' mechanism somewhere for that 'tank transit bracket'. You could reach in and unlatch it but some people often forget to unlatch for the live show apparently. I read somewhere that bracket was only in the first few runs but not sure. I'll add one of those FOR SURE. I was thinking of adding a light when the bracket is engaged. Apparent the foam rots/degrades and crumbles away too? Maybe leather instead of foam?
I'll keep the inside wood tone, maybe even unfinished...
That leads me to another question: Have you seen those metal 'ears' on some earlier builds? The metal seems like a different type than the chassis, and it seems to attach somehow to to the main chassis but I have not seen any pics for it at the right angle. I know the ears screw into the rear panel vertical posts. I'm guessing the chassis on more recent models and clones are secured only by those 2 bolts going through the top and faceplate? Maybe they figured that was secure enough and dropped the metal ears.
The baltic birch plywood one I built looks great on my bench with the baffle dry-fitted. Just waiting on my deep-purple tolex :)
The eastern white pine one I started needs better pine. The boards were slightly warped with small cracks. Not dried correctly. I plan on looking at premium pine boards this week and they should be the very best you can get. No knots, no cracks, no warping, tight grain, clear pattern and good supply. ( I'm at the doorstep of Algonquin Park in Ontario Canada and we have the really old/large pines here... I'm also trying to get my hands on some pine which has been submerged for over 100 years. Those logs were too big/heavy for loggers to float them down the river here, and they happen to be the best ones )
