That also made for more flexibility in terms of component and wiring choices.
The new panels were made from .25" Baltic birch. A thin sheet of foam rubber was glued to the surfaces that contacted the interior baffle to eliminate vibration.
Next up was the tricky part, boring the baffles for the L Pad knobs. I made a cardboard template for the positions of the 4 mounting holes preserving, the original spacings.
The knob holes measured in at around 22mm, a large hole in a .75+ inch baffle. At a friends suggestion, a 7/8" Forstner drill bit was used for the task at hand. A few practice holes were drilled into some scrap wood prior to the real thing just to get a feel for things. That turned out to be time well spent, the holes are clean and straight!
