Its time to start making some sawdust!
Ripped and thickness planed some 1x8-inch red oak into 1.5-inch wide boards to be used as the lower case face frames.
Pre-stained the wood and drilled the pocket holes.
The bottom of the case was also drilled for pocket screws.
Face frames were assembled with some glue and screws.
A homemade depth gauge was fashioned from some rubber stoppers/bumpers.
The depth gauge was used to drill holes for #8 threaded inserts on the inside of the face frames. A hex driver made the task of screwing the inserts into the wood easy.
The lower case face frames and bottom all assembled.
