Side panels are made from solid walnut and routed out to fit over ends of chassis (pre-punched for easy mounting).
Walnut side panels attach with four machine screws & lockwashers (included) into metal inserts to avoid wood damage. Screws should not be torqued past 4.43 lbf.in ( 50 cN.m).
Usable surface of chassis front, back and top are reduced by roughly 7/8" (22 mm) due to inset in walnut sides.
Optional bottom plates are punched with 4 holes – 3/16" diameter.
