The bridge.... I thought I'd try my hand at making a bridge plate from thin aluminum plate. I cut a few squares 3.75 x 3.75 and used a scratch awl and try square to layout some lines. I had these options for cutting out the corners and such. Hack saw, band saw, and notcher. I opted to use a hand held sheet metal notcher to notch out the corners and remove some hunks of metal in strategic places. I drilled some holes for the saddle screws and two holes to ease the corners in bending. More tomorrow.
