Finally figured out how I would get an accurate 1/16" chamfer on the edges of the splice plates.
Purchased a chamfer router bit, mounted it in the drillpress. Positioned the work table such that the correct 1/16" chamfer would be applied w/o having to lower the spindle.
Applied chamfer.
Measured bend angle tangents, bent new angles using vise, pipe, and hammer method. Had to adjust a bit on each of the parts to get the bend angles just right to ensure a flush fit.
