Took a break from the brake to fabricate a couple of cord holders for the tool cabinet from a 2X2. Simple yet elegant.
Cut and sanded one side of form blocks for rudder ribs #3 and #4 which I had previously drawn on a piece of solid oak flooring left over from a job at work.
Needed to try out the brake on some actual parts so used Olfa knife to score a couple of standard angle blanks as shown on sheet 6-T-1 of plans (the "L=1219" specified corrresponds to the 4' width of an aluminum sheet). Used Larry Wingers Bend Line Spreadsheet to determine the developed length then bent using corresonding bend/sight line. Resulting part was bowed with variances in the "a" and "b" dimensions (> and < the 19mm specified); caused by inadequate clamping forced due to the top-to-bottom plate gap? Made a 2nd attempt using a strip that was much wider than the 35.78mm developed length - better clamping of a stiffer blank. Part was still slightly bowed but will easily straighten when riveted to mating parts. The 19mm sides were created using 1) right-handed tin snips and 2) Olfa knife and staight edge. Think I'll try another one using the inverted top plate (teepee) method.
