I was recently inspired by the fantastic website of
K7QO to try to do something to improve my PCB enclosure building, both from an efficiency perspective as well as from a neatness point of view.
I built a fixture in accordance with Chuck's directions on
building enclosures and it turned out very well. Last night I was able to test solder together two sides using a piece of 24AWG insulated wire to ensure that the angle was 90 degrees once the solder dried (see pics below). I used a 30W Weller iron. I found that the technique worked better by having the vertical piece of PCB mating directly with the bottom of the fixture and in front of the 24AWG wire.

| Enclosure Fixture as per K7QO. The walls are a bit high. A lot of time was spent ensuring that the corner consisted of all 90 degree angles. |
Much as I would love to own a shear I found that I could accurately cut PCB's to exact size using my table saw. More on that later when I get to build a prototype enclosure as the next step.
Thanks to Chuck for sharing his extensive knowledge with us.
