Dummy making a dummy load box
Tim88:
Well, a dummy compared to most here anyways :-DD. Found this neat design at Milletts site http://www.pmillett.com/dummyload.html. Got the heatsink drilled, tapped and resistors mounted. Quite a bit of work, more than I figgered but the worst is over. Got the resistors and heatsink from the links on Millett's site. The fancy box was a tad too salty for me so got a $10 one on the fleabay. Cut the top of the box out with my chop saw then dremmel the corners. Made a template on MS paint, taped it to the heatsink and punched the drill holes for reference. Used my drill press to sink the holes which I highly recommend using to get them true. I used some hardened #6 screws I had laying around which on retrospect, wish I got bigger ones but I am cheap |O. Used a hand tap, didn't have an end cutting tap in that size so ground the tip down. Working with aluminum can be tricky, gotta use tap oil so the tap doesn't bind. I am just going to set it up for 4Ω/8Ω and just use a double throw switch instead of Millet's fancy switches. Hopefully get her finished in the next day or two. Can post what materials and template if anyone wants.
