ajsons Posted December 7, 2005 Share Posted December 7, 2005 Dean, What material do you use for the mounting base? Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted December 7, 2005 Share Posted December 7, 2005 Dean, Those methods are all excellent ways to do it. I thought of the push connectors on the transformer pins early on but was always afraid a heavy-handed customer would break off the pins! I am tempted to ask UTC if they could supply the 3636 with actual pins just for that purpose! Wiring the common straps around the barrier block is very easy to do with flat braid. You just double over the end about 3/8 in back and puch a hole through it. A flat washer under the screw holds it. It bends any direction and lays flat to side of the barrier block. Al K.

Al Klappenberger Posted December 7, 2005 Share Posted December 7, 2005 Here's how you fold the end of the braid and make the screw hole. AL K. Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted December 7, 2005 Share Posted December 7, 2005 Here's the underside. The feet are rubber disks I got from a guy I found selling rubber sheets on eBay. He calls himself "Rubberman". You can get up with him by email at: rubbermann7@msn.com Al K. Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted December 7, 2005 Share Posted December 7, 2005 I'm mean about the big cables. I make my customers modify large spade lugs by bending the spade part down to a smaller (#6) screw size! It's really easy to do. Al K.

Deang Posted December 7, 2005 Author Share Posted December 7, 2005 Thanks Dee, I work hard on the silly things. Al, people I sell too use stuff like below. Isn't that braid impregnated with flux? I like it, but I can do things with the solid tinned stuff that won't work with the braid -- like feeding it through that little hole I drill on the autoformer and soldering it all down.That particular base is just hardwood. I had to use the thin stuff so I could use the stainless machine screws and nuts. The top layer of plywood crushes down and splits upwards when you bear down on it.

Al Klappenberger Posted December 7, 2005 Share Posted December 7, 2005 Dean, There is no flux on the braid. Getting it through that little hole might be a bit of a problem! I never solder to the briad. I just squash it under washers or those "L" shaped solder lugs. AL K. Quote Link to comment Share on other sites More sharing options...
jwc Posted December 7, 2005 Share Posted December 7, 2005 Al Where do you get your flat braids? I got my similar setup at my last haircut appt. No seriously, where? Mouser? Quote Link to comment Share on other sites More sharing options...
jwc Posted December 7, 2005 Share Posted December 7, 2005 I seem to have a hard time soldering the litz inductors well. The solder won't stick to it. Is there not enough heat on my cheapo solder gun? I don't have this problem with anything else. Quote Link to comment Share on other sites More sharing options...
Deang Posted December 7, 2005 Author Share Posted December 7, 2005 JC, you need to get all of the enamel off the wires. I guess you missed my post about it in the SAA thread. I use the soldering iron. Make sure the tip is clean when you start. Stretch out the lead, and then put something heavy on it a couple of inches back to stop it from moving around. Lay your tip on the end and rub back and forth -- you're going to melt it off. When you hit copper you will feel the tip scrape a bit -- start feeding solder. Stop for a second and clean your tip again. Back to the lead and keep feeding solder. I usually go until it starts dripping off and takes most of the enamel with it. Solder will not stick to the enamel, you know you're done when the quarter inch or so you've been working 'holds' the solder. You don't want a big glob on the end of the lead, so after you remove the iron give the lead a little flick with your finger to knock off the excess solder. Wear saftey glasses, and keep the kids away. Let it cool a couple of minutes and clean the end with alcohol. It took much longer to write this than it takes to do it.
