Bits 'O This and That

Got the little speaker boxes glued together. Now I have to sand them, coat them with some 'bed liner' type stuff, put the foam in them, wire up the crossovers, yadda, yadda, yadda....

Probably would have been a whole lot easier to just get ready-made speakers, but I've never built a speaker before and thought it might be interesting.

And I bought new magnifying lamp for the workbench. This one has a bigger lens, 4 brightness levels, and 4 presets for color temperature selection. The other lamp is now clamped on the bench where the speaker and Commodore projects are currently residing. I'm trying to find a replacement fluorescent tube for it, as it's a good little lamp, but the tube is fading.


And I finally got around to gluing the busted coil back together for the Multiplex Board on the  Heathkit AR-15. Took a bit to figure out how to "fixture" it together so it would be stable while the glue dried. I ran a length of #18 tinned copper "Bus Wire" through the form and the tuning slug, and then clamped it in one of my little thingamabob holders. Worked like a champ, and after the glue on the one side had dried I can flip it 180* and glue the other side. Then I have to tin and solder the #40 wire from the winding back on to the correct lug. I'm just lucky this was a coil, and not a transformer with multiple windings, like an I.F. Transformer.


  1. Real speakers! Custom, to boot. That's a blast from the past and a good one with it. Blast away.

  2. Considering what a decent pair of ready-mades cost, and what I've got in these, my labor is working out to about $.15/hr!

  3. LOL, and the neighbors will start complaining in three...two... :-)

    1. Hey, I've only got 75 Watts/channel, and the whole shebang is in the basement.

      If the neighbors are complaining, then the wife must be really pi$$ed!


Keep it civil, please....

Fabulous Fall Day

 Some of the trees are showing signs of turning, but they're not in their Fall colors yet.  This is from two years ago. We have Bumper C...
