Square bus wire looks good on 1920's radios but I have been reluctant to buy it commercially. I stumbled across a jewelers tool on Ebay called a draw plate. The square plates have a series of various sized square holes that are tapered in size from the front to the back of the plate. The price on Ebay ranges from $7.00 to $70.00 approximately. I went for the $7.00 version and the total outlay was less than $10.00 Cdn delivered to Ontario.

I started off with #12 house wire. The wire should be annealed, easily done with a propane torch. I tried both beeswax and oil as a lube. One end of the wire was ground down to get a start that could be held with vise grips. The draw plate is held in a vise and the wire pulled through it. The short piece was just a test. It was pulled three times through progressively smaller holes. Although I did not, annealing before each pull is a good idea as the wire stress hardens with each pull.

The wire looks better than in than photo, the flash accentuates the defects and shows the wire larger than it actually is.

That's a great idea!

Kerosene, WD40, cutting oil, and lard work as a good lube too. Be sure to clean it off the wire before using it though.

Olive oil works in many applications- food safe in case you have fun-loving critters about your hacienda...

Thanks for the descriptive photo. I could not figure out how to pull with two hands and take a picture too. The photo shows exactly how I did it. Did some four feet at a time, longer can be done.

The buss in my photo above is 0.0710 inches. I did more going one step further and got 0.068 inches. A piece of 1920's buss I have is 0.063 inches and the AES buss is 0.064 inches. Plenty of smaller holes to draw through, one step more may do it.

Good show, Ed. Thank you for posting this. Are you taking orders? :0)

"I have been reluctant to buy it commercially..." Can anyone here suggest commercial sources for Buss wire?

Was the size of radio Buss wire identified by gauge or dimensions?

Thank you.

Lou, "shape-wire" as wire that is not round is referred to in terms of square #12 awg would be measured across the flats to the same dimension as #12 round. So, that means the 'scribed square cross-section carries more current than the same wire size in round.

IMHO, I prefer #12 as the increased area and rigidity are good for TNT style transmitters where any vibration would modulate the signal.

Tks Chas. By gauge it is then. Your call and name are familiar. Are you a member of (Yahoo) AWAGroup?

Again, can anyone here suggest commercial sources for SQUARE Buss wire?

Thank you, Ed.

While not claiming to be the "final word" on 1920s square buss wire, from my experience the common buss of that day was 16 and 14 ga, dull tin finished and half hardened. I've looked for several years for that, but with no luck. Anyone know of a source of square buss wire as described?

Regards, Lou

Yes, One in the same.

I don't recall seeing any 16 ga, but 14 ga is more common. FWIK the 12 ga is from a New Jersey manufacturer. I had the address from some 35 years ago.

Try:

http://www.thomasnet.com/products/wire- ... 202-1.html

The same search should be applicable to Canada. Probably won't find a small distributor as there are no "hobby" users of such a product. A smaller company, based on sales, may put up 100# on two reels.

BTW the AES product is undervalued, it is almost at scrap price.

I've found the AES product to be too large and too soft for general purposes. Doesn't fit era terminals. etc. Re-extruding it might make it useful.

I have made much smaller square wire from the square stock I've on hand by grabbing one end of the wire in my vice and pulling with my vice grips on the other. I have stretched the wire almost half again as long as the piece I started with and it does harden some but it does keep its shape and finish very well. The result is good because if the original has kinks and bends the pull fixes all of that down to dead straight wire.

Very clever, Ed. I'll try it out. Thanks, Lou
