I purchased a few dozen rods, but never used them. They came with a very detailed instruction sheet that said they could be mail ordered from the guy at this address: Robert Dunbar 453679 Creek Avenue Afton, OK 74331 I checked QRZ, and he doesn't appear to be any of the 7 "Robert Dunbar" hams on QRZ. You could invest 55 cents and mail to the address I showed. BTW, the instructions specifically recommended against your motor oil method. Instead, the work piece must be degreased. I also googled "Low Temperature Aluminum Repair Rod" and the first hit produced: aluminumrepair.com This site seems to be the motherlode for this stuff. They certainly talk a good game, just like the guy at Dayton did. The site owner is "New Technology Products" in Houston, FWIW. If you try these out, post your results, good or bad, on this reflector. Good luck! Rick N6RK _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
Re: Topband: Soldering aluminum coax shield to copper wire
Given the thickness of the foil and the likely surface treatment, I think soldering is going to be difficult. I've watched a TIG welding genius butt weld Coors aluminum cans (<0.004" thick) together. That might work. Maybe a spot weld ala a Si chip wire bonder. Grant KZ1W On 6/1/2020 19:42, Chuck Hutton wrote: Jim - Thanks. Of course one can use crimp connectors.

Sounds like his email account might have been compromised. I received one of these from him, too. Terry, change your password, and make it a secure one like this: https://blog.avast.com/strong-password-ideas Update Windows.
