Hi James, You are certainly correct, good solder won't break, however, constant viberation, will stress the unsoldered wire above the solder. and even above the tinning. especially if the wire has been slightly nicked, or bent. Less movement of the core, (toroid) would keep that from happening. One wouldn't need to cover the coil, nor use more than one drop,
and what would it cause a problem with? Of course I am considering, more than simple walking vibration. Say for an example, carry the filter boards horizontally stored, in a box, even in foam, but set that on the back of... or in the saddle bag of a motorcycle. Run up the road for a couple hundred miles, and see if the viberation had an effect. Or, if the filter is stressed by a 5 G drop. I am speculating that the drop is not on the core... but on the board edge, thereby stressing all the "holding" wire to the ultimate. Is the stress going to cause a problem? Maybe? Maybe not. I don't want to be at the far end of a trip.. mountain run, or on the top of the mountain, after riding 10 miles up a narrow elk trail, next to the cliff that drops 600 feet, to find that the filter doesn't work now. And if one may use one to call for help.. I'd rather be safe, and work with a tiny bit of wax, that blows away under a hair dryer, or hot air gun. That's what I am getting at. I don't like glue, pv, sealer, or hot. or cold... glue has a poor record with me for this purpose. I can't get it outta the way when I need it gone. And it always seems to leave when needed the most. In other words, in this application, the glue has a poor repeatablility record for physical stress testing. Bees wax, or candle wax is exceptionally strong, and if the radio is going to be subjected to High temps, it may not be a real good alternative. However, I don't leave my radios in a closed car in the summer... (closed saddle bag, maybe, on a horse or a motorcycle) but then it won't find high heat there. not enough to melt the wax. One beware tho, don't use Partylite candles. they have a low temp wax. Gets soft in your hand. Not good. Old parafin works great. Thanks for listening, just my way of doing things.. I guess. --... ...-- Dale - WC7S in Wy > From: [email protected] > To: [email protected] > CC: [email protected] > Subject: RE: [Elecraft] hot glue K2 toroids? > Date: Mon, 2 Mar 2009 22:06:22 -0500 > > Dear Dale, > > Forgive me if I've missed previous email messages, but I still see no point > in securing the toroids with anything else other than solder??? > > Why can't one just solder them in properly?
