TWIT Tries Soldering Advice

[george graves]

When and why do you need silver solder?  And why the high temps?  Is the melting point unreachable with a standard iron?

I do airconditioning.........Silver soldering or silphos brazing, as the need arises. MAPP torch works up to a 10mm pipe, but bigger needs the oxy torch for the higher heat output. MAPP torch also makes a great fire starter, no need for firelighters, just a few minutes of ultra nuke and the fire burns well.

It was really meant as a joke, but in my case I used silver solder for making slot car chassis. They're made from piano wire and brass, silver solder bonds with the carbon steel and the brass.

I find the twit network a bit shite now. Too many ads. -Way- too many ads. Some shows take two and a half minutes to get going. But before I go onto my next paragraph, I wanna take a quick break...

And it's like a morning TV show, 60 minutes chit-chat and 5 minutes of what we might consider being some kind of content or a fragment of a piece of information.

PS: I take a box of red wine :-)

Seems to be a working show. Leo makes enough to keep on the air, and keep the doors open with it. There are some good sections, but I do miss Ray Maxwell, seems science and such does not really sell well, but the Maxwell's house episodes are very good, and worth listening or watching, if only for Ray teaching.
