[Mg-t] Gas line replacement

[David Lodge]

Hello Clive and all,
I find this interesting because on the TC it would seem that all brass to
copper joints are brazed, e.g. carb overflow pipes, oil line from block to
head, lines to and from filter, etc.  Explanation?
Regards, Lodge, TC 1704, in dreary Vancouver

> You can braze, but the silve solder has a lower melt point than brazing rod
and you are less likely to melt the end fittings.
Since brazing requires heating the surrounding metal to a temperature that
will melt a brass brazing rod, the brass nipple will melt at the same
temperature.  This is a case where silver solder would be the material of
choice (I have always used straight plumbing grad soft solder and have never
had a problem.

fitting the nipples!

Now who would ever be dumb enough to forget that :-[

Kind of reminds me of the job I had back in the dark ages right after I got
out of the Navy assembling electronic photo flash units.  These were the big
studio units that used Amphenol connectors to attach the lights to the power
supply.  Said connectors had a screw on ring to secure the plugs in the
sockets and I was forever getting the connectors completely soldered and
assembled, only to find the securing ring still on the bench.  I finally made
a concerted effort to always remember to slide the ring into place BEFORE
soldering the wires in place and assembling the plugs.  After much work and
concentration on my part, I got it right every time I assembled the plugs,
only to have the boss come around a bit later and say, "you know, those
securing rings are really not necessary on thee plugs, just leave them off
from now on" :'(
Cheers - Dave
