Message-ID: <[email-masked]>

I'm the one who's been bugging everyone about this and that wrt building a
50W CW TX.  Well, I've yet another question (just like an annoying child).

The TX is based on a tube (6LR8).  I plan on mounting everything on an
aluminum chassis with point to point wiring underneath, using tag strips and
the tube and relay sockets as anchor points.

I would like to use the chassis as the common or ground.  Rather than using
nuts, bolts and spikey spring washers, I would prefer to solder to common
returns to the chassis.  I believe I'll get a better, longer term connection
if this is possible (am I wrong?).

I have a 40W temp. controlled iron (Ungar) and a dirty great 140W Weller
soldering gun.  Is it reasonable/possible to solder the copper wire directly
to the aluminum chassis with one of these irons and get a good connection?

If this is not practical, has anyone any suggestions?  I can get a steel
chassis, but I'm a little reluctant to do this (cost and difficulty of
punching the many holes I'll need).

Thanks for putting up with me.

Cheers,
