Hi Karl,<br>
Did you make any fixtures to hold the pieces in place during
soldering? If not, could you send drawings, so I could think about
how to support them? <br>
I've had better luck soldering these type things on a hot
plate, rather than a torch. In my experience, heating it up and
doing all the soldering in one session is better than doing each
joint separately. I agree, a few test pieces would help. <br>
Thanks,<br>

That's what I assumed but I saw some blackening on the picture and
just wanted to check. <br>
<br>
We would like to do these, we are currently hung up on another job
availability will improve in the next couple of weeks. Are there
any extra pieces that we could practice on?<br>

The ones we've done here in GB were soldered with SN62.
There isn't much mechanical stress on these, so the softer
solder works fine. Also, the lower melting point allows you to
get on and off the heat quickly, avoiding damage/discoloration
to the gold-plated brass.<br>

Are these intended to be soldered with eutectic solder or
silver solder?<br>

and all, <br>
<br>
Rick suggested last fall that the Green Bank machine shop
could assist with fabrication of the new dipoles. We've run
into a snag and could use some help. The soldering expert in
our university machine shop has retired, and the current
staff have not been able to achieve the quality in the
soldering we need for the antennas (see attached). Would it
be possible for us to send the parts for the remaining 19
dipoles to Green Bank for soldering? <br>
