Re: [BULK] - Poor soldering (was: Does build quality affect performance?)

[James Kern]

I think for people new to building and soldering the Elecraft article
on the website is definitely a good one on getting started. Reading
over that carefully is a good avenue to start. Still want to practice
some before you start a K1 or K2? Get a mini module kit and start
there.. that will get you used to soldering and if you really really
really screw it up, at worst it's only 20 or 30 dollars gone.

Perhaps the only sort of enhancement to the soldering instructional
information would be some small video clips showing a good joint and
some bad joints being made - this way someone can actually see the
process and watch how the solder is fed, how much etc. The difference
between reading about it and actually watching it done makes a big
difference. I learned years ago by watching my elmer solder the first
few connections of a keyer kit. When he let me take the iron, I already
had a pretty good idea of the 'motions' of soldering.

Also, you don't have to spend a fortune on an iron. Before I tackled
the K2 as my first real serious kit, I dug around on ebay and found an
inexpensive used weller soldering station with a tcp 700 tip. It was
pretty beat up, ugly, with a few burns here and there but it worked
fine. I think I paid a whopping $40 including shipping for the whole
setup and it works great. As reccommended by Elecraft, it certainly
makes a big difference in kit-building. After that I threw out most of
my cheap-o $7 soldering pencils except for maybe one or two that I keep
in a toolbox. Lastly, there are a number of places you can find some
good kester solder out there. I've still barely made a dent in the roll
that I have.

Just some food for thought..
