[Elecraft] a K2 thought?

[Stan Rife]

	That's the method I used as well, Craig. I would read the part, pick
it out of the labeled bin, verify the color code/part code/value with the
manual, insert, double check again between the manual and the board to make
sure things were as they should be and then move on to the next part. After
all the group was installed, I would solder everything. The best way I found
to check for bad/non-existent solder joints was while I was clipping the
leads. This all went quite a bit faster than it takes to talk about it. You
kind of get in to a rhythm and things progressed along well for me.

I stuck with their groups and even grouped others where it was more
efficient. Before soldering a group I reviewed each value and positively
confirmed the location and value of each part. After soldering I examined
each lead to make sure it was soldered well, and confirmed this as I trimmed
each lead. In short, I think it's possible to be just as careful but have
the efficiency of doing all the part placement at one time and all the
soldering at one time.

There are notable counterexamples, however. There were two or three places
in my K1 where it would have been SIGNIFICANTLY easier to install the parts
in a different order to make it easier to reach the part with the soldering
tip or to trim the lead.

This can't be said enough. I wear reading glasses during construction and
attach those clip-on magnifiers. They're wonderful and don't get in the way.
Even the writing on the smallest diode appears billboard sized and easy to
read.
