[Elecraft] Suggestions, tips and ideas needed

[M. Hendricks]

Hello all,

I've had K2 S/N: 3464 in storage and I'm about to
begin construction.  I'll be using a Weller WESD51
soldering station with Kester SN63PB37 @ .031 diameter
and Kester SN60PB40 @ .031 diameter solder.  The
WESD51 uses ET series tips.  Any suggestions on tip
styles?

My understanding is that the 63/37 solder flows a
little better when soldering plated through holes on
double sided trace boards.  Is this correct?  Both
types of solder are Kester 44 rosin core.  If anyone
from Elecraft is monitoring this post, would my use of
the above 2 styles of solder have any negative impact
on my remaining (if any) warranty?

What is the recommended tip temperature for using the
above solder on the K2?

I also purchased the KAF2, KNB2 and KSB2 along with
the pre-wound toroids from AA3WF in PA.  Should I
completely assemble and align the K2 before adding the
options or add options as I assemble the K2?

Have any real significant improvements been made to
the     K2 kit since S/N: 3464, purchased in May 2003?

Thanks for your input,
MWH
