[Elecraft] Re: Elecraft Digest, Vol 13, Issue 5 ---- SWING ARM MAGNIFIERS

[Wa6bfh at aol.com]

Be cautious with the “Swing Arm Magnifiers” (or even visor  magnifiers)!
 
I build a lot of proto-types, so I am not only soldering, but also  doing a 
board layout (as well as possible) at the same time (on the fly). This  makes 
for a lot of concentration and ‘focus’ (HiHi)!
 
As my eyesight gets poorer (and older -- life begins at 40 my ass!)  I find 
that the instantaneous puff of rosin smoke at each solder pad connection  makes 
my eyes instantaneously re-focus. This repeated and magnified change of  eye 
focus can give you some awful and whopping head aches!
 
I have best mitigated this problem by controlling the speed and  direction of 
a ventilating fan. This way, I’m not breathing lead and solder  fumes, and I 
can minimize the puff of smoke eye focus problem!

For the chap in Fresno -- visit M2 Antennas!  You can get some good VHF beams 
and other hardware, when you get your  transverters!
