Bob & Barry,

  

 Thanks for your suggestions.  I'm at the very beginning of the wiring phase, so the savings of Bob's suggestion covers the cost of a decent solder gun.  Will Radio Shack sell the silver solder?

  

 As to the ground, I plan on running all my grounds back into the fuselage to a common ground. The Glastar is a neat bird, but the metal wings (that fold) comming back to a powder coated steel tube cage and composite fuselage seems to me to be a good case for keeping all the grounds together.

Call a couple of Air Conditioning Supply Shops (HVAC), see if they have 6% 

Silver Solder or better.  I would not use just the soldering, a good round crimp 

terminal followed by silver solder should do the job.  BUT!  Remember, 

maintenance down the road will be a bit more difficult if you solder.

   How so? The pitot tube is supplied with pins that mate

   with an expensive, hard to find connector. The suggested

   modification allows use of inexpensive connector technology

   located remotely from the hostile environment located at

   the base of the pitot tube.



   I don't see that future maintenance is affected in any

   adverse way.

    You're looking for "hard" silver solder. Electronic tin/lead

    solder that bears some silver (2 - 4%) is not suitable Further, the

    suggested solder melts at orange temperatures. Conventional

    electronic soldering tools will not produce the necessary heat.



    My favorite shop tool for applying the necessary heat is

    a $10 torch from Bernzomatic. See:



http://www.aeroelectric.com/Pictures/Tools/Soldering/ST100T_Microtorch_small.jpg



    You get these at Lowe's, Home Depot, etc.



    You can get a kit of solder and flux off ebay

    at item  250006585548 or item 4463571008



    Practice with the tools and materials on sticking

    things together. Use some coat-hangar wire to emulate

    your pitot tube pin. Attach some pieces of Teflon

    14AWG to hangar wire until you're familar with the

    techniques.

    You got it. Local grounding is useful ONLY in metal

    airplanes assembled with lots of rivets. One you

    ad joints (moving or adhesive), all electrical bets

    are off.

=====================================

Bob:



It is not a big deal if the connections are soldered in addition to push on 

connections.  But, think of it this way; which would be easier for you to do 

inspect and do maintenance on ... A circuit board or component or wires that 

MUST be unsoldered from a circuit board to work on, or an entire circuit board or 

component or wires that can be moved to the workbench to be worked on, or in 

this case moved out of the way?



It is purely one's preference, the plane will not fall out of the sky.

I did say a "bit more difficult", not impossible.  Been there, done that, 

doing it now.
