Dan
The best way is to contact Ray Allen, and speak to the boss there (I can't
remember his name now). He normally helps and he is obviously the best
expert on their products

SCRATCH THE PREVIOUS POST. I realized that your were
trying to integrate a third party actuator with
the Ray-Allen indicator. As I was revising my
posting, I accidently produced a set of keystrokes
that SENT the unfinished message.
Here's the REVISED POSTING that goes to your task . . .
Use your multimeter to find which of the two potentiometer
connections out of the actuator DO NOT CHANGE RESISTANCE as the
actuator moves. Use a battery to drive the motor while
watching the multimeter. These are the ENDS of the potentiometer.
Once identified, you need to know which wire is the EXTEND
end of the pot leaving the other one as RETRACT end
of the pot. Hook your multimeter to ONE of the ENDS
and to the third wire identified as NOT an END.
Drive the motor in RETRACT direction and watch the multimeter
for resistance reading. If the resistance reading
is going DOWN, then you're attached to the RETRACT
end. If the reading is going UP, then you're attached
to the EXTEND of the pot.
Now, you can take a copy of the drawing I posted at:
http://www.aeroelectric.com/PPS/Flight/Trim/PitchTrim.pdf
and mark up the schematic's ORN/GRN/BLU wires cited for
potentiometer leads in the actuator with the new colors
you've discovered during the experiment cited above.
Interestingly enough, connecting Ray-Allen colors to
extend/arm/retract colors you've deduced above still
leaves you with a 50/50 chance of getting it hooked up
right the first time. If the indicator reads backwards
from the true trim-up/trim-dn motion of the actuator,
you'll need to REVERSE THE END CONNECTIONS to the
actuator's position reporting potentiometer.
Obviously, this situation does not support the rant
on RAC contained in the previous posting.

Needed to visit the local Radio Shack for some aircraft quality
parts a few days ago . . . I browsed the tools rack and spotted
this thing.
http://aeroelectric.com/Pictures/Tools/Soldering/Battery_Portable/RadioShack_64-039.jpg
I've been using it on the workbench for several days and found
it to be a good value. It's not going to replace my Metcal solder
stations by any means but it's performance is entirely
adequate for most of what I need to do away from the workbench.
I've used a variety of gas powered tools:
http://aeroelectric.com/Pictures/Tools/Soldering/Gas_Tools/
and a few battery powered devices that I pitched before they
found their way into my toolbox. This $20 widget has some
impressive performance. Jury still out on cost of ownership
and general robustness.
If any of you try it out, let us know what you discover and
if you decide to pitch it, let us know why.

Ahh yes the HF stand up micro torch.
I loved that thing..Unfortunately I was also doing some Oxy-actelyne weldng on
the same bench and just the tip of the welding flame was impinging on the plastic
and well, the good thing is it only melted the plastic so it din't work any
more.
It was the best $5 I'd ever spent and I reall want another one..Trouble is I can't
get it for $5..:)

Thank you, Bob! I tried it and it worked like a charm!
