Hi   

The pix of the alternative way to mount the POS 12 are great! I am mounting mine Monday so it was very timely indeed.   

Which brings me to another question. I have some shielded 3 and 2 connector wire to attach my trim servos. Do I ground the shield by soldering a wire to it and then attaching it to a ground block? If not, what how do I handle the shield.  

Next question - I plan to run my tail strobe wires along with the trim servo wires. Will this be a problem or will the shielded trim servo wire handle things adequately or is it even a concern?  

Inquiring minds need to know

     The 'professional' way would be to push the braid back the length     you need to put a lug on the end and attach to ground screw.  Use an     ice pick or similer to open a hole in the braid and fish the wires     through the hole.  Try not to break any of the braid wires.  It's     easier if you fold the wire back on itself and then fish the wire     through.  Gets easier with practice.  Use a piece of heat shrink to     cover where the wires exit the shield.  I think there's an EAA video     on this method.

     As with most things .... depends.  Shouldn't be a problem.  The     equipment manufacturer(s) should recommend whether to ground the     shield(s) at one or both ends.

Hi Linn

  

 Thanks for the info. For other who may be interested, under  the ELECTRICAL tab on the http://www.eaa.org/video/homebuilders.html website  is a video called STRIPPING MIL SPEC wiring. You have to scroll down to get to  the video. It illustrates the technique very clearly.

  

 Cheers

  

 Les

Hey Les,

  

 Thanks for the link.  This is the first time  I've seen this source of information, and it looks like it will be good for a  few hours of wintertime obsessing!  

  

 Although the video is great for releasing wires  from shielded cable, I was also hoping it would address the original question of  how to strip those seemingly hair thin wires without damaging the wires.   So far, I've just been very careful with a blade -- with mixed  results.  I think I've seen some guys just pull the insulation off with  fingernails?

  

 Later, - Lew

     You can buy good 'automatic' strippers, but also get the blades for     real small wire sizes.

     

     If you use a single-edged razor blade with a little pressure and     roll the wire while cutting the insulation and a little practice,     you can strip wires easily.  

     

     You can also bend the wire, press the razor blade to the insulation     and you'll see the insulation separate.  Do not let the razor blade     'saw' against the conductor.  Works great on larger wires like coax.

     I doubt that the new Tefzel insulation will give up to a     fingernail.  The old telephone wire could be stripped with     fingernails, but that's the only example I have.  Some folks have     fingernails that are really thick and hard, so I wouldn't say it     didn't happen.

     

     The Tefzel insulation is also so slippery that it's hard to pull it     off the conductor.  If you get a rubber boot for a large alligator     clip, insert the wire in the small hole end, pinch with your fingers     and pull, it'll come right off.  I haven't been able to figure out     why, but it works so I use it.

Lew, Just take a wire about 6" long, like the piano wire which goes through the cowl pins, put it to the grinder and make a point.  Then use a deburring wheel and polish it up and remove the "sharp" point.  You'll find it works perfectly.

Hi Linn

  

 A small but perhaps important question. What kind of lug do  you attach? Crimp on ring terminal?

  

 Cheers

     Usually.  I put a little (1/2") heat shrink on the braid, crimp the     terminal, and then do the shrinking.  Don't cheap out on the crimp     connectors, and use a good crimper.  

     Hammers and vice grips don't hack it.  Not saying you'd do that, but     you'd be surprised how many do.

Another method for the ray allen servo wires for those that might not have seen it http://www.aeroelectric.com/articles/macservo/macservo.html   With the E6000 and heat shrink it provides very effective strain relief.  If you go to the trouble of trimming the db-9 connectors metal shells the whole assembly is very lite.

Hi Ben

  

 I have done this for one of my rudder trim servo and POS12  flap position indicator. 'Lectric Bob's method was easy enough to do. I also  mounted a CPC 9 pin connector on my elevator tim bracket for that servo. I  borrowed this idea from another builders site ( I can't remember whose). I like  the CPC in that loaction as it is easy to install / remove the  connection.

  

 Cheers
