Bob

  I'm curious how you sweat soldered the fast-on tabs

to the bronze substrate- did you use electrical rosin

core or solid along with some flux?



Thank you,

Sam Ray

Hi Sam

I tinned the copper substrate that I used then pop rivetted the tabs on 

with steel pop rivets. Then heated the substrate with a torch. All with 

rosin core solder. Worked well.

   Electrical 63/37 with a synthetic rosin flux. Kester

   "44" is what I use around here the most. You can use

   any 60/40 or 63/37 solder with what ever flux gives

   you a good flow. Run the finished part through a cleaning

   with lacquer thinner (carburetor cleaner in a spray

   can) followed by a run through the dishwasher. This

   will remove all remnants of flux after the assembly

   is completed.

Bob,



Is it feasible to use a custom crimp tool positioner like 

(http://www.aeroelectric.com/articles/crmptool.pdf) to crimp the 

high-density d-sub pins (such as Garmin) using an inexpensive (B&C) 

crimp tool?

I used standard electrical rosin cored solder.  Lined the tabs up on the 
	


strip, and heated from the bottom with a pencil torch.  Touch the hole 

in the center of each tab till it fills with solder.  Takes less time to 

set up and solder a strip than it does to type this email.



If I had to do it over again, I'd just order from StenAir.  At a buck 

for a 10-gang unit, it's not worth the hassle of chasing down the 

materials and getting set up for the job to do my own.

   Interesting observation sir! I've always encouraged

   builders to be aware of the economics of their use

   of $time$. If the goal is to minimize the total cost

   of $time$ to get an airplane licensed and flying, then

   it makes sense to consider the make/buy decision when

   it comes to acquiring all the goodies needed to finish

   the project.

   I think I recall an gentleman at OSH telling me years

   ago that he would have been $time$ ahead to get a

   second job and pay a "pro" to build his airplane.

   Of course, he would would run the risk of

   knowing no more about the airplane than if he

   were flying a spam-can. Bottom line is that education

   is always expensive so the expenditure of

   $time$ has to be weighed against the perceived

   value of education and the pleasure of doing

   it yourself.

I'm with you guys on only making what is necessary-

these projects take way too long as it is!  I'm

building an RV8, which doesn't have a lot of firewall

space avaialable outside the forward baggage area,

that is also close to the battery, and stays clear of

the rudder pedals. I came up with a clever way to use

Bob's grounding system, but it requires making a

special single row of fast-on tabs.  I'll have 6

fast-on tab pairs, which will be plently since I can

rely on Bob's new Instrument Panel Ground using D-subs

to handle the bulk of the wires.  One of my design

goals is not to use the baggage compartments for

wiring and electrical systems overflow so I can have

maximum baggage space. Looks like I'll be able to pull

it off and also have a good grounding system.  Thank

you for your all your help!
