Dear List ...

I'm rebuilding my static system and am looking for "how did you do it" 

suggestions.



Specifically:

How did you attach the tubing to the Van's static port rivet tails?

Glue, RTV or ... ?



Did any of you find a clamp that would work with such a small diameter and 

short rivet tail?



What method does not work or will not hold together between condition 

inspections?

Thanks, Jerry

Hey Jerry C

  

 I bought some rivets with the same head but a longer grip and used a little sealant and a zip tie.  I didn't like that the vans rivets had such a short shank to clamp to.

RV's Builders,  I used a silicone and the rivets in  the kit from Van's.  Is there any problem with using silicone on the  aluminum skin or ribs?  Silicone works well for holding parts in  place, however, will it effect the skin over time?  Thanks for any  input.

Hi Jim,

        Just do not get it on the outside where the paint will go.

It won't  necessarily affect the skins, but if you use it externally it'll likely make it  near to impossible to ever get a paint job to stick to it...even with it visibly  cleaned.  Silicone (or an product with silicone in it) is a  big no-no for external use on airplanes as it doesn't play nicely with  paint.

  

 Cheers,

 Stein

Not sure if they still sell them, but Cleveland tool makes some machined static ports which are very nice.  Just be sure and mount them to the OUTSIDE of the skin...otherwise the static port will be caught in the boundary layer, and will not be accurate..ask me how I know....

There are numerous paintable sealant/adhesives that can do the  same kind of job as the silicone-based ones. Proseal-like tank sealants, Lexel  and Sikaflex come to mind.

Well ...... depends.  Some silicone caulk smells like vinegar .... 

acetic acid ..... which surely isn't friendly to aluminum ..... but 

unlike the lead pencil/aluminum corrosion I haven't heard of any real 

problems with using silicone on aluminum.  In fact, I see it used quite 

a lot.  I know I didn't answer your question, but it is something to 

think about.

Stein,  Thanks for the info.  I appreciate your  knowledge, I'm sorry I didn't get to your shop last Saturday.   I hope  you had a good turn out and that your business is busy.  Good luck in  2009.

I came up with a way to make a back-side fitting for

Van's static port. This permits use of a removable

fitting for plastic tubing to connect the static vent

plumbing. It's described in the EAA chapter 105

newsletter for April 2005, page 2:

Hi Mike,

You have won the prize for an elegant solution to the static system plumbing 

challenge.  That's a clever approach.   If it's OK I am going to use it for 

my static hook-up.  It also seems possible to drill a close fitting hole in 

a light weight pipe cap, and expand the rivet into that cap then drive out 

the center stem.  Back it up with a little tank sealant.

Thanks, Jerry

I had the same trouble with the rivet tail being to short.  I went to the hardware store and bought some aluminum tubing that would just fit over the rivet tail before it was installed.  I cut about a 1 inch length and had someone hold the tubing over the rivet on the inside of the fuselage while I pulled the rivet from the out side.  As the pop rivet expanded it did the same to the tubing and the tubing made a nice little nipple to connect van's plastic tubing to on the inside.  I sealed it with a couple of turns of safety wire.

Hi Jerry



That's a good idea: It eliminates the tapping operation.

Also, one complication of my use of round bar is that

there are not features for use of a wrench. Vise grip

pliers solved that, but I made later versions from 1/2"

hex aluminum bar. Pipe caps generally have features

that make them compatible with some kind of wrench or

pliers. McMaster sells an aluminum cap that's threaded

for 1/8 pipe, their part number 44705K372, $2.18.

Mike,

Thanks for the McMaster part number on the cap.  I just ordered two of them 

along with enough "push to connect" parts to assemble the static plumbing. 

You are right, Mike, these parts will make rebuilding the system far easier 

and the sealing of small parts is now going to be a non-issue.

One other thing to add:  If a push to connect T is installed in the static 

line leading to the instruments, the transponder check will be simple to do. 

This T could be permanently installed in the line passing through the rear 

cockpit which makes it accessible while standing on the ground and reaching 

over the canopy rail.

Thanks,  Jerry
