Posted: Wed Apr 11, 2007 11:49 am Post subject: Stall Warning - Dimpling nutplate holes in QB rib

I'm stumped.  I'm trying to dimple 4 holes in  a wing rib for the 

nutplates that hold the  the stall warning micro switch.  None of my 

yokes will reach the holes in the QB wing



I noticed that the SB wing builders are mounting the microswitch before 

assembling the wing.  Has anyone been successful dimpling these holes on 

a QB?



I know there is a wide neck yoke that  accepts dimpling dies that will 

work but $100+ says find another solution.

Couldn't you use a pop rivet dimpler.

I used the dimpling kit for tight spaces that came with my tool kit. It uses the pop rivet puller to pull the dies together on a shaft. (not a very good explanation, I am afraid)

I'll answer my own question here... I think I need a wide neck yoke.  I 

already have one but it is a thin nose yoke doesn't accept dimpling 

dies.  Since I'm done with the tail feathers, I'm thinking that I can 

try to have a friend with a mill, drill a hole in the yoke to accept the 

die.



I'm still curious whether others have run into this.  Mounting the stall 

warning switch is a job best done before wing assembly.  Even though the 

manual has this step done long after assembly, I noticed that at least  

2 builders (Deems & ?) did the dimpling before assembly.  For the QB, it 

would best be done during QB assembly.



Oh well

I don't recommend installing it until the wings are final-installed on the

plane.  That little tab sticking out is a great thing to catch stuff on and

setting it down on the leading edge once make the stall warning system

useless (although some on here would argue that is it useless to start

with).  Even when it is installed it is in a terrible location and easy to

lean on when fueling (ask me how many times I have done that).  I would

recommend installing it and rigging it and then taking it off and putting it

away until you are just about ready to fly.  The nutplates can be a pain,

but if you have assembled it once, then it should be a little easier and you

will know it will fit.

For one of my larger sizes, I have a die (Male) with the correct size hole 

in it.  A nutplate goes behind (I built one on an aluminum stick) and the 

die is tightened on the nutplate with an allen head screw...works fine.....

Would a pop rivit dimple die work? good for tight spaces.

I used the poprivet dimpler which came with the Avery Toolkit. Worked fine, no issues at all.

Of course, a popt rivet dimpler would work fine.  Not only that, I have 

one and have used it.  That's what I get for trying to work on 3 hours 

of sleep.  I knew there was an answer but just couldn't compute. 



Thanks to all who pointed to the solution.  I like the die mod that 

would permit taping the die to the yoke.  That would work too.  For the 

slow builders, it's smart to do the dimpling and fitting before assembly 

but leaving the final installation of the stall warning system until 

call for in the plans.



I got a good night's sleep and ready to go now.
