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.....

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.
