I'm putting together my stall warning and it calls for enlarging two holes with a #31 drill bit - really???? Then I see the slot for the stall warning vane is made with a #10 bit. Does anyone know where I can get a #ed drill bit set?

Thanks,

Tom

We stock and sell all the #'d drill bits.

Don't do it

I couldn't figure out why the slot would need to be anywhere near #10 in width. I stopped at about #16 and I wish I had stopped at about #21. All we should need here is a slot wide enough to allow activation of the microswitch. At #10 we will need to put a screen on the hole to keep the sparrows out :)

Maybe I'm missing something, but I can't see it if I am.
