I'm making up a kit of tools to carry with me on XC, and for general
purposes to work with a friendly A&P to accumulate A&P hours. So,
what sizes do I carry? the 1/4, 1/2, and 1 inch wrenches are a
given. As are probably the sizes in eighths. Are the sizes in
sixteenths worth carrying? How about the 32conds?

I am also considering making up two kits: a minimal one for XC
flights, and a "working with the A&P" kit that's more complete.

Yes, I can use my A&P's tools but I'd prefer to have my own handy
instead.

So, mechanics and experiences owners, what sizes are necessary?

Thanks,
Malcolm
