Beepster I can understand why you wouldn't want
to leave it with somebody you don't know.
The deal is- the nut is not something one should mess around with.
If you don't have a pretty good grasp and the right tools things could
go south very easily.
Now there may be some out there that can whip out a nut pretty quick...
but I think it's going to take some time to make one right.
With that said you should be able to schedule it to be done so you
wouldn't be without it long at all. I know if I were doing it you could drop
it off in the morning and pick it up after lunch.....
Now if he has his act together- when you pick it up he'll ask you to play it
and he'll be prepared to "finish" it up while you go to lunch...if he needs
to lower it a little more for you......so don't eat until after you go there LOL.
Good luck Beepster.
