Anyone know for sure the guitar sting sizes that fit a .25 and .35 nozzle? I found a #9 in the basement for decades ago and it measures .2 and does fit but did not remove the crud as it is smaller than the hole.
I am guessing the #10 is .01 and is .26mm?

You're better off just removing the nozzle and hitting it with a blow torch to burn all the crud out.... sticking anything through the nozzle could cause unnecessary wear.

This would be to use with the torch after removal. I have a machinist scope that lets me look right down in that tiny hole and see the stuff still within it.
Guess I will just take my caliper to the music store.
BTW, the nozzle fits a standard metric bolt (not sure of the size but had plenty in my assortment) If you remove the head of the bolt and spin a nut on, you can attach the nozzle and snug the nut against the nozzle and place it in a drill press. The with the press running on the lowest speed, polish the outside of the the nozzle lightly with 1000, 1500, 2000 3000 grit wet for a non stick surface. It also will remove burs and nicks from around the orifice. Obviously it is brass so go gentle it does not take much time to get nice and smooth surface.

Given the number of music wire gauges, that's the only way to be sure:

And, of course, guitar strings use different gauges:

The steel music wire coils I bought long ago don't bother with a gauge number. The boxes give the diameter in inches and my assortment goes all the way down to 20 mils = 0.508 mm; I never expected to need anything finer than that!
