<< < (2/3) > >>

magicrat56:
last nite i was taking measurements in the air -horn and found the accell. discharge ports are drilled out to .039"! can this bushing be resized? if not i have one here. could you use a roll-pin punch to peen the face shut and redrill them? i'm determinded to get this one right! thanks again,joe 

Cliff Ruggles:
The holes can be carefully peened down some an re-sized.  We have also installed threaded brass set screws in them and re-drilled them, but only to save valuable/rare airhorns....Cliff

leroy:
Just on the Accel discharge holes in the air horn it is the hole that shoots into the barrels yeah?

 there is not a smaller hole that should be present within that passage?

The reason for asking is my  accel discharge pump holes are also huge and I wondered if I was missing something

Cliff Ruggles:
The actual restriction is in the second partition deeper in the casting, not the large outer hole....Cliff

leroy:
but still in the air horn yeah not the main body?
