<html> Corte, I use the Sciortino Insta-coiler often.  Joe Sciortino was a member of our Chapter here in Suffolk.  He was a friend to all PTG members, but took special pride in teaching beginning technicians.  He recently passed away, and is missed here by many.  I happen to have the original prototype of the Insta-coiler.  In fact, after many years of use, I've worn out the tuning pin piece, and retired it for posterity.  This original tool had about half the amount of metal below the string slot in the housing that fits over the tuning pin.  Because the supply house version has more material below the slot, the housing sometimes bottoms out on the plate and causes the coil to wind up on  itself.  I ground a bit of material off the bottom of the tool, and it works much better.  (Boy, a picture is worth...) Anyway, hope this helps.
