While breaking down my Badger Xtreme Patriot 105 airbrush for deep cleaning, it became apparent to me that the original spring for the needle action was wearing out. It was impossible to reassemble properly as one end was stretched out of the original circumference, and was now fouling the cap of the needle tube. Hobbylinc came through with the right part, easily found and quickly delivered, putting my airbrush back to work with few days lost.
