Still contemplating the next move on the needles from the States. I'm a little concerned with the diameter of the needle just below the viton tip. Does anybody know how the tip is attatched? I would assume they are pushed into the brass, I doubt they would be glued somehow.I'm looking to have to remove about 1/2mm from this end of the needle and the length of the needle. I have asked the seller if he could post me one to see if I can manage the modifications. See what comes out of that
