Everything wears out and needs repair kits.
Take myself for instance....
True, entropy wears everything down. I'm a bit odd. Can know and accept something, yet still not like it. I can also know other things running counter to what it is I'm needing to accept. Take the post below for example. It offers me a bit of a solution as stainless offers better resistance to oxidation. I know it'll wear out eventually. That eventuality's goal posts get pushed further along by using the solution, gives better durability. Better durability gives us better value for like some frugal tight asses we might know.
I forget which size it is,but someone figured out a while back that a Fat Daddy squonk pin will work as a 510 pin in the cv.I think it is the 2.5mm that they said worked,just have to grind or file the head down some.
Edit-I just pulled mine apart to check,and it is the 2.5mm pins that fit.You have to grind quite a bit of the head off to make it correct,but well worth the effort,as you will now have a nice stainless 510 pin instead of that whatever cheap metal they use,i think they use plated brass in the original pin.
Ah ha. Knew it would come back around if it had been around before. Keeping up with various threads, forums can at times find a person missing, or only half seeing something.
I had read something about I thought, the long needles of the needle tip bottles going up through the 510 pin. Stepped away before seeing all of it, lost the thread.
Do see how a FD 510 would work. Also can see needing to file it a bit. I can manage that. Had to file out the holes on the ChiNarda. Still didn't completely fix the whistling. Did figure out, don't use the inner air holes, turn the cap sideways and get no whistle.
That'll work, danka, gracious, thank you, spaceba. I'll now need to see if I got a few 2.5mm FD pins left over, if not I'll order some a bit later. At least now I know and that's half of it.
