I was thinking about playing around with the originals.... It's taken me about 16 to 20 hours just to get these ones to the point they are at..... The first can took the longest to get it right...the second was a lot quicker.. Just like most things are. The first time is always the hardest..Interesting, what you should do now is start fiddling with the stock cans, polish them, open up the insides a little bit, then make a new tip.
Took some skill to get those done right....
