Hi Clapper, I've put it to the barrels and it appears fine, I cannot see any difference gappage than prior to my CCH. However, I have to say I've only researched and gathered my data unscientifically. It's very interesing to read what you say about tolerances. I have to say also that I did crap my self the two times so far that I have dropped the parts into the water. Keep it coming!

Great info all round.
