I got a low cost Tiger mast for my 18SX <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" /> but I have to reattach all of the hounds, tangs etc. I found a company that offers closed end blind rivets that are suppose to eliminate water seapage into the mast. My question is rather to use 1/4 or 3/8 inch long rivets. Any suggestions would be appreciated.
