trolling through some older posts i noticed this one. The Don Casey pop rivet method of securing a conduit in the mast looked like a difficult solution to implement.
I also fitted a PVC conduit into A-231's mast, but used a dollop of '5200 every 2 feet instead of the pop rivets mentioned above... a messy job but very easy to do. Has anyone else tried this method?
no problems with noise or chafe with any lines running internal to the mast (like the topping lift).
