Some years ago, a friend of mine, homebuilt an a class cat, we sleeved a carbon fibre tip onto the aluminium mast at the hounds, this was however permanently in place (riveted) and incorporated the hound fitting. But there was no problem with it at all, performed very well. An idea at the time was to make a three piece mast one join at the spreaders, one at the hounds. But the only reason for the idea was because of the length of the mould we had made.
