Has anybody tried using cherry max rivets for those impossible to get to rivets in a vickers water jacket ? We use them in aviation and they form a tight seal and are not hollow and weak like the pop rivets. Plus they have a solid round head when pulled. Although they are made from aluminum they are strong enough for aircraft so should be strong enough for a vickers. A small dab of paint could hide the aluminum color of them. I was thinking of using them for my vickers builds- just for the water jacket rivets, solids for the rest.
