AndyMech Posted March 9, 2014 Share #1 Posted March 9, 2014 I'm currently in progress building the main mast for the Mamoli USS Constitution cross section kit, and have a question. This may apply to a lot of ships and kits, so I'll post it here rather than my build log. The mast is made from 3 sections - pretty standard: the lower mast, top mast and upper mast/pole. What I don't understand is what keeps the top mast and the upper mast in place? For example, the top mast goes through the fighting top, between the trestle trees. Yet, in the plans, the lower mast diameter is 6mm and the trestle trees should be 6mm apart ,but the top mast is only 5mm in diameter. The bibbs that support the fighting top are also 6mm apart (as they are attached to the lower mast), so they line up with the trestle trees. The top mast fits between them as it goes through the fighting top, and then continues upward through the mast cap, but is too skinny to glue to the bibbs or the trestle trees. It doesn't seem that the mast cap would provide enough support for the entire top mast, which also supports the topgallant (upper mast/pole). I assume the mast cap is primarily for alignment of the mast - to keep it straight? Then what supports it against the weight of all the yards/sails/etc.? The Mamoli kit plans show nothing on how this is to be supported. I looked up the plans for the Syren, and it uses a "FIB" - a dowel of sorts that is drilled through the top mast and rests on the trestle trees. Should I install a FIB for my Constitution? Andy.
