[Public-list] Chainplate knees and mast pad

[sousa, stephen (ENG)]

Peter,

I am not familiar with the methods other Albergs were built by Whitby. I
replaced my mast step a few years ago and during that time discovered that
the screws in the center of that step are attached to the support beam.
There are two bungs in the support beam which provided access to those
screws which are through bolted for removal. In my case #114 has the mast
centered over the main support beam. I would not have known this information
if it were not for this restoration work. Also I replace the chain plates
from 1965 with new plates made from 316 stainless and used the old chain
plates as backing plates.

Regards,
Stephen
#114

I didnt explain myself very clearly.The extra layers of mat would be on the
inside of the hull,also the plywood and chainplates. Only the bolt heads and
washers would appear on the outside of the hull. I have no criticism of the
engineering design of the original knees but the quality of their
construction leaves a lot to be desired.All of them on Tait Tait have gaps
between the top of the knee and the deck and a poor finish to to the
glasswork.George makes a good point about the bulkhead,I overlooked that
,but I could reinforce the hull either side of it and strengthen the
tabbing.The other options suggested are also worth considering.I may remove
the old knees and make new sturdier ones set so that the chainplates are
moved forward an inch.This would let me move the mast plate forward an inch
so that ithe mast sits more squarely on the beam.Any opinions on that idea?
