[Public-List] Small addition to Mike Lehman's mast beam comments

[Daniel Sternglass]

Hello,

One small additional comment to Mike's excellent explanation of the mast 
beam reinforcement... When we made this repair in the early 1990s, I was 
told to make sure that there is _at_ _least_ _1/8"_ _clearance_ between 
the upper edge of the plates and the cabin-top, so that that the edge of 
the brace will not crack or stress the deck during the flexing that 
occurs in normal use. We were lucky at the time to work with a machinist 
who MIG-welded us a 3/16" stainless U-section brace.

Also, Mike's comment about replacing the chain plate bolts with 5/16" 
shank bolts is very important. When we did that, a number of the 
original "bolts" were bent significantly.

Thanks,

--Dan  S.
