[Alberg30] Forward Chainplates

[George Dinwiddie]

It's been a couple years since I recaulked the chainplates with 
Rule Elastomeric, and so far it still seems to be holding.  I did
remove the chainplates and burnish the surfaces with those little
round 3M scrubbers that fit in the drill.  This gave me a clean
surface for bonding.

As for the number of bolts, I know that Bruce Rankin preferred 
using five 1/4" bolts rather than three 5/16" ones.  He said the
strength was the same, though.  I think he preferred to losing 
20% of the strength rather than 33% if a bolt failed.

I went with the three 5/16" solution, though, as it was easier
for me to enlarge three holes than to drill two new ones.  
Bruce was better equipped for drilling stainless than I am.
