[Rhodes22-list] Chainplate access

[The Rhodes 22 Email List]

Graham,

How to remove a section of core is one reason I'm leaving it to the pros.
If I happen to see them doing it, I'll let you know.

Another factor that swayed me to the core removal option is that in the
area around the hatch opening, the liner had been glued to the core.  I say
"had been" because now, even though there is no core rot, the liner has
dropped away all along the edge of the hatch opening next to the
chainplate.  This gives a more access to saw and chisel out some core.
After the plate is back in place with the restored core, they will
re-attach the liner to the core as that adds strength and helps prevent
water penetration around the hatch frame.

The guys in the shop enjoy working on my boat because they say the R22 is a
study in how to design and build a boat that can absorb unusually severe
stress without losing all structural integrity.  Just like the right angle
bend idea for the chainplate allowed it to partially fail (perhaps the the
shock absorbing effect of the liner separating from the core was also part
of that) yet continue to function under normal conditions for another 15
years.

One thing these guys try to do is preserve the original structure and
materials in making repairs for me.  I've talked about that on this list
with respect to the mast step and hull-deck joint.  Now they are doing the
same with the chainplate repair.

Aside from the OSHA aromatics issues of using epoxy in a commercial shop,
epoxy holding onto the chainplate would make it more likely for the metal
to fail under extreme stress.  If that happened during the incident I think
caused the problem, my mast would have fallen.
