With epoxy repairs like this a _thick_ mix (slow acting hardener is
preferred, find at ships chandlers); and rather than making dams, mould the
epoxy under plastic wrap. The wrap does not stick to the cured epoxy and -
importantly - keeps the epoxy surface smooth.

Personally I prefer to insert a bit of wood for such repairs. 

Interesting how much the saw looks like a Sheffield one from this period.
Can one really talk about a US saw industry before the 1870 or so Disston
innovations? Or are the US makers really a "branch" of Sheffield, just like
Birmingham?
