Galooterati:

Jim Thompson asked, on impeccable functional grounds, what I have
against epoxy.

Part of my bias against epoxy is, I admit, professional prejudice. I
know that it can be reversed with heat, but for paper and leather it is
effectively irreversible. This means I don' likeit. I've used it (not, I
hasten to add, on paper or leather). No doubt I will again. But, even at
best, its a nasty feeling, nasty looking, hard-to-reverse synthetic.

Even for wood or metal I don't like it. This is a bit more objective. It
responds differently to expansion and contraction than wood or metal,
especially than wood. This means it will constrain the wood to expand
and contract unnaturally, and that means trouble. Probably means the
wood will break prematurely. Its not likely to be a problem on a chisel
socket, but I think a lot of the time people choose it as "stronger"
when the joined object will in fact be weaker due to differential
expansion.

In the case of chisels, my basic objection is really a matter of
elegance. There has to be a better, cleaner, more easily reversible way
than resorting to glopped on gunk. Its like any joint: you can fill it
up with wood putty, but thats not elegant. Cut it right to start with. I
figure that with a well-made chisel the handle ought to lock in place
firmly without gunking things up; and if its not a well-made chisel, why
am I messing with it? (Well, I do, all the time, but you get the
principle). Before jumping to the conclusion that the manufacturer
botched the taper of the socket, I first want to make sure that the
problem isn't my workmanship or knowledge. Socket chisels were prime
goods, well-made or else the maker folded. I've bought bad, soft
chisels, but they were always tang chisels, not socket chisels.

I figured: I must be doing something wrong. Bingo: I used the wrong
wood. I figured: there has to be a simpler, less messy, more reversable
fix. A more elegant fix. Well, there was. Epoxy? I sneer. Take that, running-
dog petrochemical capitalist multinational megalithic chemical companies
strangling the freedom and initiative of the small independant
craftsman!!!...

I do beg your pardon, really. Got carried away. Any moment there I might
have started on about "croft-boiled hide glue" and "proud yeomen..."

Under sedation in San Francisco. End of the week, nearly. Just as well.
