Hi All, I'm going to assume (gosh, I dislike that word) that Ern Grover
is referring to the article by Craig Brougher, 'Hot Hide Glue --
Questions & Answers', since there have been no articles titled 'Glue and
Adhesives' over the past few days. Ern Grover states at the end:
> "Personally I like hide glue just fine -- for joints that may require
> disassembly in the future (like in violins or guitars)! Because the
> adhesive is thermoplastic it can be softened with a hot knife and
> the parts can be disassembled if needed. It is also more likely to
> be historically correct if that is a serious consideration -- face
> it, back in the 1800's there wasn't any PVA!"
I'm really glad he said that, because the aim of Craig's article was to
explain to people that hot hide glue can be, and is, used in virtually
every aspect of 'player piano rebuilding'. I'll repeat that: player
piano rebuilding, not clocks, cabinets, houses or anything else
(although hot hide can be used for thousands of other jobs). More
specifically, we're talking about parts that WILL have to be taken back
apart at some time in the future.
As a player piano rebuilder, one of my main concerns has always been
for the 'next guy'. All player rebuilders have encountered rebuild jobs
where white glues were used. They are always a royal pain in the
behind. Sticking (no pun intended) with tried and true methods not
only helps to maintain originality, but it makes the job as easy for
the next guy as it was for the first guy.
Let's try to agree on what we're talking about first before throwing in
a whole bunch of other distracters. Just because a cook uses cooking
oil for food doesn't mean it can be used in your car. Focusing on the
topic at hand always help avoid confusion.
