I'm hoping to build a small pipe organ this summer, and as well as a
rank of wooden pipes, I would like to make a set of small metal ones.
The largest would be 2', going down to a few inches. The trouble is
that most organ builders cast their own mixture of lead and tin for
pipe building, which I don't belive is comercially available. Can
anyone suggest another sheet metal that is:
Easily worked
Solders well with an iron
Isn't too hard to get hold of
Isn't going to break the bank
Sorry if this is the wrong group; many thanks.

Have you seen this http://www.youtube.com/watch?v=0rb8FMvbe20 . Looks
like it might be fairly easy to replicate. Christopher, in another
reply, mentioned higher levels of tin in better quality work so maybe
pewter (britania metal) might be an option, although I have never
tried to solder it with an iron only torch. It would also help if you
mentioned your location.

That's an interesting video. To elaborate, this is what the book says
about alloy composition:
"In the last hundred years or more, lead-tin alloy pipes for organs have
been made with as high a composition as 85 wt% lead and 15 wt% tin.
However, the organ trade had the view that no alloy for organ pipes
contain less than 25 % tin, and in really good work no alloy with less
than 55 % tin should be employed."
Best wishes,
Chris

I wonder what the pewter I have would work like, it's 92-6-2, 92% tin,
6% antimony, 2% copper.
And the things you find on the internet

I thinbk Pewter is too brittle to be rolled into tubes.
