Title: bronze casting
Post by: logoman on December 06, 2010, 10:49:23 pm: I would like to have some engine parts cast in bronze.
Can anyone recommend someone to do this?

I've used them for Bronze casting in the past (not engine parts) & they've always been very helpful.

In these days of minimium melt 10Kg >100Kg....then quality assurance >>:-( {:-{...being a chemical analysis of the melt O0....you may be better in using plain old BS1400 LG2 stock bar bronze material......Derek :-)

Google 'non-ferrous foundry' and see what comes up- I was looking a few weeks ago and there were quite a few results.

What an amazing process, real old fashioned cottage industry (we'll not mention H&S he whispers very quietly)
