The bastiches scrapped out all of the spares from the 12 cylinder diesel
engine at work without telling me a few months back. Included were a couple of
pistons. The engine is 17 1/4" bore by 21" stroke, so you can imagine the
usefulness of the pistons :-(

I have the feeling that some silicon rich master alloy might help when I try
this out.
