Point taken! I must also emphasize that in all of the brass parts
I've dealt with over the years, and it has to be in the thousands,
this is a first for me. In the late 60's and early 70's I was taking
apart Japanese brass models and trying to make something different
from them. From that time until today this has never happened.
This was a whole new experience for me . I now believe that these
parts were made from recycled material. I think it is possible that
there are other parts out there but finding them would be extremely
difficult. Should, and I EMPHASIZE should, these parts contain
Beryllium it will pose no special problem and I wouldn't be that
concerned. That is unless you want to start drilling into them all
day. Even then it is only the dust that is inhaled that causes a
problem. I have already replaced those castings with ones of my own.
Ones that I have cast and I know what the bronze alloy is. Remember
the whole project was to get the vent holes drilled into the doors!
One point I failed to mention in my original post is that; It was
not the entire part that was that hard, only a portion of it, and
that is really odd. As A brass investment caster myself I have learned
the hard way that using scrap just invites trouble. It is tempting
since the material that I use now costs about $25 a pound.
For those that have never actually messed with copper alloy
casting, as in actually doing a brass casting, it is somewhat like
dancing in Dante's inferno. You can easily get all the, blue, green,
white, and black smoke along with lots of bright flashes and flaming
heat to keep you on your toes.
