RE: [hobbicast] I did it! my first casting
- That's a fair question. It leads to other high technology ingredients for
the successful founder. You need a clock and a means to measure weight.
So, how much metal are you melting how fast? When did you make additions to
the crucible and how much did they weigh? How much gas did you burn to melt
how much metal?
What was the weather like when you did these deeds? As in temp and
humidity. These are all variables that affect things like gas in the melt,
and the behavior of your molding materials. The more you know about the
environment of your foundry the better chance you have of doing the same
Keep track of your observations. Did that new sprue cutter work on this
mold? When you cut in the gates were they 1" by 1/2" or the do you care?
I vote for too much data. You can always use the scribbled on sheets to
help light the fire next time.
But, if you can develop the habit of taking notes, they will be quite a
treasure in a few years when you can look back and really be entertained by
your early efforts.

Fred, what kind of tings would you suggest taking notes on?
- OK, John, so you are telling me the loose piece of duct tape on my L-3 wing
really qualifies as an airspeed indicator?
