NOW WE CAN DO SOME CASTING
So now we can start castings. I'm always excited about new molds.
I've been working on these patterns for months now so finally we can start pouring
and make dozens of them if we want.
Durango rounhouse. Mold sink. Don't do this in the kitchen sink. Not
if you want your wife to ever talk to you again. I've plumbed in an old sink and
have a trap underneath it to catch all the plaster chunks and yuk.
Here's the trap. About once a year it needs to be cleaned out. One of
those dirtiest jobs you see on TV.

I've just poured the Hydrocal in these molds and tapped them vigorously
to help remove any trapped air bubbles. In a moment they will begin to harden.
Before the Hydrocal gets too hard the backs are scraped smooth. It
must be done gently on the HS II as it is much softer than the 3110 rubber I'm used to.
Now we let them set up.
In 15-20 minutes the castings are hard enough to remove from the molds.
The castings are gently removed from the molds.
The molds are rinsed off and the process can start one again.
All that HO scale stuff looks so small! Where the heck am I going to
stack the new castings? Somethings got to give.
