Bel -- what do you use for your pressure chamber? Buying one new is pricey, somwhere around $300 USD. I've been toying with the idea that I could use a pressure cooker, but I wouldn't want the thing to explode when I run it up to 3 bars ( 42 PSI or so).
Another update:
The Alumilite white resin is curing properly. I've baked the castings for 5 minutes or so after the resin has cured, and now the white resin has all the properties that I like in the tan resin. In its favor, the white resin has a longer time before it starts to set.
I will post pictures tonight of the first few Pump Wagons made from the resin castings.
