It is called a green sand mold and i have never had trouble with air bubles and impurities are nearly impossible after all i use high quality bike aluminium. If it is good on bikes it will be good on a gun, i can make the wall .5cm thick or 10cm thick i can make nearly any part, so casting at home is really great.

Aluminum's strength is highly dependent upon heat treatment processes. As such, the very same metal that gives you a high strength bike could give you a pathetically weak gun.john bunsenburner wrote:It is called a green sand mold and i have never had trouble with air bubles and impurities are nearly impossible after all i use high quality bike aluminium.

In other words, it's not enough to be able to cast aluminum. You must also be able to heat treat it.
Do you have that knowledge?

I have the basic knolage yes but it depends on the specific alloy i use. I cannot really say i have the knolage for every alloy, mostly because i dont, but i am a fast learner and after maybe and hour or two and some practice i will be able to heat treat what ever alloy i end up choosing.
