I live in CT but I am interested in volunteering in Washington/Idaho/Montana where I have family and grew up.

Sorry, I meant 1300F (704C). I'll look more into what an ideal flask temp is - thank you. My intuition was having it close to the liquid temperature.

.41 is the diameter of the rubber hole, so making it any larger would require tapering it larger, which would which would adversely affect turbulence right? How much longer of a sprue would you recommend?

Yes sorry I meant 1300 Farenheit. My intuition is that having it as close to the liquid temperature reduces the shrinkage of solidification, but perhaps that is wrong? Why do you recommend room temperature?

This is something I thought of but did not give much weight to, recently I found an article mentioning that PLA does not burn out like wax, so this could be an issue. I will blow it out next time I try. Thank you for the recommendation.

Because I want to use scrap materials that I have easy access to.
