Re: Exhaust tube bending
Depending on how you 'cap' the ends of your pipe, but if it is capped sufficiently to keep the sand from squeezing out, I'd suggest you don't heat wet sand.
Can you say, 'pipe bomb'? The steam that would be generated would make that a potentially dangerous thing to do. Even if it doesn't go 'boom' it might force the sand out under pressure. That could be nasty. Be careful, guys.
