sand forming

[mk]

I just put it in here again, because it is really hidden in the valveless forum.


U-bend production steps:

1. crush a/the pipe (not completely ready) -> kazoo only!
2. put some sand into the pipe (maybe some welding at the ends, but at least "closed crushing" would be needed, I think)
3. heat the (piece of) pipe in a campfire, with a torch or s.th. else
4. bend the glowing pipe around a model radius
5. cut the end caps and put the sand out of the pipe

It came to my mind, because my gradfather told me that some people bend their own motorcycle exhausts during GDR time, because getting spare parts was a headache those days.

I haven't tried this methode yet.

What do you think about this methode?

If you weld the ends up make sure you leave a hole for steam to escape, the sand is never that dry and a little steam will always result from the heat.

Yes the method works but take in to account the above.
