I have this Buffet tenor from 1877 that I'm restoring: https://forum.saxontheweb.net/showthread.php?372286-Buffet-Crampon-from-1877!

I've just fixed the dent in the front.
Now I need to re-shape the bow guard. I've managed to get it alright but need to make a mold/mandrel to get a smoother and completely symmetrical shape.
I assume that sugru is too soft (I've never used it). Does anyone have any suggestion on how to make some sort of mandrel for hammering/ironing?
The part of the bow guard that wasnt dented is in perfect shape and I'd like to make a mold from that part and make a mandrel.

I might have to make another bow guard though, as this one has already cracked on a couple of edges from when it was dented. But I'd prefer to keep this saxophone 100% original due to it's historical value! So any ideas and hints are greatly appreciated!

Thanks for your thoughts

I've already removed the dent and I did of course remove the bow guard first. So that part is done.
The "crack" in the bow is only a deep scratch.
My questions is only regarding the bow guard.

Thanks. That's what I've done so far. It's just not smooth enough.
It appears to be made of aluminum or some other lightweight material...
It's not easy to work with anyhow.

Thats! Thats a great idea. Sounds perfect. Can't find it on their site now though. Is it a discontinued item?
Do you know another place to purchase from?
