But this time around I'll do it the careful way by using the lathe. Zinc, much like brass, can be fussy stuff to work on.

I used to inject-mould zinc... at 830*, it doesn't even burn when it touches you. It sears. Instantly.
It's very hard though. Even foils of Zinc can withstand pressures that exceed what you think it should be able to hold. That's probably why they use it on cables and flexible drive assemblies.
