[Farmall] Ttian fuel tank repair

[John Hall]

I took a couple pictures when I was done. One of the "die" bolted to the 
faceplate and the other of the part. Then the batteries in the camera went 
dead. If you want to see some real metal spinning there is lots to see on 
Youtube.

Sounds like your grandad knew what he was doing! While researching metal 
spinning I saw a couple of multi-piece mandrels. I think it would be a fun 
thing to learn how to do.
