Track pins

[Jon Bradshaw]

I have another T16 but the pins were wornout so the guy I got it off of removed them all! I have some for a pattern but I need over three hundred pins for this vehicle. My other carriers have alot of worn pins as well.
Anybody have advice on how to make my own. I was thinking of buying steel rod and cutting it to length but other than welding a washer on the end how would I finish it?
Has anyone made them before?
Is there a jig I could see pictures of to make them?
I was told case hardened steel would work is that too hard or too soft?
Any help would be appreciated.
