Material choice

[Dalee]

Hi,

I'm building a Paddleduck. I want to make the cross heads and they are supposed to be made from brass/bronze. I don't have a chunk suitable to use.

Friction and sticktion has me wondering if I can substitute either steel or maybe cast iron. Or am I just over thinking?

Thanks!

Hi Dale,

its not possible to answer if You don't tell which material it is on which the crosshead slides.

Anyway, dont use mild steel n mild steel, that makes for poor wearing properties.

I used drill rod for the crosshead guides. You could sleeve a steel crosshead with brass (or PTFE) fairly easily.
