Which grade of. bronze

[Joe McKeanParticipant @joemckean81940]

I'm looking for a bit of advice on which grade of bronze to use for machining some cylinders out of.

I am following Kozo's instructions in building a Pennsylvania A3 Switcher and for the cylinders he recommends using leaded tin copper bronze but nothing more specific than that so could someone throw some light on the best grade to use.

Thanks in advance

Joe

The cylinder casting on my Murray's Hypocycloidal was made of something that behaved – as far as I could tell – very similarly to LG2.

SAE660 machines nicely and I've done a few cylinders with that.

I use sae 660 for all my bronze needs.

I have used LG2 for the cylinders of several steam engines I have made, machines nicely.
