Has anyone used these for VSF gaming? If so, what were your thoughts, alterations, treatment of steam tech etc 
cheers

I used to use the rules for colonial and later VSF gaming. I used an adapted version of 40k written by Jervis Johnson (I think) for colonial games, then added various bits to it.
I seem to recall the tank rules work rather well for steam tanks as they are...
Anyway, attached are the modifications I used. There appear to be a couple of army lists there too, I assume I added these for a game. I don't have WHGW to hand, and these are rather old, so I can't really comment on them. As noted above, quite a lot of credit goes to the colonial adaptation of 40k (which I used to have somewhere, maybe you could find it online?).
