i probably am at a lesser skill level than you but i think the project is worth at least trying. the idea for using the Bachmann junior's chassis is a nice one and i will look into that. i had been thinking maybe getting a terrier chasssis and switching out the wheels but i haven't settled on a proper chassis yet. the only thing i know i will use is the saddle tank from a smokey joe to make the saddle tank, the rest is still up in the air right now.
