Re: Recommendations for a hand pump?

dilly dilly - you can NEVER have too many ways to put water into a boiler...even if you never use them. I personally like pumps that go forward / back as opposed to left / right if you have that option. On smaller scales a left right pump can be tough to keep from derailing the tender. there is a se...

Re: Broken Drill Removal

FWIW: I use white vinegar with a 'pinch' of salt tossed in.

if all else fails and it is an important ($$$) part -> find someone with an EDM DRILL.

Re: Looking for info on this 3-1/2" gauge B&M 4-4-2 Atlantic

I have a running on air chassis for this loco in my basement with Walschaert valve gear, all done by he late Jim Stuart.

Jim used LE drivers and a few other bits and pieces but everything else is to his design from the original B&M plans.
