The Home Machinist!

That's not the only time LBSC did that particular trick...Britannia has the same problem !

I'd tend to guess at about 24.

Steve Alder had/has one here at VIME, and I know of the one at Kingston, Ont. You are listing 3 more, I know MEG built at least 2 for delivery- the one the photo is taken of upthread on the old VIME roadside loop with the odd tanks...

Charlie Docksteader's program on the Bitter Creek & Western will let you see what happens in a graphic way. The "best" way to work your way around how the different adjustments is to make a mockup set, probably 4x larger than the model will be.

There don't need to be any stays in a round surface, typically...the thickness of the round surface has to be able to take the hoop stress, but there is no need for stays, which renders "Marine type" fireboxes far easier to make... That being said, I would recommend cutting apart this boiler to figu...

I believe Carrdo (Don Carr) on here owns the patterns and drawings for the Hoffman Hudson. It makes a very powerful engine, or at least ours was basically unstoppable. It also weighed rather more than dad could lift on his own when he was my age...

I think, from what I have sketched out here for Dad, that you want about 1/3rd the L of the height between the top of the tubes and the base of the smokebox. That's also based on wanting the impingement (1:7) triangle to take effect above the bell mouth in the chimney. I have the images that I drew ...

Tony and Dougal Hubner designed MEG, and I know of at least 2 up here (Steve's @ VIME, and one at Kingston Ont), plus Harlock on here has one. That's 3 finished locos, which isn't too bad. I don't believe they "went under", but I don't think they are active, which is rather a different position. The...

Equally important is going to be the gloss/varnish effect. Colours which look too dark if they are matt/semi gloss may well look quite a bit brighter if varnished...

Well to the north, up here in Canada, I believe you will find Abbotsford MES with about 1200' of 2 1/2", 3 1/2" and 5". BCSME has a back and forth 3 1/2" (not finished, last I heard...) and a mile of 7.5 or so. Vancouver Island Model Engineers has a 1200' 3 1/2, 4 3/4 & 5" raised track & about a mil...

Ok- so from a full sized prospective, with oil fired boilers, the way we treated the fireside was to leave the last 12 hours of soot ON the boilers if they were going to be dry. If you know that the fireside is going to get wet, then you want as little as possible there. It's also the reasoning behi...

Another option is to use low silver content (high melting point) lead solder. Be aware, once you do that particular trick the boiler is nackered for trying again with silver, as they won't stick to each other, or in the vicinity of lead fumes. A lot depends on "how bad" it really is- things you don'...

I too am surprised about her passing,
