Re: Kirkwall Central

Dad will probably visit- with MY loco !

Who knows when I will next be in Southern Ontario, though I'd love to come visit.

I'm assuming 4 3/4" rather than 5" ?

(his loco's are 5", or 3 1/2")

Re: Royal Scot Tender

You would be looking for

ISBN-10 1874103496

LMS Locomotive Profiles #1, The rebuilt Royal Scot's.

I thought I had more of the loco profile books, but apparently only have the ones on the Black 5's.

Re: Making a boiler without a lathe

The boiler should not be made from brass, use copper or bronze. The zinc in brass dissolves into the water over time and it becomes porous and weakens. Brass works for piping, tubing and external fittings, that can be easily replaced if they age out. The answer is "it depends". We've tossed a whole...

Re: Making a boiler without a lathe

Does your collage/university have a shop you can get time in ? I know U of T Chem Eng used to have a very friendly machinist ! Making a boiler using pre-made copper parts is perfectly fair. HOWEVER, I would highly recommend silver soldering or brazing the boiler together. If you are going to fire wi...

Re: Recommendations for a hand pump?

It depends on the size of the engine. A hand pump is practically useless on a 7.x" gauge, 2 1/2" scale Northern... but a very handy thing to have on Tich in 3.5" gauge... In general, the requirement is _at least_ 2 ways to get water into the boiler, one of which must operate while the engine is stat...

Re: Alcalde & Coalfield High Line

Jack, What about following the example of the Bowen Island railway, and using 40% to remove rocks? Nothing a little HE can't cure ? Or if you are close in to houses, there are some water activated cracking agents, which you put into holes drilled via a SMS (Hammer) drill in the rock. It's not defeat...

Re: Green Velvet Cylinder Squeak

Probably thickness of the oil. Is the shay superheated? My Caribou doesn't like TK460, but is happy with what I assume is 1200w (it's Gulf, so was 20 years old 20 years ago...). Superheated, and tight piston valves. With the 460, it tends to seize up at speed. It too suffers from small wheels and fa...

Re: Coal purchase

The answer is, as always, "it depends". As in, it depends on which coal you get. We've got a limited amount of what is reputed to be Pocahontas #2, which burns quite nicely. By far the best burning coal I had was some pressed coal from Nanaimo. ("and dam'n all patent fuels !"). However, as Nanaimo c...

Re: L.E. American & Feedwater?

I tend to break out the math when solving this sort of problem... Figure out the volume of the cylinders, and the volume of the feed pumps. Use some conservative numbers for N of the feed pump, like 50%. See if the feed pump will feed more water than the cylinders at 100% live steam fill/stroke. If ...

Re: Understanding types of copper?

I know my dad has just run into this in a 30 year old project- it has a range of (I assume 7/16, 1/2 and 9/16") tubes for the flues, and is a tad bit hot in the smokebox as a result. That's because the previous to that boiler he built was with 3/8" tube, and it steamed like a constipated elephant. A...

Re: Shortest steam up in history

Marie & Charlie Meyer's had HOSS (4077), which was one of the ex Hosmer (BC) Porter Air engines, I think they used a compressor towed behind rather than a HP system. That is a 3' gauge railway- it was for sale in the Dells, Micheal their son posted about it on here. I'd suspect you would need about ...
