Re: Propane Quick Disconnectss

I'm using Swage QC4 for propane on the little wagon. They seem to work OK for it, but be aware you are almost certainly outside of the technical advice of the maker by using them for a flammable gas. (I don't have access to the Swage books any more, so can't comment if I am or not- some of the swage...

Re: Ed Perry

Strange that, the GWR did it, as did other UK railways...before they were nationalized. I seem to think the Standards have steel boxes, not copper... (but it's not so important when you scrap a copper box to build a new one- the $ from the old one goes into the new one...not like with steel, where m...

Re: Easy 1/4" check valves?

Dad uses a set of metric end mills for making flats. Conveniently, they are generally just slightly larger than the common ball diameters, but not so much as to result in giant sideways float. (IE 5mm=.127", 8mm= .203.)

Re: Threading to a shoulder?

What about dropping a parting tool in between the thread and the shoulder after threading? (or before, for that matter)

Re: Oil firing in 1" scale

#60 holes sound big to me, but we had more pressure. 56/57/60Y5/2500, IIRC. meaning, #56 outlet hole, #57 inlet hole/#60 steam Jet, 5 sets of orifices/2500 lb hour fuel flow... so at a #57 hole for fuel, and 50-250 psi fuel pressure, you get up to 500 lb/hr of fuel flow. At 50, it was around 100 lb/...

Re: Using a steam indicator

At this point we need to ask a very important question. One which I think I have missed completely looking over what I have posted on the subject. That Question? Did we answer the original question brought forth by the young lad? It would appear that you guys have answered the first two questions, ...

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...
