Re: Could this work?

It may work. It won't provide enough heat to do much, (it's about 4 hp of heat, if my mental math isn't too bad, which makes it about 1/6th hp output available), but it will provide enough to test & trial. I think we used the 2 kg/h burner with the engine, and I'm currently using a pair of SolarFlow...

Re: How Can I Determine Threads

BA pitches are totally rational. You are expecting that they are inch. They are metric...

Yes, an imperial diameter with metric pitches.

No, I don't understand why.

Re: Balanced slide valves?

In full size, you might want to see if you can find info on "Church's" patent slide valves, which were one type used on traction engines. I'm wildly going out on a limb, and going to suggest that a piston valve is a far better option... I know that Suction Hose (Ross) on Traction Talk has done quite...

Re: Coffin Feedwater Heater

Is it a CG type pump? I know that is what was on Red Devil (the SAR 26), so it might be one I don't have access from here, but might at work if it is, to pdf's of the manuals. It depends on what got digitalized...and if they purged the manuals post PRO scrapping. The books were in the 200 series in ...

Re: Tender pump and Steam Water Pump In Line?

I'd rather see a completely separate flow path for each way of getting water into the boiler. In particular, you should have at least 2 completely separate ways for most model boiler codes. This would not count as 2 different ways to me if I was inspecting a boiler. Again, it depends on the code as ...

Re: Restored Australian garrett in action

Has anyone built a miniature garrett? More than one. Station Road had a AD60 in 5", https://www.stationroadsteam.com/5-inch-gauge-ad60-4-8-4--4-8-4-garratt-stock-code-5924/ , Micheal Guy in Toronto is slowly working on a 2x 0-4-0 for 7.25" , my dad has another 0-4-0 in 5" part built (not his work) ...

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, ...
