Re: TVT - Start of Steam Operation

I remember reading in an old book- what book it was is lost to my memory now, although I think it was part of an American "Time/Life" science series my stepdad had- that the thermal efficiency of the finest steam engines was something like 8%.. and diesels about 20%. Dunno why those numbers have stu...

Re: 2019 16mm Show

That "coasting" feature really adds to realism! It makes the loco seem much smoother, as hough it's gliding along the way a real steamer does rather than grinding down the tracks the way a lot of electric powered models seem to.

Re: Another Wild Rose Project

How I wish I lived nearby and could nip round for a visit to see this model being built. I've always wanted to build my own steam engine, but the lathe and mill work seems so daunting. I'm enjoying this thread. Sometimes when I see how easy this stuff is for guys like Tony Bird for instance, well it...

Re: 2019 16mm Show

Where are those videos..!! I have only seen one that was sent to me by email from our area organiser and that is of the modular layout he has at our local shows. Try this one - https://youtu.be/qqapRNexydI - Laurie isn't a garden railway modeller so it's interesting to see what caught his eye. Apol...

Re: Run time

Since Roundhouse engines don't have a steam dome, the only place for steam to accumulate is along the top of the boiler where you've left some space. Without exception, I believe, all Roundhouse locos have a turret on to which the regulator is mounted. The turret performs the same task as a dome, i...

Re: Mamod Stirling

Well, I like it. Lots of opportunity for adding loads of details, and looks like decent-sized cylinders. It still somehow has the look of a "Mamod" engine about it, too.

Re: Another Wild Rose Project

It won't be a failure. One of my favourite adages is "Once begun, Half done".

It doesn't need to be perfect. No steam engine ever was -possibly with the exception of the Montreal Locomotive Works' Royal Hudson class- but I am sure you will make a running engine in the end.

Re: Run time

Since Roundhouse engines don't have a steam dome, the only place for steam to accumulate is along the top of the boiler where you've left some space. So does that make my Mamod SL3 more sophisticated than the Bertie in that respect? Yes, it does, if by "sophisticated" you mean "like the big engines...

Re: Another Wild Rose Project

I'm looking forward to seeing this. I have always wanted to get into making metal parts and building an engine. It will be great to see how you progress at this. The wheels look like a promising start. I would be pleased with myself if I made those.

Re: Multiple small projects

Thanks Rod. Building models is a pretty solitary pastime where I live. It's nice to have the ability to share it with others even if it"s just in the internet. I've finished the brake rigging on the guards van. It's hard to see because it's all black, but there's a Brandbright vacuum cylinder under ...

Re: Run time

The best part of a run is the middle bit. What happens is the gas tank slowly heats up, and as it does, provides a higher gas pressure to the burner. If you want to maintain a steady steam pressure you need to continuously turn down the gas for the first part of the run. Meanwhile, you've started wi...

Re: A new MSS locomotive and tank wagon

I notice that dream steam offers an "intermediate ugrade kit" seperately that includes a pressure gauge, displacement lubricator, steam regulator, and other goodies for about £70. The green loco in the picture has a pressure gauge evident through the spectacle so I would hazard a guess that it's bei...

Re: Multiple small projects

I'll bet it would look quite good on those steel wheels though- I'll snoop around the hunting section of the hardware shop this week-end and see if they have any.

Re: Multiple small projects

Thanks Graeme, good advice there. I suppose I ought to have known gun blue solution would be black- you don't see many blue guns. If you look closely at the van, there is actually a great big white-metal vacuum cylinder under there. Like you say, it's quite heavy. I had to shorten it a little becaus...

Re: Multiple small projects

That's true, I never thought of that. I painted my loco wheels but not any rolling-stock. Can you recommend a way to chemically blacken them? That sounds more durable than paint. I'd like to do that to the cylinder ends on the loco, too.
