    School me on engine starters

    Hi popnrattle, the idea is to have a permanent, vaguely scale, starter on the engine.

    School me on engine starters

    It seems my web hosting service is having trouble at the moment. This is unusual. I have seen my pages down for short periods a couple of times now. When it is down, Firefox is asking what to do with a zero length page, and Safari confusingly asks if you want to download the page.

    Westbury 'Seagull'

    Thanks for the input, guys. I will be getting the parts made while I come to a decision.

    School me on engine starters

    I have been doing some experimentation on a starter for my Westbury Seagull, reported here: http://www.charleslamont.me.uk/Seagull/starter.html The basic engine is finished, but I want to make a proper fuel tank and cooling system before I try to start it. The rest of the build log is still way...

    Westbury 'Seagull'

    Fuel tank (brass): soft or silver solder?

    Metal annular ring growth at elevated temperature

    Petertha, your first assumption was correct. It is easy to overthink this.

    Oliver Evans The Columbian Steam Engine

    Very nice. What wood did you use?

    Difficulty with setup

    I regularly finish external threads with hand chasers. I have sawn off the handle tangs and use them in a toolholder. I find they have to be skewed very slightly to ensure cutting on the first tooth.

    Any call for 6" Atlas lathe 10100.....

    Rod, Bill, this is worth a look: http://www.lathes.co.uk/atlas6inch/page2.html

    Most efficient steam engine design?

    An engine with two-stage expansion is called a 'compound'. The physics is about minimising the temperature variation in each cylinder. In engineering practice it also reduces the effect of valve and piston leakage.

    Most efficient steam engine design?

    cbwho - I think there is a way to vary the valve events on an oscillating engine, using an eccentric driven disc valve equivalent to a slide valve. There is a drawing of one in the book 'Model Stationary and Marine Steam Engines' by KN Harris, but I have never taken the time to fathom out how it...

    Most efficient steam engine design?

    Considering the question Chuck says he meant to ask, the oscillator has no means of using the steam expansively, whereas the others can. If the Saito or the slide valve engine do have cut-off part stroke, this means that for the same bore and stoke, the oscillator could well produce a higher...

    Most efficient steam engine design?

    Max power for a given steam supply is a matter of efficiency, as has been said. Thermodynamic considerations are at least as important as mechanical layout. Personally in a smallish model I would optimise both by using a well insulated single-cylinder to minimise both surface area and friction...

    270 Offy

    I have thought about it a bit more and, surprisingly, it seems reasonable, if you see what I mean. It is worth remembering that Earth's gravity exerts on an apple a force of about one Newton. To lift an apple a metre in a second requires a Watt. So lifting a tablespoon of water three inches in a...

    a samll rortary table by g.h. thomas

    Oh I see, you are talking about fair use copying. I don't think your link helps much there; try this: https://www.bl.uk/business-and-ip-centre/articles/fair-use-copyright-explained There is no time limit on fair use, you can do that immediately after publication, but I think it is most unlikely...

    I like the new pump and am pleased you are now getting a satisfactory output. Out of curiosity I took your 54cu in/min flow and 3" head and calculated the power output (Q x P), but I am having difficulty believing my own figures. I make the flow rate 0.015 litre/sec and the pressure 0.00736 bar...

    a samll rortary table by g.h. thomas

    As I understand it, cover for literary content is the same 70 years after death, wherever it is published, and this has nothing whatever to do with the cover for the typographical arrangement. I think this is where your confusion lies. It would seem that there are two quite independent types of...

    a samll rortary table by g.h. thomas

    I am pretty sure it does not. Typographical arrangement is not related to the content. It does not even mean how the content is set out on a particular page, the fonts used, etc. It refers to the 'look and feel' or 'house style'of the whole publication, but not to the actual content. The look of...

    Where does it appear? I think you will most likely find this material is still copyright, but IANAL. dethrow55, the fact that you copied it from a site that had (very probably) broken the copyright does not excuse you from the orginal copyright. BTW, I have made one of these, and it is a very...
