Arnold I must sing like the rest and that's an absolute beauty and what a runner that slow speed is awesome. That engine is differently on my list to build and the color. I like........................ :praise2:

Once again, many thanks for the kind words All  :praise2:

Whiskey, I think I'll skip the hide; there's enough on the two Okavango drums beside the trolley the engine is on, and that's enough for me  ;)   

Achim, yes; it will get the governor and trips one day; I first wanted to finish it to "basic" level.  I'll get back to the governor after about two other engine and some tooling builds  :ThumbsUp:

Carl, you must know by now I'm no darn good at dancing  :-[ .  No need to be sorry about not being around much; I know exactly what you're talking about; haven't been a shining example myself of late...

Bob, I'm really really glad you feel a part of the process - like you say, I may have built it, but it's the team's engine  :ThumbsUp:

Phil, no need to feel guilty about commenting on running directions and so on; I've never in my life seen a real mill type engine in operation, so have no clue about that.  That's another tidbit of information added to my "books" - and when I build the governor and trips, I'll turn the eccentric through 180o to make it run more true to life  :)   

Kind regards, Arnold

Arnold

The reason a "typical" mill engine goes the other way is so that the load on the crosshead slide always bears "downwards" onto the bed of the engine on each power stroke.

Not a big deal, but just thought you might be interested to know why.

Thanks Phil - I thought things through and that makes perfect sense  :NotWorthy:    I'm curious now - were there engines built with just a bottom slide for the crosshead, i.e. no slide/containment at the top?  I'm thinking sort of like a Myford lathe's ways as the crosshead guide and the apron being the crosshead.  Under full engine power the crosshead, combined with its weight, would bear down from the top, and in rare circumstances where there would be no load on the flywheel, and the engine steam supply got cut, possibly creating a vacuum in the cylinder, the under-side of the slides and a wrap-around on the crosshead would keep it from lifting off... 

Thank you very much Ronald  :NotWorthy:

Kind regards, Arnold

Plenty like that, usually had a rebated bar to stop the cross head lifting.

I'm a bit late Arnold, but congratulations, that is a superb bit of work. I'm a Laphroaig man myself, and I'll have one for you. Best wishes, Hugh.

Thank you for the compliments kvom and Hugh  :)

Thanks for the information Jason, Jo & Phil.  Hmmm...  The engine Jason linked to looks like a nice candidate to build a smaller barstock model of - say 1/3d or 1/4 scale...  :thinking: - Or a modified version of Elmer's #41 Factory Engine or #33 Mill Engine...  Rats...  Now that lot is in conflict with an attempt at a simple Ruth's Rotary, a mad-cap six-cylinder-many-gear-radial-just-for-fun compressed air engine, and a simplified live-steam version of a vertical portable steam engine from a "local" (900 km round-trip) museum...

Kind regards, Arnold

Brilliant Arnold, fitting first version of MEM's own engine. Quite a feat by all involved I think, well done.
