Title: MEM Corliss in .40 scale
Post by: gbritnell on July 28, 2018, 07:43:53 PM: Although I have some more small parts to make, valves and railings, the engine is complete and running.
Thanks to all who followed the build.

Post by: Johnmcc69 on July 28, 2018, 10:26:18 PM: Just beautiful George! That is some beautiful machining & shows the level of talent you have. When you cranked up the air while running it, not even the slightest run-out on the flywheel...

Fantastic work George,
John

Post by: gbritnell on August 10, 2018, 04:35:28 PM: Gentlemen,
As far as I'm concerned the Corliss is finished. There were a couple of other things I wanted to do with it, railings etc, but taking apart all those tiny nuts and bolts every time something needs to be done is painstaking. Maybe over the winter I'll have a change of heart.
I cleaned up the aluminum platform for the video and pictures. It's not buffed but polished with aluminum polish. I took cotton swabs to all the parts to get the excess oil off. The governor works well. I cut a strip of leather from an old wallet, .040 thick x .080 wide for the belt. I tapered the ends and glued them with CA. The first few times I ran it the belt stayed flat then it decided to run on edge. I'm not going to fool with it unless it quits working.

What a lovely little engine, and built in such a short time as well.

I hope you wont be offended by me mentioning that most full size mill engines would be running the opposite way.
Due to the fact that yours has a trunk guide it does not make any difference, but a lot of engines had slide bar cross-heads and the forces need to be downwards through the engine bed, hence they ran the other way. I may be proved wrong but I don't think I have ever seen one running "top of flywheel towards cylinder"

I am awe of what you have achieved here despite my comments above. I only wish I could be as productive.

All the best
Phil

Post by: Ramon Wilson on August 11, 2018, 08:10:52 PM: George, that really is a remarkable piece of miniaturisation :praise2: :praise2: Congratulations on such a stunning result :ThumbsUp:

Whilst I concur with Phils observation on a technical point it takes absolutely nothing away from the finished model - it's as I thought it would be - truly, a real 'Gem'.

Post by: gbritnell on August 11, 2018, 08:35:48 PM: Hi Phil,
No offense taken. To be honest I didn't give it any thought. The crank happened to be at BDC so I advanced the eccentric to open the intake valve in that direction. You are correct with your observation.
Thanks for the kind comments.

Wow ! Even Keith Stewart (Nevil Shute: "Trustee from the Tool Room") would be amazed.

I have started to read Trustee from the toolroom and notice he also wrote book called Sliderule so is this on the same engineering theme ? if so i will try and get a copy
