Help Support Home Model Engine Machinist Forum:
That was the very first engine I ever started building. Messed up the first piece. Decided I didn't have the skill to build it so I moved on to something easier and never made it back. Dale Detrich completed one and it ran very well.
Good luck and I'll be watching.

Could you point me to which issues this is in? Please and thanks!
Frank, It is in the June, July, August and September issues Year 1946
You can see them at Popular Science
Cheers

Thanks much - There is so much cool stuff and not near enough time to look through in those old magazines, brings back many memories and it is very interesting to see so many parallels to today like titles of those old articles that could be written today. And also how many things that are actually happening now were sort of predicted somewhere in those old articles.
Hi All,
Got some more of the cylinder done today.
Used an arbour to hold the cylinder, uses a 1/4" bolt with a 1/4x32 thread for the plug hole. I went with a 1/4" plug as the 3/8" plugs are getting harder to get, the 1/4" ones are readily available.
Machined the ports for exhaust and inlet. Set up in dividing head for the correct spacing.
Also machined the cooling fins, I like the look of the fins on the O&R engines, so I reconfigured the fins to suite.
The top of the head were machined with a 0.8mm slitting saw, and the cylinder fins with a 0.9mm HSS tool. Had to grind this one up.
Hope to get more done tomorrow.
Cheers
Andrew

http://www.modelenginenews.org/tinysuper/index.htmla usefull reference with history
nice example on youtube. Is this yours ghostly?
nice build going on here
cheers jeff
Yes its mine
Hi All,
Done more, I do not have any black iron for the transfer port, had a 3/4" copper fitting, good enough, formed up and silver soldered to cylinder, then cleaned up.
Remounted the cylinder in the lathe and machined a couple of thou under sized.
Mounted in mill and machined cylinder flange, drilled mount holes, and machined out transfer port.
Then lapped and honed cylinder to size.
Mounted piston blank in lathe and machined to size, and cut ring grove.
Marked out positions for milling. Mounted in mill, drilled and reamed piston pin hole, machined transfer port, machined transfer and exhaust deflector's, machined piston internals.
Cheers

Nice job so far. I might revisit my plan to build this one some day.
Nice work so far. This brings back memories of when I first started building.

I know that engine! I had a neighbour who built one, and it used to sit on top of his fireplace. I don't think he ever had his own machinery, so his was probably built during his time with Handley-Page. He reckoned as an engine, it was the "screamer" of its day. His cylinder, piston and head were long gone when I first saw it, though the very mangled remains of the conrod were still there! He also told me that the crankcase material came from an aircraft propeller... That would sound typical of the U.K's austerity period of the 1940s and 50s, when fresh metal was hard to find for modelling. Don't forget that food rationing only stopped here in summer 1954!
He explained the cause of the failure was his choice of the type of bronze he selected- looked like continuous-cast phossy bronze to me, but this was 35 years ago, when I was a schoolkid...
Years later, I'm sure that I found the design reproduced on the Model Engine News website.
Dear old Morris, as well as his engines are long gone now.

Sorry about the double post! Just checked, google...
model engine news "tiny super"
and it'll come up straight away.
