Large engine ID
« on: April 28, 2020, 07:22:47 am »
Hi All.

Don`t post here as much as I should.

Somebody suggested this large engine could be from the USA. Any ideas as to what it is? It`s shown next to a stuart 504 for scale.

Looks like it might have a Muncaster flywheel, so I`ll have to dig my book out and see if its one of theirs.

I actually bought it for the boiler, but I do seem to have a knack for buying unidentified engines. Big though, it`ll be interesting to see what the bore and stroke are. Might even be bigger than my Stuart #9  ;D

  Well, it does look cool. 

  I too have picked up several unidentified
engines.  Must be because they were not
very expensive.  I have a thread on this
site asking for ID with my engine.  Too nice,
I think, to be a complete home design/cast/build.

  As to the bore/stroke dimensions.  The stroke
ought to be easy to measure.  Then, you could
make a reasonable guess at the bore by measuring
the cylinder diameter and guessing the bore down
from there.  I'd really like to know.

Good Luck,
Wayne

I have no idea on the maker. 

I expect that it came from a casting kit. 

It looks well made and is a nice size with the Stuart Boiler.

Have you steamed it yet?

Well it's arrived 😁
Unfortunately the boiler has an old ding but other than that it looks usable.

A bit more info on the engine to help with the ID...
1 1/4" bore and stroke
5 1/4" curved spoke flywheel.
Has casting number 50 under the base.

Oh and it's very heavy😁

More photos to follow but any ideas?

  Hefty bore and stroke.  Might be a steam eater.
Could be a powerful engine at the right pressure.
Try it on air first and put up a video.

Good Luck,
Wayne

Came across a photo of the Bruce engineering R&B has engine. There are similarities in the castings but the bore and stroke are double the size.
