Best I post a short vid of my first actual working metal project, Oscillator of course. Rattler is a better name. Not knowing any better i made the crank one piece and the cylinder assembly is also one piece. Really surprised that it ran

Very nice indeed Robert.
I do like the way you have built the regulator into the design.

Hey Foozer - nice little engine and especially like the regulator!! I may use that idea when I make my next wobbler. Is the entire engine your own design?

Flaws and all. Regulator just came about as i didn't want a hose sticking out the top so fiddling around with how to connect one without be too unsightly it just sorta fit the bill. Brass is good for hiding booboo's I should take a shot of how the flywheel is attached underneath the layer of brass :)

Nothing wrong with that Robert... Runs better than my first steam engine attempt :thumbup:
As said, nice reg' on the frame, all these little things get stored for one day incorperation into something I might build! :ddb:
So in true tradition............. What's next? :thumbup:

By the size comparison with your hand it looks to be a pretty good size engine.
They all seem to knock a bit.
Nice job by the way.

Hey Robert!
That's a pretty snazzy engine. How about some more pictures of it so I can drool?

Ah shucks, pic of the shelf Queen, boy they get dusty fast. Camera shows all that I dont see. Brass collar on flywheel is hiding a spring. back side of flywheel has a notch cut into it that engages a pin thru the crankshaft. Spring keeps flywheel against pin. All cause I broke the tap off in the hole that was supposed to attach the dern thing.
Other brass cap of course covers the cylinder tension spring. had to keep the theme going :)

Ya, the cameras eye picks things up like that and shows you those things.
Neat fix for the broken tap. Very ingenious. Learned a new fix. :thumbup:

I do love a good "work around"
More details on the regulator please. (for newbie me) :scratch:

Nothing fancy. Just like an air flow gizmo for the fish tank. Piece of brass close fit into the frame down far enough so the port hole will intersect. Side of brass was drilled in just enough to get the feed tube to fit for solder. Drilled into this just past the halfway point and I think it was the tap drill for an 8/32. Drilled down from the top all the way through with the same tap drill. Threaded down that hole so when the screw goes down it covers up the inlet hole and well not really regulate the flow but rather restricts it. Works
I just didn't like the look of a hose sticking out from the top and that's all I could think of to avoid that. Rest was made from 3/4 plate and bits of brass, bronze, couple screws and such.

Suddenly I feel like chasing the stick HMM?? :)

A lot of thought has gone in there, some nice features.... :clap:

Very nice, well done! :thumbup: :clap:

Is that your own design or a modified one?

Have one of those Steam and Sterling books. Looked through it for something to make. The 3 cylinder wobbler looked good, "hey I can do that with what I have" wrong!
Maybe a 2 cylinder, wrong again. Good thing this one worked, I was running out of cylinders. The bride would say that happened a long time ago.
Drew it out trying to keep it within the old "Golden Rectangle" bit for eye appeal. I just find it curious why some things just look better than others. Probably should measure out the final result to see how far off the end results were. Have noticed a lot of the Elmer engines seem to fit within these boundaries, got to be some reason they are so well liked.
Was a good learning experance. Can appreciated the talents of others. Cranks a one piece, lots of thump thump thump turning that down from a hunk of round. Cylinder, pivot pin also a one piece, a 2x2x4, thump, thump, thump. I sure see why a lot of soldered build ups are done, but I always make the easy harder than it needs to be.

I didn't get to mine this weekend... you wanna come over and give it a go? :lol:

Practice hitting the numbers a little, and you can make press fits. Especially for stuff like the crank pin (dowel pins are cheap), and no soldering necessary. If you miss a bit (too loose), there's always loctite. Too tight, and you hit it with a bit of emery paper.
Hey, If I can consistantly make a good press fit, just about anyone can.

Getting better at that. Got the little lathe "tight' enough to pull off that last little half a thou cut. Sequence of assembly is another. Exampled, flywheel web to be fit into the rim with the hub fit into the web. Did the web rim combo first (heat chill), wrong!
When the rim cooled it caused the little collapse seen in the shot. Live and learn. For a 4 inch dia flywheel.
