This is an awesome build and very nicely documented so others can benefit.

Thanks,  Nick

I have gotten hold of some plans for the Stanley 20hp engine, prints came today, it would make a wonderful scaled down model.

Oo! Oo! Give me a pic or link! Gimme gimme.

Thanks guys!

Just spent the afternoon generating the 2d blueprints from the 3d model of the rest of the engine, lots and lots of parts to come! Had some issues with Fusion360 locking up, am in touch with their tech support (who have always been great to deal with, they squish bugs pretty quick).

Zee: Here is a link to what the Stanley engines look like:

The different pages on that site give lots of details and pictures, very interesting stuff.

As for the plans, I got them in advance of them going on general sale, they were measured from an engine in the Stanley museum in Maine. Sorry, but I don't have the rights to distribute them. I'll keep you posted when they go on sale. The plans are for the full sized engine, not a model of them, figure that someday I could scale the measurements down and do a model.

Thanks Chris. I'd done a little googling and you've confirmed that what I was looking is what I was looking at. 

I recall (I think young) woman coming on the forum that was interested in a Stanley. Maybe she'll come back when you start this.
You're going to do it right? Right?

It's a great project.

Its most likely definitely a possibility! I think!   


Its a couple items down the list, with some figuring out to do, but would make a great project.

Now to get eccentric (quiet back there Zee!)...

I was not able to determine the angle between the eccentric cams in each pair from the photos, or from the museum (theirs were already on the crank, did not need to be redone), so rather than make them as one piece for the pair, I decided to make each cam as a seperate part so they could be adjusted individually for best running. This actually made the construction simpler, since I could gang them up and cut all of them at once with one setup.
Started with a length of 5/8" stainless bar centered up in the 4-jaw chuck, and turned it down to the size of the outer cam. Made a shallow end hole for the live center (did not want it too large, and interfere with drilling the offset hole). Then came back with the parting tool, and cut the center grooves in each cam, as well as marking where the side hub and parting cuts would be made.

Then I got the dial indicator back out and moved one axis of the 4-jaw over by the throw distance from center of 0.053":

Then drilled the new starter for the offset hole

and drilled the starter for boring, going just deep enough to get past the first cam to leave the rest of the bar at full strength for the coming operations

followed (you guessed it) by boring the hole out to size

Next step was to take the side hub down, leaving it thick enough for a set screw

and finally parting it off. Since it was overhanging the chuck by a bit, I did the interrupted portion of the cut with the live center in place

and then finished with it removed

Then the drilling/boring/etc steps were repeated for each of the other cams.
Here are the four cams all cut, being test fit on the crankshaft. I did have to trim the length on one that was a bit long, keeping it all from fitting in the space between the bearings.

Last step on the cams will be to drill and tap for a set screw in the hubs....

No, you're good, I meant your evil twin zeepy!

Quick update - got the holes drilled/tapped in the eccentric cams:

and test fit on the crankshaft. Just need to cut the screws down a bit!

The cams are not set to proper angles, just put in place to test the fit. All good, so on to the Stephenson links...

Hi Chris,
 Oh yeah it's coming along......

On the Stanley front, thanks for the link to there's lots of info there. Would like to get more on the White that a friend has, the White site has lots but not back to his vintage.
My ME club had a Stanley mounted up it what is know as "The Sauna". Aka small shed with, at the time wood fired x dry cleaner boiler driving a Tangey, the Stanley, a steam pump & various small models. The boiler has been convert to liquid fuel, diesel, now...no colder in the Sauna but not as much hassle getting wood either. Any way back a good few years we built a, think it was 2/3 size steam truck & put the Stanley in it. Great fun to drive around, frequent stops to get up steam as the burner wasn't man enuff for the task! It was sold some years back so can't go check it out if required by you OR Zee, but I do know we're it lives!

Cheers Kerrin
