Cretors #1 Horizontal Steam Engine Build

(1/21) > >>

rstreift:
It's been awhile, but well along the way toward completing an engine.  As I knew there would be many interruptions, I kept a log offline.  Now that the end is in sight, I'm posting it and expect that I'll catch up with the build by the time I get the completed parts posted.  Please offer comments/suggestions as there is usually more than one way to make a part and I could use all the improvement I can get.
The previous build log was the Cretors #6 Oscillating Steam Engine.  Since I also have a Cretors #1 Horizontal Steam Engine kit I figured I might as well build it in sequence.
This is modeled after an engine that was prolly built between 1885-1918, as best as I can ascertain, for use in peanut and popcorn street wagons, built and sold by the Cretor’s Engine Company of Chicago, IL.  I found information that there were several different engines designs numbered from #1 to #6. The last catalog I found was a 1918 version and it listed the wagons as electric with optional steam power.  Catologs were found at:

The Kit
As with the #6 engine, this kit was purchased by my late father in 1999 and as far as I can tell, the current offering from Myers is the same kit.  Obviously, one has to open the box 😊, after doing an inventory of the castings all were accounted for as well as the prints. The prints have Paul R. Breisch of Royersford, PA as the original work for this model drawn in 1969. 
There were four architecture C size prints, labeled S330 to S333.  S330-S332 are of the engine and S333 is the Governor.

The Governor

The Drive Column, #S333-D
I’ve never built a governor; this will be a first for me.  The drive column seemed like a good place to start as I can use the external thread as a gage for its mating part, the “gove yoke”.  Using a piece of SS, I clocked it in the lathe to chase the 9/16-24 thread.  The cutter is mounted upside down and the lathe is reversed, by doing this I can thread moving away from the shoulder.  A minor diameter flat is cut about 3/64 wide for the cutter to start from.

The next part is the taper.  I use a sine platform with a 5” sine bar with a 0.234 stack to setup the taper on the compound slide, but first I need to zero the bar on the platform.  Once zero’ed, on goes the sine bar and stack, then the compound is adjusted until the indicator doesn’t move as it is compound screw is turned.  Looking closely, one can see the compound and sine bar are parallel.

The taper is turned and a 1/8” radius form tool completes this feature.

The 3/8” hole down the center is spotted, drilled, and reamed.

Once it is parted off, it is mounted on an arbor to turn the fit for the gear.

The Spindle, #S333-S
I was eyeing the body casting to do next, its features need the body squared off and one side needed to be -0.000/0.005 tolerance to the bore going the length of the part.  I kept thinking I needed a dummy shaft in the bore that extended past the threaded part of the bore.  It finally dawned on me that the spindle is exactly what I needed.  It threaded into the body and the drive column has the gear to which the tolerance comes from.  So, the light came on and I pulled out the spindle print.
Into a ½” collet goes a bit of brass to get faced/spotted/and drilled through for the valve stem.  Then tapped for the gland nut.  The diameter is turn down to 3/8” for 1.875”..

I swap out the collet to a 3/8” and hold the part to chase the 3/8-24 threads.  I considered using a die, but chasing it would eliminate any slight error a die may introduce.

I really like these engines and have been eyeing one up on the Myers website. Following along and hope to see more pictures  :popcorn: :ThumbsUp:
