I was going to make the connecting rod today, but I found that I no longer had the material that I wanted to use, so I moved on to the entablatures.  The Major Beam has a much nicer looking entablature, bit it seemed that that style would extend a bit far past the cylinder.  Jay Leno has a nice little beam engine and the entablature on his is attractive, so I went with one based on that style.  It may still get support columns, but for now it seems quite rigid and uncluttered. 

Tomorrow the shop gets a good flush.  The little engine still has a way to go.

The redesign of the entablature looks very nice indeed, makes a great improvement.  I imagine that there was a pretty considerable amount of careful machining involved to produce that component.   Dave

Yes, I like the alteration to the entablature a lot. It makes that part look "finished".
I was cut out to be rich ... but ... I was sewn up all wrong!

Thank you all for the positive comments. 

The entablature was made from a piece of .500” thick low carbon steel.  It was machined complete including the holes before machining the thickness down to size.  The tool path left an island in the center and a groove along the inner edges which I finished to .500 wide.  I inserted some .500 by .250 thick parallels into the grooves so that I could machine the part to .375” thick.  It sprung open a bit when complete, but I was able to straighten it.  The recesses were cut using a keyway cutter.

A little more progress.  I drew up my version of the connecting rod yesterday.  The material should be here later this week.  The eccentric and pulley went well.  Having a Hardinge HLV is great until you need to slow things down, (flywheel, pulley grooves…).  I ended up grooving the pulley with a ball end mill and rotary table.  At times like this. I miss my old South Bend Heavy Ten.

Lagging the cylinder is next.

Now I notice that you designed the upper cross bar completely differently. That looks really good! 👍
Is that your idea? Really well done.

thanks.  It’s loosely based it on Jay Leon’s full size beam engine.

My bar stock came in, so I moved on to the connecting rod.  It’s loosely styled after the Major Beam connecting rod.  I still need to add the bushing to one end, but it is otherwise done.  Tomorrow will be an off day, (except for cleaning the little shop again).

Thanks. 

I made up the hardware for the connecting rod this morning. 

I’m running low on parts now and it’s time to figure out what I want to mount the base and pedestal to.  I was considering putting threaded inserts into a piece of granite of using some Aluminum jig plate.  Any suggestions would be appreciated. 

Selecting of the color scheme is still open.  Suggestions?

Thanks

The recessed features of the cylinder got a coat of flat black.  Once dry, a 1/16” thick layer of cork was glued to the recessed surface and fit up with some 1 x 5 mm Mahogany, (lightly sanded and pre treated with Danish Oil).  Once fit, the lagging was lightly glued to the cork and another coat of Danish Oil was applied.  The straps are .018” thick Brass shim stock.  The features for the drain cocks are cast in a bad place for lagging straps, so I made straps that surround the drain cocks.  The first set of straps was .1875” tall and looked wrong.  The second set is .125” and looks more appropriate.

The lagging and straps look great, nice proportions!   :popcorn: :popcorn:
