That's a good link Jason - how do you find them 

Enlarging the image it as you indicate it appears to me that the flywheel may have been plated? It certainly gives that appearance in the area closest the camera.

Chuck - what size are you intending to make your flywheel plus the bore and stroke? I note the one that Jason has linked has a 15.5 inch diameter wheel - if brass/bronze that's going to be one expensive part 

Very interesting design - a good start and looking forwards to how you tackle it further

The bore and stroke are 0.56" x 1.5"  the cylinder is .875" OD and 2.25" long, exclusive of cylinder covers.  The overall height of the cylinder assembly with both end pieces is about 3.5".  The flywheel I'm planning to use is about 8.5" diameter, cast iron, from a Sanderson Beam Engine.  I know that seems big but in drawings, the proportions look nice, since the flywheel has thin spokes  and a pretty thin rim.  Here's a picture from my drawings in Visio.

I followed Crueby's directions and I think the soldering job came out good.  Still letting it cool down. 



The flux I used is Stay Clean paste.  Seems to work really well.

It's a very interesting model.

Thanks Chuck

Well, not bad for a novice.  I'm pretty happy with the way the soldering turned out.  I can see the solder around all the edges, so coverage appears to be good.









I may have to rethink the flywheel.  Might look different with the engine frame, but in this picture it looks a bit large...

[crueby]

Nice!

Chuck, your Sanderson flywheel is more likely 10" diameter the one I used on an engine was and that may be why it look bigger than the 8.5 on the drawing.

Ramon, the columns also show the same finish, maybe they plated the castings to make them look more like the solid brass, did think it may have been a lacquer to stop tarnishing that had flaked off but plating looks more likely

Chuck,

That doesn't look to far out in relation to the original model to my eye - I'm sure once you have it on the frames it will look right.

Jason - the more you look the more you see  it appears to be composite on some of the 'brass' parts. It was a beautifully made model for the time - there's a lot of work in those spokes if it's a casting for sure.

Watching with a high degree of interest as to how this turns out

Chuck, seems like I always learn something when I follow your projects.  Did you make those wire clips you used to hold the block to the cylinder when you soldered?  What are those?

Following along with interest.

That flywheel looks like what I'll need for the Muncaster.  Let me know where you got it and if there are any more available.

Martin's Models don't have any that size that are thin.

[cfellows]

You're right Jason, that flywheel is about 9.5" diameter.  Might be able to take a little off the diameter, but not much.  I have another cast iron flywheel that is about 8.5" diameter but is thick and heavy.  I'd have to do a lot of machining to get it thin looking like the Maudslay.  Unfortunately, milling one from solid out of brass would cost hundreds of dollars.  And assembling one from pieces, like Don did on is Benson engine, is probably beyond my capabilities.

Rudy, I made those clips out of some .040" music wire I had laying around.  Just used a couple of pliers to bend them into shape.

kvom, I acquired that flywheel in a set of castings for the Sanderson beam engine 15 or more years ago.  Turned out the cylinder casting was unusable so I never built the engine.

Beautiful work Chuck. That cylinder looks great!!

[cfellows]

Thanks, Bill. 

I got the holes drilled and tapped for both cylinder end covers.   Don't have long enough screws for the bottom cover, but they are on order.



Next I'm going to tackle the engine frame since that is the most challenging part of the build.
