I still need to polish the bright work and paint the rest. (I will do that in the spring after tax season). There is lots of little parts on this one. The castings are from http://www.pmresearchinc.com/
It runs great on both steam and compressed air. It took me a year of spare time but I think that was because I played golf three days a week this summer! http://bbs.homeshopmachinist.net//biggrin.gif

Nice looking work PHiers. At one time, I almost bought that kit, still may. It's a nice looking engine.

I think I'd have a hard time covering that beautiful bronze with paint though.

Looking good to me!Are the castings as good as they look?Any pores or voids?

Somebody gave me one of the're oscilating engine kits,little bitty engine in zamac castings.It sat in my drawer at work for a year before I hauled it out and built it,took about 4 hours including paint(it only had eight or nine parts,not nearly as many as in your engine).

It was suprisingly relaxing,that's what got me hooked on model building besides making chips 9-5.

That is a nice looking engine. I agree, the brass looks better than paint on a model.

Let it age and develop a patina.

I wonder what they called them before the coke bottle? Or did they call the original coke bottle a steam engine shape?

These bronze casting are very good. No voids. Just the PITA of cleaning up the flashing! http://bbs.homeshopmachinist.net//biggrin.gif

Not being a "real machinist" it takes me lots longer! I probably only had maybe 50 hours of "real work" into it.

LOL, I did that one too, it was semi easy, even for me!

I think pm research calls them that because they look like a old time coke bottle.

I may yet decide to buff it up instead of paint, I agree the bronze looks nice.

Thanks guys for all the nice comments, I appreciate it!

Hahaha...yep that's the one,mine's about wornout from running on air.I showed it to my then girlfriend,I think she was jealous when she asked"okay,but what does it do?"

I think I may make it"do" something just to show her what it does http://bbs.homeshopmachinist.net//biggrin.gif

BTW,did you know that once broke in they will run 3,000 rpm+ on 125psi air? http://bbs.homeshopmachinist.net//biggrin.gif

Beautiful work Paul. Are you going to take the little beauty to Cabin Fever?

Cecil,
No cabin fever for me. I own a income tax service, guess what I will be doing in January? http://bbs.homeshopmachinist.net//mad.gif

I hope to get to Iron Fever in August tho. http://bbs.homeshopmachinist.net//biggrin.gif

I have 6 engines done I hope to bring.

Weird, want to tell me how you know that? http://bbs.homeshopmachinist.net//biggrin.gif

Why stop there, why not try compressed nitrogen? http://bbs.homeshopmachinist.net//biggrin.gif

By the way, nice looking work on the engine. Weird, do you have some pics of your engine?

Always good to have a"before" picture after something comes unglued http://bbs.homeshopmachinist.net//biggrin.gif

Little thing for some reason has developed a bit of a rod knock http://bbs.homeshopmachinist.net//biggrin.gif

Heavy drinker huh? http://bbs.homeshopmachinist.net//biggrin.gif http://bbs.homeshopmachinist.net//biggrin.gif

I spun it up a few times,need bigger ports to get more cfm through the inlet.

I might even balance the thing,the crank counterwiegh isn't heavy enough to offset the brass piston so it vibrates badly above 1800 or so rpm.

I'm still thinking of "something" for it to do,maybe incorporate it into an air tool of some sort,that'll show her what IT DOES http://bbs.homeshopmachinist.net//biggrin.gif

I ran across site for adding patina/color to bronze & copper you may be interested in. I havn't tried any of these, so best try on some scrap first.

Tool black works quite well for the iron & steel parts.

neonman, thanks for the url. I might try one of those. As far as tool black goes I have some of that, but on this engine the only steel is the crankshaft the eccentric (sp) for the valve rod. Everything else is brass or bronze.

Oh, and Happy New Year all. http://bbs.homeshopmachinist.net//biggrin.gif

Paul, Great job. You are a few steps ahead of me. Mine is still in the box (and has been for about 5 years).

PolskiFran,

I know how the works, I have the casting set for the Stuart 9, been sitting there for years now. I think I will start on it right after tax season ends. (of course I said that for about 5 years now) http://bbs.homeshopmachinist.net//smile.gif
