    As promised, here's the plans for the double acting V-Twin steam engine to which I've been working.

    First are the PDF drawings (probably a couple of posts to get them all in here)...

    Here's the .zip file of the CAD model. Uncompressed it's in STEP format.

    Now for two of the casting patterns (.stl format).

    Ved, where is the first thread you posted on this engine? I seem to remember that you said this engine can be made with bar stock. I looked at the cylinder in the plans and I don't think I have the expertise to make the cylinder out of bar stock yet. If I'm not comfortable with bar stock, it looks like I can buy the castings that you posted in the plans. Are the prices for one piece? And forgive my not knowing, but is the cylinder one piece if ordered or two halves?

    I haven't got to the point of offering the castings for sale. In fact I haven't yet done analyzing what I'm going to charge. The cylinder is the most difficult part to make without being a casting.

    To make the cylinder without a casting would be brazing two pieces together or a much larger chunk of material and using a rotary table mill out what isn't a cylinder.

    Please be patient and give me some time to come to a cost on the parts. Again, I don't intend to gouge, but I do need to recoup my costs. I'll eventually post the casting prices on the buy/sell forum when I get to that point.

    ...Ved.
