6-cylinder radial steam engine plans done and uploaded

[crueby]

Just finished a new 6-cylinder radial steam engine - my own design, with a 1/2" bore and 1/2" stroke. I've built a number of kit engines (Stuart, PM Research, etc), and this is my first foray into building from scratch. I've always been intrigued by radials, and thought it would make a great project. Turned out well, even with the many many tedious disassembles/reassembles to get it right!

I've drawn up plans for it, and posted it with a build log up in the downloads section (plans are at the end of the log). Thanks to those who replied to my query last week about software to draw plans in, as well as all those posters I've learned from!

I've gotten so much great info and ideas from others posts, thought it was time to share back!

That's pretty awesome!
How much could someone buy one for?

 

[crueby]

Plans are free, so material and lathe/mill and your time is all it takes... ;D

I make these for fun, not profit, never considered selling.

It seems the plans and build sequence are missing from the downloads section.

I was interested into reading the build log, no traces of "radial steam" or so in all the 25 pages of the download section.

I just looked -its there on page 21 of the downloads section, titled 6-cylinder radial engine build log.

The downloads area is not the easiest thing to search, but it is there.

 

[mzetati]

My bad!
And I checked the download pages twice.

Thank You
Marcello

Could you explain how valves work? I can't imagine it. Maybe you can attach some drawings?

Could you explain how valves work? I can't imagine it. Maybe you can attach some drawings?

The valves consist of a rod that is a close sliding fit in its hole, and the rod has two narrowed down sections that connect the piston to the air/steam inlet at the top of the stroke, and connects the piston to the exhaust at the bottom of the stroke. Rather than have an exhaust tube, the valve rod just extends out the top of the block, connecting the piston opening to the open air.

Thank you, now everything's clear. I'm going to build one.
Unfortunately I have only lathe so I'm going to make crankcase from hexagonal bar.
