This year at World Con, I am on a panel about weird tech. For the panel I am building a steam engine.
Here are a few photos.

The first fitting of the crank shaft.

Test fitting the end plates.

You know it is getting serious when paint appears. The crank shaft mounted and aligned.

It is a steam powered V-6 for a panel at world con.

here is a vid of it running at 1200 rpm

The thing is almost done, I have had it turning on the lathe for three hours now, it pushes around under very little pressure.

Kevin

That is one lovely but strange bit of work; congratulations!

What a brilliant, inspiring piece of work--well done! I especially like that the heat source is removed from the release mechanisms for a change, which means that any variety of fuels could be accomodated (including wood). You've overcome two or three failings of the last production steam cars from eight decades ago with your version.

We (my wife and I) write for the Grantville Gazette. Every year the authors in the 1632 story cycle meet, and attach a 1632 track to a convention. Two years ago it was NASFIC in NC, last year it was DragonCon, this year it is world con in Chicago.







The schedule is as follows. (Thanks to Rick Boatright, Ed board, GG)

As you can see it is a busy list of events, I am on all the weird tech panels, the writers round table, and maybe as back up on the airship panel, and waste water panels....



Snerking the plots is Eric Flint telling us where the story cycle is going, so we can avoid tangling the thread of narrative.

Kevin

Wow, what a busy schedule. It sounds pretty interesting.

Eric Flint's 1632 is pretty neat, and I guess I'm not surprised a fandom has arisen around it.

There's a thread about people going to Chicon 7 (http://www.absolutewrite.com/forums/showthread.php?t=247930), if you'd like to drop a mention there.

In other news, I have been working on my "fly wheel" Balance has been hard as the wind makes it rotate, instead of stopping with one blade at the bottom.
Any way here are some photos and a video, in the video note how the accursed thing accelerates....


Here is a complete engine,

Here is the fly wheel, made from a 2x4 with hand tools and an orbital sander.


Done by eye no references except a memory of seeing a wooden prop hanging on a wall.

Here is a video of the balance process, and the interference by the wind. (about 4 mph+/-)

Have fun,

It has been fun, and time consuming.

Just for fun here is a paper on the steam source I want to make for the engine.

http://www.steamautomobile.com/northea/lamont.html

The biggest problem this engine has, is that it will run just as well counter clockwise as clockwise....

For an airship that is okay, alas a ground vehicle usually has to reverse rapidly, and that takes more involved valving. My engine looks like this, in the valve department.

The drawing is simplified, but mostly complete.

Kevin
