Losenge-Valve Array Completed

[Mike Kirney]

I put it all together this afternoon. Sorry guys, no devices to limit valve travel. I couldn't find any half-round rod and I'm getting really impatient to try this out. I can always add it later, I have plenty of valve material. I left the sticky white pattern-paper on the front side of the valves just to see what would happen.

looks very nice there, good work!

Thank you for your encouraging comment, Stephen. I tested this new valve system and it didn't work. Leaving the paper on the reeds was a big mistake. Also, I found two pinholes in the weld joining the cone to the combustion chamber, so I think that might be part of my pulsation problem. I still have faith in the basic device, but I think I need to re-rivet the reeds so they stay closed before I turn the gas on. Bruno would have admired my ignition system. Rather than using a compicated welding sparker like last time, I used plain old book matches to light her up. How simple is that?

Mike, you are a man after my own heart. Next, we might try to build a chamber out of oak staves and iron hoops. With the throw-match-into-bunghole (TMIB) ignition.

Full round or pipe cut in half might work for travel limiting.

Full round or pipe would probably work just fine, but drilling it and riveting it in place would probably have been an aggravating experience, so I decided just to go without for the first run. My main goal right now is to actually achieve pulsation, then acheiving lengthy pulsation can come later.
