Thanks, Zee, Jim, Dave.

Spent most of the day in the shop today.  I had to change the type of valve in the head.  Didn't have much room, so the valve assembly had to be pretty small.  Didn't take any pictures of the new arrangement.  However, I do have the engine running quite well now.  Here is the video!

I had to fiddle around quite a bit with different springs on the slave valve.  I actually learned something new about it today.  In the past I had just depended on the spring to stop the ball slave valve at a reasonable distance and return it when the inlet valve closed.  However, on this engine, the channel with the slave valve is quite long and so, necessarily was the spring.  Unfortunately, this caused the engine to run eratically.  So, I installed a pin which stops the ball slave valve, threading it so I could adjust the travel.  Works great and greatly enhances the way the engine runs.

Great job Chuck!!  You are the king of the air engine. A modern day Elmer in my eyes. I just love the projects that you choose. Keep it coming.

Another beauty. Congratulations Chuck.

How many engines have you designed now? Have you released drawings for the V-8?

Very nicely done indeed Chuck  :ThumbsUp:

It starts a lot easier than the original  ;)

Kind regards, Arnold
Building an engine takes Patience, Planning, Preparation and Machining.
Procrastination is nearly the same, but it precludes machining.
Thus, an engine will only be built once the procrastination stops and the machining begins!

Thanks everyone for the kind words.  Really very much appreciated.

Kevin, I've built probably close to 30 engines, 20 or so were my design.  I've started another 3 or 4 that never got completed.

I uploaded the plans for the V-8 to HMEM.  I tried uploading them here, but kept getting an error.  Never got a response from the Admins as to why, so kind of forgot about it.  Guess I should try again.

Chick, you mentioned 120 psi in the video...why so high...is it to do with the type of valve? It really sounds great though!!

I tried again and I keep getting an error message saying the upload takes too long, might be that the file is too big, which is about 3 mb.  How can I get the plans to you, Dave?

Bill, the engine will run on a lot less than 120 PSI.  Rather than adjusting the speed with a pressure regulator, I just use a ball valve and control the air flow rate.  When I mentioned wide open in the video, the ball valve was in fact wide open.  The goal of my designs is to sound as much like a gas engine as possible and higher pressure seems to give me that affect.  I could probably speed up the Lister D significantly by advancing the timing.  Right now the inlet valve begins opening around 20 - 30 degrees after top dead center.

Although the pressure on the Lister D when the ball valve is full open is quite high, the actual rate of air flow is pretty small, relativel speaking, because of the small inlet valve and the low rise.  The valve also seals pretty good letting almost no air through when the valve is closed.  I'm hoping it will get even better when engine breaks in some.
