Hello everyone,

I started this engine over a year ago and am now just finally getting around to getting it going. I would like to blame many things for my rate of progress, but it just comes down to procrastination! Their always seems to be something else to work on or fix.

I posted some of these pictures on another forum, but to refresh your memory I'm re-posting them here since as I said it's been over a year ago I started this thing. The whole idea was to use a 2 1/2 pound weight from a barbell that I found at a scrap yard and design an engine around it.

I started with a wooden pattern for the base:

I cast that in aluminum:

Made a few of the parts - crank axle, counter weight, cylinder, piston, and rod:

Here is where I got stuck and put it aside till a couple of week ends ago. I got tired of looking at it lying dormant at the back of my bench so finally took a couple of days figure out the valve and valve train and got it working!!

It's funny how you put things off.. This has turned out to be a very fun project and it is satisfying to see it running after all this time. It turned out better that I planned - even though I made it up as I went along. ::)

Here it is running:

Well thats great, well done on getting a runner :clap: :clap: :clap: :clap:

It ticks over very nicely at a slow speed, and I like the sound of it too.
