A little machine work

[Smoke]

Hi fellas, here is a Curtis Compressor Pump that I am turning into an engine. I made the complete head out of 4" round stock. Turned it down and cut/milled the combustion chamber. Made the valve guides etc. I turned the crank end to put on the crank gear and made up a shaft for the cam gear. I am working on the pushrod assembly now. I will then figure out if it will be made a hit & miss or a throttler. The engine has great compression and the valves seated well after I cut and seated them. Nice fun project. Hope to get it to run this fall.

That Looks like a really Nice project. Keep us posted on the developments These always intrigued me when I seen them. But between all the pasasites breaking their machinery and wanting me to do things I never have found time... Maybe Next winter....

What're your plans for a flywheel?

That's a great looking little project you've got going! What are you using for a camshaft? Did you make one or salvage something? As far as a flywheel goes - I saw one where a fellow used a couple of disc brake rotors. Must have been from a truck, they were pretty big, but it looked pretty good. He had 'converted' a Briggs & Stratton Model FH into a little hit & miss. He cut down the crankcase exposing the crank & rod and had the whole thing laying horizontal on an oak skid with a battery & coil in a box underneath.
I'll put a couple of pictures up of a different kind of engine project I have going. Look for my "Air Engine"

Hi fellas, as far as your questions, I plan to use the original flywheel from the compressor, it is fanned to throw air to the cylinder. The cam and gears came out of an old reo gas engine that I had for parts, perfect 2 to 1 ratio.

One more question came to mind -
What are you going to use for ignition? Battery & coil or magneto?
Here is a little (Very little) engine project that I came up with at one time. Formerly a model airplane engine, I made a base for it and adapted a flywheel magneto from a weed whacker to fire the tiny spark plug.

Idle time on my hands and machinery to work with can be a dangerous combination!
Have fun,

John, Nice work on that homemade engine contraption that you have there. I like that magneto/flywheel setup that you have there. I plan on using battery/coil ignition. I also just found some plans on building a mini magneto. The plans look a little confusing but I might give it a try. A little more advanced machine work than what I am used to. Nothing better than making things out of your head and getting them to run. It keeps our minds creative. When I was a kid, I once blew up a tractor tube with helium and strapped a small battery with christmas lights wrapped around it and let it go. I must say, I had the neighbors going UFO crazy for a while. My pop found out about it and I got the belt for that one. I was young and didnt understand what he meant by a jet airliner sucking that tube into its engine and crashing.
