My first engine.
This is the first engine that I built.
I had the kit lying with me for more than a year but I was afraid to touch it.
Mainly the imperial dimensions were giving me a scare.
Faced many challenges mostly due to my inexperience and lack of tools and fixtures.
I learned a lot building this engine.
Now that the engine is finished I don't have any means to run it. I am looking for a small air compressor to buy. It turns freely by hand so I am fairly confident that it should run on air.
Now next job is to paint it and mount it on a wooden board.

Regards
Nikhil

Nikhil,
Very nice, looks like you did well on the PM 5 especially since it was your first build. I built one a few years ago and once I got it all dialed in it really runs great.
It will run very slow on just a couple pounds of air pressure, nice and smooth. Congrats and hope to see it running soon.

Some of my setups

Drilling main bearings

Machining crank pin. Crankshaft was machined between center. Sorry no images.

Machining cylinder bore in lathe.
Hardest part was machining the inlet and outlet slots. The operation was done blindly in mill with cutter out of sight. I was watching my dials and praying that nothing bad happens.

Machining the frame.

In hindsight I could have done a better job.
I have a PM #1 castings kit and will attempt that next. I am watching ongoing YouTube series on machining the kit.

Nikhil

Well done. Congratulations on your first build. I gave one of my machines to a nephew who is working on his PHD in AI Robotic Computer Programming. Computers doing all the work for you. I gave him this message, "No CNC machine will ever give you the same satisfaction as getting dirt, grease and oil under your fingernails and building something with your own two hands"!!!

I got small airbrush compressor from eBay for $99 and it runs all of my engines so far.

Ahh...

You get to have the initial joys of fiddling the the valve timing. If your experience ends up like mine, it'll be about a hour of fine adjustments then all of a sudden the thing jolts to life. Then you'll try to improve it and screw it up.

A junked refrigerator compressor will silently supply compressed air. Make a trap to capture the oil and return it to the inlet.

If you can get access to a co2 cylinder and a regulator you can run the engine, I got my regulator from the Coke man free and used a little co2 from work
just to test a engine or two..

Looks great!
A car spare tire will run it for a while with the right fittings.

As for air compressors, they're Chinese made, but the brand "California Air Compressor" has units that are very quiet (e.g. 65db) compared to most rattletraps sold to consumers now days. I have the 10 gallon version and yes, you can actually have a conversation beside it while the compressor is running. You won't be talking in hushed tones, but you won't have that urge to evacuate the room until the thing shuts off either.

An American made pump from GAST (about $600 for the compressor, no tank) is also very quiet. The company for whom I work uses them.

Thanks for all the inputs.
I am thinking about using a tyre inflator type compressor to run the engine.
Now its Diwali time in here.
I will try it after the holidays.
