EPO - A Super-Simple Oscillator

Well it works ok. It runs on next to no air (below zero on the compressor scale) but doesn't go extremely fast when turned up to 10PSI. My gut feeling is that the ports are probably a bit too big: I didn't do any drawing or calculation just blindly followed the plan. I don't see that putting the pivot at the end makes any real difference and it's pretty boring to watch  The best thing about it is it's airtightedness (made that word up), I can't hear a whisper leaking out anywhere.

It needs a wooden base and I don't like the hex socket screw so I'll replace that with...something and maybe tart up the flywheel a bit. Really need to get a knurling tool to make a nicer adjuster for the pivot.

Made a new pivot, not convinced it looks any better but it gave me the opportunity to practice grinding and using a HSS form tool for the roundy bit.

Yes, it looks good and is running very well 👍.

Another working engine .......and so quickly......well done Paul 

Running great Paul! Sounds a little like a sewing machine. ie smooth but mechanical.

Thanks for the comments. Good audio spot Steve, it does sound like a sewing machine doesn't it? (The noise at speed is from the tile it was sitting on).
