well, I finally have success with an engine. some may remember my failure a while back with a bj cicada that I never could get to run. I decided to back up and try something easier. I decided on elmers #25 wobbler. an I have success.
I learned a few neat tricks along the way, like using locktight to combine duplicate parts ( I made 2 engines) so I could cut and drill both at the same time then heat to separate. I learned that broken drill bits can easily be removed from aluminum using boiling water and alum from your spice cabinet. it disovled the bit without hurting the aluminum - that was pretty awesome.
I left the shaft a bit long so I could add a pulley later and did not angle cut the sides of the cylinder because for some reason I just don't think that looked good. I might cut a radius or round them over but I didn't like the 45deg angle cut like the plans showed so I left it square for now
I have a video, just need to figure out how to post that to. its running on about 15 psi just using a blow nozzel according to my junk regulator
