Hi to all. Quite some time ago I posted my C_Thru Oscillator . It runs pretty good for a single acting engine, I wanted to make one to run on an aquarium pump. Double acting seemed to be the way to go. I also used Enco radial ball bearings for the crank and some brass sleeves on the cylinder pivot. Big improvement. I started to build two of these engines in November, planning to have one for a Christmas gift, and one to keep. Ya right. Here's a pic I took today April 6, of the mostly completed parts of one engine. It's got 1/2" bore and 3/4" stroke. The mains shafts are 3/16 drill rod, the hex head brass bolts are 2-56 purchased at hobby store, the rest is all home made, mostly 6-32 threads. the connecting rod is 3/32" drill rod, threaded 2-56 and the big end has a bushing 5/32 OD X .086 ID. Lots of fun making this stuff.
Today, I decided to get one going, took about four hours and got one together and running. Two photos.
The video I took came out like ...bad. I'll try to get something posted soon. Need to get the other engine together and bling them both up some, that will make me happy.
