Some parts from other, well the term projects does not quite fit. 3/8ths bore about a 2 cm stroke. I do not have a compressor handy to run it. However I tried to keep the tolerances fairly tight. If you hook up a hose and blow REALLY HARD you can get it to run a bit..... then you pass out. Time to find a small compressor and send it with the nephews to school.



(Yes I know.... another wobbler. I gotta start somewhere. At least I built it without plans.... and it shows.  :lol: )

Nicely done. I hope the one I'm about to start on goes as well as this.

BiggerHammer:
The main thing that helped on this was getting a set of reamers  :dremel: and chucking up a wooden dowel rod to lap the cylinder wall. I then put a bit of brasso on the piston and cycled it back and forth by hand rotating it to insure smooth operation.

Those are some nice wobblers there snoopdog. I think I need a bigger drillpress not quite enough clearance for big stuff. The kitchen is getting a bit full though. So many tools to buy, so little spare cash and room (hmmm I don't use the living room much...)

Oh, by the way the nephews were THRILLED with the engine. Now to  :proj: something new. Figure out how much I can do with what I have. That being an 8 x 14 lathe and a smallish drillpress and limited machining skills. This shall be FUN!

The neighborhood kids all love my engines, and even ask me to get them out and run them once in a while.  Children are fascinated by the moving parts - which makes us all big kids, right?
