Holes need tapping M3. 4mm and 3mm Bar is cut with a die are needed for the slide and piston rod.
Crankshaft is pinned through with a 2mm rod to prevent bucking, this uses a 3D printed drilling guide.
Sand/File the Piston to fit the Cylinder. It should be a snug fit.
It does work but requires a lot of filing and tuning of the wobble engine.
