is the piston connected to the connecting rod? i have an old air motor similar to this and when air isnt applied the piston doesnt turn by hand turning the crankshaft
In the video I was using a small (~250ml) bottle that came with it, but the end cap split. Made my own 1L replacement bottle (doesn't fit on the car!):
Cut the valve out of a bike inner tube (schrader / car type valve is best), drill a hole in the lid of a fizzy drink bottle so that it just fits the valve. Cut the rubber around the base of the valve down until it has a shoulder that just fits inside the lid. The pressure holds the valve in place, but you can glue it in if it's leaking.
so the holes drilled in the side of the barrel are the air escape ports ? and with motion the piston lifts back up? if this is so wha tcontrol the air input?
Yeah there's about 6 exhausts (2 small ones). The crank has no "little end" - it ends in a ball that pushes against the piston head. The piston is pushed up by the crank on the return stroke. Air is let in by a small spigot on the top of the piston which opens a rubber ball valve in the top of the cylinder.
is that the RAID engine or RAID II engine?
