Most pistons are cast from aluminium alloys.
The general term for piston is cylinder, and a cylinder might be made to work in this application. But a cylinder used in this manner, that is, a cylindrical shape connected in a machine that is used in the same way will almost certainly be called a piston by most investigators.
They are cast and then the ends are machined to accept a bearing and the pin that holds the rod to the piston.
The gasoline is avoided to go into the oil by few piston rings placed on the piston of the engine. Actually, the piston rings are made for this purpose only.
S&W never made a piston as far as I know.
flip the lever/switch again, it has both an on and off function *if you want the block to retract with the piston, you need a sticky piston
most auto mechanic preferred .002 clearance from piston skirt to sleeve

The Nitro piston is superior to the spring piston in design, but Yes, it can be converted back to a spring in most cases. It is best to have it done by an "air gun smith."
Mostly from cast aluminium.
Most piston driven planes are a direct drive, some have a gear reduction between the engine and propeller. But no transmissions that I know of.
Piston rings are commonly made from cast iron or steel, with coatings such as chrome or plasma molybdenum for added durability and longevity. These materials help provide a tight seal between the piston and cylinder wall, reducing oil consumption and improving engine performance.
most likely a valve is not seated,burned or 'missing'.. i.e 'dropped valve' this swopuld have made an obvious noise when it happened! if any of these are happening, the piston chamber will not seal... hence no compression.. another possibility is a hole in the piston itself ...
