|Master Connecting Rod|
Mummy mummy, why am I running around in circles?Stu was asking where they put all the connecting rods on a radial engine. Here's a picture of a master connecting rod. Only piston #1 is connected directly to the crank (that's what the big hole is for). All the other pistons connect to the master connecting rod. That's what the eight smaller holes are for.
Shut up kid or I will nail your other foot to the floor.
Got that from the same place as the picture.
A connecting rod like this would require a two piece crank, which would only be suitable for an engine with a single row of pistons. Engines with multiple rows (like a Pratt & Whitney Wasp) would require a single piece crank and a two piece rod. Which is what my Uncle had. The top and bottom haves of the master connecting rod were bolted together.
