Finally got around to balancing my crank. For those of you that don't know how that works, First we weigh each rod and match all of them to the lightest one and same goes for the pistons. Then we make what is called a bobweight which mimicks the piston, rod, bearings and rings and put them on the journals of the crank. Then spin the crank in a balancing machine the tells you where and how much material needs to be added/removed. We can do a better job then alot of people in the area seeing ours is digital and has a drill press mounted on the machine which means the crank doesn't have to come out of the machine until it's done.
Here are some pics
This was the crank spun right out of the box. It was 61 grams out on the front counterweights and 57 grams out on the rear. The other numbers are the location to take the weight out off of the reference point.
Crank in machine
Finished crank. Note the decimal point. It is 4 and 5 tenths of a gram. I will guarantee that if the crank is balanced on an old analog machine it will never be this precise.
