Degree wheel for port timing
 

I have never had to use on of these before. I just used a rotor I machined out a slot in to create my porting. But i am doing a PP motor right now and would like to place the peripheral hole correctly by measuring the port timing.

I have read a few things here and there on how to use them, but everything I find is pretty vague or so over explained i get lost. Anyone want to make a short how-to video on using a degree wheel and post it up?

i can show you tomm when i come to pick up the manifold

I would also strongly suggest you read some of Lynn.E Hannover's posts on nopistons.com about the proper port timing procurement methods.
