I am working on my baffles and it is asking me to use the bending bar to bend the metal. I suppose this could be a piece of wood with a 1/8 dia radius.
Just wondering where this is defined in the plans.
This is for the IO-360 engine. I did the bend after I fitted most of the baffle. On my engine, I just bend by hand until it fits between the vertical baffle and the forward ramp.
