Alright, so I bought some Autolite 104 coppers that I'm going to put in. I want to gap them at 0.055. I have the gapping tool that has the rings on it. Unfortunately it doesn't have 0.055 and goes from 0.050 to 0.060. How would you guys go about gapping it to 0.055?

I made it so that 0.050 goes through the ring no problem with a little bit of room, but yet small enough so the 0.060 goes in a bit, but cannot pass through. Is this the common way of doing this? Or must I buy a gapper with a 0.055 on it?

Thanks
