After several phone calls on Friday, I was able to make contact with the ring people, they told me all several of my cast 2d rings were bent. All my steel top rings were fine. They are giving me a set of 1.5mm 2d rings made to my specs. They are sending my cast 2d rings back and told me I could try and take the bends out. They are charging me only for 2d day delivery ($31.50) for everything. Seems they are trying to make things good.

I don't know how you bend "several rings" and not all. I am not the brightest bulb on the tree and I may have inadvertently "bent" them while installing them on the pistons, but don't see how. A .8mm ring with a .130 radial thickness, is like a well done straw of spaghetti and installing it on a piston is effortless. I did have these rings on and off about 2 dozen times while I was lapping the spacers (at their direction). They(rings) were sticking from the first installation.

Hopefully I will receive my pistons and rings soon so I can renew my effort to finish the motor.

Thanks again for the advice, it is surely appreciated.

Use a ring expander instead of spreading them by hand.
