Hey Scott

For what it's worth.....

I faced this same problem when building my RSR spec motor for my clone. I could not get consistent readings using the solder method.

I ended using the depth gage feature on my digital calipers to measure the distance from the seal surface on the cylinder to the lip along the circumference on the pistons. I used a dial gage to ensure I had TDC and measured at 4 different locations along the circumference of the piston. I was able to repeat within +/- 0.1mm using this method and got deck ht data that made much more sense than the solder method.

Good luck and I'll be following your thread.
