I follow you. I a little bit of a balancing act getting it set up but should work fine. Thanks! I bought a dial indicator and magnetic base today at Harbor Freight. I sprung for the digital to make life easier on myself. I'll look into getting the degree wheel from Crower tomorrow since they are about 15 minutes from my work. I set the indicator up on the deck to measure the piston going up and down for kicks. I think TDC can be determined without using a piston stop. If I start with the indicator loaded on the piston sitting in the hole about 3/4", take the indicator and degree wheel measurements, turn the crank until it hits TDC and returns back to the same indicator measurement, record my second degree wheel measurement, add the two and divide by 2, I should know where my TDC falls on the degree wheel. Seems like this is the same principle except I'm using a digital read out on the dial indicator instead of a physical stop. The only problem is getting it to return to the exact same reading with the rings in. I think I may be taking my pistons out for the 3rd time, ouch! Actually, it seems easier to just set the dial indicator in the bore and turn the crank until you find the highest reading. That should be TDC. Again, it seems the only way to do this and have control/accuracy would be with a single piston, no rings, i.e. minimum drag. What do you think?
