At last we have a reciprocating engine again.
Yesterday, pistons prepped with tinplate/tiewrap compressors, block ready with new gasket stuck in place with Threebond.
It took 6 hours over two days to get to this point. I'd get the block over all the compression rings, and it would persistently get stuck on number 1. After five attempts, which included checking ring radial thickness again, I realized that the 2nd ring on No. 1 had no shiny filed surface on the end - it was straight out of the box and had not been gapped at all.
That's what comes from working sporadically over several weeks. You need military precision on your record keeping, and to meticulously check & recheck what you did yesterday...
Here we have it all bolted down, with Threebond oozing out & Clay Jones shiny stainless steel nuts holding it all together.
