UTG 727 destruction

I can't bring myself to watch it.. but... hone for hours? as in sitting there with a drill and a bead or stone hone going up and down for hours? to achieve what though? if it was that bad it needed to be machined. was he trying to do a backyard .010 over?
If you find the junkyard jet video, they specifically said they honed the first cylinder for 8 hours...at Tony's "guidance" and eventually they did a "first start" video where it sounded like rocks in a can with major misfires. After that they didn't post anymore for a long while. Come to find out, the junkyard jet guys, tore it back down, took it to a actual machine shop and had it done properly. That's why tony ran them off, told them that's not what his channel is about.
