It's not that the tuners wouldn't all have fitted in line, it's that the edge of the baseplate would have gone beyond the edge of the headstock, leaving the fixing hole on the very edge of the wood, if not over the edge. It's the classic mistake.

The bottom line is he used too large a footprint tuners on his "vintage bass" and consequently had to spin one around. This has, to use his own title " improved it". Still don't understand how he "honed" the jack socket, surely that would make it larger?
