[QUOTE="turnkey4099, post: 413483, member: 2122"] Back as late as the 50s, all saws of all sizes that I am aware of were gear drive and very low rpm. I doubt if any of them would have turned 8-9,000. The families first saw was a Mac with a 24" bar, gear drive and we even had the posthole digger attachment for it as wwell as an outboard helper handle. When I retired in 1976 from the AF I was surprised to find that there were no longer gear drives being made with very few exceptions. Harry K [/QUOTE]
