I am considering a 14" wood/metal bandsaw to be able to do some metalworking but I a newbie when in come to metal. I like the Grizzly G0621X which as a 150-3000 variable speed range but the 150 rpm is higher than some speeds I see from charts. I am also considering the Jet wood/metal BS which as slower speeds but is not variable speed. Can I compensate with a slower feed rate for metals which should have lower speed rates with the Grizzly or should I go the Jet? Any other candidates I should consider? Thanks.
