red, i am by no means an expert.

but we flat out abused a skilsaw..worm drive. we put a diamond blade on that thing and scored a driveway. then we used a rental Bosch jack hammer and busted it out of there. as soon as the concrete started breaking up, it went pretty quickly. our scoreline with the saw wasnt very deep. 1/4"? but the final product..we got a pretty clean line.

i'd get fitted with a half mask respirator if i were you. this is gonna get dusty. i bet if you had a friend following with a shop vac, you could keep the dust under control.

can you farm out the saw cutting?
