I saw some sliding tray saws which look pretty good, but they don't seem to allow for different depth of cuts, just straight through the rock, no way to take multiple passes at the rock cutting deeper each time. I'm not sure which way is best, all through in 1 go, or multiple passes? Doing multiple passes sounds like a recipe for lots of scratching. Remember big blades are for big rocks. No need to go a little at a time. Even with gravity chop styles, the blade cuts all the way through in one pass. A good slab will be smooth as possible, done with the right size blade at an appropriately paced feed rate no matter if its fed by hand or machine.

Getting much closer to finalizing my design now. I am curious. I see some factory made saws use rather large axles, for a 24" saw one company used a 1 & 3/8" thick axle to run the 24" blade with a 1 inch bore. Is this enormously thick axle necessary? Would a 1 inch thick axle work instead or would it bend and wobble over time? One pass one level kerf. Multiple passes,multiple levels of kerf. Cut is slow, like a metal cutting handsaw. As it should be.

Thanks guys. I see it is better to make 1 pass to reduce scratching. What about this question? Can I use a 1 " axle for a 24" blade or do I need to go with a 1 inch, 3/8" thick axle like highland park? Getting much closer to finalizing my design now. I am curious.
