Finally bought a blade for my refurbished B&I 10" Gem Maker, and went with the MK-303 .040 10" blade. I'm running the blade 1:1 from a 1725rpm motor, which is at the bottom end of MK's suggested RPM (1720 - 2290).
My question is, how fast should this blade cut hard material ~mohs7?
My first / only cut was an oblong jasp-agate, approximately 3" long and 1.5" thick. I mounted the rock in the clamp with the longer side facing the blade (pretty sure that didn't help). The B&I has a gravity feed and I had 1.5 pounds of weight on the line. The cut went smoothly but took around 90 minutes ... is that normal?
The only saw i have for comparison is a 7" tile saw rigged with a 10" ceramic blade, which would cut the same stone in a minute or 2. I realize the tile saw will cut much faster but it seems maybe i'm doing something wrong to have it take soooo long.
Would increasing the RPMs make a significant difference? Do i need to add more weight? Am i just being impatient? Any tips are appreciated.
