[QUOTE="shivan, post: 247646, member: 194"] I have only recently started getting into the lapidary side of things and still have a lot to learn, but have recently refurbished a 10" trim/slab saw. From what i learnt, when you are looking at 10-14" blades you need to look more at oil as a coolant as water seems to only be effective for cooling 8" and under. The sump on my 10" is 100mm x 200mm x 120mm, though the 12" slab saw is much larger. I believe for a 10" to 14" you will want around a 1400 RPM motor depending on pullys, may need a little more for the 14"..... The clamp on my 10" is two metal plates with two small blocks of wood on each to hold the stone, then the plates have two bolts facing the saw blade and one at the back side with wing nuts on top to tighten them. The clamp sits on two steel rods running the length of the saw and a threaded bar in the middle which moves the rock through the saw by either pulley or handle winding. It is adjustable also by sliding towards and away from the blade, by the bottom plate fitting inside a sleeve and secured by two screws. Sounds like you have a good idea of what you want to do. Good luck with it. [/QUOTE]
