Hi,

On the spindle, have a good read up, a lot of the spindles perform badley at below 10,000 rpm, you loose the touque ,

Our machine sizes are very similar, i have discounted R&P for stone, due to the gantry waight required to keep it in position, and the motors or servoes required to drive them, i leart loads by asking question on here,

With water, i just ment a large container under your machine,

I haven't started yet as its always better get as much info as possible.
am really glad i stopped myself buying bits before i got some of the answers on here. i will write up what i have learnt in relation to stone, over the weekend.
