i didn't buy the stand.
the cheap ones they have seem not good quality to me.
i only bought the ib/e grinder.
and i really like the tool.
it is superior to all other minidrill grinder tools i have.
if the tool runs rock solid centered it is much better to grind, cut, etc.
also the motor is very powerful and very silent.
i have a unit which has also 100W but seems to turn that only into heat.
what i dislike at the ib/e:
the button for spindle stopping (tool change)
can be pressed while running, it is at a exposed position.
this could be done better.
a cnc machine would be nice but i don't have the tools to make it (and
don't want to spend too much).
if i would have to build one i would use linear rails made with ball
bearings (use 3, one pring loaded with strong spring).
and for moving i would use metric allthreads and stepper motors.
for parallel moving of the "bridge" in one direction i would use two
allthreads, coupled by some toothed belt, chain or so to move
simultaneously (or two motors - take care that both turn!).
the problem for me would be making the software. i hate making this.
also the mechanic things would be easier if i own a milling machine and a
lathe, but i don't.
also i would have to find precise rails which offer three very straight
sides (like a pipe or so).
i heard there are extruded aluminium sheaths which are precise enough for
this but i have no idea if this is true / where to get.
but this is another story....
