Another set of questions not all related to each other.

  1. How important is the base the OX is on? I had to move mine temporarily to the garage and it’s sitting on a piece of plywood across two sawhorses. There are 2 layers of 5/8" MDF as the spoil board base and neither are fixed to the machine at all other than just laying on top of the supports - is this going to give me extra vibration that will cause part of my issues (I am 99.9% sure the answer is yes)?

  2. How do you guys use cutting oil on a MDF spoil board? Doesn’t it just soak in and destroy that area in one cut (once it gets damp it swells)?

  3. I used rubbing alcohol when I tapped the holes during construction and read that it’s a great lube/cutting oil for aluminum - but isn’t it flammable (as with WD-40, kero, etc)? If the bit gets hot enough to smoke, how do they not ignite?

  4. I’d love to use some kind of auto-spray coolant but I’m worried about the spindle being exposed as it is - is the 400W spindle sealed?

  5. Has anyone ever setup a non-spindle spindle that uses a regular larger motor on backside of the X gantry with a belt to the non-motorized spindle on front?

  6. Is it possible to do what I described in #5 and keep accuracy without having to buy the $700 liquid cooled spindle if I want more cutting power? (Or do I just go up to a regular wood router?)

I am also very curious about questions 1,2&3. I haven’t taken the jump to aluminum yet but plan to soon I hope. I’m sure bit type and coating is also very important to proper cutting.

Anyone have a chance to think about these questions? Still curious if anyone has answers.
