plasma cutting table

Hi all,

My current desire is to make a plasma cutting table.

I know that these are similar in design to router tables and I assume
that there are a few in this group that have made these tables.

If you have any pointers, I would greatly appreciate your input.

My intention is to cut 1/8 and 0.08 aluminum sheets

Some of the concerns I have are:
how fast to I need to move the table,
how messy the process is, does it create splatter like torch cutting.
does it reak havoc on the slides ?
How large of steppers should I plan on using ?
and how you move the table, single center lead screw ? twin screws on
the outside linked by a timing belt ?

Also, if you do have one, do you make parts for people ?
