Advise on building a CNC table

[EddyCurrent]

Eddy Would the dross or what ever it is called stop the plywood from being flat on the table when fixed down etc. ..Clive

It's the logic of how I've read the statement;

i was looking at making the table so it can be used for plasma cutting with a water table.

or

put thick ply over the top of the emptied water table and use it with a router for woodworking.

So I read it as ;

Plasma and water table (not router) OR water table and router (not plasma)

in which case I did not take account of the dross from plasma and in fact I thought it would be very difficult to combine all three considering the mess a plasma would make to the bed/table
