only thing you need now is some outlets mounted in the table, thats how the one i use outside is, it has a small drop cord plug to hook a drop cord to and the wire ran into some outlets mounted underneath or in the 2x6's and your good to go
not many ppl think of the simple shit till there done with the job lol, i worked i dunno how many hrs on something and having to unplug a drop cord and hook up a saw or drill or something is a bitch when u want to get it done, i have cordless tools but sometimes its better to have a corded one
and a pro about it is once u make these mobile all u need is one drop cord maby 14guage or 12 and u can run it to your table and move your table around and still have outlets ready to go, with how big ur table is u could put 6 on it with no problem, 2 on front, 2 on rear and 1 on each end
and if u want to get into it, if ur welder is 240v u could hook up a mini panel under the table and split it to 240 and 110 and u could run ur welder off the same table that u can ur grinder lol
anyways great shit steve, i love wood workin
