Table Sagging-Realy need input
Hi I'm really new to diy and woodworking in general as im only 20 and im having problems with my table sagging on the ends as i havent gotten around to doing the legs and it is sitting on saw horses. It is a 3/4" thick piece of plywood with 3/4" thick red oak wood flooring on top to get it look like a basketball court. it is 4' by 8'. like i said the two ends are sagging and i was wondering how to fix that. I was thinking that maybe if i put the legs on and a table skirt it would fix it but then i was thinking maybe that would just secure it in the place it is now, sagged, or that it would start to sag in the middle if i just went with putting the legs on. I really would like some help as it is a really nice table i would post pics but do not know how to..... any suggestions to get rid of the sag. was also thinking of putting on flat surface and putting weight on top dunno if that would do it.
thanks in advance
