in my opinion way to much of over kill in struts and cross members
my table cutting size is 1300 x 3100mm or 50 x 122 inch
and uses way less
if your going to use the collapsible saw horses like in (Portable Lowrider in Annapolis - #38 by wcs39204)
you don’t need the 4 long struts
if you use 2 x 140x 30 on edge in the outer edges of horses , cut out top notches for struts , bottom notches for horses they don’t need to be tight fits , mine have 3mm play
dont worry about glue just screw on angle from top make sure 2 sides touch each other . only 1 screw per strut , next strut screw opposite so it pulls back to last strut
throw on you spoil board ,
i used kwila decking as my runners, due to hardness and rigid i know it wont warp, in shed
itf you have laser with squaring lasers this makes life easy here set it up where 0.0 will be with machine kick u r saw horses till bed is square , move spoil board to be square also screw spoilboard than screw decking done ridgid as shit
