Got all parts ready needed to assemble table. I purchased some heavy duty machine legs that needed to be modified. The holes I drilled larger to except a 5/16 carriage bolt so can attach to the 1545 extrusion and a 9/16 hole in the 1545 extrusion to allow for leveling. The 3" base on feet have two holes so can be easily mounted to a future table.
I tapped the six 1530 cross pieces ends to bolt to 1545 rail. I used a drill with the clutch on a medium setting, seen this on a utube vid and worked great.
Than I drilled the 3/8 through holes in the rail than 9/16 in slot for bolt head. I seen a jig for this on ebay for $75.00 so I made my own.
