As a general rule, all the measurements I have listed here will be more accurate if you mark the centre of each tube and then measure the "holes" from the centre out as opposed to from the ends in, in case some tubes are not cut to the exact lengths.
Key - (V) = Vertical. (E,W) = East,West. (N,S) = North South. 13/16" brill bit used for 3/4" bolts.
- [4] 92"×4"×4" Tubes for base.
- [2] outer base tubes - 13/16" (V)holes 2" from ends. 1 (V)hole 4" front of centre. 4 (E,W)holes for wheel plates 9" & 13" from ends. 2 (V)holes for hydraulic base plate 13-1/4" & 22-3/4" behind centre, 1-1/4" from outer edge.
- [2] inner base tubes - (V)holes 2" form ends. (V)hole 4" front of centre. (E,W)holes 6", 9" & 13" from ends & 1 (E,W)hole in centre. 2 (V)holes for hydraulic base plate 13-1/4" & 22-3/4" behind centre, 1-1/4" from inner edge.
