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" drill bit used for 3/4" bolts.

  • [4] 92"×4"×4" Tubes for base.
    • [2] Outer base tubes - 13/16" (V)holes 2" from ends. (V)holes 4" front of centres. (E,W)holes for wheel plates 9" & 13" from ends. (V)holes for hydraulic base plate 13-1/4" & 22-3/4" behind centres, 1-1/4" from outer edges.
    • [2] Inner base tubes - (V)holes 2" form ends. (V)hole 4" front of centres. (E,W)holes 6", 9" & 13" from ends & (E,W)holes in centres. (V)holes for hydraulic base plate 13-1/4" & 22-3/4" behind centres, 1-1/4" from inner edges.
  • [3] 60" Under base tubes.
    • (V)holes 2" & 10" from ends.
    • (N,S)holes 14" form ends.
  • [2] 55" Front vertical tubes.
    • (E,W)holes 2" form tops & 2", 6" & 9" from bottoms.
    • (N,S)holes 6" from tops & 5" from bottoms.
  • [2] 52" Centre vertical tubes.
    • (E,W)holes 2" from tops & 6" from bottoms.
    • (N,S)holes 6" from tops & 2" from bottoms.
  • [2] 59" Rear vertical tubes.
    • (E,W)holes 6" from tops & 2", 6" & 9" from bottoms.
    • (N,S)holes 2" from tops & 5" from bottoms.
  • [3] 44" Top (overhead E,W) tubes.
    • (V)holes 2" from ends.
    • (N,S)holes 6" from ends.
  • [2] 84" Top (overhead N,S) tubes.
    • (E,W)holes 2" from ends & in centres.
    • (v)holes 6" from ends & 4" from of centres.
