Figure 4: snub ends
1) Cut beams to length, with snub ends, as shown in figure 4.
2) Tack weld two long beams and two short beams together to form a 1420 x 1110 mm
rectangle. Ensure the rectangle is flat and square (for flatness use flat surface or eye; for
squareness equal diagonals) then fully weld. Repeat this with the bottom beams.
3) Cut four legs to size, clamp and weld a leg to each corner of the top rectangle ensuring
each is set square to, and flush with, the top edge of the angle iron (see figure 5).

4) Clamp the lower rectangle in position and weld to the legs.
5) Cut the strap, ribs, cross ties, tray supports, pads and feet to size, drill the pad holes and
weld them to the long top beams in the positions shown in engineering drawing TD 001.
