Step 8: Beam Assembly - Inner Beam
A:
Interlock the cut-outs on two (488) Inner Beams then attach with four 5/16 x 1-1/2” Hex Bolts (with 5/16” lock
washer,
5/16” flat washer and 5/16” t-nut). (fig. 8.1 and 8.2)
B:
Place one (026) Splice on top of (488) Inner Beams with long side facing down, 52” from the end of one beam
then using a 1/8” drill bit pre-drill a hole using the countersunk holes as a guide and attach with two 5/16 x 3” Lag
Screws (with
5/16” flat washer) and four #8 x 3” Wood Screws. Turn (488) Inner Beams over and repeat for other
side. (fig. 8.1 and 8.3
)
C:
Repeat Steps A and B to create a second Inner Beam Assembly.
