each j-bolt so the angled portion is pointing outward and tighten the lower
nuts to secure the assembly.
3. Construct a concrete form shown in FIGURE 2-3 out of 2 in x 4 in lumber
24 in square (inside dimensions). Construct the 1 in x 2 in template frame
and set it aside. Center the form over the hole and drive a stake centered
along the outside edge of each side. Level the form by driving nails
through the stakes and into the form while holding the form level.
4.
Position the j-bolt template as shown in FIGURE 2-3. The top of each bolt
will be 3.00 in ±0.25 in above the level of the form. Level the tops of the
j-bolts in all directions using a small level and secure the j-bolt template to
the template frame with 7/8 in screws where holes in the template overlap
the wooden frame.
5. Fill the hole and form with concrete. Screed the concrete level with the
top of the form as shown in FIGURE 2-3. Smooth the concrete around the
three j-bolts and allow the concrete to harden.
