Appendix A. UTBASE paper
template
If the metal template shown in
(p. 11) for installing the UTBASE was not
included in the purchase of the tower, a wooden template for installing the UTBASE can be built
using a paper pattern. The pattern is centered on a 45 x 60 cm (18 x 24 in) piece of 1.27 cm (0.5
in) plywood, then three holes are drilled for the three anchor bolts.
1. Print out all three pages of the paper pattern. Print the pattern at 100%. Do not scale the
printer output. Each page contains a 3-inch ruler used to verify the printed page is properly
scaled. The printed ruler must match up with an actual ruler for the scale to be correct.
2. Place the three pages on a level surface and position them together as shown on each
page. Page one will have a portrait orientation while pages two and three will have a
landscape orientation. Line up the lettered boxes and make sure the printed borders of
each page line up where two pages overlap.
3. Secure the three pages together with tape.
4. Verify hole placement on the template is correct by confirming the distances printed on the
pattern match the actual distance between holes. Adjust the pattern pieces as needed to
get the correct dimension.
5. Center the pattern on the plywood. The bottom edge of the pattern must be parallel with
the long edge of the plywood. Secure the pattern to the plywood.
6. Drill a small pilot hole through each anchor bolt hole on the pattern.
7. Use a 19 mm (0.75 in) drill bit to drill a hole for each anchor bolt.
8. Attach the wooden template to the template frame in place of the metal template as
shown in step 4 in
(p. 11) and continue the UTBASE assembly
instructions from that point.
