final job was to number the inner and outer dials and install
the 15 minute markers. The inner dial was to be numbered using
Arabic numbers sandblasted and painted into the grey pavers.
The outer dial was to be numbered using Roman numerals
sandblasted and painted into large rocks. The rocks were
collected from the banks of the Winnipeg River along the
Ironwood Trail in town. Harry Noel
and I did this job and a local contractor, Lloyd
Rattai, helped move the rocks to the site and later on
to the dial plate.
Access to a
sandblaster was available for sandblasting at the site. Rubber
masks of the numbers were prepared at a business that made
memorials. Fred Bilsky applied
these to the pavers and rocks and I did the sandblasting using
sand left over from preparing the gnomon.
The 15 minute
markers for both dials are positioned in the grey pavers.
These are made from 0.5 inch brass round bar stock. Jeff
Harding machined these markers and I installed them. 92
markers were installed by first drilling the pavers and then
setting them in using a silicon rubber compound.
numbers for the inner dial are visible here. The rubber from
the rocks has not yet been removed. The masks are not very
large due to the cost. To provide additional protection an
inner tube was used to provide additional coverage when
hole was dug by hand for each of the rocks. A mixture of
limestone and cement was used to backfill the hole. When it
rained the cement got wet and then set.
