Not being friendly with heights is a problem. In my former life I had to climb ladders and was always apprehensive. To this day I do not know how I screwed up the courage to do some of the things I did off a ladder.
I had several jobs that required climbing, hanging out a window multiple stories in the air, and standing on top of a ladder balancing myself by grasping a window sill but none scared me as much as these two.
It was in the early '70's when I was called by an insurance company to replace a plate glass window on the second floor of a department store. The window install went from the outside and that presented a unique set of problems.
We debated scaffolding but it would not provide a wide enough platform to lift the glass to the second floor level.
I knew a guy who erected steel buildings and he had a truck with a scissors mounted bed that elevated the body and rented his truck for the day. We had to make a platform larger than the existing bed of the truck to accommodate the piece of glass and provide enough room for a man on each end to lift the glass into place.
Good thing OSHA wasn't watching because now I recall there were no safety rails. It was a wide open platform with three men and a large piece of glass working about twelve feet off the ground. PLUS, required the use of a four foot step ladder to remove and replace the top metal facia that held the glass in place.
This was labor intensive as it required six men to do the job. Three on the ground and three on the truck platform. The glass size was roughly eight feet wide by six feet high, 1/4 inch plate glass and weighed approx. 150 pounds. There was a man on each end and one in the middle lifting with a suction cup.
Got the truck on the sidewalk, and first order of business was to remove the broken glass. That wasn't too bad as we got a small section cleared could pass smaller pieces through to the inside. Once the opening was cleared and everything checked to replace the glass, we carried the sheet of glass up and onto the truck platform using staging.
Slowly elevated the platform and the thing was wobbly because of the height and scissoring losing stability the higher it got. This had all the ear marks of, "... a thousand things could go wrong," scenario.
We got the replacement glass in and after cleaning up and getting paperwork signed, went for a cold beer, or two. Maybe three .....
The other job that scared me almost as much involved climbing and hanging on top of a ladder while juggling a piece of plate glass four feet wide and ten feet high!! It was in 1980, and my head was so into how we were going to handle the replacement, on the way to the job I was stopped for speeding. Luckily, I got off with a warning.
At least that replacement was only a foot off the ground but the kicker was, just as we cleared the opening of the broken glass, the wind came up. This created a different problem because the glass was so high and very narrow in width. It bent like a twig but luckily, we managed to get it in the opening without issue but I can tell you I was one concerned and scared pup as the install required me to be on top of ten foot ladder to trim the glass to fit the opening.
If there is any saving grace it was shortly after the install of the long thin plate glass, I hired an experienced glazier and my climbing days in the business world ended!!
(sigh) The things we do when we are young and trying to make our way in the world.
