If he builds it with aluminum and uses the correct
grade, should be no problem.

Since his tower tapers, he could use larger
wheels at the top of the device to keep him
plumb at the higher levels.

Have you looked into renting a bucket lift,
not too expensive for one time and a lot safer !


Maybe he doesn't quite know what to look for.
Many years ago an article was published here how to make this Hazer type
device..It looked heavy on the side of his tower.
If anyone wants the article, I could try to find it and make a scan.
Eskay.
