Hi NL,
Nicely done!
IMHO, as long as you have personal health insurance and life insurance; the related safety issues are almost always a personal choice, and again IMHO the more appropriate realm for that discussion is between you and your own SWMBO.
We have been thinking about making something similar for tree trimming, etc; but we will probably incorporate our bucket forks as part of the under floor support for it.
I would also be making a dedicated place for my small HF gennie and electric pole saw so that I can reach higher branches than the bucket lift would otherwise allow.
The other advantage of using the pole saw is that the business end is far enough away to make any kind of complications involving skin/moving chain contact kind of hard to imagine- so much so that I think it would have to be a deliberate choice.
Are you planning to add any safety railings or an attachment for a safety line/harness?
Thank for sharing (and thereby opening your self to criticism by the more safety-conscious members) (NOT to say safety nazis).
Thomas
