Have you thought about taking up a hobby such as Genealogy for example Herman?
BTW. I'm quite happy with my Gardiner's swivel. What I would like to see is one that could be locked at 90 degrees so it becomes fixed.
Unger has a swivel squeegee that does this but it doesn't work properly on either of the squeegees we have.
Maybe you could focus on this. I'm sure it will become a major hit and all the manufacturers will be fighting over your patented swivel.
But it mustn't look like the contraption Wagga is proudly promoting. We don't need a sky scraper that sticks up above the top of the brush stock or that extends from the top of the pole by a meter.
