I certainly took note of that ! On reflection, I'm not sure it would be a good idea to try it as a sucker instead of a blower - it might not work properly in either mode afterwards :?.
Incidentally, you can buy those blowers ready assembled. Unfortunately, Mike Moorlach won't ship them outside the US, but I have seen them on another 'Murrican website. If only I'd bookmarked it at the time :roll: !
