[QUOTE="gcause, post: 89243, member: 1497"] Yes I was thinking of a plain screen with metal reinforcing around the top with a slick plate at the bottom third of it. Like the Thompson unit uses. I was also thinking of the wiper washer motor but it's a 12volt system and I think the petrol one would last all day as you are not stressing it at 90 strokes a minute. The one my brother has is a variable speed so I could do some fine tuning. I would add a handle to the flywheel so I could run it without the motor if necessary. i.e. I run out of fuel or don't want to have the noise of the engine going. The wheelbarrow concept is appealing to move it about but I would have to work on a folding mechanism for the wheels and handles to make it easy to transport once packed up. Stability was also my concern with that I note yours has a metal frame to overcome that issue. Cheers, Grant [/QUOTE]
