[QUOTE="Tommtb7, post: 14778, member: 638"] I heat the sheet with a heat gun, the sheet is from bunnings it was $45 and the heat gun I already had but bunnings have them for $30 (I'm a fan of bunnings) then I got a road sign from a recycling emporium which I think is a fancy name for a junk yard. I scored the aluminium road sign with a grinder along the fold marks then just bent it to form a channel with 90 degree bends I made the bends on angles down the entire length to get a flare to drop the water pressure to suit the drop riffle design so if you were looking at it from birds eye view it would look \^/ the arrow shows water direction [/QUOTE]
