    Reed,
    the one on the pedestal is off a 10hp briggs, so its the small impeller and same as my 8hp factory keene

    those small drums are hard to find in my area and ive build aluminum pontoons for my 2 last dredges. the aluminum i use is .100 thickness, the ones on my 4" have had 5 years of hard abuse on them and are still going strong

    the 5ft x 10ft sheets i got are 67 lbs each so i can make a 6ft pontoon and still have extra left over from each one to make some more smaller sluices for future projects or a sump and pair of side sluices for this one

    the pontoons will be 2 pieces. the bottom and sides will be bent out of one piece and the top welded on after i weld up the front slant nose and rear of each . the back pontoon will have flats front and back

    ETA: dont know why the pictures turned sideways, they were right side up when i loaded them

    finished bender is 96 inches between end plates. will mainly be used on .100 aluminum for the pontoons on my 6" project and future sluice boxes . will test it this weekend
