afforadable source of dredge float material

Postby obdiah » Sat Jun 17, 2017 12:52 pm

after building several dredges one problem allways arises , what to use for floats and theres lots of opinions but nothing is ideal other than commerical floats
the best I had found so faf and used on my last few dredges were water softener tanks the ones on my current 3 in are 10 in dia and 48 in long they work but floation is barely adaquate but it works and they are rated 120 psi pressure so I use them as air storage resevours and there durable made with a polly liner and wraped with stranded fiber glass if they were just a foot longer
but then i found this stuff 10 in dia pvc air ducting .187 thick wall and 10 ft for $73.99 enough for two floats

might need a plywood ring bulkhead were the mount to the frame or maybe not end caps are high at 20.00 each but might get by with something home made for that what yall think? https://www.qcsupply.com/pvc-50-lb-duct ... gQodrcQAgA
thier nears store to me is in clinton nc between wilington and fayetville

Ive been using 15 gallon drums. They can be found easily on craigslist for like $10 a piece, they are very durable and its easy to make a dredge frame to accommodate them. 4 of them would be more then enough floatation for a 4". If any of my store bought floats get holes I will not buy the over priced keene or proline floats I just plan on building a new frame and using the 15 gallon barrels. Just my 2 cents.

15 gal drums work great i have used them before and there free ( I have a friend that is a dairy farmer and they get them all the time but as I am getting older the weight of the support structure adds up and I went to a frame less design and all aluminium and let the floats carry the load of the components cuts down on handling difficulties this is the way I build them all now

I cant tell from the picture but is that a store bought jet flare or homemade? If its homemade what did you use. I can build power jets and sluices but the one thing I haven't been able to figure out how to easily build is jet flare.

Thanks

Easiest way is to cut some pipe right down the middle and weld a piece of sheet metal on each side in the shape of a V.

I have seen some people use a traffic cone for a flare, cut a piece of wood or sheet metal to attach to the big end to form the cone to an oval.
