Floating shark tooth sifter

16 posts in this topic

Didn't get out to the cliffs this weekend, so I decided to make a floating sifter. This one has 1/4 screen in it. I am going to make another one that has 1/8 screen, but I'll have a smaller 1/4 screen that fits over it along with a scoop that I can pour water over the larger screen. I think I will fashion some sort of strap on it so I can carry it on my back so that I can still surface collect until I get to a good sifting spot.

No, it's 1/4 galvanized hardware cloth.

Great, looked like plastic. Didn't think plastic screen would hold up to well! Again awesome job.

Here is the scoop. I plan on attaching it to the 1/8 screen float, but also putting a piece of foam on the back of it. I figured that it can just float beside the sifter until I need it.

Nice design! 

How do you attach the hardware cloth to the PVC?

Regards,

The design and making one of these is pretty simple. The drawback, that I have seen with sifters made with pvc ( especially schedule 40 like this one) is they will not hold up under heavy and demanding usage. When you are in a river environment shoveling 5 and 6 shovel fulls into the screen all day the pvc does not hold up as well. That is the reason I use wood, they may be heavy, but if constructed right and taken care of they will last forever. And by adding pool noodles, just as shown, the wood floats too.

Your typical white schedule 40 PVC pipe will become brittle and break after prolonged exposure to sunlight. It's meant to be buried inside the walls of your home.  In fact many plastics degrade over time with exposure to UV light (=direct sunlight).  But I would think if you stored it between trips out of the direct light it should last a fairly long time and considering how cheap it is you could just keep building new ones.  But maybe just don't leave it in the back of the truck when not in use.

 

I also like my classic wood version.

Nice design. Take some photos of it out in the field next time so we can see it in action. The other useful feature of a sifting screen meant to be used in water would be an appropriate length of cordage made into a loop and tied off on a corner of the sifter to act as a lanyard. These are useful when solo sifting in rivers so you can tether the sifter to you leaving your hands free for shoveling.

 

Cheers.

WAHAMA90, Loved your light screen. So much so that I "stole" your design and made one for my upcoming Florida trip. I was hedging between 1/4 and 1/2 screen, then I thought, why not try a new version of yours where I can have the best of both worlds. Will post a pic in a few days to see if those who sift think it will work. Again, your design seems great for us Northerners that have to pack it in our suitcase. I left the handles unglued so I could detach and slip it into the suitcase easier.

Also I attached my screen using zip strips every 1.5 to 2 inches. Seems solid. We will see

Maybe some paint on the PVC would protect it from sunlight?

Really cool!

 you would have to prepare the pvc to hold the paint, otherwise it will peel off. If I were to make one of pvc, I personally would use schedule 80 cpvc
