So I was inspired by George's float project the other day.
My dogs have this toy which is basically a big 12" egg made of little over 1/4" thick injection molded plastic.
Let me back up a bit. I have a foam filled lifeguard can and rob Allen hard float. I like them both and use them regularly for various dives. I have always felt that they are both too buoyant though for using to hunt soft fleshed fish without a bungee. I don't like bungee because they break and have to replaced.
I have wanted a smaller float or series of floats to have gradual pressure.
So I made these. I used the egg, us composites 4lb two part expanding foam, climbing nylon tubing rated to 4000 lbs tensile strength, and two beefy tuna clips from neptonics.
Each has 433cu in of volume compared to the RA float w 671cu in.
The first one came out a little off because I wanted the ends a little longer to encourage them to wobble if they are pulled under yet be able to stay out the water as much as possible while being towed
Always mix foam in small batches.
Taped the ends and poured half the foam while spreading out the webbing inside. My thinking is that the foam is now inside of the loop so if a significant vector of force is exerted it would have to pull the interior foam out through the hole to fail.
The eggs are strong to begin with but after foam filling and letting it cute I can now stand on it with no flex
I am pretty pleased with the final product
