Re: Bill Watson's folding minnow trap
I think what it does Nobby is add weight to the tip section being less buoyant than balsa or cane somewhat.
That's why the tip has a slow recovery from being submerged. in my opinion its not the best place to add weight to a float .
Cane for me is the ideal material being strong but more buoyant than carbon and fiberglass.
Heat treating bamboo spills is a good idea mate

Re: Bill Watson's folding minnow trap
Archemides Principle is more than just about the overall capacity a a float to carry shot, and by good design can be manipulated to alter floats sensitivity. So if you add a wider section in the middle of a long thin tip, the tip will be stabilised but the down side is a reduction in sensitivity until enough shot is added to fully submerge the wider 'pip'; and at this point the float will become far more sensitive and stable. This means if one uses a heavy material for the long thin tip the more buoyant 'pip' will add the necessary stability without loss of sensitivity so long as the 'pip' is fully submerged.

Re: Bill Watson's folding minnow trap
Interesting Santiago
But wont the cork pip on a long antenna float made from a non buoyant material just prevent the float from being top heavy mate ?.
I know from some disasters I made years ago if you take the principal too far the float fail to cock because you have more weight on the float tip than the shot loading at the base.

Re: Bill Watson's folding minnow trap
Yes it will reduce it's top heavyness. But in addition, when the cork is fully submerged the tip's sensitivity is then dependent on the diameter of the tip that is still above water. Although, there will be a little added drag because of the cork. And of course, the cork 'pip' must be placed somewhere below the top of the tip.

Re: Bill Watson's folding minnow trap
Just been looking at the front cover of Bill Watsons book.
It does look like your right mate.
No mention of those float in the book unfortunately just the mention of him getting the theory wrong lol.

Re: Bill Watson's folding minnow trap
Today some 3mm clear perspex arrived and I will attempt to make one of these with a laser cutter. I will scale it up a tad, possibly double.

Are you planning a barbel trap?

Re: Bill Watson's folding minnow trap
Decided it will be 10" by 4", so not that much bigger. I have two sheets of A3 size so should be able to make two, or one if the first attempt has a design flaw. I intend to use a draw string both ends which will eliminate the need for tabs on the end triangles.

Re: Bill Watson's folding minnow trap
Here's a sneak preview. Just need to add cable ties and powercord. Made from 3 mm perspex. I made two entry pieces that will give two different angles when in position, along with five holes, so I can adjust the angle to achieve an optimum funnelling affect. Powercord will run through all pieces along the top, and be held tight by the toggles. I also included a proper hole that 20x18mm.
Any suggestions for improvements let me know please, I have one A3 sheet left so might include suggestions, if I think they'll work, on the next one.
I will post another photo when fully assembled.
