After looking at back pack sluice, I wasnt really that keen on the design of the top edge of the mat, making a lip, sitting to high above the flare.
On this particular sluice, it also had a small gap between the flare and the base.
Soooo, if your unit is similar....
It is possible to make a hem without having the spaghetti.
Using a straight edge and sharp knife, score down through the spag ##mm (25mm?) in from the top edge.
Carefully skin off the spaghetti to this point, clamp a peice steel angle line over the the other edge as a guide.
After removing what you can with a blade. Cover the rest of the mat with a peice of ply and clamp down to protect it.
Using lpg/butane or map gas, do QUICK passes of the dags.of the hem lip area.
Whilst still hot, use a paint scrapper to help compress/ flatten the dags.
Cool off with water .
Loosening off the 2 wing nuts on the flare, you should now be able to slide the hem under the flare.
This gives the material a lot better approach to you riffles.
Leave the redundant clamp/ riffle as is, or remove

Cheers, it made me wonder how much gold would of crept under the mat before.
A nice smooth transition from flare to mat now, without a lip.
Everything can be improved on.
