30-6 Posted September 8, 2017 Report Share Posted September 8, 2017 After failing to catch any mink on land after they killed some friends ducks, I'm going to try two rafts on his lake. One with a fenn mk 6 and one livecatch. I have the materials, and some questions. I will be sandwiching the polystyrene between plywood with coachbolts. If I used something like no nails type of adhesive to strengthen the build would it attack the polystyrene ? Also, to help protect the plywood would it be best to use cuprinol, varnish or both ? Cheers in advance. Quote Link to comment Share on other sites More sharing options...
Me matt Posted September 8, 2017 Report Share Posted September 8, 2017 I think youll be needing a non solvent based glue or it will eat the polystyrene. As for treating the boards- check that the preservatives your using are safe to go into a water course. Quote Link to comment Share on other sites More sharing options...
thepasty Posted September 8, 2017 Report Share Posted September 8, 2017 Find some UHU Por, its a contact adhesive but doesnt eat foam Quote Link to comment Share on other sites More sharing options...
Wilksy II Posted September 8, 2017 Report Share Posted September 8, 2017 Ever build stiks all is very good, that would do it,and as Matt said you don't want to pollute water but also put off the mink with strong smelling treatment Quote Link to comment Share on other sites More sharing options...
Fisheruk Posted September 8, 2017 Report Share Posted September 8, 2017 Wouldn't bother with preservative. When you are not using the raft pull it out onto dry land. Quote Link to comment Share on other sites More sharing options...
vampire Posted September 8, 2017 Report Share Posted September 8, 2017 Non solvent based adhesive and try cuprinol garden timber,the stuff is like liquid duck at shedding water. Quote Link to comment Share on other sites More sharing options...
30-6 Posted September 8, 2017 Author Report Share Posted September 8, 2017 I did read while researching this not to use oil based preserves but cuprinol and varnish was mentioned to use. I have various tubes of DIY stuff out the shed, I will look to see if I have a non solvent based one there, if not I will use double sided tape ( never thought of that beforehand ). I think before assembly I'll have a think and might cuprinol then varnish, especially the edges, to help slow up deterioration of the plywood while in or out of the water. Thanks for all the input.

r1steele Posted September 8, 2017 Report Share Posted September 8, 2017 Just get a pallet and put the polystyrene into the cavity with a few screws to stop it from sliding out. Quote Link to comment Share on other sites More sharing options...
R1nut Posted September 9, 2017 Report Share Posted September 9, 2017 Instead of ply couldn't you get one of those plastic chopping boards from the pound shop? No painting needed and 100% waterproof? Just a suggestion Quote Link to comment Share on other sites More sharing options...
scotslad Posted September 9, 2017 Report Share Posted September 9, 2017 Have u tried looking on the GWCT website, they developed the rafts, I looked at them years ago. If u had 4 coach bolts would u really need any adhesive? I don't think treating ply with anything will make an awful lot of difference esp when its sitting in water, it's not like it is real wood, I'd pay extra and get some marine ply. If ur on a lake I won't matter so much but if on a river its surprising how thick a rope u need to cope with floods (really a 10 or 13mm poly rope, ur normal 8mm ropes just burst) Quote Link to comment Share on other sites More sharing options...
