OK I know there is stuff all over this forum on Water channeling got sick of searching so lets beat a dead horse Looking for what every one is using for materials to make there water channeling lets get them all in one spot so dopes like me dont have to go searching [] I used Touch n Foam Black (this is an polyurethane sealant) in the Boston looking for something a little better maybe thanks Monk
um thinking of useing this http://www.owencarpet.com/rubber_carpet_pad.htm in my next ship for Water channeling or something like it
that carpet pad stuff is like a wetsuit.drop it in the bottom and cut as you go then resin 2-3 times. its light too
For my water channelling I use foam blocks. I had a open hull (i.e. non-fiberglass) I would cut blocks and slide between ribs Very snug. then take a belt sander and sand down the hull. The blocks would take out space up to the 1" below W/L mark across the whole hull. then I used the West System and harden the hull. Then using a sander, knife, dremel, drill, grinder or what ever would work I carved out the inside to my specs. Then used the West to seal it all up. If I remember right you got one of those fiberglass hulls. You could use the foam block and build a "plug" so to speak. and insert it in the bottom using west to firmly attach it then carve to your specs and west again. That would take a little time sanding the plug and trying to make it fit tight. Air pockets could/may become exposed and could fill with water thus defeating the purpose. Maybe spay foam and then carve and west. But you still run the risk of air pockets with that. Balsa wood is a great bet. I use to get these balsa block bag which had about a 1/6 of a cubic foot of various blocks. But then you got to shape each block to fit. I've never did a fiberglass hull so I would be speculating but my first attempt would be with the spray foam. For several reasons. 1. I have control on where it's going 2. hull conforming 3. It aint too bad cutting out 4. Mistakes can be easy to correct (but not all) 5. If I screw the whole damn thing up it will come out it in a reasonable amount of time and effort . The down side 1. can be a major mess 2. Have to wait for the stuff to cure 3. can't put on too thick or the stuff won't cure. The final choice is up to you. See what others have to say before you go thru and put on in. Also keep in mind that you need to make room for everything so preplanning where stuff goes is vital and making allowances. My channelling incorporated a spot for my co2 tank to sit center of the hull. Lots to think about when doing this. Good luck Danny
None of us have had weight issues using the concrete sealer, they must of put it in to thick. I have it in both my PE, and Kumano.
I used concrete sealer.... and I put too much on. It took like 2 weeks to dry. But it is dry completely now. Good to go!
You have to be careful when buying the concrete patch stuff. There are quite a few different types, and some are heavier than others. Make sure you get the self-leveling type, and put it in thin. Perhaps 1/8" to 3/16" thick. That way it dries in a reasonable amount of time. You can probably pour it in seperate layers if you need it to be thick. David R. posted a photo of the type we use here in Ohio. It seemed really light to me. Mikey
Yea I used the wrong type in PE. It was like a concrete paste,not very fluid at all. Difficult to level out too. It took many days to dry. It did work in providing excellent stability and for water channelling. Does anybody have any pix of brands to post here of the correct types?
I think the photo was posted by David R. Either his P.E. build, or perhaps in Mike's Bearn build area. Mikey
The photo is in David's "My new project V.U. thread. Page 2. last photo. In the warship builds area (I think). Mikey
