RE: Foam Hulls
hey guys,
i thought id throw another way of glassing,,out there, i made a tug hull with this format and it worked well and gave me a very strong hull with very smooth surfaces....and the hull exterior is not affected by water or most chemicals
supplies: hull plug, aluminum foil, superglue (fast set),2+ rolls of self adhesive white or yellow drywall repair tape, 1 or more packages of the large tubes of JB WELD "5 ounce size", some type of stiff yet flexible spreaders/squeeges, scissors, epoxy or resin compound, fiberglass mat or cloth
1 form your hull to desired deck dimensions
2 cover with aluminum foil
3 apply self adhesive drywall repair tape to foil surface. applying more than one layer of tape over itself in different directions gives a very strong weave. someitmes the tape doesnt want to stick to itsel so a little super glue in those spots will remedy this "lifting"
4 mix JB WELD (one package to start coverage will very by size of model and thickness of application)
5 apply JB WELD over tape and press into tape (this stuff is very sandable so dont worry about sags or drips at edges)
6 this outer shell, the JB WELD should be formed using more JB WELD or putty/filler before removing plug, at this point the hull is flexy
7 when satisfied with hull exterior remove plug completely and all aluminum foil,it should peel out relativly easy, i pin my sheets of foam so they can be more easily seperated. if you glue them together you will have to break the foam out. note see step 10
8 with plug removed mix epoxy/resin compound and using "yellow tape" apply first run of epoxy to the keel and bow/transom areas
9 using fiberglass cloth/mat glass entire hull interior cross bracing can be added at this point as well as deck cleats
10 trim hull edge (bulwark) to desired depth using dremel,,you can trim hull edge before removing plug
