[QUOTE="Savant, post: 120716, member: 546108"] Some of the stuff I've read suggests you let each layer harden before the next layer.. so you should be able to piece it together over time.. Other info I have read said go ahead and build it all up at once... *shrug* I immagine that as long as you scuff the surface for each layer that the resin should bond fine to the previous layers.. If you can do 2 or 3 at a sitting, that would probably help too.. Porting I'd immagine is just like normal.. and you can probably just resin/glass the tube in place once you are done (from the inside).. You will have to fill it with water to get the volume though.. At least, I've not heard any other ways to determine vol in odd shaped boxes (you can guesstimate by making it into rectangles/triangles.. might get kind of close).. Once you get the volume, if it's too much you can add stuff to the box.. in side.. like 2x4 pieces, etc.. someone even mentioned a foam ball for crafts (stiff foam balls/blocks/etc).. they also said that the air space in those would be problematic for specific volume calculations, but I was thinking that if you coat the outside with a layer or 2 of glass/resin that the interal air volume of the foam piece would no longer be an issue (you have a solid object in the box now).. Just make sure you secure it well [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] I'm not sure about having to run to 5/8" though.. seems a bit thick for fiberglass.. Part of the idea of using glass is that it's stronger than wood.. Although, if you go thin, you will need to have bracing in a few places to prevent flexing... Hope that helps ... [/QUOTE]
