okae. speaking from past experiences. Be careful with that amount of hardener. you can get serious burns (i accidentally got some on my arm while it was exotherming) spread it out in a tray to slow down the process
yeah, just sand it down with around 600 grit to get it smooth, the final coat will go on and hopefully dry as smooth as glass, so you won't have to sand a much before paint. When you do your final coat, don't use any of the kitty-hair matting, otherwise you'll never get a smooth shape, i think one layer of mat is more than enough for what your doing. It's not like the case is gonna be subjected to any major trauma. TBH, you really don't need a polyester topcoat, if your patient you can sand the fiberglass all the way up to 1500 grit and just take it to paint like that. That's how i've always done it. basic steps: fiberglass>sand>fiberglass>sand>light fiberglassing>final heavy sanding>finishing paste>sanding>paint takes a long time, but it's not too bad. Also, for future reference, fleece works awesome for fiberglass. You can stretch it tight over your form and goto town on it, since it soaks up so much glass. Just a tip for anyone reading out there. here's a pic of a box i made for 4 10" subs(really low airspace for punchy bass). I used the fleecing method to make this. If anyone has any questions regarding this, feel free to PM me. Lee
the difference a day... or four... makes glad it worked itself out! GL with the rest of the fiberglassing!
Looks like the show will go on... Suddenly the 'simple fiberglass shell' isn't looking so simple though, maybe a title change is in order. I'm really excited to see this finished.
So why can't you just use thin acrylic sheets and glue them at the corners? Acrylic glue is crystal clear and if you do the joint right you can hardly tell you glued it anyway.
It looks good...I definitely like that design. I still don't think it would be completely impossible to glue the acrylic together, it would just be a matter of getting the correct curves. However you do it, it will look sick. Keep going!
Kayin-in-Black would be the person to talk to here about resin casting, but he's busy with other stuff lately. I do know you will have trouble getting the air bubbles out of a complex cast without a vacuum chamber. The fumes are pretty flammable too, so you could be forced to wait for Spring. -I DO want to see you cast this, though. Sketchup: What you want to do is use the intersect command to cookie-cut out the pattern.
You called? Pour it and heat it with a hair dryer afterwards and the bubbles will float to the top. Any other questions? I'm still here, just busy with a lot of stuff ATM, one of which will be showing up here soon.
