KiKaZz74 Posted December 8, 2015 Report Posted December 8, 2015 You will most likely have to do finish work. It's gonna be basically impossible to get a smooth outter layer without a nice mould. Body filler and sand paper will be your friend and enemy. The other thing I've used thanks to a friend for tweeter pods is a wooden sphere to like top railings or something like that. Forstener bit it. Drill an intersecting hole and lamp post thread it so you can run wire thru it.

Clownrock95 Posted December 8, 2015 Report Posted December 8, 2015 get a Styrofoam ball from a crafts store and cover with as many layers of fiberglass needed. let cure then cut/drill a hole the size of the driver needed. use acetone to dissolve the Styrofoam ball. your left with a spherical "pod" X2
Davethebuilder Posted December 9, 2015 Author Report Posted December 9, 2015 Looking like I will have to settle for a 'near' uniform exterior... Which is ok, but I'm wondering if anyone here has any information on the "rolling ball method" for making macrosphere balls and if it could be scaled up to make larger balls... I cannot find any information with a web search as well as any videos showing the process how they are made... Thanks for your help
never knows best Posted December 9, 2015 Report Posted December 9, 2015 not sure if these are the size your looking for. concrete shpere molds go down to 8" dia. if you do go that route you will need some mold release... https://www.google.com/search?q=concrete+sphere+mold&biw=971&bih=991&tbm=shop&source=lnms&sa=X&ved=0ahUKEwju5JKX1M7JAhVDLyYKHe7xC8sQ_AUIBigB&dpr=1

boom50cal Posted December 10, 2015 Report Posted December 10, 2015 how important is it, that the spheres must be made out of fiberglass? Bet you could get some ABS plastic spheres made with a 3d printer a lot easier On 1/4/2013 at 9:31 PM, HatersGonnaHate said: Wow. 184 posts and I think you're a fucking asshole.
Davethebuilder Posted December 10, 2015 Author Report Posted December 10, 2015 Settled on the idea of using a polystyrene ball and adding fibreglass and not worried about leaving it in the sphere... Main thing is that the (semi)hollow sphere is made of fibreglass or even Kevlar... Aiming for the strongest and hopefully can be produced with reasonably good speed. The idea of the 'rolling ball method' for making macrospheres sounds appealing only if it can be done in larger sizes... Still can't find out how it's produced though.
yurvalentine Posted December 10, 2015 Report Posted December 10, 2015 How strong are we talking? Because if you're wanting aramid strong I'll tell you know they will be expensive as hell and very time consuming to make. At that point I would recommend having a mold machined.
