Hello
I've seen in several magazines where fibreglass is moulded into a shape to create an enclosure to use as a sub box, usually in the side well of the boot. Has anyone got a plug/mould for this work, or know anywhere that supplies them?

If you're feeling brave, you can do it yourself. I did this for my old Clio... Just use shedloads of masking tape and kitchen foil as the stuff sticks like sticky stuff to sticky stuff.

If you want more info, let me know.

 

I've seen it done on Blue Peter, with washing up liquid bottles and sticky back plastic but thought i would try the professiuonal approach of paying someone else first before getting goooed up with resin and chopped mat..

 

Found a site on the net which gave info on making home made speakers. Useful but looking for someone who cal tell me with this speaker you need this size airbox at the back to make it sound cool. Are there any resident brainboxes/physicists who can help???

Chiark: you advice on tips and pitfalls on making your own would be helpfull

 

Best thing to do is look at the speaker info - most time they recommend a specific volume and, from that, you can work out the dimensions. Don't forget to use inner dimensions, not outer, and subtract the displacement of the driver.

For fibreglass:
- mask everything off very very well
- work in a clear very well ventilated area
- BUY FROM A FIBREGLASS SPECIALIST as it will be loads cheaper
- buy many cheap brushes (B&Q - 40p), disposable latex gloves,
stirring sticks, a syringe, nick a pair of scales that you don't
mind getting covered in gunk, and many plastic pots to mix in
- Cellulose thinners are supposed to be able to wash stuff out,
but I couldn't shift the stuff adequately, hence throw away
- Take a specialists advice on the amount of catalyst to use for
the weight of resin. (I think I used 5cc / 100g - but it
depends on the catalyst used and resin used
- Wear clothes you really don't care about
- mask *everything*
- for masking, I used christmas size aluminium foil, spray mount
and masking tape.
- I found about 300-500g of resin was usable in the time before
it went off. YMMV. Start small.

Hope this helps,

Nick.

 

lol @ chiark - that looks like a cut-n-paste job

 

I too have been thinking about moulding a sub box (Spare Wheel Location)
