I need to make a couple of horns ( for audio use ) and have a couple of questions as I never worked with this stuff before...
The local Home Depot clone ( in scandinavia ) sells the glass fibres, polyester resin, hardener and gelcoat wich should be everything I need ?
The mold is made from a big chunk of MDF ( Medium Density Fibreboard ) that I laminated from several smaller sheets, then cut the horn flare contour in it on a lathe..
To give you an idea of what I am trying to do I put a picture of an existing horn here:
Can anyone give me some idiot proof instructions on where to go from here, before I waste 100$ worth of fibreglassing ingredients?
If not, heres a few questions:
How do I get the surface thats touching the mold as smooth as possible? ( The mold was turned on a lathe, so it is smooth, but I'd prefer the fancy shiny surface :-)
How do I keep the fibreglass from sticking to the mold?
Any tips that may come in handy?
I know that this process involves nasty chemicals and nasty dust, so I will be doing this outside wearing some sort of dust filtering mask..
Thanks in advance
