Thought I would let you guys know about my latest project I'm putting speed holes in my bonnet
.
These are some of the materials I've used so far, fibre glass resin, fibre glass matting, hardener to set the resin, scissors and heaps of small paint brushes.
This is the sort of shape I was after but more flush looking.
First off I made a mould of the shape I wanted using thin sheet metal.
Once the mould was made I used aluminium foil as a base sheet which I covered in vaseline to stop the resin from sticking I also did the same to the mould.
What you would normally do is put one layer of fibre glass matting and cover that in resin waiting for it to harden before putting the next layer, but because I'm impatient I put on three layers and waited for that to dry. You should do it one layer at a time and wait in between to prevent air bubbles forming and wrecking the finished product. I added 6 layers in total so I only had to do it twice.
I've also added extra fibre glass around the sides which will be attached to the bonnet from the underneath, because I knew that these areas will be the ones needing the most support.
At the moment I'm up to the stage of modifying the bonnet, I've cut out the area where the vent will be added and have cleaned the surrounding area in preparation. I have also shaped the outer edge of the mould to fit in the hole I've cut.
The next step will be fibre glassing the vent to the bonnet from the underside and then be using a little bit of bog to fill and smooth all the areas to make a flush and clean area for the final step of painting.
NEXT STEP
i cut out the 2nd hole
i grinded some paint away near the 2 holes (so the resin sticks better)
i shaped the 2nd vent
taped up the vents
1 because the tape holds it there
2 becasue the tape stops the resin from coming on the top side. (so it should be smooth when i take the tape off)
here you can see the tape and all i do is run fiberglass matt over the tape to join the vent to the hood.
and it glassed
and the big hole that has to be filled.
this is the hole filled
