I have it in my build thread but I figured I would create a dedicated thread to show the way I did it.
I hear lots of people say they want it but because you can’t easily get the inner bracing/mounting brackets they won’t do it.
I decided to go composite with my brackets. I used a combination of carbon fibre and fibreglass. I only use epoxy as polyester resin is s*** and it stinks way too much.
Epoxy is way stronger than polyester also. You can use polyester only if the fabrication is one piece done at the same time. In other words once polyester is cured and you attach more polyester to it by adding more cloth and resin then that joint is very poor. Epoxy on the other hand is far superior in this way.
It’s a pretty straight forward process actually. Some pics are self explanatory and the ones that aren’t I will give details.
The pic below shows the pieces after I cut my fabricated fibreglass board to shape.
The board is made up of epoxy and 10 layers of cloth. It gets laid up on a heavily waxed and buffed piece of sheet metal . The wax allows easy separation of the board after curing.
The pic above shows the 8 layers of carbon and epoxy laid up on the quarters where the carrier mounts. In this process I put down aluminum tape for protection then waxed. After curing it was laid on the carrier mounts and trimmed to pretty much the same dimensions.
The cut out pieces that will be bonded to the carbon using thick 5 minute epoxy shaped to a fillet so it’s a smooth radius corner. This ensures the next layers of fibreglass bonds completely without any air pockets. If there is no radius this would not be possible. 6 layers of cloth and epoxy on the inside are used to bond all 3 pieces together. It goes on the inside because if you put it on the outside the shape my not conform to the quarter Then 2 layers on the outsid.
