Step 9: Creating the Shell Like Texture

The next step in the process was to create the correct shape on the outside of the fiberglass cone. To make my desired pattern to make it look like a shell i used car body filler. I mixed up the filler and hardener (comes as a set from Halfords). I also used a trick i had seen online which is to mix in some fiberglass resin as this makes the filler a better consistency to work with and is easier to create the shell texture i wanted. I used the card provided to apply the filler and i would suggest wearing gloves for this process as it can get quite messy. The filler took a lot longer to dry than in the test i did beforehand but i can only assume this was because it was colder and i had mixed in less hardener. Once the filler is completely dry i spent quite a long time sanding out all the bits of filler i didn't want. You can make it any shape you want and it would be fun to experiment with different shapes. By now your shell should be very strong and if it is like mine you would struggle to break it!
great! <br>
I likes zis!
hmm. this interests me greatly, as i am a man who is keen on watersports
Interesting. I suppose the easiest way of waterproofing controls is to do it the same way a watch winder works. Volume and tuner controls projecting perpendicular to the bodyshell(it really is a body shell) and sealed with a simple o ring. Then you need to make sure they cant be knocked off so recess them a bit. Good work though. GRP is fantasic stuff for small volume production!
At the moment there are strips of rubber inner tube on the inside so it is pretty much splash proof.It isn't completely water tight yet but if you have any suggestions it would be appreciated.
Simple! Place a cap on the inside around the dial. Now drill a hole in the cap, glue a rod to the dial and seal on both sides with a rubber washer. Next glue the rod extension to the dial on the radio chip inside the now water-proof container.
Um from the pictures this is in a garage not a university, and I could have done this in 12 hours. <br>Otherwise great job making a weird looking radio.
You can make it in 12 hours? Do it then, i bet you don't.
Interesting concept, I like it!<br />How do you seal against water ingress at the dial locations?<br />
I'm glad you asked as I was wondering the very same thing.
