Hello, I am very interested in exploring how I might make something like this aluminum rack for my Suzuki Vstrom in CF
https://ravetechmotorcycles.com/store/en/suzuki-dl650-v-strom/32-dl1000-dl650-2018-aluminium-top-plate-.html

Would the Pre preg materials be the most easy to work with and cost effective? I have a household oven at my shop I use for powder coating. It seems to fluctuate a bit when turned on,  but maybe it would be stable at 120C. Could I use a plywood mould to form it on? I'd like the rack to be about 3/16" in thickness. Seems to me the CF would be quite expensive to build up that thick. Are there other materials you use to build up thickness? I do not have a vacuum pump but do have a large compressor. Would it make more sense to buy a vacuum generator for the odd one off project? 
Suggestions greatly appreciated.
