  • I've got the tools to make a former out of wood pretty easily, my thinking was that I could then make a mould from plaster of paris.

    Release agent into the mould, twill and resin, then use the former to press it into shape whilst the resin goes off.

    Sound about right?

    If it worked the resulting guards should be very light, very stiff and - crucially- very thin.

    I guess you could potentially make it a lot thinner under the fork crown. Which I'm guessing is the main place it needs to be thin.

    If you have some sort of support/mount on both sides of the brake caliper then I'd guess it would need next to no strength in that section... But that would be for a rim brake.

    How would you* fix it to the underside of the fork crown on a carbon disc fork?

    *or did you on the TM?

    Yes, although I wouldn't use the former or buck to hold it in place. Use some release film and peel ply, and then vac bag it. Oh, and don't use plaster of paris for the mould. Once you've made the buck, and polished it to a shiny polish, make the buck out of CSM glassfibre and polyester resin. For example, making my carbon fibre car seat
