Hi all.. sorry if this makes no sense but I'm clueless.
I have a completely knackered elbow and need to immobilise it and then protect it from the rigours of mountain biking.
Have kind of worked out making the mould but laying the carbon fibre (or similar) is way out of my scope.
It needs to be impact and abrasion resistant.
From a quick read, perhaps a few layers of Diolen with Carbon top layers? Help keep the cost sensible.
I'll probably line it with either sheepskin or foam
Is that enough to get started?

Thanks chaps.. sounds like good, solid advice. I figured that the internal foam padding would be about 5mm thick. And if I sanded the edges round, that should minimise the risk further.
I think I can probably get an idea of the materials best suited from the posts here, is there an idiots guide to actually getting the thing done once I have the mould?
If anyone feels like estimating a cost to do it for me from the mould I make (not sure if that's allowed here, apologies if it's not cool) feel free to pm me..
You really need to decide how you are going to make the final part before making the mould ie wet-lay, infusion or pre-preg as this will have a baring on how and what the mould is made from. Looking at your sketch, because of the wrap around design it will have to be a split mould otherwise you wont get the finished part out of the mould. With infusion or pre-preg you will need some flanges on there as well. If you plan on outsourcing the manufacture I would talk to whoever is going to make it as to what type of mould they suggest. One problem area of outsourcing is that the "fit for purpose" responsibility would fall on their shoulders and they may not want that risk.
