You have got me thinking now Glen.
Going to have a go at laminating the carbon fibre sheets together to make a losmondy d type plate.(only 200mm) long + light weight for my travel scope.
Seems you can machine the carbon fibre similar to metal only the router and drill bits will dull faster. You also have to use slower feed rates as it is a hard material. Thanks for the inspiration, I'll let you know how I get on the next couple of weeks.
