Hello guys

im thinking to build owen and yo buy easycomposites pre pregs . question is where to buy material cutter and how to make perfect templates?


Thank u

Any wet lay glass mould will have some shrinkage when you make a pre-preg part. It will warm up and expand then as it cools contract back again. If you de-mould cold then the mould will not last too long if the mould is a multiple section mould. It can crack the mould after only 3 or 4 pulls. I have had that happen once. If it is an open mould and the part will come out easily then it should last for as long as you need if you look after it.. But a mould like my Fuel tank shell has to be de-moulded hot or I  have to have a pre-preg carbon mould if I want to allow it to go down to room temp. 

Cutting pre-preg is easy and I use a scalpel as I get 100 blades at a time and it cuts a very clean edge too.
