Hey All,

Im new to this whole Carbon work and thought id buy a mould making and laminting kit from easy composites.

Now as my first test of how this all works im attempting to make a carbon replica of my B&M Shifter cover..

A few questions:

1) am i best to cover up and smooth all the edges with plasticine / wax filler ??

2) am i best to use the wax mould release on this and lay carbon down onto it OR

3) am i best to take a mould of it and smooth the mould out with wet and dry before laying the carbon down on the mould..

Below is some pics of the gaps and cover in question...









Once and if this comes out well i will attempt to modify my existing dash and remove the gauges and recess my digital dash into it..

There's no real limit to the amount of layers you could laminate and then vacuum bag. If you're referring to resin infusion rather than vacuum bagging then, although you can certainly infuse very thick laminates, there would eventually be a limit to how much laminate the resin would infuse through. It does depend on the type of reinforcement - some, like 2/2 twills, flow much quicker than others, like unidirectionals. You can certainly infuse several millimeters of laminate, providing it flows well enough, which could be 10+ layers of fabric.

It's also worth noting that some infusion resins, like our IN2 Epoxy Infusion Resin will flow slower than others, like our IP2 Polyester Infusion Resin, which is considerably quicker and will therefore be able to infuse through thicker laminates. It's often the case that projects that use much thicker laminates, like a boat hull for example, would lend themselves to a polyester infusion resin whereas thinner laminates are often for higher spec projects and are therefore more suited to epoxy infusion resin.

I hope this helps.
