Hi, 

Newbie here. I am trying with making a part and i can't get rid of the bubbles. 



I usually get a lot of small voids and few huge bubbles. I prepare the mould with 5 coats of buffed wax (Axel PasteWiz) and a layer of PVA for a sure release. I heat the mould with a hot air gun and also heat the mixed resin and hardner. Then i apply 6 layers of carbon fibers, heating in between every layer. 

Any idea what I am doing wrong?

I agree with the other posters ..   Small parts with tight corners do not mix well with medium weight cloth/fabric and wet -lay ..

As soon as you have vacuum or infusion, and prepare your "stack" well, most of the bridging and trapped air will not be a problem.

To wet lay small parts with small radius corners, you really do need to use light weight CF cloth -  Also Plain weave is harder to get to follow complex shapes and compound curves than Twill weave.
