I'm sure Nylon would be fine on a low stress part like that though.
You might even be able get one off the shelf based on the id.
Is the peg cf too? Or aluminium?
I'm just interested if you have a bleed hole in your mould press, for surplus resin and air to escape, or if you carefully weigh out just the right amount of resin?

Yup peg is turned cf.
No bleed holes, you need to calculate weight of fiber carefully (if the volume is say 100ml/cm3, the density of forged CF is 1.4, so 140 gms, of which 60% needs to be fibers in this example 84gms, the resin volume needs to be well in excess of the finished %, and the excess will be forced out of the gap between the mould halves as you very slowly compress them together giving an opportunity for the fibers to move. Easy Composites do some excellent vids on youtube on the subject, in fact they taught me all I know.
