For a first go that's not bad at all. With any new mould you probably have to allow for the first couple of pieces to be less than perfect, as you iron out the particular requirements of the lay-up

I'd certainly recommend using the Easylease release agent and being very generous with the number of applications on a new mould.

I realise i did several errors with this mold.
One of them was not waxing it properly with the release wax.
Took some time to get the part out



Also the carbon had not bedded properly to the mould, so the glue was on the outside of the carbon/twaron



Im in the process of masking over most of the errors now.
This is a piece that sits under the car, so even if its not that good looking ill mount it and see how it wears and tears.

Infused it now, and i mixed up resin according to the calculator.
That was precisely enough for the part... which meant that when i was about to close the feedline i moved the hose and lots of air was sucked in... :+\
I closed the feed line and kept the vacuum pump running for a while to get rid of most of the air bubbles before i closed the other end aswell.

Ill post a picture tomorrow of the cured part.

Thanks, i did as you suggested, and now i was able to get proper vacuum.

Hi Ronny

Since its on the underside it will take alot of beating, thats why i was wondering about using EF80
If you look at this picture


The side is in fact rubber on the original item, so it will bend upwards if you hit the road with it.

Now i have tried all evening to figure out one tiny leak.
I had several leaks which i all found by putting my ear into the mould and listen.
But there is at least one more leak which i am unable to find, any suggestions?

This is the setup


Gauge stops here: (closing the pump causes the vacuum to drop)



I actually found one leak that was through the whole mould ?!?


How do i prevent this in the future? more careful when applying the tooling resin?

Looking good, shouldn't take too much work to correct.

can I ask why you mention flexible resin, from what I understand its VERY flexible.

Beeing not as patient as i maybe should, i have just removed the mould.
Since i made it on a sheet of polypropylene which i also had waxed it came of witout any problems.

I made quite a mess, and see several things i could have done better, but i believe with some proper afterwork i can make it usable.
The gelcoat had found its way under on a couple of places, so i needed to cut the mould slightly



So next time ill make sure to be extra careful when adding the plasticine barrier.

Other than that the part came loose pretty easy without any damage.



So now its time for a lot of cutting and sanding before it is twaron infusion time.

Has anyone tried to infuse using the flexible resin? EF80

Now its been approx 4hours since i put on the tooling resin.
I've been feeling ut up now and then as its supposed to reach 50-60 degrees C, but now its really hardened but theres no temperature change.


Color is now light brown

Thanks, that hardened really quick, ended up with panic pouring it all over the mould.
Now its just to wait for 24 hours before either the part owner gets his piece back or i have to fork out 100£ for a new porsche part :p

Or can i remove the part from the mould earlier than after 24 hours?

after coupling coat


After tooling resin. used all 1200g of resin on the first two 450g layers, so i mixed up another 300gs for the third and final 450g layer.
