after returning from work i found my part had still not cured properly. i done it at 10 pm last night. i decided to remove it as i assume something wasnt right. its also stuck to the mould slightly as it hadnt cured properly and theres some epoxy still stuck to the mould.

Argh, sorry to hear that, Jap.

I can say that cos I've been there too, and too many times to mention: at least you learned one way how not to do your stuff

All I can suggest is you to put a drop of resin on a plate, or in a liner, and set it next to your curing part so they both cure at the same temperature. Just a little drop, since a bigger volume of resin will cure faster than your part.

You can check if your drop is cured by trying to force your nail in. If its cured, your nail is not supposed to leave an inprint. And if your drop of resin is cured, then your part should be.

Also, notice than resins cure time are given on a defined temperature. It might be slower to cure at lower temperatures. Thats why the "nail in a drop" test would be usefull for you to be sure.

You can remove the excess resin in your mold using a plastic tool, like a bondo spreader for example. Plastic will save your mold surface finish.

Keep on trying, good luck

yes time to start again i think. im also going to purchase the fast hardener so i have the option when it comes to different sized parts. ill let you guys know how i get on

Sorry to hear of this one,

I think we have all been there at some point, being impatient and trying to release a component too soon is easily done, it's worth noting that our fast and slow hardeners are compatible with eachother so you can mix them together at any ration to get different speeds.

unfortunately youve learnt one of the most important lessons of composites the hard way - dont rush.

Hopefully it will work out ok next time.
