Hi all

I am new to mould making at home and to this site

I have a Uni-Mould kit from Easy Composites and have made a pattern for a kit car scoop using my original scoop from the car see picture attached

I would really like any tips / advice you may have on how to prep / release the pattern before making the mould

I have read instructions sheets and watch videos BUT would welcome any contributions as you cannot beat the experience of other people that have started out the same way

For example I have a block of filleting wax to use where there might be some under cuts but do i put this on before or after releasing the pattern

Thanks in advance for any helping a newbie

Regards
Ian

Hi ian

I usually release/wax a mould first and then add any yellow wax filling or fillets etc.

Hi

Thanks Scottracing and Fasta for the advice.

I have created side flanges all around by mounting the scoop on a flat board and now applied fillet wax on edges/joints to stop undercuts.

I have easylease and Mequires no8 wax to use on pattern.

However I am now thinking should i raise the scoop 5 to 10mm off the board in height all round to give that extra to trim back
(Thats a good shout Scottracing)

I also have some PVA as well so i might add some of that Fasta as i don't want to ruin my existing scoop (incase i am no good at making a new one !!)

Once again thanks for the help, I am now off to the shed for rethink.

I always apply release agent before doing the wax to ensure complete coverage, then apply another couple of coats afterwards in case any was removed when I was applying the wax. 

Looking good the flange on the back end of the scoop is looking a little small but that could be the picture.
I usually aim for about a 4/5 inch flange to give plenty of room for layup | peel ply | infusion mesh and the infusion lines.

In regard to the raising it to have something to cut off unless you need the extra height for a plenum or to stop the engine fouling the inside of the scoop, I would leave it.

HI Hanaldo and Davro

Thanks for the advice I will add an extra coat of release now I have done the wax.

Also Davro thank you very much for the Loan offer on your mould, that is really appreciated However I am really up for making a mould which I am going to do this weekend and hopefully it will be usable (fingers crossed) and doesn't right of my original scoop.

I am really looking forward to experimenting with carbon composite.

Hi All

Just a quick update have just made and broken out my first mould and must say am very happy with the results see photos test 1 & 3.

I was worried that it would stick & never come apart again loosing my original scoop but followed instructions / advice given me on here and came apart so easy with an excellent finish and shine for main component area, apart from flanges .

Only one little bridge / loss of gelcoat say about 60 to 70mm long on a edge (might try and fill) as shown in photo test 2

Thanks again for help

Regards
