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

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.
I left a small amount of the flange 30mm to allow the bonding the scoop to the inside of the bonnet using the flange, it made for a really easy installation just add black polyurethane add some weights and let it dry Smile



BTW: If you need the scoop extended in height 30mm ish taller than the original (I needed it taller as the stacks and air filter on my hayabusa engine were squashed on the inside of the scoop)
You are welcome to borrow my mould it's a quite large mind. if you want to come and pick it up and drop it off when you're finished.
