Thanks for the help guys, I think I will try both ways and see what turns out the best.
I will post pics of my progress, unless it's went embarrassingly wrong..... 😊

As Hanaldo said, sections that are vertical and parallel to each other can always be tricky when it comes to releasing the finished part, not to mention getting your reinforcement down well to avoid bridging and air pockets
Looks like you'll need a fair amount of filleting wax all the way around to fill the gaps. Another option might be to first create a vertical flange of a cm or two all the way around the part
You'd then be able to add horizontal flanges to those that are flatter to the work surface and use less filleting wax to create a draught angle between them and the vertical sections of signboard you'd glued to the part. You could even just fix the part down to a large piece of acryllic sheet which would give you an even smoother flange area with no need to apply release agent to it.

Good to see you took care of that beer quick smart!
Shouldn't be a hard part to mould, your flanging looks like it will work. Just look out with those mounting holes, they look like they have a 0 draft angle and will be a weak spot on the mould, so might give you a bit of drama. Make sure what you do with the filleting wax has a nice positive draft angle as well, don't try to make it too vertical.

Thanks, I will try that, although it will be tomorrow now, as that beer that's staring at me needs attending to! Ha ha! Thanks again 😊

Hi best thing to do is use a photo hosting site like photobucket, resize the pictures to 650 dpi and then copy past the URL on here.

Hi there, I'm fairly new on here and this is my first time asking for advice, so go easy with me!
I'm attempting to make a mould of a car part for a friend and have come to a point where I'm a little unsure of what to do, or if I can even take a mould from the part!
I've constructed a flange for the part with fluted signboard, and plan on filleting all the overhanging edges and fill and smooth any securing holes also, but as I'm sitting looking at it, I'm starting to have second thoughts on whether I can even make a mould and have the part easily release! Any advice on what I should do next would be greatly appreciated.
I've tried to up load a few pics but it says I'm at or over the limit, even with just one picture. Anyone any ideas what I may be doing wrong with that, as I've only ever uploaded three pictures.
