Finished my Outlaw Speedster

This is exactly how it's done at the Metropolitan Museum of Art in their reproductive mold making shop. I took two semesters with them when I was in school. It was a graduate course and I cheated to get in it as an underclassman. One of the best classes I ever had in anything.

Go Marcel!!!

Marcel.........Could you use liquid rubber to make the mold ?  Perhaps support it with a fiberglass backing ? The rubber, when hardened, would be flexible enough to remove from the inside of the casting...........Bruce

Umm, exactly what are you guys making? Sex toys?

Danny........Nope....Just an Air Cleaner for my Spyder..........Bruce

This two part rubber  used in my moulds above are used in the movie industry to make all kinds of props. It comes in different densities and is easy to use.  I use ball bearings to form my mould alignment pins because they are perfect for ease of mould separation.  It's way better than Flex-Seal.  Less expensive too, due to the volume required for most projects.

I have painted this rubber onto a pattern in several layers then painted fiber glass resin over that.  I apply layers of fiber glass  for rigidness/support of the rubber layer. When rigid enough and supported with ribs at strategic areas, I remove it from the pattern by splitting the mould between the flanges I made on the fiber glass layer.............Bruce

Nice skills!

Cool! But I have no experience with these rubber compounds, so I'll just stick to what I know. Polyester or epoxy resin with glassfibre reinforcement.

The DTM shroud is a lot simple casting that yours.  You can see several bonded seams and there are quite a few vanes/deflectors pop riveted on separately.

Stick with what you know Marcel.  By the way, I only sand the mould surface down to 1000 grit then go with the Maguires Mould release (3 coats). This leaves the surface of your finished product with a "matte finish". The matte finish can then be sanded with more 1000 grit to remove all the mould release and allows a good surface for spraying on what color gel coat you choose. For coloring the resin I use any 100% acrylic artists paint found at an art supply store.  It doesn't take a lot of it to get dramatic results either.

Eat, fill, sand, repeat…..

I hate this stage……but needs must.

the backside will be the most interesting to look at, but no-one will see it in the car!

Hah!  Anyone who's worked with fiberglass knows that routine...

That is a work of art!

It should be, "Eat, fill, sand, scratch, repeat…"

Because we all know how fiberglass makes you itch when you sand it...

First time I actually parked the car to make some pictures. I love how the shape of a Speedster just works from every angle.

Car looks great, Marcel.

That is a VERY well done Outlaw, @Marcel

Nice

Wow! Fantastic!!

Really makes a statement! Beautiful job.

@Marcel I'll have to agree with everyone, pretty cool car.

I do have one question though. What are you running for tires?

I only ask because a few of us have been running, or going to be running, Vredestein Sportrac 5 tires. As this is a company from your part of the world, I was just curious what sizes are available to you? From what I understand, this company is not sure if they're going to keep on making, or importing to us, sizes that we'd be able to use.

Just wondering.

BTW, I'm going to get mine mounted tomorrow.

That really does look like the one that Rod Emory produced.  I've admired that build for a long time...

Well done!

@Marcel, did you flare the rear fenders a bit for larger tires?  It looks that way in a couple of pictures but it's very subtle.  If you did, very nice work.
