This made me laugh out loud 😂hahaha

HAHHAHAHAH I should title my autobiography "pure pain and underwhelming results."

This is the real deal. Some channels show the exact opposite and can ruin your outlook on your current projects. SFM makes me feel ok again. Not at all in a I'm better kind of way. Just real struggle and working through it.

Pain and underwhelming results are a way of life! 😆

What ab epic comment!😂

I live in Bulgaria now. I just got some old built-in wardrobes from the communist era, just to reuse the chipboard for garage shelving. Communist chipboard was REALLY good. For starters its unbelievably heavy, and its incredibly dense. Nothing like the fluffy stuff we get today.

That was my thought too. Looking at those cars all I could think was a nock-off Chippendale cabinet made from OSB.

​@piccalillipit9211 you can still buy the stuff in higher or lower densities and longer shorter chip/fibers, same with mdf like materials. You will just pay a premium for stuff that isn't made in such huge quantities.

@@miles11we Im aware of this - but this stuff is off the charts. Its much more like a composite in that there are NO air pockets in it, its 100% solid in cross-section. I have not seen this stuff in the west - it might exist, but Ive not seen it.

@@piccalillipit9211 you mean Medium-density fibreboard, MDF

seriously, if you arent making an F1 car and you can see the thickness of the part, its too thick. Maybe even on F1 cars.

I vaguely recall that quote, but can't remember what it's from. (Stand-up? Movie?) Can anyone help me out?

​@@rmichaeldeutsch If you're looking for where the "is 4 a lot?" thing comes from, I think it's from Dr Who.

“…you’ll still get high on the fumes though…” Matt: “Excellent, thanks for sharing.”

I came here to say this, as it should be a simple layup on foam blocks with rounded corners. I can not imagine a more difficult way to go about this, and yet that didn't stop me from enjoying every minute. Can't imagine what making the shell will look like.

Let's hope present Matt finds the time to read at least the first few comments

I would probably just have made a two part mold in 3D print for the exterior (with generous draft because it didn't needed to be rectangle anyway, only rectanglish) and wrapped wet carbon around the bag, the pressurize it from the inside. This is essentially how they make carbon fiber bikes except they use non-autoclave prepreg carbon and oven it. Or you know, just 3d print the parts and call it a day.

Another thing is that the outside doesn't need to be vacuum bagged at all. You just wrap the whole thing in wide electrical tape (PVC tape), this squeezes out the excess resin while also keeping any wrinkles from forming as it's compressive. and as it doesn't absorb any resin so it's easier to remove.

Thank you for sharing!

Awesome, you probably watched Mike Patey building his plane then if not worth a watch.

What a lovely little story!

"Glancing over to the table I saw that we had made a nice container of fire." My lord, I got tears in my eyes :)

Is the plane red on top and white on the bottom, with an orange and purple stripe twisting along from the nose to the tail and N919HB just in front and down from the horizontal stabilizers? Number 67 in red on the wingtips and in white on the rudder? That's an awesome looking machine, I have to say!

you could prolly go thinner with drain spec pvc

it then he has no content to make videos with. We'll he has, but couldn't be arsed to work on it.

Turn the closet heat up. Soften a 4" pvc drain tube. Blow it I to a 4x5 ID Wood box. Trim to length.

​@@jimrobcoyle This is the way.

I think this was supposed to be practice for making the body

I would have just used 5" drain pipe and reworked the tail to fit. But I'm not Matt. And nobody is watching me make a mess with my projects.

Whole holes are holy.

You beat me to it. Downspouts are available in 4x5 from my local home improvement store, in plastic *or* aluminum....

Correct otherwise it's just a sparkling reciprocating saw

Both of you deserve so many more likes 😂😂😂

Having been forced to work with a number of various engineers, I know that school exists ... and it's a BIG one.

like a math minor, you get the half assed minor for free when you major in engineering.

over engineering degrees are exclusive to german universities

it's the journey that's important

"Head, meet wall, you two will share blows for the next 2 years." - what I think any time I'm taking on a project that I know is out of my depth and I lack the education/experience to do without 100+ iterations.

One must imagine Matt happy

It gives me anxiety, sometimes I can’t watch. 😂

i reckon this is why the channel is successful, subtle humour

I read that as Source Film Maker lol

Source Film Maker?

Doesn’t that make Matt a full ass?!

Nobody wants to see that! That's four times the ass!

Yeah I agree vacuum is too much trouble because weight is not an issue. Just go wet layup and a big fat flood coat. Its so much easier to do and gives good results.

Brother I have wet sanded by hand a fiber glass mold in stages to 8000 or 10000 grit paper? Absolute hand murder but fun trick, make a squiggle in Sharpie before you go down a layer once you have uniformly sanded down and the marker disappears you can go to the next finer grit

When working with short glass fibers for thermoplastic composites, one learns rather quickly to be very careful when going to the bathroom. Switching to continuous fiber was very welcome.

Itching is loving, breath and skin protection is caring.

I've only ever worked with chopped strand fiberglass once (built a custom shower tray for my camper conversion), and it was the stickiest, itchiest, smelliest, most unpleasant experience. Ever. I don't know how anyone could work with the stuff full time.

@@InternetListener Back in the 19and70s, we were MEN! We eschewed PPE and despised those who used it. Most seat belts of that era were NEVER removed fro the plastic bags they were put into.

@@oddshot60 And you are all dead from emphysema now , aren't you , Mr Zombie commenter?

You complicated this far too much. After watching a few minutes: Find a cardboard tube with an OD near what you want for the ID of your tube. Coat the tube exterior with clear packing tape to create a surface that releases easily. Create 4-5 wooden bulkheads to insert in to the tube and create the shape you are looking for. Put it all together and you have a cheap and easy to make (saccrificial) buck. Since you aren't concerned about strength, go resin rich on the carbon, wrap it over the buck (after applying a good coat of carnuaba wax for a release agent), then add your peel ply and some of the matt used to absorb the excess resin. Instead of a vacuum bag, just wrap the whole thing with duct tape or even rope to squeeze the assembly. Once cured, remove the tape and see if you can get the peel ply off. Hopefully it won't be too hard to remove. For the interior, pop the bulkheads sideways to get them out if you can. If not use a large hole saw with an extension to cut out most of their centers, then throw the whole thing in some water to turn the cardboard tube in to mush. After it's mushy, tear it up and pull it out in chunks. That's the process. I would make it a bit long so I could cut the ends clean before trying to remove the interior buck. I would also wrap the peel ply and matt around the exterior of the carbon in the shape of an "e" with a little bit of plastic in the overlap where it wraps over itself so you have some peel ply without resin to grab on to and pull to get the release started. You might have the same veiny exterior but that's what Bondo and palm sanders are for. Hopefully the interior would be smooth so your parachute will release too.

In this case, only the inner surface matters. The outer surface is not visible when the bodywork is on, and the parachute needs to slide smoothly out of the inside.

@@brianb-p6586 but he also mentioned that he didn't care how the inner surface looked. And you'll get a clean smooth surface anyway. So I'd rather have a simpler method in terms of molds and a nice looking outer surface as that's the one you're going to see when working on the project.

Look at that, Frosty the Snowman melted. We must be living in the End Times for the Snowball of Secrets to disappear like that

well forged carbon is a GREAT material for uses like high performance delta 3d printers (I've dabbled...) because it is stiff and lightweight since it's a fiber composite, and the forging process allows for more fiber density and more 3d geometry. The thing that engineers dislike about the forged carbon is that it is exactly the wrong material for for example a car hood, since for a part that flat and big woven is just better in almost every way, while imo looking better. I love forged carbon and use it, but I always cringe when i see cars use it in hoods etc.

@@cozmo4694 Oh yeah 100% agree, it’s even worse when people make wings out of it, horrible material properties for that kind of load

I did that on a recent project using an ABS mold and dissolving it with Acetone. It was wonderful!

Either that or just make a weak part and strengthen it with a composite layup.

To be fair you don't need to be perfect to pass a state inspection, just good enough for a half-assed inspector

@@Hawk7886 and also the shop that I took it too for inspection is owned by the family that runs the local autoX that I go to.. BUT ITS STILL IN THE CAR AFTER A YEAR SO I AM A FUCKING GENIUS Lol

Why does full vacuum draw out too much resin from a wet layup, but not for infusion?

Don't do the vacuum bags. Just go for a wet layup and be very thorough in removing all the air bubbles. It will be fine.

Agreed this could be pretty easy but I would make sure to fillet the corners to the flange with thickened epoxy because the fibers won't bend in there

Carbon would actually be worse for a body because it's hard, brittle and it shatters into black needles than want to attack your skin. A glass fiber composite would be much more resistant to vibrations and it would be way more flexible. On top of that, when it fails you get chunks of epoxy held together by hairy stuff. Way less intimidating.

@@ThaJay Maybe Diolen would also be one cost effective option. It's an aramid fiber and is quite shatter resistant, it's kind of a cheap mans Kevlar

The whole bubble removal is for casting, I don't believe in it for laminating or coating.

@@ThaJay Good point. Im quoting my friend. Its a dead simple way to remove bubbles/foam. This is my two cents. Bubble physics is a bit weird. They form from super small bubbles to form larger, visible ones. If you can eliminate the microscopic bubbles at the mixing stage. Its going to be beneficial at any later stage in the process.
