23 minutes is an impressive time to build a trunk lid. That would take me at least twice as long.

[@funnyvideosrandomvideos3963]

It’s sped up?

[@Freedom_is_better_than_safety]

No kidding. If it weren’t for time lapse, it would take me way longer to get things done.

[@98Fencer]

pretty sure its a joke guys. XD

[@elissitdesign]

Oh I thought he was the Flash.

[@mndlessdrwer]

This is exactly the kind of methodology I was hoping to see. An outer beauty panel with an inner structural panel bonded to it that recreates the kind of skeletonized raised support structure that companies make with stamped steel in order to use tensegrity to add additional rigidity and support to the panels. Those molds are beautifully made and the gel-coat in flawless. I appreciate your efforts to really work the carbon into the creases and contours of the mold with the spray adhesive to ensure that you have enough material packed in there for the vacuum bag to work with. Beautifully done, this should result in an inordinately strong part that weighs considerably less than the original despite being an order of magnitude stronger.

[@KNABuilds]

One tip to avoid a sanding operation. Remove your parts from the mold, do your trimming and hole cutting, then remove the peel ply when you're ready to bond the parts together. That should leave you with a good surface for bonding without having to sand. That's how we build airplanes out of composites. You only need to sand if you remove the peel ply too early and let it get contaminated.

[@tombeasley1943]

There are two types of Peel Ply in the industry. If you use the type for bonding then the surface finish is rough. I would imagine he's using the type that leaves a very smooth finish. Thus the need to sand before bonding. He's been around the block on making parts, so I am sure he knows what he's doing.

[@vikassm]

Question: Why follow the internal ribs and contours of the original sheet metal part? They're there to add rigidity while conforming to the limitations of press machines and welding requirements. Why replicate those exact shapes on a one-off hand-made part? Any external surface must be the exact shape for obvious reasons (Originality and/or aesthetics). Only the mating internal surfaces need to follow the original design... Painstakingly re-creating the internal surface structure seems redundant. Any thoughts?

[@dinguth4695]

@@vikassm because he did a Mold of the entire inner support areas. Doesnt want to go through all the extra work of modifying things when the inner stuff already has great mold quality paint. And these arent one off. He sells them to people that want to buy.

[@nonotorious1467]

@@vikassm For mounting points, electrics and what not. I doubt every part is going onto a car that's track built.

[@doubleT84]

@@vikassm Without the inner part you need some kind of other structure or the outer part alone could wobble and bend diagonally. It also helps to build some thickness. Pretty sure the part even with the inner will be shallower on the body of the car than the surrounding original parts, though.

[@jchack88]

I have zero need for a carbon fiber trunk lid, but your work and craftsmanship makes me want.

[@drobekmh]

It looks amazing 🥵 Every time I see your videos I want to get into making my own pieces, but I know it's not as simple as you make it look

[@andretorben9995]

The only problem I have with this video is that he makes it looks much more simple that it probably really is. Very organised workspace and a very professional product. I'm impressed !.

[@ashrafmraish]

Thats impressive, excellent work man, i highly advise you to make carbon hood and fenders for new supra. The market is full of bolted fiber glass parts but if you can make a complete part that will be a great business for you. God bless you

[@jahwerx]

Always knocking out of the park. well done!

[@DatsunZ73]

First time seeing your videos. I really appreciate the attention to keeping it clean all throughout the process. Keep up the beautiful work man!

[@WildDigger]

Awesome work! This makes me want to carbon my entire Z4. Lol.

[@takwinsulaiman4382]

hello sir.. I'm a newbie to this method(carbon fiber infusion) Can i ask u few question about the process u did in the video: 1- what clear coat do u use sir? 2- what is the oven temp' u using during the curing process? 3- how long(hours) does it take to full cure the Trunk? 4- do u close the "vacuum pump" after the epoxy is full cover the mold or u just left it running until the trunk is full cure? 5- what glue type(bonding agent) u use to combine the Trunk? That's all.. sorry sir for too many question asking Your answer will help me a lot.. Keep up the great work u do sir :)

[@angeloc700]

Wow, that's a lot of meticulous work! I would totally destroy that panel at every step of the job... Nice work!!

[@OscarGonzalez-ix7dj]

wow thats amazing i always wanted to see how carbon fiber parts are made now i know its a long hard labores process i want 2 get as much carbon fiber on my car as i can 2 make it lighter after watching this video i have a new found respect n admiration for carbon fiber and your work u r a very good craftsman

[@petercunningham5820]

Holy crap. Next level man. Great job.

[@williamlanphar630]

Watching the time lapse infusion is so satisfying !

[@RiazRJ]

Love the setup you have, question when trimming the panels how do you dispose of the carbon dust you collect from the vac?

[@slablife]

Great work! I'm about to try this for my 1961 Lincoln Continental, so this was ver helpful.

[@denistremblay4713]

Such nice work, you make it look so easy to do. Very nice work.

[@jayk7781]

Fantastic build!! Thank you for sharing

[@minikhy7835]

I love watching your videos, I am looking at getting into doing this for my self as a result. I did have a question though from when you did the outer shell, did the resin really almost explode into the part where it went very quickly or was that just the time lapse? the reason i ask is because all the others seem a ton slower. Thanks for your time and keep up the great work :)

[@ajhartmanaero]

I don’t remember any issues so must have been Timelapse

[@juanvazquez8922]

Awesome work. Love to see the process. Do you have a video on how you made the molds? Also, have you considered making rear quarter panels for your new edge race car? I was wondering if that’s possible.

[@ajhartmanaero]

No on both. It’s possible but not worth it.

[@EngineeringSiblings]

Is there a reason why you dont leave the outer skin in the mold, glue in the underside (potentually you can use vaccum bagfor clamping) and only than take it out ? Interested to learn as that is how we did large assemblies in marine production to make sure the outer skin doesnt deform. Beautiful work by the way. A pleasure looking at someone doing such clean work.

[@ajhartmanaero]

Definitely a possible way to bond stuff. I pull them cause I don’t have enough clamps that can clear the depth of the flange. Simple as that.

[@DeeEhm]

Two questions: 1) I have seen some really great "maker" videos by you which includes product you sell. Is your goal to empower folks to make their own custom stuff or give folks a peek at what goes into the making of your parts? 2) The tactical vest. Seen you wear it a few times in videos. Is it a convenient place to store tools as you work?

[@ajhartmanaero]

1. Both. 2. Yes

[@WEIGHT_LOSS_Motorsport]

Great work looks amazing💪🏼

[@Dirtyz1234]

I built a custom steel hood for my Subaru Baja with a larger scoop out of a newer STI and have someone wanting me to do the same for their 22 Outback. These one-offs are not profitable at all so I'm trying to gather as much info about composites as I can in hopes of reproducing a few. Thanks for the good time lapse of the process!

[@charlysanchez143]

craftsmanship, good work!!

[@gorannilsson4452]

Did you let the clear cure before you put on first layer of the carbon ? Did you made any preparations of the cured clear before put on the carbon ?

[@freedomfriestv]

Excellent video. What thickness was the carbon you used for this layup? (huge fan of the plate carrier as a tool holder too)

[@gregmcnamara2563]

I was going to ask the same

[@seankettledon1331]

So is the process the same as fiber glass, very much a beginner lol sorry in advance

[@jaimeelias2388]

Hey love your work but i use the 3m high tack spray adhisive 71. Its for infusion its better than 77. The resin dissolves it ant pushes out......

[@doubleT84]

Do you always clearly see where to cut in the end or is there a risk of easily ruining the cut? When the trunk is installed, will it sit significantly lower than the (original) fenders surrounding it?

[@zezog6622]

I have question .why you didn’t laying the carbon fibre just one piece on ??

[@Octanejunkiess]

Great work love the craftsmanship wish you sold one for the crown Vic make my pos look a lil better

[@Dirtyz1234]

In my experience with panel bonding adhesives, it seems to be best practice to spread a thin layer to both prepped surfaces and then come back on one side with a bead of adhesive before clamping together. Probably nitpicking with the amount of clamps you use though
