Nice job and really nice finish out of a mould!

Absolutely incredible what you doing mate well done 👌

The finish looks great 👍

Thanks for the videos! Really good quality. And u r inspiring me to develop my own parts 👊👊

Your videos are really informative and I appreciate the level of detail you give on explaining things along the way. I know you mentioned that people ask exactly how you create your molds. I would love to see your process on that. Keep up on the amazing videos.

Love all tips and tricks you give to make the process that much easier for someone to have a go themselves. How long did the whole infusion process take in the end, I couldn't see the clock very well?

yes you are absolutely right, vertical setting is the best against air bubbles !!

Very informative video. Thank you for the details and explaining the why and how of different steps.

I wish I was as good at what I do, as you are at what you do. You are an artisan ♠️

Absolutely awesome job guys 👍 great Videos 👌

Absolutely I appreciate all your Tips and great 👍 Video's 😎🤙

Amzing bro.. love your work

Should make a video of how you make the molds, very interested in that!!!

Could you go over how you mocked up the original roof panel to make a mould and where your bolt holes would go? Unless your existing car already has the roof cut out. Thanks!

Another great video. 👍

Awesome information thank you

Great video. What is it that you spray on before each layer, some glue of some sort?

great work sir

Awesome 👍 job guys

Perfekt.. i build the same roof for my 92' civic.. but your roof looks so pretty smoot clean after you take it out of the mold.. do you don't take a topcoat layer for UV resist?

Hi, great job !! Which mold coating do you use ?

How is carbon fiber waste disposed of? Thanks for these videos, I would like to make an MG Midget body.

Is it possible to make a mold from the painted hood (plug) of a car without damaging the finish? Would multiple layers of wax, then PVA be enough to protect the paint? Could you use polyester GEL coat or would an Epoxy GEL be less damaging? I guess, if the wax-PVA layer is perfectly applied, there would be no problem. Great informational videos, best on the web. Thank you for producing them.

so i wanna make a carbon roof for my SC400 as well. do you think it's absolutely necessary for the roof skin to go all the way under the windshield or just panel bonding it to a 2" section of the original roof would be ok?

What’s the coating you spray after applying the release wax?

I saw your video where you installed the carbon roof, if i were to drill out the spot welds and try to repurpose the roof for my mold, would i just have to be extremely careful not to bend the panel and take my time?

Nice job, talk about patience, I have no patience when it comes to doing that kind of a project

I see sometimes you spray a clear on the mod. Is this best practice to do it before hand? Does the part come out visually better than doing it after the part had come out the oven? If you spray the clear after the demolding step would you have to wet sand and then polish since it might have orange peel?

Great

at the ending time you car rotate the part slightly in the clockwise direction so the the right dry end fills earlier due to gravity!

Hi brother what is the in mold coating? Is it clear coat or epoxy thanks

So please help me understand what it is that you are spraying in the mold for clear coat is this like a 2k automotive clear coat? if it is are you letting it fully cure before laying in the carbon? if so how dose it adhere to the epoxy? or is it more like a clear gel coat?

What type of in mold coating do you use? I need it for my parts!

Great video and extremely informative and professional. I want to replace my headliner with a carbon fiber shell. To eliminate the cloth lining from falling apart. Could it be done with an insulating backing between the liner and the roof?

how strong of a vacuum pump are you running to pull that epoxy up hill?

Hi, do you Degas the Epoxy Resin?

Жыл бұрын

in this case i think its a gel coat / clear coat. some spray mold release like that prior to layup. I've also heard of, but never seen, primer-in-mold, essentially being able to pop a pre-primered panel straight out of the mold. In this case the clear is probably for UV protection. I could be wrong.

Love the videos! Your finishes are amazing right out the mould. Was curious as to why you don't clear coat your parts? Where I work we always send parts out for clear coat after sanding. Do parts generally hold up fine against the UV and weather without clear?

On bigger and more complex parts, eg: a body tub, it might lead to problems, but on these, it definitely does work, with good results. Please post the link you mentioned, so we can see.

With that inlet diameter, normally a travel of 500-600 millimeters max. is adviced. After that, a second inlet in the middle of the mold is necessary if one wants to stay safe
