How to fiberglass - Making A Mold

Music preformed and owned by jamwarmusic & used with permission. / jamwarmusic
Making a fast mold. Molds used for production should use Tooling Gelcoat and have at least 7 - 10 layers of fiberglass. For the video, I used regular white gelcoat and about 3 layers of fiberglass.

[@CarbonGlassMan]

Thanks man. I am glad you liked the video and the music. My friend James always loved hearing that people enjoyed his music.

[@CarbonGlassMan]

No problem, glad I could help. I am working on another channel with a friend where we will be doing a lot of fiberglass and carbon fiber work. It should be interesting to people who like this video. The channel will be up in a few weeks. Keep looking for it.

[@indiomechudo1]

GREAT VIDEO, I HAVE BEEB EXPERIMENTING MAKING A MOULD, AND HAD A HARD TIME PULLING IT APART, I GUESS I WAS NOT WAXING THE MOULD AS MUCH AS I SHOULD HAVE....THANKS AGAIN I LEARNED ALOT !

[@CarbonGlassMan]

It's a resin that is usually colored. It is UV stable where as most polyester resins are not. It also provides a sandable and paintable surface for fiberglass parts.

[@CarbonGlassMan]

Thanks a lot. I am really glad that you liked the video and the music.

[@pedromarques3539]

very good ! Simple and clear explanation of making a mold in fiberglass, this was exactly what I was looking for. Thanks buddy!

[@CarbonGlassMan]

I'm really glad that it helped you. I'll be posting more videos like this soon.

[@CarbonGlassMan]

Glad I could help. Thanks for watching.

[@CarbonGlassMan]

Me too. He would have been happy with the exposure his music was getting. He use to tell me about emails he would get from people that watched this video and loved his music. That was when there was less than 11k views. At 85k views, he has missed a lot of emails from fans.

[@CarbonGlassMan]

@guidofernandez It is chop strand matt so tearing it doesn't hurt it's strength. It's just short strands of glass held together by a binder so it can be made into rolls and sheets, but the binder dissolves when you saturate it with resin. A single piece conforming to curves like in this part would have wrinkles that want to stand up. This is basically a way of adding relief cuts to the glass.

[@Spongychris]

Nice Tutorial! I have no such experience but learned from your video ! Thank you man.

[@CarbonGlassMan]

Thanks a lot. My friend James was really talented when it came to playing music.

[@CarbonGlassMan]

Thanks man. You can buy Gelcoat from local composite shops usually. There are also suppliers like CompositeOne and Fiberglast(dot)com (that's the correct spelling, not a typo). Local shops will probably be a little cheaper though. If you have any other questions, just ask.

[@colbeyw]

Awesome tutorial, answered a lot of my questions. Great Music as well

[@colbeyw]

GunsNpolitics What kind of resin did you use? Brand? Polyester? Epoxy?

[@CarbonGlassMan]

***** I'm not sure of the brand. It's what I use at my job. It's polyester resin.

[@allmypassionsallmylife]

I have watched a hundred film about fiberglass. This one is perfect. Great. Thanks a lot! ;)

[@drkrishna2020]

Very well done video .. thanks for uploading !! And fantastic songs in the back ground !!

[@mnp62]

I replay this all the time just for the music. It always angers me though, what he did....he was so talented.

[@CarbonGlassMan]

Thanks! I'm glad you enjoyed the video.

[@CarbonGlassMan]

I appreciate the comment. No offense taken. I did this video with what I had around at the time. This was also about 3 or 4 days of recording. This is not how I usually do this kind of work, but it made for a nice video that will help people get started. At least spark their interest. That was my hope anyway. I will check out your channel.

[@kenmorto]

That was a cool technique around the cut in on the bottom, (the inside radius), first fibers laid down!!

[@CarbonGlassMan]

@reamz22 I am glad you liked the music. My friend who wrote and performed the music passed away last November. His channel name is jamwarmusic and is still up. You can listen to several of his songs there.

[@seekerout]

Excellent! I liked the music too.

[@CarbonGlassMan]

@guidofernandez Cloth gives strength in just 2 directions. You turn cloth layers 45 degrees when you layer them to get strength in 4 directions. Chop strand matt is strong in all directions because of the random directions the glass strands run in. When I make a part that is only going to be 1 or 2 layers I always use chop strand matt because the part would be too flimsy with 1 to 2 layers of cloth.

[@CarbonGlassMan]

Fiberglass is heavier than carbon fiber but fiberglass is used for RC planes, so it's still a good material. The nose on my dad's untralight plane is fiberglass.

[@ntech722]

Nice video man! im thinking about making a mold for a tom tom gps for my car and this video will help me through the process. Thnaks again awesome video!

[@jasuscaredo]

Thanks for you video! To be even better, I should shot that video with a clock to see the different operations time and intervals. I'm trying to built a mold but I'm having priblems with gelcoat. I believe that a sould let it cure a bit before apply the first layer of resin. The result is the roving smashes the gelcoat film (because I don't let it cure a bit) and the mold surface is showing in some parts the fibers...

[@mircea415ify]

Awesome and you buddy has some great music..

[@CarbonGlassMan]

Mike O Thanks. Glad you enjoyed it.

[@CarbonGlassMan]

Thanks man. I appreciate the kind words.

[@CarbonGlassMan]

Thanks man. I appreciate the kind words.

[@reginashuell773]

Thank you for the informative video and wonderful music. I will recommend this site to others.

[@CarbonGlassMan]

Thanks! Glad you liked it Regina.

[@CarbonGlassMan]

Thanks man. I am working on several new fiberglass and carbon fiber videos. They will be on a new channel devoted to that stuff so keep a lookout for a video on this channel where I'll announce what the new channel is. (I don't know the new channel name yet, I'm still just working on the videos)

[@CarbonGlassMan]

Thanks. I'm glad you liked it.

[@CarbonGlassMan]

I am happy to help. I am going to be doing a new channel dealing with more composite videos soon.

[@CarbonGlassMan]

You're welcome. I have more videos like this coming. Keep looking for them.

[@CarbonGlassMan]

Thanks. Glad you enjoyed them.

[@reamz22]

@ Guns Npolitics I enjoy the video reminds me of when I had to do my own molding. Loved the music by James Warren specially the song at the end which I think it's called "Seasons starting to change" thumps up and nice work OP

[@CarbonGlassMan]

You roll it right away. The color change is because I edited out the beginning of the rolling process and just put the end of it in this video. It does change color a little as the layers build up and as the resin starts to cure or "kick off" as I call it. I'm glad the video helps. Just don't get frustrated and start out with small easy projects. Use acetone to clean your rollers and other tools and also to get the resin off of you if you get any on yourself.

[@Meritace11]

Awesome man ,many thanks from mexico

[@CarbonGlassMan]

@averagemale2000 Glad I could help. Thanks for watching and rating.

[@Dave51262]

Great video. That mold came out terrific! Nice music too. Thanks!

[@CarbonGlassMan]

Thanks man. I appreciate that.

[@LowCostCncRetrofits]

Just built myself a small pontoon using melamine white board as the mould It all just reminded me how labour intensive and itchy the whole process is, haven't done any glassing for 10 years LOL

[@CooCuMbEr]

a lot of people dont know this but....... when you use glass fiber you need to make sure the fibers go wiggely so they intertwine to make it strong so just work it a bit with your brush

[@CarbonGlassMan]

Andrew Bobbin What do you mean by them going wiggly?

[@SuperJimthegreek]

bravo damian verry good work... dimitris from Greece!!

[@CarbonGlassMan]

It's not an absolute must to make a part or to make a quick mold but for best results you should use it (gelcoat).

[@mnp62]

Play this vid all the time just for the music.

[@CarbonGlassMan]

@MamoTheta It's no bother man. That is an air body saw. It hooks to an air compressor and they work really well with sharp blades. I have 2 ingersoll rand ones and a Blue Point but honestly, the cheap ones from Harbor Freight are just as good and cost a lot less.

[@CarbonGlassMan]

We can talk about something in the future. At the moment I have too many things going on to take on anything new. I am curious about your project. Do you have any videos up of your dolls? It would help to see what we are talking about exactly.

[@frankpineda1832]

Amazing job, I like it, thanks for the video 👍

[@CarbonGlassMan]

Thank you. I'm glad you liked it.

[@CarbonGlassMan]

@Buckley128 Search KZbin for "How To Fiberglass - Two Part Mold Construction - #1 Flanging" and watch that video. That is a better example of how a motorcycle tank might be done. Basically yes, making a part is just the same process. Everything that was done to the original part in order to make the mold, should be done to the mold in order to make a new part. To be safe, I wax heavily for the first 3 to 5 parts. After that the mold is "seasoned" & not as much wax will be needed. My opinion.

[@CarbonGlassMan]

@TheHiddenPart I'm use to it as far as the skin goes and I do wear a mask most of the time.

[@CarbonGlassMan]

Thanks. I am working on a new channel that deals with making fiberglass and carbon fiber composite parts.

[@CarbonGlassMan]

@FireArmsResQ I do make a hood scoop that's a universal non functional deal. I have a lot fo projects I want to start but never seem to find enough time. Of course, if I was pretty sure there was a big market for something I'd probably find the time.

[@CarbonGlassMan]

Thanks. I have more of these videos in the works.

[@kenr1767]

Nice technique. I might suggest gloves during the wet lay up because with repeated exposure a certain percentage of the population will develop epoxy skin allergies.

[@sheyshannow2065]

Thank you very much for such a great video.

[@CarbonGlassMan]

Thanks. I'm glad you liked it. I will do more like this in the future.

[@CarbonGlassMan]

@neacie71 This is a wet layup and one way of doing it. Probably the most common way of doing it. Kind of a generic video but it gives you the gist I think.

[@CarbonGlassMan]

You wait for the gelcoat to dry enough to where it is tacky or sticky to the touch but it doesn't transfer the gelcoat to your finger. If it is still transferring then it is too wet. Tanks man!

[@HighFlyer338]

Excellent video.. one to save. I like the fact you speeded up the sanding etc. It's the technique involved that's interesting. Need to know what to use inbetween on the INSIDE of a fibre glass cowl to make another so that the two pieces seperate easily. Would 'cling film' work? So sorry to hear of your friend.. his song is beautiful. I've just lost two good friends of mine. Life is so fragile.

[@CarbonGlassMan]

Do you mean to release the inside of a cowl? If so, PVA, which is a liquid that dries to a film will work for that. Thanks. I am glad you enjoyed the video. I will make more like this in the future.

[@CarbonGlassMan]

I used an angle grinder with a 36 grit grinding disk on it.

[@ephoe18]

informative... nice music. thanks for the video.

[@PridelessChickz]

Oh, I understand! Like I said, it may be a while before I'm done sculpting and whatnot, so just let me know when you're ready. Here's a video I made, but the sculpt i'm making will probably be a little smaller. The baby in this video is like the size of a four month old, so she's kind of big. /watch?v=4J30HNAT4Bs

[@adampettingill7216]

awesome tutorial video on creating a mould well done

[@CarbonGlassMan]

Thanks. I have a few others that are more detailed.

[@CarbonGlassMan]

@SuperJimthegreek Thanks Jim!

[@caferacer987]

Great video! Keep up the good work!

[@ankitsaxena213]

man... ! I loved the finishing and quality of that mould. u did a great job. I watch many videos but comment on very few. good job .. I would really appreciate if u could guide me on how to make mold for new body shells of remote controlled cars ? :D

[@CarbonGlassMan]

Thanks! I plan to do more videos on fiberglass mold and part making.

[@CarbonGlassMan]

Glad I could help.

[@CarbonGlassMan]

Glad it could help you.

[@traypowell5909]

simple vid to follow also great vids on the guns

[@g41thomas]

should you wait for the gel coat to dry before applying the resin or it goes on the wet get coat immediately after applying the get coat? Thank you in advance... Awesome video and love the tone!

[@g41thomas]

nice, nice music

[@jwoke]

Sorry for your friend buddy. loved the music. Overall great tutorial video.

[@CarbonGlassMan]

Josh Corporan Thanks man.

[@CarbonGlassMan]

@GasserGlass Thanks man. It was your videos that got me started in this so I had to mention ya. I must have watched your videos 100 times each trying to learn. I'd love any advice or help you could offer. I'm always interested in improving and getting better. I'll keep looking for your new videos.

[@CarbonGlassMan]

that is called a barrel roller. It's shaped like a barrel on it's side.

[@karremania]

What is the time between the fiberglassing and using the roller? On your video you see the mold turn more brown/yellowish, but what time was that after you finished puttin on the fiberglass? I've watched quite alot of guides and stuff now, but yours is very simple and clear. So later gonna do my first fiberglass atempt, hopefully your movie was enough to get it done :D

[@SuperMoDe55]

Good video, your friend sounds a lot like Faith No More.

[@CarbonGlassMan]

@averagemale2000 Polyester gelcoat, unsure of the name brand because it was given to me. Yes, MEKP 2% Polyester. I don't always use PVA, but I do use it sometimes. About 30 minutes to an hour. I wanted to do this video like GasserGlass use to do his since he got me started in this business.

[@sinoakoresident2133]

GunsNpolitics WOW U MADE A GOOD VIDEO for that fiberglass , i lovet ! ♥ Thanks for sharing :D

[@CarbonGlassMan]

+Sinoako Resident You're welcome. Glad you enjoyed it.

[@sinoakoresident2133]

hi babyGunsNpolitics, this helps a lot and i did it too in our house. But wait, i have to ask something about that "paste" u use to make fiberglass mat stick on the things u used. What is the name of that? What brand or howd you call that even if its not branded? According to hardwares i ask in our country, we don't have that, :( so i used PR1MERO brand to make fiberglass mat stick to things i used. But in your country howd you call it if its not branded and if it has a brandname? Thanks babyGNP♥ I'LL wait for you answer :)

[@scottmontgomery67]

Very frickin' nice!

[@CarbonGlassMan]

Thanks!

[@walkertongdee]

At last some music I can listen to,

[@CarbonGlassMan]

Thanks. The saw is called a body saw. That's what I've always heard them called anyway. You can get them from tool stores or a lot of hardware or auto parts stores. I bought this one from Harbor Freight. I seem them at Lowes and stores like that too.

[@punk28186]

Very nice work mate xD

[@CarbonGlassMan]

Thanks.

[@CarbonGlassMan]

Glad U liked the video. Sorry the music depressed U.

[@janpakx]

everything is helpfull but only one think you didn't explain which resin or epoxy I have to use?and also after first gelcoat how many minutes I have to do next coat?how long does it take to dry the first and if the first coat is wet no problem if I go to second coat?

[@1309cbr]

very very nice video

[@davidpechumer556]

great video. thanks for sharing your knowledge

[@CarbonGlassMan]

Thanks. I keep saying that I'm going to do more of these videos. I am currently working on my workshop, redoing it, and I plan to do some more composites videos when I'm done.

[@MADMAGIN689]

Going to try and replicate the bumper inserts on my 76 regal. Make new and stronger ones. Hey man call your new channel( Let's Mold 1). Well something crazy like that. Peace out

[@boxer5958]

Hey bro nice work and tune..i just started my 1st fiberglass project can u share a few tips on excatly how i get or make gelcoat and custom the color

[@MsQuickshift]

Nice video and cool music :-)

[@MADMAGIN689]

Great vid

[@tracychapman1000]

thanks for sharing the videos with us please i have two questions for you first one is how much time between the five coats of wax ? the second question why i found it hard to stick the fiber glass on the gel coat like you did now ?

[@CarbonGlassMan]

+tracychapman1000 It depends on the temperature, but basically, when the wax dries, wipe it off with a clean cloth and apply another coat of wax. I don't know if I understand your second question. After the gelcoat cures. It should be sticky to the touch without transferring gelcoat to your finger, BUT if it completely dries, that's ok too. Then you just put the resin and fiberglass on the gelcoat. It will bond chemically, so no need to sand the gelcoat.

[@alan12635]

excellent tut fab music

[@CarbonGlassMan]

Thanks man. Glad you enjoyed it.

[@alan12635]

was great and I will watch it again alan

[@moz-z6487]

very nice!

[@matthiasstephens2265]

Jerry Cantrell called he wants the music he'd never let anyone hear back

[@Buckley128]

Once you have the mold made, you basically repeat the whole process to make a dupe of the original, correct? Do you re-wax the mold with 5 layers every time you make a new part? I'm considering making a CF tank shield for my motorcycle, I just don't want to cause any permanent damage to the tank when making the mold, and due to the bulky nature of the tank, can't really make a 'base' for the mold like you were able to do.

[@accordance73]

hello Sir, awesome video but maybe you or anyone in youtube country can guide me in the right direction here. want to make a duplicate casting from a packing cradle that my rc lipo battery charger came in so i can make a custom holding bracket using the shape of the packing cradle. but its made of some really flimsy thin plastic. how would i go about making a plug/mold of it before i can make the final product out of fiberglass? thanks in advance for any advice. Frank

[@khaledzaitoun7321]

Good

[@averagemale2000]

Could of questions: What kind of gel coat did you use? Was there any catalyst used for the gel coat? What was the mix ratio? Was this epoxy or polyester resin? Why didn't you use PVA on the mold? How long did you let the gel coat dry before applying the fiber mesh? Rather than add music, why not just narrate the video?

[@tuning944]

Thanks

[@guidofernandez]

Why did you cut/rip the fiberglass mat into several pieces before laying it in and wetting it out? Doesn't a single piece wrapped around make the part stronger than 2 individual pieces overlapped at the middle?

[@ashishhinge6079]

Hey man Great Video, can you tell me the names and brands of all the chemicals and fiber glass sheet. Once again gr8 video
