How To Fiberglass - Two Part Mold Layup - Sub Box

[dubhippy]

cool video. it worked about the way i imagined, but i'm trying to think how i'd be able to use the same technique making a custom stereo boombox with just 8 inch woofers. it would be pretty hard getting inside a box through maybe a 7 inch opening on each side. maybe i could do it if used smaller tools. i was originally thinking of using 3D printing, but that's very expensive.

i DID learn that you lay up your 2 halves separate before joining though.

[jonisd]

i want to make a engine cover for a boxster out of fiberglass , how does it hold up to heat and such things , wear n tear ...... also is the cost of materials for such a part.

[jonisd]

@jonisd what is the cost **



[pastlearner]

How many times the mold can be use?

[sazza5865]

Nice video :). I work with fiberglass n I'm gonna make a mold for my subs when I can

[xxscreamxthenxfirexx]

do you think you could possible make a sub box for a scion tc?

[extantia]

Thanks for the heads up about using talc to prevent fiberglass itch. Before I used paper arm sleeves and gloves which get very hot in the Texas gulf coast climate where I keep my boat.

[extantia]

Love your vids!! I'm doing a fiberglass refinishing project on a sailboat (learning as I go). At what do point do you prefer to use PVA, and at what point do you prefer to use mold release paste and why? Do you ever use peel ply?

[GasserGlass]

BEEN FIBERGLASSING 35 Plus Years... You NEWBIES Pay Attention... Its very rare for a novice to post a correct HOW TO VIDEO.... This young man is showing you absolutely the correct way!!! Your getting a year of lessens for free by watching this video! ........ Fiber-glassing takes a certain amount of natural talent too...watch his hands... His hands work like hes a musician playing a piano!....GREAT JOB PUNK!

[averagemale2000]

mute

[greenlice93]

how do you make the mold?

[Quekil830]

Gloves could help out too

[spunkysandoval]

very impress



[fonzorallie]

can you make a fibreglass plug out of polystyrene? or will the resin melt it

[bluefox4848]

What would I do if I have a 2-part mold without a way to go inside and glass the seam?

[shirleymae30]

Why go thru all this work for speaker boxes ???, let alone ones that are going to be carpeted over ???. Couldn't you have just used a core, form, or male mold and not really worry about getting such a smooth finish ???. Also... do you think that metal screen material (common alum, SS, or bronze) could possibly be used as both a form and as a core for fiberglass projects ???. cool video, thanks.

[bub1360]

how do i get the air space?

[xcalibercustoms]

very nice work!!! check out more fiberglass tutorials on my channel!!!

[chewbacca0301]

i was wondering were you got the 2 part mold from

[djscootersmooth]

good job, i made a fg box for my car. i went the cloth route tho. it came out good, its been bangin for about 3 years =)

[gccruz11]

Great Job on the vid, Used it this last summer to produce a set of Spats for my car. It's a newer model and not much for it. I sent them to a company in Taiwan to have an order produced in Carbon fiber. Have you tried working with Carbon fiber yet?

[r6ridah360]

how did you go about making the mold I want to do this in my SRT 4 as a project to pass the time and customize the audio im gonna be doing thanks man

[sphinxtk]

Just another comment to add to the one I made a while ago. I've been doing the same thing over in the UK; making the custom plug, making a mould from that (ended up being a 3 part mould) and then making the finished boxes. Having tried 'my own' way on a few things I've always ended up re-watching these videos and going 'ok, yeah that's a better way of doing it' so again, hats off to you fella!

[mishai26]

U should wear gloves for safety..nice work due.. cool..learn a lot.

[joe27baja]

@mishai26 you dont wear gloves around rotating equipment = not safe. He should most deff have put on a mask though

[timithy1]

lol i like the car test

[sphinxtk]

Hi Punk

You've really made some fantastic videos! very informative!

I've got a couple of questions if you don't mind; what type of resin do you use? epoxy or polyester? and also, for your moulds did you use normal gelcoat or 'tooling' gelcoat?

Thanks

[BakedAndExpressed]

thats pritty sick dude

[onlywhenpissed]

Nice work, but.... I wouldn't have taken the glass up to the tops of the moulds in the first hits. I'd also have used a bit of clay (plasticine or wax) when the two moulds were clamped up, this would mean less trimming and less dust. But it was your job and not mine so hey ho! Fibrelass is an awesome material to wotk with it. I use it on a bigger scale than small mouldings like this though. People really dont realise how much time it takes even to master these skill. Years!

[RambleFest09]

Holy crap, is it just me or were you not wearing a breathing mask? D:

[robotmotor]

make another video about fiberglass microsheres and how it help to fill the sharp bend and small gap and tech us how to apply it

[djmhykl]

what a great video

it helped me with my project

tnx bro



[jaidevcool]

Boss, the best hands on video i have seen. Very good work!!! Keep it up.

Post some videos on LRTM molds if possible.

[dfb2009]

LOVE the video, if i was you id crank those babies out and ebay them or something lol. i do alot of fiberglass work too, im making a custom setup for my sisters 07 Charger trunk with dual 10"s right now. just curious...your resin seems about as viscous as water...how? what kind of resin are you using? ive tried a ton of different kinds and they are all about the consistancy of maple syrup :/...id love to know what kind of resin, make my life ALOT easier. thanks alot man! thumbs up!!!

[kalaiisgood]

Wht is tht 4 Inch grinder exactly called? I knw its an angle grinder machine but please give me the exact name of tht Grinder attachment...

[AlexandruBogdan81]

good video .. i was lookin how to make a carbon fiber gearbox ... didnt know how to work whit the resins mold wax etc :) this video helps!!!

GJ bye

[william2240]

I want to rebuild my concession trailer that burned down. I have the frame that is metal and want to make fiberglass walls for it. What way would you recommend to make the walls and how thick. I will also put windows in it. We are going to make this a project with a local high school. Any creative ideas would be appreciated.

[robbiexps]

obvesly dont breath that shot in when u are grinding it. i bet u regreted doing one of those layers without a glove lol

[Timulch1]

I have a mold about the same size. How much chopped mat f/g did you use?

[punk28186]

@Timulch1 For the mold? I didnt use much, I like to keep the mold wall thin so it has allot of flex. If you talking about the part, it depends on the application.

[1974UTuber]

Nice handywork but its a seriously ugly shape. It looks awful lol. Sorry I love your work but not the shape of it.

[jesinu]

What's wrong with the shape of it? Didn't you see the pic at 8:18? It is made that way so it will fit nicely into the corner of the trunk. It's not like it will be sitting in the middle of a living room.

[1974UTuber]

@jesinu Yes I see that now and it fits nicely but on its own it looks like a butt.

[NcHalfrican]

Nice work, bruh!

extra props for using incubus :D

[jonwhunt]

How many layers of fiberglass did you use to make it that strong?

[punk28186]

@jonwhunt 'layers' is not a very good way of describing strength because there are hundreds of thicknesses available and hundreds of types. The one at the end of the vid with about 8mm wall thickness average. Its the sphereical shape of the box that multiplies its strength, it could handle many time that much.

[jonwhunt]

How many layers of fiberglass did you use?

[Zetune79]

Great video by the way. I am surprised at how far you would go to produce such a specialised item though. You're set up to make dozens of these now.

[punk28186]

@Zetune79 yeah Ive made many. It saved allot of time.

[boober2008]

hey man, how could i make the mold off the car? spare tire space thxz

[punk28186]

@boober2008 I suggest you join a fiberglass help group, with a forum to get that answered accurately. You talking about a different type of mold then what im showing in these videos.

[TheMedievalMan]

I hope you didnt grind without mask and eye protection. Those glass fibers are dangerous to inhale and for your eyes.

[TheGDizzo]

Ugh... Wax on the tape huh. Oh well... I know for next time now. After I masked, then laid Aluminum foil... I used a lil more masking tape inside the Aluminum foil where I wanted to make sure that certain spots where sealed-up to prevent Resin from being able to go thru. It worked for that purpose, but jus' a lil difficult to pull everything off of the initial hardened mold now. :S For a small project like mine, Which kinda Wax, where to commonly get it?

[punk28186]

Carnuba wax is the proper stuff, but even a bit of kitchen oil or vaseline will do the job.

[stratzombie]

How do you decide when to use fiberglass mat vs. fiberglass cloth?

[krisweller]

By the molds i meant the part that is molded to the contour of the space they are fitting in... How did u make those ? Pack your car full of clay to get the impretion ?

[punk28186]

in a nutshell, over mask your boot area and get the backing molded piece, reinforce it and finish the front. with rings and fleece.

[punk28186]

a bit of wax on the tape, and fiberglassing a few layers will get the shape, then remove and reinforce it etc

[krisweller]

how do u make the molds for these boxes.

[ilogikmr2]

Why do you use the talk?

[bonelesscandy]

i wanna see a step by step on how to fiberglass a whole door pannel, i wanna do my 2 door 94 integra but have never done any fiberglassing before. i dont wanna add any extra skeepeks or anything, basically a stock fiberglass then painted door, if u could make a video like that it'd b a big help, nobody has one on youtube yet, ive looked. sweet video, thanks!

[mistasage]

Should really wear a mask bro

[doyleaudio]

That's impressive work.

And after 30 years in the business, I would know. LOL

Cheers.

[punk28186]

thanks xD

[punkrockartshow]

Awesome tutorial! That is really freaking strong! Could you poor concrete into the mold? Thanks!

[punk28186]

yes had a friend who made fiberglass moulds of stone sculptures and cast them with different concrete mixes that imitate stone. Would be no where near as strong.

[punk28186]

allot

[sidlemar]

what type of resin did u get..where did u get it from...and does it dry clear

[punk28186]

Im in Australia, got from FGI, polyester resin. Polyester doesn't cure clear, you will need to go epoxy or vinyl ester.

[dan0dank3]

very nice,man.........good tutorial

[tukyo]

whats the name of soundtrack

[punk28186]

The Whitlams - Louis Burdett is the first one.

[05560421]

Sweet vid man!! cheers for the help :-)

[00Mandingo00]

nice video. What does the talc on the hands do while you're grinding? Protect your hands from fibers?

[punk28186]

clogs your skin pores before the fiberglass can. talc is non toxic, fiberglass particles are not.

[00Mandingo00]

ahhhh i see! thanks for the tip :)

[CrazyCraig0516]

Great video! everyone else skips the mat layering part.

[fals3illusion]

what kind of resin did you use? im guessing polyester w the MEKP hardner?

[punk28186]

Yes. Unwaxed or 'layup' polyester resin. I buy wax additive and only ad it when I need it.

[NAPALMJUNKY]

great vid punk28186, i was just wondering if you do all your layering continuously or do you do say 3 layers let it dry and then do another 3. cheers mate!

[punk28186]

hmmm i wonder who this is xD... IF you are using UNWAXED polyester resin then you can wait as long as you want between layers of fiberglass without doing anything in between. If you are using just the std waxed resins then you need to either layup your layers while the previous layer is still geling up or you need to sand away the wax that forms at the surface before your next layer. If the previous layer is still tacky its good to go. Layers will come apart over time if you dont follow this.

[punk28186]

sorry thought you were a friend.

[NAPALMJUNKY]

no worries. Thanks again for the info!

[steraeris]

d@# gooooooddddddd ending

[vallesan]

great. cheers...

[sardosfish]

great.thank you for posting

[red666A]

What kind of wax are you using there? Will that be able to help remove the tape away from the mould I'm making in the trunk. I use W d 40 but that did help removing the tape away.

[punk28186]

any release wax is good to coat tape when doing boot molds so you can easily peel the tape after the cure.

[AliGhanizad]

watchin only one or two parts arent enuf for me. I m goin to watch all d vids of your channe nw and subscribe. Cheers man

[punk28186]

No probs mate,

[AliGhanizad]

SUPER AWESOME VID, that day i saw street customs and wondered if i could make my own molds. And fuk that is really strong.

[red666A]

How many fiberglass mat did you lay on that and how much resin did you use to do all that? I'm making a mold and I'm only lay down 5 layer so far. I was hoping it would be strong enough because this sutff is costing me alots of money.

[punk28186]

It really depends on how thick your layers are, they come in a huge selection of weights(thicknesses). I put about a dozen 600g layers on these, but thats over the top, the smaller you make the walls the more tinier the sound is. 5 layers should be fine.

[boober2008]

thanks alot man will be waiting with finger crossed lol. u r great.

[boober2008]

hey. how did you build the moulding from the trunk of your car before using the fiber flass?please and thanks for the awsome videos

[punk28186]

This video doesnt vocus on that part at all. But I put up one of boot moulding soon.

[ChuckWag78]

Hey, great vid! Very helpful!

What is the name of the song that is playing in the begining?

[punk28186]

Thanks.

The Whitlams - You Sound Like Louis Burdett

[mxracer6969]

how long did this take?

[punk28186]

i really cant remember, maybe 20 hours for the mould only? The mould were not perfect as these are all finished carpeted. You can spend hundreds of hours easily on a mould to get it right.

[josh94HUFC]

ive gt a metal go kart seat and want to make a fibreglass version by coating the back of the seat then pulling it fr the existing seat wud this wrk

[punk28186]

Yes. I would still flange around the outsides and fill in any holes. Release agents and lay it up. Dont need gelcoat if you dont want.

[Stahlherz]

wow, good job oo

[amppower]

HARD BOX HAHA WONDERFULL

[punk28186]

Never heard of davids fastglass resin, it probably is polyester resin anyway. If its a resin use it.

[5006944]

thanks bro

[punk28186]

polyester resin (wax free)

[dantiri]

Nice video man! To cut the fiberglass I use a bosch pmf 180, with a tile-cutting blade. this is an excellent tool because it vibrates instead of rotating, so glass dust does not go everywhere.

[oilfield666]

same type of tool they use in hospitals to cut off fiberglass casts

[mysubsbang]

i also thought of rino line it then wood top it lol. hmmmmm what to do

[maphound]

Do you know if fiberglass is an acceptable material to use for making a storage tank for alcohol? I would like to build a fermenter for making beer.

[punk28186]

Not 100% but yes it should, as long as you coat and seal the inside with a 2pak paint or gelcoat/flowcoat. Actually im making an alcohol fuel tank for a car fuel conversion and I wouldnt mind knowing the long range effects of it too.

[mysubsbang]

how about making the inside of the spare tire deal in the trunk of my car into a speaker box? single 15 inch sub

[punk28186]

This is about molding and not about the original sub box.

[oilfield666]

wouldnt be hard....use the bowl for the spare tire as a mold then wood top or layer fiberglass on some wood to make a top plater

[punk28186]

where would you put the tire? You always have to consider practicality.

[oilfield666]

the same place my spare tire is sitting for my f150...in my garage....when i do go on long trips (900km run to visit family) i dont even pack a spare

[mysubsbang]

thats what i was thinking cause it wouls sound realy stupid im sure with just the wood top and metal all around lol.

[raybinns]

It's ok if you make sure you use a chemical resistant resin there are resistance tables on the scott bader website for all the different types of resin..

[xenepp]

Love your videos man, they are the most informative I've seen. Awesome craftsmanship!

[akoett]

Nice video man

[getoffmyinternet]

Others might be interested to know that they also sell grinders (air grinders usually) with adapters for a shop vac, really helps with all the itchy dust. I'm sure they even have vac adapters for regular grinders as well.

[JustWonderingHowToDo]

Great video. But I still haveq question:

How strong is that gellcoat on the inside of the actual molds, how many parts can you make before it shows wear.

[mussimike]

Thanks for this vid, concise, informative and I even liked the camera fall.

[scraprdy]

yo nice vid seriously, thanks for the talc tip, ima need that since im starting a project of my own, 2 12' fiberglass box, i didnt think i was gunna need so much fiberglasss, that i have i just ran out of resin, thanks for the vid nice job

[VE3n0m]

Sweet job dude :)

Looking to mold my own hard-top in fiberglass to my car since i only got a soft-top today.

Might get around molding my own speakerbox later on as well. Great video showing off a mold teqnique i haven't seeb before really :) Cheers mate.

[KabeTKD]

i like the car on it at the end very cool and not flexing just set it off lol nice job wouldnt mind being able to do that lol

[modificatos]

Excellent video, like the way you speeded it up, and nice tip about the talc on your hands.

[intheshitter]

omg this is amazing thanks for these vids :)

[sharps5]

hey this is rely gd im looking to do the same thing as i want to build my sub into my wheel arch to get it out of then way would it be possible to do the same thing with a gelcoat as i dont want to carpet mine ? cheers

[comrade904]

LOL @ OFFICE SPACE!!!

[nbm34]

AWSOME one amazing guy. Amazing well presented vids showing a skilled man at work. BRAVO

[punk28186]

thanks mate.

[greatscottbttfride]

were u get that fiber glass from

[PabloAwera]

How many coats of FG mat did you aplied? What's the weight per square metre of FG used in the video?

Thanks

[punk28186]

I use 225g and 450g in this video, about 2 layers of 225 and 4 of 450.

[4jiggy1]

were to buy moldes?

[ryangthaboss]

bad ass build keep it up man

[jesinu]

I found these very useful. Great job! The mits on the sub enclosure was impressive. What is the talc on the hands for? And where is your respirator man?!

[punk28186]

I had an extraction fan blowing fumes out and it was a windy day, but I usually wear a respirator. Talc clogs your pores and doesn't allow any fiberglass dust in to make you itch. I mention it in another video.

[ohnedich42]

thanks, I didn't know that, great job!

[canemaster7]

Hey this is awesome work and I want to do this but where do you get the mold in the first place?!

I see that the final product fit snuggly in the trunk but where/or how did you make that original mold for the sub box?

Thanks

[punk28186]

That is to much info to type in a msg. I am going to do a sub box video some time. Subscribe and wait.

[jcteodoro]

Nice video very informative. Great job!

[csmoke303]

right on for the video. this video is the shit!. i gotta sit down and watch them all so i can take notes on them now!!! you know your shit bro!!

[punk28186]

Thanks bro, I see you do allot of custom car audio. This way you can reproduce one of your good enclosures for production. Any questions pm me eh.

[littlefireryone]

F*%k yeah BIgs! I gotta get you to do me some stuff sooner of later

[punk28186]

Hey Aidan, something on the datto I imagin?

[littlefireryone]

Yeah was thinking about a front stone tray with a lil' spoiler incorporated into it. Trying to chase up a repo panel first though

[punk28186]

Sounds good.

[fogfish666]

very nice work

[punk28186]

Thanks mate.
