Some of these tips even I didn't know, and I work in a carbon fiber workshop for about a year now. The solution to pinholes for us usually is in the release agent. Using PVA basically eliminates all pinholes outright, some waxes can also help with pinholes tremendously. The one we use from R&G is almost liquid and ensures a no pinhole finish, but usually leaves alot of residue that needs to be wetsanded off with 800 grit. Keeping the carbon from fraying and the weave alligned is an artform unfortunatly. Don't beat yourself up if it doesn't work too well for the first attemps, it takes time and skill to do properly. A recomendation from my end is to use prespraced Carbon for these. HP Textiles has a set of carbon weave that is just very lightly sprayed with adhesives, making it stiff enough to move around without weave distortion, but a light pull along the fiber breaks these bonds and let's you shift and shear the weave in the mould. This makes it an awesome material to work on complex parts that need to have a nice surface finish. A more advanced tip I have for all of you that work with vacuum bagged parts, is to degas your resin after mixing. Get a vaccum bell and put the cup in it for 5 minutes after proper mixing. if removes most bubbles you introduced and helps you to avoid roling those into your parts later on. It's not neccessary, but it saves you the venting roller. Especially useful for tight radius parts where the vent roller is beyond annoyning to use.

Loving the extra tips. This video got a nice little forum to help many with all the different tips being given now lol. 🙌🏽.

[@michaelc2321]

What type of carbon fiber work does your workshop do mostly?

[@ajhartmanaero]

All good tips guys. Pinholes are the breaking point for a lot of people getting started in composites for sure.

[@StreetBandito]

glad to get some affirmation that we aren’t the only ones with that issue lol. The Pesky Pinholes never fail.

[@adamnonis7022]

I know I’m a long ways down the list here, but just a note from my composites experience. Some resins (and gel coats) are unwaxed and meant to stay tacky between layers. Lay-up resin in particular and most gel coats are anaerobic and fully cure in the absence of air. The trick I use is to spray a few layers of PVA over the top. The PVA will seal out the air and let it fully cure. This really works good if you want to add a layer of gel coat to the outside of a part once it’s done. I make stuff from carbon without a mold from time to time, then spray/brush clear gel coat on the outside and coat with PVA. After curing you can peel/blow off the PVA and you’ll have a hard surface to sand.

Hi, good video to explain 5 common mistakes. I'm work in composite industrie and i make plate with fiber/rigide foam/fiber and all that in vaccum infusion. I work in france and i follow about 3 years. Just i would like say one fact, i do one vaccum infusion with this specifcation: mold temp 16°C; resin temp 17°C ; room temp 18°C and 50% humidity. I does made plate but i do put 2.75% of hardener (normaly 2%). Finaly the plate are good just the gel point is morreless long. Ps: sorry for my english Have good day

What always works for me with #1 and #2, is denatured alcohol. Mix about 5%-10% in, after mixing your 2 part. This slightly dilutes the epoxy and makes it flow/absorb easier. It’s also hygroscopic, so I draws out the moisture and air bubbles. You will notice a slightly longer off time as the alcohol needs to evaporate

If your looking for a quick functional fix for something like that void, you can try filling it with baking soda and wicking in thin ca. Its super super strong. The soda works like a catalyst and it sets hard, quick. Just do it in layers if its deep.

[@MindDezign]

All handy solutions. I love powdered gloves from Sysco a food service supply company. Easy on easy off.my hands. I hate taking time to put them on,the prepowdered helps speed up this action.

[@amgonegaming9515]

For the slightly large holes I think we can use carbonfiber dust with few drops of resin on top and sand it later.✌️👍

Thanks team great videos, i'm about to try doing a VW beetle engine lid the old style very curvy any advise? Please. do you ship kits to New Zealand?

Awesome stuff. How about tips for trimming a part after it cures and removing a part from the mold.

[@StreetBandito]

Just send it lol. Nothing special that we do. Just use a cutoff wheel and a grinder. Also make sure to use a respirator because carbon dust is very bad for the lungs.

I never would've thought of that brush tip; these are awesome tips. Dumb question... does the super 77 make it difficult to remove from a waxed mold?

[@industrygaragedistribution5554]

All good no dumb questions. No, I've never had any trouble with it after the part cures.

[@derrickdennis6383]

Love it great info, I have been wanting to build a carbon fiber gas tank for a motorcycle project, what kinds of things do in need to consider when building a carbon fiber part that holds gas? Like what type of resin? Should I use a secondary epoxy liner on the inside after the tank is built? Can you lay metals like aluminum in between the layers of carbon so I can bolt on gas caps, and petcocks? Thanks allot guys love the channel you guys do awesome work

[@Captaindan7141]

You do NOT want aluminum touching carbon fiber, they covered galvanic corrosion in the S2000 video recently.

[@lmSteveo]

Do you have a video to join two ends together. Like a part that has a lot of shapes like a front lip or a diffuser?

[@DMAX_DIY]

Thanks my friend for posting this.. There is so much 'non' information on how to actually make carbon fiber parts.. I am making a structural frame for my motion rig and already bought all the fiberglast stuff to begin. Not worried about pin holes (cause this is my motion sim frame IDK) but really trying to get as much info before I start.. Thanks so much! DMAX motion sim ch

@@StreetBandito Well.. It's been helpful but I have not started it yet.. it's like 20-30 degrees in my garage.. I need to wait till spring I think when the temps are a little more stable I think the viscosity will be an issue right now.. DMAX

[@GreasyFingerboys]

Great video some great tips. I wish you would have explained how dangerous and easy it is to inhale glass micro balloons. Also some resins will react if you put good resin on top of bad resin as well you may condemn the resin underneath to never cure as it will not have a path to off gas volatiles. Best to sand into the resin breaking the gloss barrier and giving it the most surface area to gas out. Some heat helps too😀

[@StreetBandito]

Yea we missed that part about not breathing that stuff in lol, but glad people in the comments shared that important tip.

[@GregoryBrettin]

Have you thought about running small workshops to run people through making CF parts? It looks like you guys have a lot of space to set up in-personal instruction. You have Fibre Glast as a distribution company so I bet they would be willing to kick in something for future sales. That could generate additional revenue and video content. If you DO decide to do something like that, HMU!

[@industrygaragedistribution5554]

Great idea - thanks man!

[@NemrodhYarKemma]

PPE.. You can develop a allergic reaction to the fiber glass and carbon fiber. Seen it happen to a few guys when I was working with the stuff.

[@Vlady_e30]

Thanks for all your´s videos. I want to make BMW E30 bonnet from carbon fibre by wet lying.. Can you help me to choose how much material to use? I got 2 opinions: 3K 200g and 12K 600g carbon fibre cloth. So for bonnet can I use 1x 600g and 1x200g on top and 1x600g + 1x200g for inner bonnet part and glue both parts together? Together it will be 1600g/m2 of carbon fibre.

[@industrygaragedistribution5554]

If I'm understanding you, I would do it differently than you suggest to avoid making the parts too thin. I would use two layers of 3k with 1 layer of 12k on each of the top and inner parts or use four layers of 3k on each. After the components cure, use a compatible epoxy to combine the two parts. Let me know how it turns out.

I have chip in carbon panel (that looks like bigger shown void). Is it still viable to just pour resin inside of it, sand flat and clear coat over whole panel?

[@StreetBandito]

Yea you can try that out. Just make sure to sand the void a little so the epoxy can adhere to it.

Very great tips! I so want to try it.....just knowing me if i did and it works out i would not stop.....once you do a carbon fiber toilet you would know you have a problem 🤣

[@ajcates9136]

Do u make any c5 parts

[@StreetBandito]

Not at the moment

[@MrMuffanga]

Keep in mind carbon fiber causes galvanic corrosion! So it needs to be treated as if it's aluminum. Meaning it needs a dedicated area where it's not contaminating any metals

[@reichartsworkshop]

I need a garage heater for my next part attempt, I'd be lucky if it's 55 in there

[@StreetBandito]

We’ve made progression because lord knows our area used to be in the 50s back when we started lol.

[@zachcarrizales5038]

I think these are all great points, but I think you are not doing justice to the amount of time and attention necessary to how your total beginning setup relates to producing good parts even before you start mixing resin. Here are some of the easiest ones: Having a room/sectioned off with plastic that you just do carbon layup to minimize dust and particulates into the layup process. Never touch your carbon/glass fiber fabric that you are going to use for layup without gloves - your hand has oils and can transfer to fiber. Another tip, have a wet layup table that is kept clean and a separate cut table, or you run into the issue of dry fiber snags or weave distortions. Also not sure I agree with bristle brushes to apply resin because of the increased friction during layup. And lastly, maybe this seems obvious but people unfamiliar to composites might not know - Do the volumetric density calculations before you start mixing so that you only use what you need.
