This is exactly the info I've been looking for...thank you, thank you, thank you...especially considering I need to build a new boat recovery platform. My two previous platforms were built using PVC tubing & caps, and "pool noodle", to which the platform was 'pushed' by another boat...but, this time, I'm going in a different direction, basing the platform on RC seaplane floats. Unfortunately, while I thought the floats were plastic, it turns out they are Styrofoam. As such, to increase strength, I'll need to glass them...something I've never done before, and could use all the help & info i can get, starting with what resin to use. I've tried researching, but have come up with "conflicting" information. This 'conflict' has to do with whether, or not, certain resins will dissolve the Styrofoam. I have four questions, two about resin, and two about the fiberglass. First, the only two resins I'm aware of are epoxy & polyester. Besides these two, are there other resin types that can be used with fiberglass? And, of the various types of resin, which can safely be applied into Styrofoam, without causing the foam to dissolve? As for the fiberglass, I will say this - once glassed, while being lightweight is important, I'm thinking strength might be slightly more important, as the platform will be 'pushing' another, larger & heavier, boat, and because the floats will probably 'hit' boats behind rescued (especially the tips of the floats). So, would it be better to use a single layer of 'heavier' weave...or is it better to have two layers of 'lighter' weave, with the second layer rotated 90-degrees to the first? Whichever it is, I'm guessing applying an additional layer at the tips of the floats is probably a smart idea. Also, for each possibility (single & double layer), what weight cloth would be best? Again, I've never worked with fiberglass, thus I tell have no idea of what I'm about to get myself into. "Bonus" question - As I'd prefer not having to paint the floats, what's the best way of adding color to the resin? I haven't decided on a color...but, being that this is for rescue, I'm leaning towards yellow, red, or orange. Any info/assistance you can provide would be GREATLY appreciated.
Hi, laminating epoxy will work fine with Styrofoam. It will not dissolve, I've tried it several times myself. I recommend laminating epoxy with a processing time of at least 40 minutes. 1 layer or 2 layers; if you have a surface with tight radius or edges, definitely use 2 layers. A thick layer will not work on a very curved surface. If you got a smooth transitioning surface, you could use 1 thick layer. Hope this helps 😎✌️
Great Video DJ..Ive been wanting to tackle some carbon fibre work and I guess same principles apply? Have you got a link to the cloth cutter you use?? Yes love the format and the pull throughs at bottom are perfect to accompany the video. Relaxing music for a sometimes stressful job🤣Much appreciated!👍🏻
Thanks for the feedback Marx! This is the rotary cutter I use: www.amazon.com/Stanley-STHT0-10194-Rotary-Cutter-Yellow/dp/B009XAKK8K/ref=mp_s_a_1_1?crid=29CHZS1KV8IBK&keywords=STHT0-10194&qid=1700205902&sprefix=stht0-10194%2Caps%2C160&sr=8-1 Carbon fiber basically works the same, with same resin amount etc. 1 advice I didn't tackle in the video: if you have a plain surface / smooth curvature, you best use plain weave. If your surface has a lot of curvature, better use twill weave, as it adapts better to changing curves (e.g I used twill weave for my F1 cowl). That applies for cf and glass 👍
Sorry, I hadn't finished watching. but applying the resin as well as finishing? Also, what is the cloth weight, please? Also, only one layer? Thanks -- from Ian
Yes, you could apply the resin as a finishing coat. I actually never tried that. I prefer a clear laquer from a spray can. It's easier to build a nice and even layer with a clear laquer, I think.
Hi Deepu, yes it is, because it is based on the weight of the weave. It is not a scientific number, but you always need more epoxy, as epoxy will remain left in the cup, brush and roller. With 125% epoxy, you will have a bit more than strictly needed, so you will not come short. ✌️ DJ
It's both important. Impacts from a crash come from the outside and inside. Hitting the water stresses the hull plating, and from the inside, your hardware (lipo) creates a massive impact force to the hull as well! Therefore, I Reinforce my fast wooden boats from inside and outside.
Hi, it's actually glass weave, instead of fiberglass. The difference is that a weave has a structured pattern, with long glass strands, while a fiberglass mat is a collection of random direction short strands. A weave I stronger.
For a catamaran, you need more small pieces of fiberglass, because it has more separate surfaces. Please see this video of my F1 Tunnel, which is similar to a catamaran. It contains detail photos of the glass weave too: ruclips.net/video/VLsoFOm5FEo/видео.html
Hi, it's called glass cloth or glass weave. You can get it as plain weave, which is suitable for flat surfaces. Or twill weave, for curved/bended surfaces. Good luck! ✌️
This video contains more details on one subject, with extended cuts and new relaxing tunes. Let me know how you like this format! ✌️ DJ
Exactly like this, great job DJ
Thanks Daiciu! 👍

good detail, and teaching here -- thanks. Just wondering if a roller could be used instead of a brush??
Yeah you can but sometimes when rolling over the mat it picks up the fibres kinda of tearing your fresh mat
When assembling the hull of the boat, you put on a piece of paper and applied it. What is that?
In this video, I apply a glass weave. The purpose is to reinforce / strengthen the boat 👍

Carbon fiber basically works the same, with same resin amount etc.

hi DJ .. the number 1.25 is same for every gsm of cloth ?

Very nice work 😊your one of the best boat maker 👍done subscribes
Thank you Pinoy! I appreciate it 😎
The exterior of a hull is not where most of the problems arise... it's the interior of a hull- with bulkheads, etc..!
It's both important. Impacts from a crash come from the outside and inside. Hitting the water stresses the hull plating, and from the inside, your hardware (lipo) creates a massive impact force to the hull as well!
Therefore, I Reinforce my fast wooden boats from inside and outside.
Sand then apply more epoxy? Repeat of needed?
Epoxy itself doesn't add strength and is quite difficult to sand. For a paint prep finish, better use a lightweigt filler.
@@CozyRC I do plan to paint, what fuller to you recommend?
@jimfuller3712 I use a 2k polyester filler, from a local Dutch shop

Thanks for watching!
This is fiberglass, right?
Hi, it's actually glass weave, instead of fiberglass. The difference is that a weave has a structured pattern, with long glass strands, while a fiberglass mat is a collection of random direction short strands. A weave I stronger.
How do i apply this on a catamaran?
For a catamaran, you need more small pieces of fiberglass, because it has more separate surfaces. Please see this video of my F1 Tunnel, which is similar to a catamaran. It contains detail photos of the glass weave too: ruclips.net/video/VLsoFOm5FEo/видео.html
@@CozyRC Thanks. Can i use the mat if it is any more convenient?
@05_caoquangbach21 yes you could, but it will be more messy / harder to get a nice smooth result
What is the name of this Viber? Can you write me the name because I would like to buy it?
Hi, it's called glass cloth or glass weave. You can get it as plain weave, which is suitable for flat surfaces. Or twill weave, for curved/bended surfaces. Good luck! ✌️
@@CozyRC Can you send me pictures of the woven fabric?
@@yasermohmmmed3873 It's shown in the video! 😎
@@CozyRC Yes, watch the video, but I am from Egypt and I want to get it from China. For this reason, I want its name
@yasermohmmmed3873 allright, please send me an email at cozyrc1@gmail.com 👍
Excellent word 👍👍👍i will subscribe you Bro
Thank you, I appreciate it! ✌️
