Yea I did, was just wondering if the volume changes based on size
So…66 grams per coat? Read the label and I would have to add two cups of epoxy and one for hardener, just need to make it add up to 66 for each coat, using the roarockit vacuum bag for it
I’d say weigh your fabric (or calculate the weight by multiplying the g/m^2 and the dimensions (and the number of layers)), and then go for a little more than that amount of resin. If your fabric is 110g total, for example, then 110+g of resin should do.

Alright I’ll do that when the fiber comes in. Appreciate it, got any tips for doing it the first time and that everything goes right?
Watch some videos on YouTube of people doing this. Easy composites have heaps. Or read some tutorials.
That should give you a good idea of process to follow.
I would weigh the epoxy or use an accurate measuring device to get the correct ratios. This is important. Don’t freestyle the amounts

Take time to lay-out and prep your tools and workspace, and maybe do a bit of a dry run before you release the schmoo for real, to hopefully avoid the “Oh shit, I need this thing but I didn’t get it before I started!” effect.
Gloves are a great idea. Doubling up can be a good strategy, so if you get your hand(s) all sticky, and need to pick up something and not get it sticky, you can just shed the outer gloves and still have gloves on.
Definitely lay out a good sized dropcloth/newspaper/something to keep resin off of all the places it shouldn’t be.

That’s the one thing I don’t wanna fuck up on. Adding the same ratio, three times. Once I get that done. I’ll feel accomplished, I need to clear the carbon fiber once it’s out of the vacuum bag right or I leave it as is. Didn’t see anything like that in the videos I watched with the vacuum process
A clearcoat afterwards is usually done, but it’s mostly cosmetic. The composite itself is already as strong as it’s gonna get at that point. The clear fills in the roughness left by the peel ply.

The gloves is a good idea, I’m gonna have to look up if you can do epoxy outside or since it’s starting to get cold out, if I can do it in those kind of temperatures. I got a heater temporarily in my garage so if the fiber comes soon, I can start it right away and just do it in the garage with the door open, ventilation
White vinegar washes off epoxy resin, and is a bit cheaper and easier on the skin than acetone if you get resin everywhere
Painters touch might work
Inside. Temperature control is very important

Most epoxies don’t like to cure below about 10-12 degrees C, and cure much slower at reduced temperatures. A general rule of thumb is that every 10 degrees C of difference doubles or halves the reaction speed. Keeping everything near room temp is a good idea.
Doesn’t it stink tho. Only reason I said garage or outside is because I don’t want the house smelling like- whatever epoxy smells like
Why three times? Huh? I’m getting a bit lost with that. Won’t you just mix a batch, brush on board, layup the fabric and brush out epoxy between / spread out and do all fabric layers one after the other. Peel ply. Bleeder stack. In bag. Vacuum. Check leaks. Drink more beer.

Ehh, epoxy doesn’t stink that much. Vinyl or polyester resins are very stinky, but most epoxies are much more tame. Plus, you’re vacuum bagging - it’s gonna be sealed up!

Don’t you add base coat on the board first, coat on top of the first fabric so the second one can go on and lastly a coat on top of the second or that gets left alone?
Shit, someone needs to make an instruction thread (or two) for this

Not sure what the Raka epoxy is. Another thing I need to find out. And what temperature it’s best for it. Guess it’s a research typa night
