I’m looking really hard at the photos and I’m 100% certain if you get all that fabric off the flanges and keep the carbon strictly in the bowls infusion #2 is pay dirt.
Well call this chasing the glory bowls just like glory hole from Alaska gold rush only difference your after two of em.!!! 
dallas, unfortunately i am out of cloth… , so im kind of dead in the water at the moment. so i will have to place an order and give it another go next weekend. so right now i have the time…not the material…
i agree…so do i use a template for the cloth? then cut the carbon to the exact demensions?
Spray tack the fabric in there. Then trim the excess with a pair of sharp shears.
Save the scraps.
Oh and here’s the cutting tool you need. http://www.harborfreight.com/5-piece-diamond-mini-cutting-discs-31501.html
Then final trim with 120- 180 grit sand paper.

To fix the voids mix up a small batch of resin and brush it into the voids. Fill it deep and tape a strip of bagging film to keep the shape and hold the resin in place. When it hardens the bagging film will rip off an you can sand it smooth.
Do the same with a clear 5 minute epoxy. The film helps make the repair a bit more manageable. Sorta think of it as a band aid. You can also work it with your fingers to keep the resin in place.
Sand them puppies to 600 grit and shoot with a clear coat and you’ll have some nice looking parts.
hey dallas, one more hour of cooking for the rain hats…i have them in my powder coating oven. which is just an old electric residential oven…
i just ordered some more carbon. OUCH!!! 240 bucks.

my cut and paste didnt work out so well…
for next weekend i got
1 yard light blue carbon/fiberglass 79.00:eek: (matches the porsche better i hope)(and hopefully it will be easier to cut than carbon/kevlar)
5 yards of 3k twill carbon 142.00
and a leak detector
i am super deep into this now. i need to make some show pieces;)
oven curing kinda sucks. do they make a room temp curing infusion epoxy resin?
Hey Doug… You gotta take the end off the stethoscope and put a piece of tubing in it as a probe… Those leak detectors… Waste of money. IMO.
Am I reading that right you only got blue??? Why not put plain weave under the blue to save money.?
Just curious. 3k twill is expensive to do 2 layers on a cosmetic part. Plain weave under twill is plenty strong.
Just suggestions. Oh and plain weave is like half the price of twill. So if you were to order the plain you’ll get twice as much yardage for the colored fibers.
thank you for the tip.
your right the carbon really wont even be seen. will the plain weave be just as plyable? the website said the twill is more pliable than the plain.
i could always order 2or 3 yards of the plain and save the twill for the cosmetic layer on other projects.
leaks suck…i would have paid 5 hundred bucks for something after 3 hours last night:mad:…if the detector dosnt work i’ll sell it on ebay.
am i looking at this right? it looks like the 3k plain and the 3k twill are the same price. http://www.solarcomposites.com/composites/compositecarbon.html
cuz im a rookie making dumbass mistakes. expensive mistakes…
Yea your looking at it right.
1k plain is a bit overpriced @21bux a yard.
You wouldn’t know the difference till one of us told you…they were mistakes. Don’t get frustrated Doug your taking alot in on this project.
Hopefully for your sake you can sell some carb hats. The show pieces is no problem at this point. The first pull proved it.
your right…and i am truly gratefull for you and rotos help and input. i wouldnt even be close without you guys…
now i a good note…i just took the hats out of the oven… OMG:eek: IM STOKED…now they sound like glass when i flick them.
IM GONNA NEED A BIGGER OVEN!!!:D:D:D:D
No. When you do the infusion next time you’ll be making separate hats. Not two connected by tons of excess fabric. Then they can fit in the oven individually. 
i got a tube of caulking dallas. and about 5 hours till i have to leave. you said you were gonna show me how to make some caul plates with the caluling?
Yeah you got silicone right??? acrylic might work but would take days to dry and I think it would be too hard. Unreinforced silicone is pretty flexible.
Mask off 2" above and 1" below your bottom radius in your bowl. Might have to clean with alcohol to get the tape to stick. Then apply some frekote with a cotton ball and let dry.
Get a acid brush or china brush handy. Cut 80% of the tip off the caulk tube and squirt into the radius then dip the brush in water and smooth the bead you squirted. Silicone dries quick. And released pretty easily. Try to get a straight angle of a fillet like a 45 fillet. When it drys peel the tape up and the silicone ring in one piece and trim the edges to the tape line. You’ll have a ring of silicone that fits tightly into the mold.
Cut a diagonal slit on the long side to allow to shrinkage and expansion.
You can use inside your infusion bag by releasing and wrapping in peel ply. Or use bare in a double bag.
This will force the fabric into the corner and with a double bag you can push with full vac during debulk and leak down check. Then kill vac in the second bag while it infuses to allow the resin to get into the corners and then hit it with full vac to press excess resin out thus pushing the fabric tighter.
General purpose silicone works in low to medium service temps. Try lighting it on fire an you’ll see what I mean. In the future you can also reinforce silicone with carbon to make a les flexible tool.
Simple use of silicone 101!
They sell silicone that vulcanizes in ovens but… It’s time consuming IMO. I like the quick turn around of rtv silicone.
You can even make rtv silicone (high temp) coupler hoses now Doug!! Carbon reinforced at that!
Lol
Oh shyt Doug silicone and freekote are bad bad bad. Wax for silicone. Damn. I’m sorry dude!!!
