does anyone know for sure if it can be cast into a mold and then demolded and used for a core (mandrel)
"Aquacore™ comes pre-mixed and can be packed, either by hand or hydraulic pressed into the desired geometry. "
sounds like it to me… may not be quite as easy as just pouring it in
Problems,
What type of silicon is used to make the Manderal bladders and where can it be purchased? Is it simply brushed on? I am guessing it is also somewhat spongy to be able to b pumped up to press against the CF sleeves onto the mold.
Aquacore seems really cool. It souns like it has many uses as well. using that would eliminate the need for the manderal bladder as you could make the mold and pour it into the mold to foam the need pipe than slide the sleeve onto the aquacore mold and make the pipe. I am guessing it would then need to be vac bagged? The only problem would be it may get expensive compared to the manderal bladder as far as mutliple pieces are concerned.
You’ll be way ahead to have a pro like Bondline to make it for you. www.bondlineproducts.com
Tell Cosby “JM” from GGROP sent ya…
that is where he got them I believe is from bondline
for the mandrel, you can also use a bicyle tube and cut the tubee near the valve stem. fold the ends over to clamp them and fill the tube with a tire chuck.
Its simple crude and “cheap”
Man that sounds almost too easy 
I am sure it works well though as tire tubes would contour to just about any bend. I wonder though, what if the mold is longer than the tub. Can 2 tire tubes be joined together?
if you have a 24 inch tire, that means the diameter times 3.14 equals 75 inches. What in the engine compartment is longer than 75 inches?
You can cut a short section and put a pvc pipe into the two ends you want to join, and then slide the short section over the joint and apply tire patch cement.
what kind of diameter can you achieve with the tire tube?
depends what size tubes you get, at out local bike outlet they have them as big as 5 inchs in diameter
…or a car tire shop…ougie’s condom size? :roll:
Thanks Jim… Were you peeking again?
Seriously if you have ever blown up a innertube ouside of the tire and rim, it will expand much larger than you need.
I have had the tube outside the mold expand beyond the edge of the tool. I will also say you don’t need much pressure to press the sides out. i never put too much pressure into the tube. I worry about wearing a pair of vise grips as it blasts open.
Wow, why is this technique no used more often? I didn’t know bike tire tubes go up to 5 inches.
Here is a newbie question (bare with me). In order to make the CF pipes I would first need to mock them up in metal. Once that is done I could make a mold of the piping, which I am assuming would be a two piece mold. Once that is done buy some tire tubing, slide a CF sleeve over the tubing, add the resin then pump her up to push the CF sleeve against the mold. Sound about right??
Another newbie question (I know FNG :lol: ). How would I got about making the mold? What materials? I have read the mold must be polished with a buffer but, that would be near impossible with this tpe of mold. What type of CF weaving would be best?
These questions need much more reading through the stacks of info before you would even begin to understand.
Take the time to re read all the earlier questions. it appears that you jumped into a thread that interests you and want to be educated. We have all put way too much time on these forums to take the time to educate you without you doing some reading first…
I hope I don’t appear to be upset. I just know that we can’t answer this in a short timeframe judging from your question and how it was understood from the previous posts.
there are only 6 pages of posts,would take you an hour or so to read,thats wat i did 
its pretty much all in there…
check out this piping!
what kind of release agent would you use on the bike tire? obviously can’t use pva… just lots and lots of wax? or will te cured resin not stick to the rubber?
I use a spray mold release and spray it on while the tire is inflated, and wipe it down real good. Then I deflate the tube and leave it alone til ready to use. Keep it stored in a clean plastic bag.
I have also wrapped it in saran wrap.
those are some F’ing nice works of art. I’d love to see how the molds fit together on that one.
