Here is the newest mold I made today. A double Evolution 8 Exhaust shroud mold. Here is the plug efore I shot the gel coat
problems those inserts are ace!
Ive so got to get myself some of that tape, i messed up and got gaffer tape instead - got about 3 rolls to use :lol: (nice dimple surface on my flanges lol
i was just making a mold for those over the weekend.
Problems…what is the lay-up material order your using there ? G/C, Twill, then what oz. of glass and how many ?
Also how ridgid would you say the parts became ?
Oh, and the overall size of teh parts too ?
thanks, Vinny 8)
are you asking about the cargo cover? door panel inserts? or the exhaust shroud? 
how do you manage to get so much done when you are always on this forum lol :lol: i think it should be renamed-problems cf forum 8)
I suppose any of those for general lay-up order.I’m trying to judge an end ridgidity from some of your parts. I’ve got to do some unusual parts ,and your input might help me gauge the weight and number of layers and Oz. choices I make.
I leave my computer on the site all day so most of the time it shows I am online all the time.
the cargo cover, say for the 94-01 integra it is a littly flimsy, because there is not much side support but I found areas that I made thicker to stiffen it up without adding much weight. It is 1 layer 5.7oz twill and 4oz of continueus strand mat. That is the general layup for most my parts. The door panels are very ridged because os the contours of the part itself. The exhaust shroud are very flimsy. Mainly because they have gel coat and VER. These are only 2 layers of 5.7 oz twill. They just go over the bumper and don’t need to be more then this. I have made some with 3 layer infused with epoxy that are a lot stronger
the integra cargo cover is around 42x12x3
the door panel inserts are 34x8x4
and the shroud is 6x8x6
OK,thanks Problems…that gives me some thing to consider for sure.
Can I inquire to which brand of VER resin and G/C your having your turn out with ?They are looking great by the way !
the gel coat is made by velspar and the VER is made by RCI. I get them at composites one in salt lake city
OK thanks for the info. Can you remember how quick your larger parts are infusing ?Once you open your hose clamp/valve .Til full saturation ?
the integra cover will fully infuse in about 1 to 1 and a half minutes. I am thin the VER down 20% with styrene. This is so it infuses faster with less resin
Darn…that IS fast ! You don’t find yourself getting any print through/readthough while thinning the VER ? I would think you’d experiance some final shrink doing that in a few days/week ? If not then, cool.
I thin it for one main reason, the VER I use is not made for infusion because it is normal VER. The infusion VER that I wanted is the exact same chemical makeup as the one I use but after calling the manufacture got him to tell me that it is just thinned with styrene and one other chemical that prolongs shelf life. So by thinning out the resin then it is almost identical to the $75 more per 5 gallons infusion VER. I get styrene for $70 per 5 gallons
OK, I gotcha’ . So back to the cured print through…get any at all ?
no I spray the gel really thick
What kind of gel do you use that is compatible with epoxy?
Marius
I spray on a duratec top coat if I am using epoxies or i will use a UV epoxy and no gel coat
good work 
I would think that styrene is okay to thin any VER ? right? :?: :?:
Iam still havin trouble with flow
How many layers of flow media are you useing?
