Here is a small video of our company doing an infusion on a pair of door panel inserts. It describes a little the materials we are using as well. I wanted to use this so you guys can ask me questins if you like about how we did something or a material we used. Here is the video

Here is both sides fully infused
Here is what the finished product looks like
Enjoy 
this is a really cool video too

Cool video DT. Starting a new company?
Thanks for the youtube link.
My boss and I used to watch that show everyday on our lunch break. I was out the day that episode was on. Pretty awesome craftmanship.
Man DT…Im still too chicken shit to do that. I wrap a bunch of the peel ply around my vac line and I make sure the vac line is close to the part…
I always end up sucking in some crazy resin and you seem to not be scared of the back clogging or closing off the vacuum.
I guess Im just gonna have to bite the bullet and go up in line size…your infusions go way faster but the suck part is always waiting for it to kick hard enough to move on to the next parts.
I need about 3 more pump systems so I can move on with things and be more efficient with my day.
As far as questions…
How are you not getting weave seperation to show up with only one ply of carbon?
How do you finish the back side of your parts? I use flat black spray paint.
How in the hell are you guys adding the scoops to the hoods and making them smooth enough to remold? My pickup truck is so unpopular that I cant find a hood for it…but Im gonna have to find out where my supercharger will actually pick up air from…so I can put a naca duct in the hood! YEEE HAAAAW!
Good work!
i run 3 pressure pots at a time off one pump. So I can suck down 3 parts at the same time. Then I just infuse one at a time. Once one is fully infused I go on to the next. most of the time once I got the part fully infused and with no leaks then I just clamp the vacuum tube off so it can not suck any resin into the pressure pot. If I get a weave strech then I just cut a small piece of carbon and stick it behind it. We use flat black paint as well for the back side. As far as the hoods we just use a metal hood and the scoop we want and send it to the body shop lol. We are not body guys here plus we are limited in time and to be more effective we need to be making parts not molding scoops.
here is all the resins orca carries.

The fiberglass I am using is orca as well. I try and use materials manufactured by the same companies so I know they are pretty compatible
Well Ill have to be better about making sure I have zero slow leaks…Cause Id be willing to gamble that if I clamped off the vac line Id lose vacuum.
Ever noticed that the resin will intensify a problem? Its slick enough to make real problems if youre not carefull.
we know we got leaks the first second we clamp it off because air will start to run. If it starts to run then we just don’t clamp it, or we will take out the heat gun and heat the area where the leak is so that will kick fast then once that happens we clamp it off.
Very Nice! I liked watching your vids, helps learn about infusion and how it’s done.
My question is where and how do you attach the vacuum and resin line? Suction cups? Do they suck right down onto the flow media or is there something between the line and the flow media? How much resin did it take to infuse one door panel?
Those cellios are bad a**. I totally admire those folks who make stringed instruments… and who would have ever thought c/f would make a good instrument!
In terms of affordable production vacuum systems, why try a 2 stage venturi vac pump using a reasonble size shop compressoer, and link this to a large vac resivoir tank, which could be easily made from a discarded propane tank?
Venturi type pumps will draw high vacuums, need little if any maintainance, and most people already have a shop compressor of some sort. Propane tanks can be found FOC, and then you only have to add some pipework, cut off taps, and resin traps, then you are ready to go.
its all in the cfm. a small motor (robinair ) can pull more air then a 150 psi ventri system ever can. a ventri system can go to atleast 2.? cfm and thats it.
correct me if im wrong.
where I attach the lines are all up to the part. You always want them on opposite sides. I just use a piece of sealant tape and attach it to the flow media on the resin intake side. I used about 7/10’s of a quart for the door inserts.
I have several more videos I am doing here this week
