I do a lot of fibreglass work. I am always keen to see what others are doing. I think some people on here have too much to say. Interesting vid. Like i said, Always cool to see what others are doing. Cheers for taking the time to show us what your up to!
Had a job about 8 yrs ago finishing a plug and mold for a 17ft rigid hull for inflatables. I believe for the us coast guard. Used this technique with fantastic results. A little bit differently but many ways to skin a cat.
this vacuum bagging method seems to not use a peel ply shield and batting to wick excess. It looks like direct to weave vacuum bagging which I find interesting. I bet it weighs alot, where is the boat sailing away ? More boat pictures please ...
Damn, big ass hustle to get resin in each area!! Funny thing is that this procedure is the easiest way to do it! Wonder how many litres of resin it went into that hull!! ?
Hi, i need some big fibreglass moulds made around i cant find a company at present that can take it on.if i made a templateout of ply timber can i coat the timber in the fibreglass resin sequance and create my own mould. also it needs to be quite strond so can i install timber in places.
Chopper guns are great, but chopper guns only apply CSM which still needs rolling out, they do not apply core or W/R layers. VI mean 3 people can lay-up and bag a 40-50ft hull in a day and achieve a more even saturation. Admittedly this firm do not seem to see the labour benefits of the infusion method and still have dozens of people standing around. Infusion is very risky if you do not know what you are doing… if it starts to cure before complete saturation the whole piece is usually scrap!
Arun, Yes chopper guns have been around for a long time.....there is a reason for it. Cost! If this was carbon fiber I would say this is the only way to do it, but not fiberglass, core mat construction we could do this with a chopper for 2.40-2.80 per ft/sq that is with labor. How much did it cost with infusion....?
Fred, Yes lets take it one by one. 1. progress give me a break that is not a reason to choose one method over another. 2. "fiber rate" our chopper puts down 43% glass with 1/8" laminate. boats always need stitched mat on the bottom of the hull which is usually hand laid after the chop and that increases the "rate" to around 45-46% because it is usually 20-24oz mat. 3. stronger lighter- Yes a boat made with this process is bound to be a little lighter but a what "cost". emissions please GELCOAT!
No not at all if you know what you are doing. 3 guys and a chopper we could do two 2 of these in 8 hours. With a cost of below 2.80 per ft/sq. Try to get your cost lower than that with infusion not going to happen. If your making a racing boat, high dollar carbon fiber then yes infusion is the way to go! Not for glass though the benefits do not out weight the cost increase.
Imagine the quantity of tubes and plastic foil thrown away for each hull! There is no cleaning of any of the used equipment after 2 component resin use...
Hi Jeevan how are uthis is Mangaleswarren from puma boat yard PondicherryI left Pondicherry back to Canada/I show your 43 feet boat resin infusion it is very good and neat.RegardsM.Mangaleswarren
No not a all we make drainage covers that you probably run over daily with your car or truck, bathtubs....ya most of them are crap you got me on that one. Our tubs are high quality and you can buy them at home depot or Lowes. Chopper guns are only as good as the operator, like a computer, and we have gotten very good at perfecting values that are as good as RIM manufacturing with 1/3 the cost. The only drawbacks are fumes, part thickness and weight but those are not issues with a non-racing boat
health risks? Is the gelcoat not applied to the boat? What about those fumes? Our chopper is very consistent it all comes down to the operator. Elkhart, IN is the capital of fiberglass we do all kinds of transportation production parts, thousands of boats per year. Everyone in this area uses chopper guns! Yes it is not as "cool" as infusion but infusion is much more expensive, molding as well because of vacuum, and in some cases it just is not practical. Fiber rates of above 40% with a chopper!
You don't use chopper guns at all? Infusion with a process like in the video is a ton of work. Does it make a better part...yes; is it a process that is a look what I can do moment....yes. You can get a quality product from both infusion and open molding process' one is just way more expensive than the other. Overall good job though.
That resin is bad mixed, use the two container mix method, mix part a and part b in one container pour the mix in other container, scrap the mix over the sides of the first container and mix again.
people around that can do anything you desire..you just have to be willing to come off the pocket pocket..We are a full service custom composite shop...look up our website Harbor Master Fiberglass 32034
wooden wagons worked to get from point A to point B in the old days,,,You can still choose that form of transportation everyday of your life ,if you so choose [In America anyway]....But I bet you drive anice car or truck,,huh???much more efficient ,drier,quieter,smoother and you dont breathe in manure ,,,save the wagon for the hayride in the parade!
Amusing to think there is somebody who knows enough about moulding that he mentions the chopper-gun but so far out of touch that he doesn't realise that it went out of use decades ago. Chopper guns fire a mix of chopped strand and resin at a mould quickly and easily, but inconsistently and unreliably. It makes for very heavy moulding of poor strength to weight. Its now considered a very low-technology for poor-quality mouldings. And a health risk to the operators because of the vapours release.
seems like spraying it would be much easier, and if your standing on it as it tries to fill between the plastic and boat that is going to screw up that area. still watching a man is standing right on top of it , that is going to thin that layer in the size of his shoes . hum
+Terry Holden Its so much lighter when you do it this way . There is also much less air , which means stronger . The guy standing on it isnt going to do any damage . the entire bag is pressing down with tons of force . the vacuum inside makes the air pressure outside increase immensely . which is why the liquid will run all the way along the bag . his 120lbs per square inch is probably one third what every square inch has exerted on it during this process . Thats about 10,000 dollars worth of tubes resin and fiberglass and bag. what a deal . but theres also ten guys your paying to work . Glad hes in india where a dollar is worth about 60$
The vacuum inside the bag does not make the outside pressure change at all. In a perfect vacuum the most pressure that can be applied, at sea level, is about 14.7 lbs per square inch. That's about a ton for every square foot. It will be less at higher altitudes. That worker would only apply 120 lbs per square inch if he were to stand on his tippy toe. Standing normally he applies between two and three pounds per square inch.

Ever heard of progress? Higher fiber volume rate? Stronger lighter laminate? Lower emissions for the workers? Perfectly placed fiber archetichture not just resin rich chopped strand?.
What resin did you use and what mix of catalyst did you use to get 1hr flow before curing started?
How do you keep the "polyester resin" from absorbing water when Cured?
So how long did this process take ? Ingenious BTW. Thanks!
does this process mean you no longer need a temperature and humidity controlled environment?
Thank you very much.
damnn, i love boat making

Impressive could u tell me what vacum pump u use?
Mantapp

what hardener u r using?
@ajikumarb it normal polyester resin with 250 visco.. & MEKP
@HENSLEYDMB ... yes very long back...

@Toolkasine1 thanks by the answer!
hey if this works, what ever floats your boat...
Sehr schön! :-)
Kikay ni?
2:02 Hello Neo, follow the white rabbit :D
This is the latest tech, it really gets the resin in there... I bet it's strong as can be...

@fabiob3d If you do that there is a risk that the resin will flow faster than the vacuum can suck it, this can lead to resin lakes between the layers.
@tigesinaus yes..

If they can do this why can't they build yacht catamarans? For sale
Thank you

@Alfredo9936 I like making replacement body parts of my '77 Ford F-150.
valeu
thank you for showing the process
from where you are getting pipe, pipe fitting and such a big polythene .kindly let me know
If you need let connect am in UAE
9:28. theres 1 of them topping up the resin bucket followed by another phone order for a tandoori chicken and a vindaloo
impressive can I know the manufacturer details
i think this is the same crew who mend the quantas airplane with a aluminum ducktape.
What is the company called?
Imagine the quantity of tubes and plastic foil thrown away for each hull! There is no cleaning of any of the used equipment after 2 component resin use...
dapen ur pound w a softer foam low dec obv a safety hull
they are stepping on the resin...footprints in the "resin"
Hi Jeevan how are uthis is Mangaleswarren from puma boat yard PondicherryI left Pondicherry back to Canada/I show your 43 feet boat resin infusion it is very good and neat.RegardsM.Mangaleswarren
What is the cost in 2016 currency to build this hull? Do you offer your services using owners molds?
That's the question I'm interested too
shouldnt the resin be in a higher level than the mould to it goes down "pressurized" ? It wouldnt make the process faster ?
No not a all we make drainage covers that you probably run over daily with your car or truck, bathtubs....ya most of them are crap you got me on that one.

taht side shape is universal
thats a support pull after u flatter er up ur hull was pullen so ur air was dead
final load adjustment
as long as 4 feet doesnt bother pretty much
make it so u can bolt ur mod on front 10 feet
health risks? Is the gelcoat not applied to the boat? What about those fumes? Our chopper is very consistent it all comes down to the operator.

And they do not "fire CSM" we spray roving CSM is on a roll that you would use for hand lay-up. But you knew that right.....
You don't use chopper guns at all? Infusion with a process like in the video is a ton of work. Does it make a better part...yes; is it a process that is a look what I can do moment....yes.

thats 4 all seas id runahh
a dorreea
Ever heard of a chopper gun? Way overkill

a hole should nt sotften it should sweell

Lots of close up shots of the yellow crane cradle thing, and a lot of people standing around. Nothing really about a boat.
Just wave the camera around, that's the way to make a video.

chopper guns are fast but the end quality is crap.
