Infusion Plan

it feels cool, feels tough! I have a feeling this stuff is going to find it's way on to more boats … and the GatorGlide as well! It's not like paint, it's more like goop until you have it all mixed up, even then it's a really thick paint.

 

Do you think it would take to some sand topsides? I have used petit with great success.

 

I think you would need something larger than sand... Or you could just roll it more aggressively for more texture. I let it dry too much in one area before re-rolling and that turned out super non-slip, had to sand it down.

I already ordered the kiwi grip ... Going to apply with minimal texture.

This liner is 40 mills thick, I sanded on it with an orbital sander, wiped it off with a rag and you can barely tell I sanded it, tough stuff!

 

Thanks for the update. I am watching with great expectations.

 

You must be getting close eh Jorge, im looking forward to seeing your thoughts after sea trials.

Steve.

 

Touching up fairing on deck and working on console now. I designed a pretty cool pickup-truck-looking platform/console, at the very least I think she will look great

Here is a pic of the boat flipped, I lifted the bow a bit so the aft hull is about parallel to the floor, the angle is not that bad and I think I have enough flat plane area ... back there about 30 sq ft to get up and stay up pretty easy ... my biggest worry would be porpoising and being unstable, I think flaps would resolve that but with the tunnel sucking the back end down it's hard to say, could be the boat runs just right LOL!!





Bought a hex-copter (drone) in anticipation of filming the sea trial but I still need to get the trailer made and the metal guy has three platforms to build, bow-casting, aft poling and the platform for the console.

The console platform is going to be about 16" raised off the deck so I decided to hang the tank underneath the platform which opened up some cool ideas for storage and tabletop space.

I'l post a few nice pics in the next weeks once the boat is painted and then when the metal work is completed. And then of course the sea trial.

Cheers

 

She looks fast just like that. How big is the fuel cell?

 

Yeah she does but I will be happy to cruise around 25-30 with a yamaha 70hp ))

the tank for the boat is 22 gallons, my current one is 21 gallons, I think the most I have burned in a day was 10 gallons and I must have done 60-70 miles.

or are you talking about the drone lol .. it flies with three lithium batteries, I get about 20 min fly time, range is pretty much line of sight since I don't have drone vision, otherwise I could set it up to be as far as 80 miles ... if I lose contact or the batteries run down, it automatically flies back to a pre-specified gps coordinate.

Waiting for the new gopro's to come out, (next mo I thnk), 30fps - 4k is a game changer!

 

Very cool. I have a 4 stroke 60hp Merc on my pontoon boat. It is a real gas sipper I have burned maybe 12 of 18 gals in an entire day. It rolls about 8-12 mph non planing and deep slicing hulls. You should have no issue with 25-30 on this hull.

 

Figured I would post some pics of the deck paint … I don't know, maybe too much green going lol … I should have painted a white star on her!

 

Hi jorgepease, sorry for my scholastic language...
Hi write from Italy and I saw that you for some work, you used MTI tube right?
I beginning to use now and it seems a good material but I use only for little piects and I would ask to you some advices:
how seems this tube for infusemedium hull (25/30 feet)?
Is better this tube or traditional line (spiral with resin trap)?
Can MTI tube ensure a perfect air aspiration and a perfect walking of resin during infusion, for you?
As you, also we for our shipyard, we using Gurit SP Prime 20 and honestly I'm happy of this resin also if for me, when start injection, there are a lot of micro bubble, but this is only a visual problem!
Thank to all and sorry for out of discussion.
Ivan

 

Hi Ivan,

It's good stuff but if the resin racetracks and surrounds the hose it cuts off the vacuum enough that the rest of the resin front slows way down so it can't be used as a substitute for a good infusion strategy.

When I started infusing inward to a single point, or to several single points, I felt like I had much more control, the resin just seems to flow better and I liked not having a lot of hose marking up my part.

If you look at the last infusion I did, I divided the boat into quadrants and each quadrant finished infusing at different times. Since my feed lines supplied the adjacent quadrant, I could not clamp them off so instead I just clamped off the single point vacuum for the infused quadrant and let the resin keep flowing freely. When all quadrants had infused, I clamped the resin line and re-opened the vacuum lines.

I would always use a resin trap but the proper infusion should not pull resin into the trap. I always pull a little resin into the trap because I wait too long to cut off the feed. I suppose I could use a small 2" long piece of MTI at my single point outlet, in which case, a roll of hose would go a long way.

Also I really like the prime 20 too. What I started to do in the end was measure the resin into the infusion buckets the night before, then all I had to do was add the hardener and mix and no air bubbles!! The pinhole leaks from the bag are a PITA, in the future i will buy the best bag material period and have a nice size flange so I can do a good job sealing.

 

Hi Jorge,
thank for your reply!
I did some tests with and without MTI hose and seems that the speed of resin is equivalent ...

But into the big mould I'm not sure of a perfect functionality!

We must infuse a hull of 8 meters (about 27 feet) and I know if use a classic spiral or MTI hose.
Being overturned hull (one off), aspiration line we will put in central keel and the line of injection (diameter of 15 mm) will be in bottom (right and left) and every 60/80 cm it will be another lines of 12 mm that go up about 3/4 of total height that is about 2,2 m

What do you think of this positions?

Gel time of resin will be about 50 min to 25 °C so in this time don' t should be problem of gel.

I don't like old system with resin-trap because the epoxy resin has a long gel time after infusion and so there is always the problem that resin can go out from laminate because get and maintain a perfect vacuum in this life is impossible!

 

the fishbone layout is what a lot of people use, I would put a few layers of flow media under the hose feeds and outlet or look into alternate transport method such as Groper devised on his build, otherwise u will have a lot of hose marks in your finished product!

Yes speed is same on both hose types, just don't expect the flow to continue if the MTI hose becomes surrounded by resin is what I am saying, if your just using it to prevent resin exit in the event of leaks, that is a good use for it ... But everyone here will tell you don't infuse if your bag is leaking ))

I would spend the extra money and use best bag material or even double bag, that is how much I jate pinhole leaks lol!!! ))

 

Yes, it is right!
The first thing is a perfect vacuum into the mould but the perfection is impossible...
I was able to get vacuum from -0,99 to -0,8 for 2 hours in a bag di 10 sqm but to have a perfect vacuum (-0,95) for all infusion in simpossible...

Have you had problem with MTI hose sometimes?

Are you accustomed to use a resin with long gel-time and do only injection or a short gel-time and inject in more points for don't have the problem of pot-life into the bucket?
