- Thank you for your support! Have you ever wondered how to build an extremely high performance boat hull on a budget? In this episode, I’ll show you how to glass in the transom knees to make the transom absolutely bomb proof, and install the composite stringer, WHILE being filmed via drone! As far as I know this is the first stringer installation video shot via drone, so this is a world’s first! My girlfriend is also going to show you how to make thickened polyester resin in 1 gallon ziplock bags for easy application, it’s sort of like frosting a giant cake. We’ll then experiment with the Carbon Core Honeycomb panels, and try glassing on a layer of biaxial fiberglass with varying success; feel free to leave any tips for us in the comments below.

The success of my SST project was pretty unexpected; viewers like you helped pay for the fiberglass resin & supplies needed to finish this project! As a thank you, I'll be doing a new video every sunday; Sleekcraft Sundays!
I picked up a crazy rare ultra high performance twin tunnel hull ModVP Sleekcraft SST for $500! This was one of sleek's fastest hulls ever, and was famous for racing in the ModVP series in 70s/80s/90s before it was banned for being too dangerous! This thing is going to need EVERYTHING, but I'll show you how you can tackle all these major repairs without spending a lot of cash by doing almost everything yourself.

whiteside bits for the router are a game changer
Honestly these chinese bits cut the coosa like butter. But yeah, I use Freud on hardwoods and whatnot.
Y’all are doing an excellent job. Only way I know of to get ahead of the resin kicking off on your bi-di is to use a chopper gun with the air motor disengaged so that it’s only spraying resin and catalyst. Other than that the only way I know of is to do it the way you already are with less catalyst. The customer service boats that I did needing transom replaced were up to Crownline 330 cabin cruisers that had the spiral staircases. I had to work the glass the same way you guys are because the company wanted the engines left in. Had to repair two of them in the parking lot around July/August wearing a Tyvek suit,believe me when I say that I feel your pain. You’re saving an immense amount of weight using the composites,that boat is gonna be an animal when it hits the water! You two keep up the great work,you’re doing an excellent job.
Hey Lou, funny seeing you here! These are a great series of videos. Hope all is well!
@@PBZKYLE Hey buddy,doing pretty decent. I was just thinking about you the other day when looking into swapping semi wheels onto my dually. Was thinking about your Nova and realized I have 4 of them and need to slow down on my collecting,lol. Hope you’re doing well my friend.
You can slow down the kicking time by sitting your mix on an icy pan so the bottom about inch and a half of the resin bucket is in the icy slurry.
That's what my buddy Yacht Doctor taught me some years back, and it works out great on all the restorations we do when we're in odd spots that we just HAVE to have that slightly longer kick time.
Precoat your cores with laminating resin to avoid the issues you had with the Nida-Core. It is also important to precoat cores to avoid glue starved joints. Cores like Coosa absorb a lot of resin. If they are not precoated they will pull all the resin out of the fillets and/or glass leaving a very weak bond to fillets and dry glass.
Yeah, figured that out after the first one. :)
Installing the stringer in a speedboat. Where the stringer meets the boat can split along the stringer. To avoid this, I mix resin with cabosil and lots of wood dust or microballoons.
Install the stringer about a 1/2 " above the glass. Bag in a soft smoots and make stringer feet from that. You want a 1/2 circle curl under the stringer. This helps spread the load away from the stringer to the feet. Lay feet in 2- 3 " out from stringer each layer. this keeps from forming a stress crack. Also should have mat layers between roven for lamination. Roven is only impact strengs. Has no waterproofing or lamination strength. That foam we have problems with if not scratched up with 18-24 grit by criss cross by hand.
Cover all work to be painted with several layers mat to keep the glass print from coming through.
Use slow hardener, for prepping larger sections, particularly in hot climate
Super excited to see this uploaded this morning. You've got me wanting all kinds of boats I don't need now.
Go for it!
By lateral cloth . Use a roller with 3)8" map. Place cloth on large piece. Fold in half or thirds depending on length. Pour resin on flat surface and spread around and back side of cloth. Fold it over and take other side and do the same thing. Put back flat and quickly use bubble roller. Then pour resin over top and roll with map roller always having wet resin in front. And pull it to the edges . Let excess fall. Takes skill to eyeball the perfect amount. I always leave a few ounces to finish so I'm not waisting.
That cloth is hard to use when wet.
When doing large areas of biaxial like that, lay up a GENEROUS amount of resin onto the surface of the nidacore BEFORE laying the glass onto the core. Then, immediately put the 1708 on and go to town with generous resin and pressure.
You can also create a tack layer. Put a thin layer of resin onto the nidacore and let it cure overnight (kinda like when you precoat plywood for next day layups). This will create an extremely uniform surface for the resin to better grab into mechanically (on a micro level) once you lay your 1708 onto it. The resin on top of the 1708 can then be swashed all around easily with a squeegee, without bleeding out under the 1708 because the tack layer is already there not allowing "slippage" or "under fabric creep" of the resin.
Awesome tips! We'll try it, thank you!
@@ADDvanced no problem man. Every time we have to do Coosa, Divinycell, or any composites like that on flooring or large bulkhead walls, we typically use the "tack method" I mentioned above.
Think of it as kinda like creating a "sealant layer" that stops the resin application from oozing everywhere other than you want it to when wetting out the glass.
Also, you don't have to do entire large sheets of glass at one time, because you don't have enough time usually before it kicks. You can split the glass in halves or thirds. Then, just make sure the edges are frayed up and kinda mesh them together as you go like when you put a carpet seam down. Do one section, get it done at least until it gels or right before, then move to the next, and so on. That's probably the easiest way to do your setup like that without vac bagging and etc.
(I own White's Carb & Marine on Lake Erie. We mainly do boat restorations, stringer, and transom jobs that other outfits end up bidding wayyy too high on haha.).
the double ply biaxial cloth is for building the hull and doaks up gallons of resin.
just install the boards and gel coat the inside of the boat
Fun as always, thank you! And now with ratty looking Chipmunks!
Yeah one of them had a cuterebra on it's back; Sarah got it out and kept it from getting infected. +1 to Chippy Bois
@@ADDvanced I had to Google that, I'd never heard of it. Freakin' gross dude!!!
@@paulp7692 lol yeah, that's what that lump was on his back. She got him to stay in one spot and lanced it.
@@ADDvanced Also, I wanted to make some light hearted remarks on Sarah, but I know from experience that Sara's with no H get totally pissed off about the spelling, so i refrained. Let Sarah know it's off the chain now :-)
Instead of using a chip brush, use a 3” 3/8’s nap paint roller. You can add tons of resin with the roller. Then use a bond spreader to move the resin around into the fiberglass cloth.
Good idea; do you think I should be prewetting the nidacore or just prewet the back of the biaxial mat, apply to the nidacore, then dump on more resin and roll flat?
Just wet the nidacore then lay the cloth…. Apply resin then. That’s a lot of material to wet out before you apply it to the surface…. It’s hard to handle. Just like when you was pre-wetting the 6” tape when you tabbed the transom. You didn’t have to do that. The cloth you are using is thin enough to absorb the resin. Now if you was using epoxy that be a different story, because it’s thicker that the poly resin. So wet out the board and lay the cloth then roll with a 3/8 nap roller. Then thin roll the air bubbles out. Before you use the roller that some tape and get the lose fibers off the nap roller. So it doesn’t come off in the resin. Hope this helps.
Great job guys can’t wait to see it in the water. Also good to see how kind you are to the squirrels. 👍🇦🇺
"the gang restores a sleekcraft"
Holy crap, that was an awesome shot. I need a drone.
That was the last shot of that drone, it promptly got a mind of it's own and punted itself into the concrete a few days later. Don't buy DJI.
Good stuff learn as you go and share mistakes. We all learn together, awesome brother God Bless
If you don't try new things you won't learn anything new.
Yes another excellent video 👍👍 for Sarah she battles ants drones and jokes your work is outstanding I love your hats and the end of the video was priceless thanks I really enjoyed it.
Glad you enjoyed it 🤙. Excited to make more progress, wish it would stop raining lol
"We're like fricken experts" Definition of XPERT: X is the unknown quantity and spert is a Drip under pressure. XPERT, Enjoying every minute of your vids.
Awesome! I encourage you to make a poor financial decision and buy a high perf boat project :D
Boatworks today just did a comparison video on refrigerating resin to prolong it's working time. It made a huge difference.
Awesome idea!
Glad to see your not the only one with a Milwaukee addiction
I used to work there; I designed the grinder I've been using, the utility knife I've been using, and a lot of the bit cases. lol.
@@ADDvanced You worked there? That’s fricken crazy. I’m a general contractor and I’ve dropped Milwaukee tools from all different heights and beat the hell out of them and they always work with no issues.
Really loving this boat re-do! Something I'd like to do, but I know, I'll never do....
It doesn't cost much! I have less than $1500 into the hull at this point.
Thx for the journey. So nice! you’re a perfect team. Hope to get my wife to help me with boat jobs. Keep up the good work and spirit
Boat looks great having fun watching, Love the always sunny in Philadelphia. Wish I had saved all mercury marine signage when I worked at the marina who knew
"the gang builds a race boat"
I've just become a subscriber to your channel
I have just acquired a starbucks tunnel and have to do just about the same as your doing.
I lucked out with the transom that is still in very good shape.
Gonna keep following this resto. Nice information.
Awesome! Do a video!
That transom should be super strong..... well done!
It'll get a few more layers this week, just in case!
This series is giving me so much hope for the 84' jet boat I just bought. You make everything look doable, maybe not easy but very doable!
It's messy and not super fun, but it's also super fun and not too expensive. If you use wood you can do all this stuff really cheap!
@@ADDvanced I've looked at the transom and stringers, they all feel solid still so hopefully I won't have to go too deep into it
You keep putting out content like this and this channel should blow up.
¯\_(ツ)_/¯
Amazing progress! Also, I'm jealous your chipmunks let you get that close! The guys in my yard are really skittish! Although, They do climb up to my 2nd story deck to raid the bird feeder. I had no idea they'd climb that high!
They're little clowns, and have become pretty tame over the years, thanks to Sarah's patience and bribery
love your epic drone footage 🤣
World's FIRST! I should be in national geographic for this 🤣
Can't wait till it's done.
On large and/or pouris surfaces don't pre wet, use tape or clamps to pre stretch glass, pour and roll from the middle, torch it until it's flat and preity.
This mat is pretty thick/heavy tho.... I'd be worried about soaking all the way through and getting a good bond. Thoughts?
@@ADDvanced Keep the resin thinned and Calculate for a slight excess on your pore, let gravity do the rest. You'll be able to see any dry spots as air bubbles, just roll and dab them out. The large pores of the material and gravity do the rest.
@@ADDvanced Also you can mix a little of the acetone in with some epoxys to thin it, it's not recommended for strength just as a glassy smooth coat or help with penetrating a wet coat.
Good morning from Siesta Key Florida
You guys should block off the bridges and secede from Florida til all this covid stuff blows over.
Great work! Can’t wait for more videos. Personally I don’t like that Amazon resin. Do you have anywhere locally that sells plastic and grp supplies? Give them the business, plus the cabosil will be half as expensive by the gallon. Y’all should really get some full face respirators with 3m 60926 cartridges!!
Unfortunately no, I checked around but not really. I did find fumed silica buckets at a woodworking supply store that sells epoxy, so I grabbed some from them, definitely cheaper. Have a 3m respirator I'm wearing in most of my videos, not sure what filters but the good ones.
Very Cool Video so nice to see the Fiberglass work. It looks like the Boat is Shaping up nice. So Cute to have your Own Chip & Dale friends. Take care you Two.👍 😩weather people Are Fake News.
😩
Thanks 👍. Chippies are constant source of amusement, they act like clowns
This boat will be magnificent when you two finish it.
It'll never be perfect but it should turn out pretty rad
Loving this series guys. I’m in the market for my own retro hull now. 🤘🏼
Do it! The whole reason I'm doing this channel is to convince people to tackle larger projects, and just chip away at them. It's how you learn.
Dude you remind me so much of a guy I went to college with. He was related to the actor Adam West of all things. You also mention CAD work and we went to school for computer graphics we worked alot in maya... this was 8 years ago... im just sitting here like o.O... Anyway, lol. Not trying to be weird. Just such an odd similarity! You guys are an amazing team!!!
Sounds like a cool dude 😂 I work mainly in Alias these days but Solidworks used to be my jam, and still use it for personal stuff.
@@ADDvanced yeah I pretty much 180'd when I graduated and havent touched any of it... it helped with some 3d printing stuff though 😂🤘
You are very inspirational I finely started to fix the floors in my 180 searay just a big thanks
You can do it man. Just baby steps, a few hours here and there, it's how I've afforded all my boats, actually.
if you feel you are using to much resin, try using vacuum bagging methods instead., that will press the the glass together and leave a minimum amount of resin in the glass cloth, nice and light. love the videos
heh, some people are saying we are not using enough, you're saying we're using too much. haha, idfk.
@@ADDvanced lol, the hive mind is great right ;) I haven't built any real boats myself, just done composites for RC planes and boats, and weight saving is key there. It might be a good idea to check out Mike Pateys channel if you haven't done so already, he builds insanely cool airplanes, and has a ton of videos on tips for working with composites.
That's starting to look mighty solid. What song is playing when the resin got delivered?
Pretty sweet.
Ps: you two laughing at the approaching storm was heartwarming, nice couple you guys make. Fun! ;)
Ps2: squirrels!!!
Thanks! If you tell me the minutes/seconds I can totally tell you the song. Lot of storms this summer for sure
You seriously have to be thousands deep into this boat
Less than you'd think. Probably less than 2k. If I had done wood instead of composite it would have been under $1500. Not including the outboard tho
Nice work man. Was thinking you might want drain holes in the knees so water doesnt get trapped. Just a thought. You probably have it figured out.
I'm not sure it will need them; I will be reinstalling the splashwell so any water intrusion would happen way forward. But yeah, I should add a couple.
Great video again guys, nice touch with the drone. With the amount of strength you got going on now a Merc 12 cylinder Verado is in order don't ya think? Just a suggestion, when the inner hull is ready for paint, maybe check out the price of using rhino liner. The same product they are using for bed liners now in trucks. Shit is indestructible and water proof. Looking forward to the next installment. TC Dave from Canada
I hate rhino liner because of how textured it is. I used a can of Rustoleum hammered metallic enamel on my last boat and it cured awesome, and has held up great for 10 years. Will probably do the same; it was so cheap!
laying a big piece of cloth is ALWAYS a pain in the ass. One way I have done it is fold the piece up and submerge it in the vat. Then remove it over the work area so any drips don't go to waste. I have also done it one half at a time. That did not work well as the dry piece kept sticking to the wet already laid side.... I also did it the same way you are doing it and to be honest, it was just as good as any way I tried in the past. Wait till you get into offshore boats and start ribbing them and installing bulkheads too... talk about bullshit!! you will think it would be easier to take the deck off, but in reality, it is NOT!!! 10 times the work and sometimes ruins the hull. They don't always go back together they way you expect and the edges press out.... sucks, but you learn from it...THE HARD WAY!
Yeah I really did not want to split the deck.... I htink I'll be able to hide the splashwell cuts pretty effectively, but we will see.
I mean basically you’d vacuum bag that lay up but you did ok.
Thanks. I looked into vac bagging but it looked like a lot of proprietary materials
@@ADDvanced it’s definitely a lot of equipment and absolutely necessary for complex shapes but a flat panel will be fine if you get the air out like you did. I want a speed boat so bad now. What outboard are you going with?
@@biguprochester Check out ep 12:
czcams.com/video/NDITKGZqpyw/video.html
What is the stringer made of kinda looks like those chunks of plastic 2x4s there making picnic tables out of latey just wondering would that be an option,should be strong enough or is that to heavy?snooky pa.helped my dad make a dunebuggy from a vw donor,i hated the fiberglass work but loved driving the thing.!!
No, the plastic decking material is heavy, not very stiff (they actually can sag over time) and most importantly it's some sort of plastic that would be extremely challenging, if not impossibly, to bond with. Coosa is lighter, stronger/stiffer, and porous so the resin soaks into the surface, making a really good bond.
Have you checked the boat is level .
Has this project stalled for a little bit??
Got distracted with the Cee Bee Avenger, check out those videos and #MercMondays! Pushing the SST build til next year, it's already mid september.
Heyyy!! Congratulations 🎉!!
Great content maaan!!!💪🏼💪🏼🔥
Would you want to sell me your little Honda Civic?
hard no
@@ADDvanced had to ask, thanks
Acetone in an enclosed space same brain cell killing effect as rum and coke with out the taste and you don’t have to wait all night for the hangover to kick in
Depending on the resin you’re using you can use less catalyst or a slower curing catalyst to give a longer working time since your not using a vacuum bag system
I'll look into vacuum bag systems but they seem sort of complicated with all sorts of specialized layers of plastic.
Just cut firm parts off
