CATAMARAN BUILD - Wiped Out by Unidirectional (MJ Sailing - Ep 191)

[@samsaraadv8965]

You two are hardcore!!! I could never do this as I wouldn't have the patience. You guys make it look so easy and I know it's not.. Enjoy the beer breaks for sure. Loving the Build.

That look on your face Matt at 13:08 was just classic. I absolutely can feel your pain buddy. Jess you are a total legend, my Janet has been dragged willingly into every boat build as well and digs deep when needed. I need both of you over here in Aus, I could really use some good lamies. It was also excellent to see Jess with a massive methacrylate smear on your jeans a couple of weeks ago, after you challenged me to a neatness challenge with the gloves. Hah. Enjoy that beer.

That was a great explanation how the fiber orientation and width result in an I-beam with increasingly flexible sides.

The manufacturer should pay you for showing the difference in construction compared to some not to be named French boat builders. :)

Hi, I’ve been following you from Indian Town that I stopped at in 1997 on my way from Massachusetts to Naples,Fl. , to finish up working, and enter retirement. Will be 80 in July, and retired from City of Ft. Myers Yacht Basin. Did lots of work on the boat, getting it ready to make the trip, and to live on.

You two need to try using short adjustable extension polls that I have found while forty some years of coating projects,will get you off your butts away from some of the fumes and will give the ability for longer strokes while applying more pressure leading to getting more done in less time especially since you have the cure times you are working with. Also, there are 12 inch pressure rollers out there . Really am in joying watching your build , just make sure you change out your filters as soon as you smell any fumes or get yourselves a fresh air system.

[@BjrnOttoVasbottenbjovas]

It is a crazy project, but I have no doubt at all you will finish it in style!

[@robertpeterson9347]

For long layout lines, you guys need a Sumitsubo Japanese Ink Line. It works exactly like a carpenter's chalk line, but uses ink. Measure and make 2 marks, stretch the line between them and snap the line. Long layout line finished. This would save you tons of hours during the build over making little dashes and then using a straight edge to connect them into a line.

[@MJSailing]

The only problem is we were working with curved surfaces and multiple heights. When we were using the laser level for the dashes, it was because we needed to match up the lines marked on the webbing, sitting in the middle of each hull. I suppose a chalk line could have been used for the deck, but we were already too far down the other path. 🙂

[@robertpeterson9347]

First, I know the videos are well behind where you are actually at on the build so this is probably too late for you but it might help others. For clarification: An ink line is not a "chalk line", it's an "ink line." Chalk will leave dust on the surface and cause adhesion problems with the resin and fiberglass. Second, chalk can be brushed off while an ink line is what it says it is, ink. Just like with a marker, it's there unless you remove it with a solvent or sanding. The point is that with one, you only have to make end marks and then run the silk cord between them and snap the line. It literally takes mere seconds instead of minutes to make your line. And it's perfectly straight. For curved surfaces, you can use "high spots" as the locating marks. If you use 2 ink lines, one red, one black, you can use one color as the "stand off" line to be used while laying the glass. This is the tool used by Japanese craftsmen when they built fine woodwork from centuries ago to the same tool being used by them and other craftsmen today.@@MJSailing

[@louwilliams8528]

I spent a number of years as a cabinetmaker/ handyman. I found out that most of the major brands of tools have lost the quality and reliability that once was normal even in their pro series lines. In the end my main tool brand was Hilti. They make a lot of tools and after years of daily use I ever had one go down. They cost more to start but they last. You will save money in the Long run..

[@errolseager1292]

You do realise that Hilti is simply a branding name and they don't produce what they sell, their range is cherry picked from various manufacturers and rebranded with their logo, if you can identify the manufacturer you can save a lot of money by buying the original products, for example, their impact wrenches were Makita, the main thing in their favor is that they select the best tools from the various brands so their offerings are generally of a high quality.

Hitachi has been renamed as Metabo (Japanese), as is Makita, which is what I would recommend. Bosch is German and is also good quality. If you’re gonna want tools to take with you, you’ll want to go cordless. Working around the shop for two years, corded may be the way to go.

Just watched your latest video, I did a very extensive fibre glass job on my Trojan 32 in 2010, the grinder I used is a Walter mini- plus 4.5 inch model 6255G. It is variable speed 3000 to 10,000 rpm I cannot say enough about this grinder I have used up to 7 inch 36 grit discs for fairing large areas and 5 inch for most other jobs. I purchased it in 2002 and continue to use it today still the same brushes the only maintenance I have done is changed the gear grease in the head and blow it out with compressed air. You won't regret buying one. A tool I wished I hand when doing my fibre glass was a pair of electric scissors that I saw Andy on Boat Works Today using they can be purchased at. James Town Supply there is a KZbin video of them in use. Check out these tools you have a long way to go they will make you job easier. Keep up the good work.

[@MrOso36]

In regards to your orbital sander, if you have access to a compressor you could go with an airpowered orbital sander. They spin at a higher RPM, run cooler, will last loner, and are easier to repair. We use them in production furniture making and they will give you a better sand than these cheaper electric/battery powered ones. Will really come in handy when you have to do the sanding for the finish.

[@sailingcitrinesunset4065]

Nice video

[@zzlee14]

[@soupernerd8975]

Hi guys, when you are marking measurement, try making an arrow instead of a single thick mark. Pencil/marker tip at your measurement then swipe left backwards, go back to measurement then swipe right backwards. This will give you an arrow and more accurate mark. This way you dont have to make sure single line marks are straight.

[@tonyfromaus7855]

Question: If you look at 8.15 and the deck height against the background, you can see a bit of flex in the deck as you move across it. Is it a problem for tabbing in the bulkheads since they won’t flex but the deck will move vertically a bit as you walk and crawl over it? Does that movement on curing glass mean that it gets a void or weak spot? Enormous respect for what you are doing…. Truly a labour of love and something to be proud of.

[@franksmith3602]

Good luck to you 2. U may want to invest in a 1000 cheap paper jump SUITS. Each day you toss them in the trash. The amount of fiber glass dust, toxic fumes. All of your cloths will have fiber glass fibers in them. Good luck. In about 4 years I look forward to the launch.

[@lyfandeth]

If you used a credit card to buy the sander, many add at least a year to the warranty. So if the tool is newish, check your dates. This is also why body shops use air tools. The compressed air keeps "leaking out" past the bearings and preventing abrasive dust from grinding them up.

[@netpackrat]

With the electric tools, no worry about the tools depositing oil and moisture from an air system on the laminate surface as would be the case with air tools. Easier to be sure you got all of that oil and moisture off a car body repair than every square inch of a huge catamaran.

[@lyfandeth]

@@netpackrat And yet, an entire industry finds that using oil free compressors, moisture traps, and other means, is cheaper and more effective than replacing electric tools. For one boat, consuming some electric tools might be more effective.

[@netpackrat]

@@lyfandeth Yup. I literally grew up in a tire shop, my family also ran a body shop and I now work as an aircraft mechanic, so I am well familiar with the pros and cons of air tools. It would take a fairly large (i.e. expensive) compressor to keep up with the amount of sanding and grinding they need to do. They'd need to construct a piping system for the tent because running a hose directly from the compressor is a recipe for moisture and oil at the tool. Also moisture and oil traps are never 100% effective, particularly in a humid climate (right next to the ocean). Our shop was about 100 yards from the ocean and we never really completely solved our problems with paint blistering due to occasional moisture getting past the traps, until the advent of turbine HVLP paint systems.

[@jameshull6776]

It's most probable to late but just in case or for future reference look at FESTOOL for tools. For replacing your sander I'd recommend the Rotex 150 ,it is one of the most versatile sanders on the market and good luck trying to brake that one.I'm a carpenter and I can't recommend this brand highly enough. Good luck and keep up the good work.

[@macman6107]

Hi Matt & Jessica. I've just crammed all of the videos for this build over the last 3 nights and what you are doing is amazing work. However, I have a question. I have no idea if this has been asked as I haven't read through all of the comments from fellow viewers but I know you haven't mentioned it in your Q&A segments. When you're building a plane, helicopter, car, motorcycle etc. in many countries, you need to comply with various regulations that get checked and signed off by engineers during the build process and on completion of the build saying the build complies with all necessary codes/regulations etc. That's for your protection, insurance, but also for future owners to reassure them that at the time of assembly the craft met all regulatory requirements. I know you aren't even thinking of selling the boat but there will come a time (hopefully not for many decades to come) where you will no longer be the owners of the boat. So my question is this. How is this being addressed with this build or is there even such a requirement for boats? I ask because other than seeing a neighbour building a huge boat in his backyard back in the early 80s I have never watched a kit such as this for a boat being built until this series. I eagerly look forward to seeing your future videos on this build and yes, I plan to catch up sometime on all of your other videos as well over the coming months. Thanks for the in-depth explanations during this process. Although I'll never build a boat it's still entertaining to hear how individual people tackle these processes. I hope you get to see this question or, if anyone else could answer what the process is for such a requirement is in America that would be great. All the best. Craig.

[@henrystraley7384]

When I mention SV Parlay Revival the work you are doing on the bulkhead footing and then the fiberglassing the bulkhead to the footing, it appears Lagoon did not do that instead they used epoxy filler 2 inch wide to glue the bulkhead to the footing. That is why I suggested you talk with him. You are taking your time and doing a much better job and doing extra to fit your needs and your security. That is what should happen on every boat built.

[@lowellmccormick6991]

The only difference between Imperial and Metric is the tape measure you use in the shop and field and the template used to start a drawing with in AutoCAD. Green lasers can blind you very easily. My pretty good quality red laser level came with a pair of red glasses. They work well for seeing the dot or line at extended distances.

One trick I learned from another youtube channel is if you tear the edges of the fiber glass so it is frayed then it is easier to sand, rather than a thick line. This doesn't apply if you don't need to sand it, if it is hidden. Just thought I'd share that if you might need it. :)

Try Rigid tools from Home Depot. Warranty for life to be repaired. “ which you need replacement right away”. So see if good for you. Corded tools for big projects is the way to go. If you do get battery tool it covers battery as well.

[@edwardnigma2216]

I've got nearly an entire catalogue of the Rigid tools from the drivers to drills, sawzalls, the routers, fans, lights, etc. I would not buy Rigid tools again. Their warranty program sucks and it's a pain in the ass to deal with. Several of their batteries have failed early, and every single time, they want you to bring in the tool, battery, charger, etc. which means that the rest of your tools are down. At this point, I have nearly half a dozen of the extended 4.0ah batteries, three chargers, and multiples of drills, saws, drivers... I'm buying Milwaukee or Makita next time it's time to change out, or hopefully the crap gets stolen. I'd rather deal with the insurance headaches than the warranty ones, and no, you do not get Rigid tools replaced "right away", unless they break within the first 30 days, at which point you might as well have bought Hercules or Ryobi and saved the money.
