⛵️The two engines for our hurricane-damaged catamaran. Ep613

[@tomk4199]

Those hatches do indeed look pretty dang spiffy! Well done!

[@geekdomo]

CAD For the win! I started 3D designing for EXACTLY this reason. I was looking for a simple part and the damn thing was like $300. I used Onshape and 3D printed my own for about $3. Besides it taught me a new skill. Keep at it, beat the man!

[@jeanhawken4482]

Looking excellent

[@stephencoulter9205]

Hi Mads, Q&A - I’d be interested to learn more about your budget for the whole refit and your timeline for completion and splash along with the breakdown for how you’re breaking down each portion of the project and when you expect to complete each step. Keep up the great work

[@mlmontalvo]

I’ve been watching these videos every Sunday for so long that I don’t know what to do without one. So please take that into consideration 😂😂

[@SergeAdam]

Good work, as always. I really enjoy watching your videos every Sundays. Keep it up !

[@kevinlytle6215]

Q&A First, you do what you need to do to make this less stressful because of your desire to please us!!!! I would love to hear a Q and A and have a request that may be reasonable. If not, no harm if you ignore. You could do a sort of Q and A as you mentioned and as a second episode to buy you another week of buffer you could do a here is the stock vessel, here are the list of areas needing simple, ha ha, repairs, and here are the areas where you are changing the design to fit your needs. Not a deep dive but overview with a sort of roadmap. Seeing what could be and what is in a more self contained video would be cool!

[@45DegreesN]

Mads! Nice beanie! Welcome to the Deeeeetroit City sports family!

[@timtrampenau3050]

Having repaired industrial and commercial heavy equipment for 40 years I’ve removed many a broken bolt, when all else fails I drill out the bolt just enough to not touch the threads and then use a series of chisels including a diamond point chisel and slowly work the remaining bits out. Sometimes you get lucky and can “peel” the thin remains of the bolt right out. Cheers and good luck .

[@gramos9115]

Thank you for all this , you have a good standard of work , well done

[@williamwittman1543]

Mads, you just do whatever you like with the videos. I am always amazed at how professional your videos are. If you do a Q&A I have been wondering if you are still doing any programming?

[@jameshansen1256]

Wow! I would think a seasoned Dane could handle 40 degree weather. I’m Danish and live in Upper Michigan as well as working on my Catalina 36 cleaning the bilge in -13 degrees last week. Come on mad you’re Danish. Love your post and look forward to every Sundays program. From frozen Northern Michigan Capt Hansen aboard Gallivant.

[@alextownend7316]

Stainless bracket for the engine??? Is there an incompatibility issue with the engine and the stainless?? Always enjoy the content

[@SailLife]

Thanks :) There will be no issue having the bracket in stainless :)

[@maeilive]

I miss the old Mads that was funny..try to not stress to much. Give us bloopers😂😂

[@odonkers]

Excellent episode!

[@Rottingboards]

Looks like a wooden step coming out of the trailer is a must. I have really twisted an ankle using a block as a step. Love the channel.

[@Rottingboards]

The issue is you are so engrossed in your work that you kind of miss the step and it rolls. 😖

[@stevenr8606]

@Rottingboards you 👀 saw that, too 😮

[@SailLife]

Really all I need to do is to pick up another cinder block - I already have a plank I can use. I just keep forgetting 🙂

[@competitiverteam]

Was thinking the same thing

[@patraic5241]

I've got to say that cat looks so much more like a boat that will one day be back on the water compared to when you started. It's a remarkable transformation. And the best is yet to come. ☺

[@modmike4406]

I had the same issue so I called my friend who is an ASE certified mechanic. He removed a few studs for me in the past that had broken off flush to the engine block using the welded nut method. He suggested that since the bolt was not broken flush, that I use a brazing torch (a regular one may work also) to heat the bolt until it was glowing red hot, then cooling it by spraying it WD 40. Repeat at least 3 times or more as needed. The process will make the bolt expand then rapidly shrink which helps to break it free. Secondly, the lubricant in WD 40 gets sucked up into threads, helping things along. I know it sounds like one of those wonky internet hacks but I was shocked when the bolt unscrewed as if was never rusted.

[@shed52]

To remove the stud with a low profile, I often use a washer welded to the stud and then weld a nut to the washer and he nut. It does work.

[@iBradWatson]

I’ve seen people remove stuck bolts by welding a nut on and then melting crayon at the thread location. The wax flows into the threads and lubricates the threads. Lubricants and oils evaporate on the surface and don’t wick down into the joint. Worth a try.

[@stevenr8606]

👍🏻 also, drill a 'small' hole in the center of the broken bolt WILL release any pressure.

[@patrickradcliffe3837]

17:33 PLENTY of "Oh glorious sanding" and fiberglass to do for content. There's also PLENTY of interior work available "modifying that cabinet area/chart table"

[@HugoHugunin]

Q&A question: Besides sanding, what is your superpower? On a serious note, where will you be heading when she's done? Somehow I see Ava walking in the Galápagos Islands, giving us the history and biology of...well, just about everything from formation, geology, Darwin and Lonesome George - the last of his species, who was hatched in 1910 and died in 2012

[@markh3398]

Q and A video would be great.

[@chrishrabe4617]

Great video, better than a Q&A. Either way I’ll be tuning in. Great work as always, keep it up!

[@kevinmarrs758]

Love the Old English "D" cap. Go Tigers.

[@SailLife]

It was a gift from Ava’s parents - they’re from Detroit 🙂

[@DVanHamlin]

I was going to comment the same thing. Who knew Mads was such an awesome fashion accessorized! Haha! Go Tigers!

[@thetraveller869]

Absolutely the best way to remove seized bolts - particularly if they are steel or stainless steel and stuck in aluminium - is a spark eroder. One of them will make the bolt disappear and leave the hole untouched... Pan European motorcycle, cylinder head, exhaust stud. Assembled by Mr Honda in 1994 and not removed by me in 2017... 😆😆 Thanks to a tiny engineering works in the fair town of Swindon in Wiltshire who had the magic necessary I was able to replace the stud and eventually the steel exhaust headers with a stainless equivalent. Thoroughly recommended!

[@KiwiSkipper]

Q & A .. What software are you using for your CAD parts?

[@jonnooney7102]

Center punch the stuck heat exchanger bolt then drill out with a tiny bit, followed by progressively larger bits until you are close to getting into the female threads of the heat exchanger. (Close without going over like Bob Barker would say on The Price is Right ) Then try the welding trick again. Drilling the center of the bolt significantly relaxes everything and all the heat and vibration involved in all those operations will break the bond of corrosion in the threads. It's always worked for me and I've done a bunch on all kinds of salt abused boat stuff. Just be very careful on the last drill and keep checking your progress. A left hand drill bit will often spin the shell of the broken bolt out when it gets thin leaving you with pristine threads in the hole.

[@ikerstges]

exactly, also on all my motorcycles!.... if the snapped, stuck bolt still protrudes, file is flat first, so the centerpunch can be even more accurate. the drill does not have to reach the threads, just get as close as you feel you're going to get away with.

[@Jayr2374]

Great drive Mads !

[@SailLife]

Thank you! 🙂

[@Jnike8715]

Good move taking the heat exchanger to the machine shop.

[@ot0m0t0]

Mads, you are Danish, Im Croatian tonight its a match made in haven. Let the best team win. Hope you are waching as well. 😊

[@21indvendigegear]

Best of luck! Although I hope we'll win ;) ❤

[@nathanhotchkiss4842]

Idea for another video, 3D scan the inside of the boat. You can start designing things on the computer. Also, it very much may take more than 3 tries to weld the nut on the broken stud. Nice work this week, good video.

[@jamesallen712]

Q&A. Mads, be interested in hearing your thoughts of how to get the boat sorted enough to go back in the water and how you plan to tackle it in what priority.

[@--Valek--]

also try again with the nut on bolt, but take a small propane torch to the heat exchanger body and get it hot af. like hot enough to concern you, then smack the top of the bolt with a hammer before trying to turn it **smack straight down on nut not laterally**

[@bscott3211]

Tough but extremely heartfelt Q&A question... Jokul? I'm certain you miss him more than I do. Maybe a pupdate? Maybe even one day do a dedication video? Obviously I've been watching from the beginning. Also, I'm pissed you came to Kemah and hung out on Native Dancer directly behind me and I had no fricking clue... LOL!

[@MultiBmorgan]

excitement brewing here for cad and send cut send...... don't have anything I need to build (currently) but im looking into CAD programs and learning even prior to this awesome videos conclusion. thx MADS

[@grahammj1yt]

Love the eff you Yanmar, I'll make my own dam bracket!

[@KethKessel]

Godd to see you in a Detroit Tigers beanie on …hope to see you sailing up in Michigan one year.

[@theadventuresoffatcat1886]

I, too, use the thickness of stir sticks for measuring. Mine are metric, you know, like my crescent wrench.

[@MacDougallIndustries]

Mads, in addition to a QA video, how about a "call in" show? People could send in videos of projects they are working on and you could tell them what you think or would do, etc.? Many times I've been working on a project and have thought, "How would Mads approach this??"

[@jamesadams1064]

Great looking Detroit Tigers hat! I wonder who you got that from?

[@petitebiogeek]

Q&A (treat yourself to getting out of real time) let's have a lively discussion on what to name the "catamaran" "project boat"! Can Ava join virtually in the video?

[@andrewt1561]

For those stucks bolts, I have seen people heat the stuck bolts and use crayon or cnadle wax. The wax seeps into the threads and releases the stuck bolt/thread.

[@wallacegrommet9343]

Many Yammar washers, o-rings, and bushings are standard metric hardware. The 3GM 30f series parts manual often listed the sizes of these pieces

[@freakent]

Q&A: hi Mads, I was surprised to see you buy a couple of standard Yanmar/Hitatchi alternators. Did you consider fitting a couple of high output alternators like a Balmer?

[@iwonaawlasewicz5058]

Hello Mads: You are a hard-earned wealth of information so in your case a Q & A video is invaluable. I have two questions: 1) A few years ago you have installed a Lithuanian (or Estonian, sorry, can't remember) wind steering system on Athena. Would you recommend it? 2) Did you ever install a fuel polishing system on Athena? The one that sucks the fuel from the bottom of the tank and sends it back to the fuel tank? A penny for your thoughts. Thank you. Regards to Ava. Iwona

[@noelblack2029]

Dude just take a week off. We will miss you but I agree the Q&A’s aren’t so good and we will appreciate the great work you do and the quality of your sharing even more by having to wait a week.

[@Xalta_Sailor]

Add another coat or two of paint to the Yanmar air filter covers. They rust just from salt air. Or better yet put on a set of K&N washable after market ones. Lighter and no rusting surfaces.

[@topc9858]

Yanmar prices are absolutely crazy and you are smart to use alternative parts when possible.

[@robda7195]

Q&a how's the copper coat holding up on Athena? How are the donated/sponsored snubbers holding up?

[@donb4386]

Q&A I’m sure you’ve covered this before but I suffer from CRS (can’t remember sh*t). Could you take me through the products and technique you use to buff stainless back to it’s former glory. Thanks.

[@TheNugget360]

Q&A Do you have any ideas of what you might name the Catamaran? P.s. Captain Dumb Dumb is my hero 👌🏻

[@51rwyatt]

Q&A - I'd love for you to summarize the primary things the new boat will do for you/your family that Athena does not, whether performance or living space etc. As a bonus, are there are any significant downsides to the new boat compared to Athena?

[@mr.e7022]

Q and A..Did Bryan throw the engine parts out? Is there a port engine and a starboard engine to obtain counter rotating props?

[@JrR-fw5ph]

Go ahead “toot” your horn! Looks great! 👍

[@billkaroly]

When you are done refurbishing the old catamaran maybe look at converting that trailer to something else. It does already have a bow....

[@paulciampa]

after heating and after welding a nut on try using a crayon as your lubricant the wax penetrates better than sprays

[@dennisgraham8811]

Skip a week, I never watch Q&A's Also, I watch a ton of youtube and your productions is outstanding.

[@benstrand]

Q&A - can we get an update on Jokull? Will the catamaran be big enough for him to live on eventually when restored?

[@caseykandow87]

Love the Detroit Tigers winter hat!

[@rickhaass1133]

Giant bolty thingy = standoff. have fun

[@aserta]

18:14 QA on how you're adapting in the US??? 11:38 protip on cad stuff, don't bother with photos OR with any other dimension other than the critical ones (with the added dimension of thickness). On that bracket, for example, measure the round hole, draw it. Then, measure the distance from the hole to the spacing elongated hole, and draw a circle that's the same diameter as the width of the hole in that position. Then measure the width of the elongated hole and copy and move that circle to the other side. Unite them with the proper shape (if it's a curved bracket, you draw two tangent ellipses if it's flat, two tangent lines). For the tricky hole that's at 90, simply measure the diameter and in a second plane add the hole distanced by how much it is from the face, then use an unfold tool (which pretty much every cad system has, either native or as an addon). Then, just add the "meat" around and that's it. No pictures, and all the verbiage above takes less than 3 minutes. Pictures will only slow you down with import, scaling, bla, bla, bla. Doing it from scratch also helps you go crutchless faster.

[@stevenr8606]

🤔 good price on the alternator tensioner bracket. 💡 However, you may have forgotten the additional STORAGE FEE CHARGE, as I'm sure you won't/can't sell them all... instantly. 😊

[@mr.e7022]

What? Are they renting vault space at Fort Knox?

[@colinwinters6140]

Just a thought. Abom 79 is a KZbin creator and machinist he has a shop somewhere around Pensacola I believe may be a good collab.

[@paulschendeler1965]

Q & A - Hi Mads, you used AC360 in this video. It is a complex program to learn. What advice would you have to help someone who has no experience in CAD to learn how to use it? Thank you for all your wonderful videos. I'm a long time follower and I look forward to watching you every week.

[@glened1]

Q&A: Why are the slots for the hinges longer than the hinges themselves? Looks like a big gap at the end, no? Love ya, Mads!

[@iwoodie]

Aren't you afraid that the RVS316 version of the alternator holder you designed is more weak than steal?? And second question: what is your thought about all these weak build French catamarans?

[@Mechone11]

As Millwright I fabricated my own bracket and tensioner

[@SailLife]

That makes sense 🙂

[@bigslick75093]

Q&A: I’ve been an off and on viewer of your videos for 4-5 years now, but missed the ones as to why you spent all those years restoring Athena in order to sail around the world, to instead now spend even more years on rebuilding the CAT you have now?

[@mr.e7022]

Me think Mads is an engineer, they build and fix things.

[@spinyheghog]

Q/A how has the 3d print journey gone and what do you think of using cad and services like sendcut send

[@Drew-de7ey]

Maybe that wider engine hose clamp thingmy goes on the outer end of that funny looking alternator pivot bolt.... ?

[@flutetubamorg]

Tramp ramp is definitely a big step away from "derelict"!

[@jeannettethevan1458]

Hi ! Q&A 😉

[@yankepilot]

After polishing your chrome hardware use some shark hide so it will retain its shine for a year without any further maintenance.

[@kaufmanjeffreys]

Q and A is fine.. when do you anticipate moving this to the next dry dock to get closer to water?

[@georgeluckert5430]

You are an example of patience.

[@richardheuberger6154]

Q&A Athena Hi Mads ones upon the time you used two different isolations under the deck 🙈 do you have notisen any difference in performance? Do remember a big difference in prise🤔 as usual a god video. 🇸🇪

[@MC_MMV]

Q&A: how did you first get introduced to sailing?

[@peterasquith6942]

That’s Slack Lazy Ass LEOPARD with the dry glass spots.

[@SailLife]

Why don’t you tell us how you really feel? 😉🙂 Yes, it’s completely nuts for something like that to get past QA. Very embarrassing for them!

[@bobnielsen2787]

316 might be a bit soft for a bracket >> W 44 would work well >>>> great work and skills Mads

[@GoofieNewfie69]

Q & A Yanmar, Volvo and a couple others are companies to avoid unless you're rich. Kubota (Beta, Nanni) re much more cost effective options. Parts are also much more affordable Have you looked into a repower? There is a lot of value in complete running Yanmars to offset buying new.

[@johnmooney9444]

You could use one of your Athena videos as a buffer.

[@stijndeklerk]

A induction heat bolt removal tool could well do the trixk. They cost about 150,- USD or maybe you can borrow one somewhere..

[@DanandJazz]

Do the Q&A!

[@cgeorge6250]

I have learned so much from your videos. Thank you for being so willing to share.

[@SailLife]

I'm glad you've found them helpful! 🙂

[@dannyjones3840]

Mads, remember after applying your poly putty in the cold- cardboard box and small heater for the win 😂

[@asciiavatar]

I'm not sure why, but at 14:38 the sound of the buffing wheel combined with the music made me laugh

[@Havoc58594]

What about a boat tour? See the complete before footage 🥰

[@tom18181]

Q&A Hi there. How much solar do you think you might get on it and what kind of Victron inverter do you think you will need for your cat?

[@patrickscarr]

Q&A How is your dog? Will you get another one?

[@BobStienke]

Q&A Hi Mads, have you two selected the cat’s new name yet? Thanks, Bob

[@yankepilot]

MADS, from now on….when you put on your sweaters on camera…you have to say…won’t you be my neighbor. It’s a line from Mr. Roger’s from Sesame Street!🤣🤣🤣

[@Glenbard4]

Q&A: Mads, have you and Ava started talking about what you’ll name the catamaran?

[@CharlesFlahertyB]

Q & A any concerns about leaving the spiffy tramp ramp in the FL sun for the next year or so?

[@megagrizwald]

Have a tour of the yard you are in

[@haydenwatson7987]

I avoid buying OEM parts anytime I can. The missing o-rings, you can get from either Ace or any other good hardware store. The pin for the latch would be a roll-pin and I get them in SS at my Ace but you might need to go to a chandlery. Are your new alternators from Yanmar? They are a commodity product and there are much better-quality ones at a lower price elsewhere. Last year, I purchased an externally regulated 250A Denso Hairpin large frame alternator with tach tap from Tucson Alternator Exhange which cost less than $400 and performs flawlessly with the Zeus regulator.

[@SailLife]

It's on purpose I've kept the 12V alternators stock. I'll use a 48V (around 5kW) alternator for the house bank. More on that in an upcoming video :)

[@AndyUK-Corrival]

That’s a lot of effort and time for a bracket that could have been made in no time.

[@claudehopper9813]

Mads , you could make a blooper video of things that didn't quite make the cut ?

[@delwinchafe976]

Take a break Mads !!!

[@Jayr2374]

Looks like bracket might mount on upper stud .
