- In this video I install a couple of 240V battery chargers into the trawler to allow me to charge off the generator or shore power when it is available.
This a charger similar to the ones I used, but not the same brand www.amazon.com/dp/B00F5EBTGA/...

I wanted to click 50 likes to that one!!
I think the more consistent but shorter (10-20min) videos is exactly what the algorithm wants as well as it being more convenient for you Stu. Comments also affect how the video does people, so don't be shy!
Opening music,thats jazz,with fish.
I wanted to hang my charger sideways, instructions said "no".
Thanks again for taking us along!
It looks like a pleasure to finally work in a suuuuper clean bilge area.. Nice work Stu!
It is much nicer to be down there now!
Awesome install Stu,those ban marie trays fitted just a treat and will last a long time.So happy for this mid week upload as it cuts down having to wait for much anticipated weekly uploads.
Thanks David!
Just wondering, how does someone give a thumbs down here? What’s to dislike? Excellent content! Thank you.
“Everything is upside down in Australia”? Best explanation I can think of.
Thanks mate!
I’ve been watching this since you got the boat, you’re resourceful, honest and persistent. Keep it up, maybe I’ll come down under to see the finished product. Never been there and it’s not very far from my retirement country.
Probably New Zealanders.
Down is the exact same good interaction as an up... What hurts is the VAST majority that doesn't click up OR down.
Great information.
Love watching someone work.
Great work man ! Give the puppy a pat for me . Oh , don't forget a few frosty cold ones when ya get home !
I will, and won't. ;)
Fresh single mullet fillets packed in salt wrapped firmly in a few newspaper sheets and freeze overnight remove sheets brush off salt repeat a couple times makes it a lot tougher it will stay on the hook better but be as fresh as day you bought it in both looks and smell keep it in a white foam box in a cool shady spot will last all day
keep up the awesome work stu love it and learning heaps cheers kev
Good stuff Stu, coming together nicely mate👍🏴
You should have the wires facing downward on the chargers. So that moisture and water dont pool up and run down the wires into the unit.
I was going to say the same thing. He needs to install drip loops.
Second the recommendation with a service loop on the wire. At least 4" of wire running straight down before it makes a turn back up. Do what you can to keep moisture/condensation moving away from the electronicals.
ditto this
They are sealed units also ignition protected.
@@SkypowerwithKarl Karl Jensen Ip67 yeah, ~30min underwater. Those gaskets don't look too reassuring either. Having the wires facing down is just an extra precaution, making sure nothing gets in. But at the same time, giving condensation somewhere to get out.
Stu, you don’t want to mount the sea water strainer above the engine sea water pump. It will be difficult for the pump to suck up sea water in that position, and you will end up with overheating problems. Detroit diesels are very susceptible to damage from overheating.
Mount the strainer low in the bilge.
Second that every boat I've been on in Alaska and Washington that have strainers are mount as low as possible:)
Yes, I guess I might have to sacrifice ease of access for better normal operation. It certainly makes sense.
You might consider mounting it in the rear lazarette compartment for ease of access. It doesn't have to be mounted in the engine bay. I agree with keeping it at water level to reduce difficulty priming the cooling pump.
We used to use a 'ballast box' (I think that's what it's called) to 'start' big industrial lights.Maybe an electrician could advise. Problems sound similar, they require big hit initially and then settle. Good luck, love your work.
Thanks mate, I'll look into that.
Another great video Stu thanks for sharing it. The trawler is really coming along!
The kitchen tubs were a great find. Thought though, mount foam rubber under the lips of them. The vibrations will wear out the metal and paint from where they sit.
Yes, definitely need to do something re the metal on metal thing.
Very jealous!!! You've got quite a nice set up going there. It's great seeing the boat moving with the swell.👍👍👍👍👍
Thanks mate. I can't wait to see the boat moving under it's own steam now.
Liking the new format with more posts!
Probably too late now but set a table saw for 2/3 the sheet thickness then cut down each support line center the board will now fold down those lines allowing you to get it in and you can fold a side back over when you want to yet still act like a whole sheet when lying flat.
Great progress again, but one worry, you are going to attach the raw water hoses before fitting the engine because it's difficult to get to after. Having had a couple of incidents where it was necessary to close the seacock in an emergency, you may want to think of making a mechanism to attach to the side wall of the engine box for such an event. You just never know out at sea.
Loving the series. 🇮🇪
Given where it is positioned, it is very tempting to go to a remove controlled seacock of some description for sure.
It’s so sweet watching you cruising down the home straight whew that hull repair was so radical
It is getting close now!
Great idea the stainless trays for storage but definitely put some rubber or anti-vibration strips in. They will rattle and wear badly in a short time. Love your work mate. Cheers from Bribie Island QLD
Yeah, definitely need a raised rubber strip to both help lock them in and stop vibration.
very good vid Stu , having Eddie onboard makes it an excellent vid !!!!! keep up the good work
Thanks Matt!
C'mon man it's like midnight here...was just trying going to bed. Alright, I'll watch.)))
its like 2am for me XD insomnia is a bitch
gday from up cessnock stu great to see the ol girl making a come back bit by bit
Fine job on those dual chargers. I really enjoy the updates on the boat. It’s gonna make you a super fine ride!!!!
Good work, love watching the electrical work being done properly. I am learning so much and will apply it to my own Hawkesbury River cruisers. Keep up the good work Stu.
In my experience, it doesn't take much to clutter your boat and when its cluttered, it makes it less attractive to jump on the next time.
Whenever ive done a clean up, its amazing how much it affects the way i feel about my boat, even though its my boats fault.
Clean boat, happy skipper.
Things seem to be moving along -- a little here, a little there, a little fuzzy helper to help keep you on-task. Great update before I head off to work. Many thanks, Stu.
Getting there Randy, will be running soon!
Essential items to be left on boat: 1970s banana chair, Cooper's x 6.
Nothing like a banana chair after a long dive
6 cartons ?
Absolutely!
Those clouds look ominous best take cover
A peak-load capacitor will hold the start up draw for your plasma... matching and balancing the power demand will be easy for you. I like the multiple leads on the battery chargers... not being in parallel affords you a redundant system and the ability to monitor each battery independently is a bonus. Really enjoy the frequent posts!
Excellent vid Stu! Things are marching along nicely! :-)
Thanks Chris!
I really love that trawler. You’re doing a great job and things are coming together well. Thanks for bringing us along!
Thanks Jay!
O great something to watch on my mid-watch ... cool mellow night for the ole Dangar Marine...
Cheers, Stu, another great video full of projects!
If you need someone to just stand and watch holding a bourbon telling you your doing it wrong. I'm your man.
Hey Stu, I haven’t had allot of experience with Plasma cutters, but I’ve seen many inverter welders (essentially the same machine)ruined on minesites due to being ran off a smaller generator. The general consensus from Boilermakers is that 8 Kva is the minimum size so as to not damage your machine and have smooth operation.
This article from weldclass essentially says the same thing - www.weldclass.com.au/blog/47-using-generators-to-power-inverter-welders-your-questions-answered
So glad that you make these vids mate, thanks,
Glenno
Yes yes yes timber boat will be awsome!!
You may want to mount the sea strainer so that the cleaning opening is just above the waterline. Much easier for the pump to prime.
Yeah, I think I might have to mount it a bit lower which is going to make it a pain to clean but it is more important that it works properly.
You may be surprised at how little you may need to access it. Unless you sail through a mat of vegetation, the only thing you will find in it are beads of styrofoam. If the strainer isn’t overwhelmed, most organic matter decays and turbulence grinds it down into such small pieces it passes through.
One solution to reduce starting load is to wind a coil of say 30M of number 12 wire on a 5cm form as a starting point and see if it helps. Also, running power thru a long cord may also provide the sag needed for startup.
Interesting, I'll give it a try.
Hi Stu, like someone else said, the chargers would be better the other way up with the cables coming out the bottom to prevent water/damp ingress. You could then also use the slack cable below the chargers to form a cable drip loop. Looking good though, really like those chargers, neat idea 👍
Yes, given the screw holes will be the same I may well flip them over to be safe.
Yes awesome video! Great work my friend! She's really coming together. Brandon - California
It's all coming along nicely Stu :-) Nice to catch up with the new updates mate :-)
Love the dig at us in the Northern Hemisphere Stu. As we fast approach Winter your fishing comment about the whispy cloud was really below the belt. As always I enjoy your vlogs.
I'll make it up to you with a free fishing trip if you fly south. :)
@@DangarMarine Haha. Ok...I forgive you. :-)
Some clouds... hahahahahahaha. Great post Stu.
I was scared! ;)
@@DangarMarine Too funny. Keep up the great work Stu, loads of people are enjoying your channel. Cheers Damo.
Stu try a couple of compressor run capacitors on the output that feeds the plasma cutter should help with the current draw on initial arc 😎
in general if you have a tool or motor with a high amperage start load and a lower amp usage load you can use a capacitor to make the difference on start up
Your assistant, Eddie isn't much help! LOL! Anyhow, I'm really enjoying watching this old boat being transformed, excellent work Stu!! Also loved the videos of your trip to my home, the US. I wish I could've made the meet up in Hampton Virginia, I live 2 1/2hours drive from there. Maybe one day I'll get to go to Australia, one of the top 10 places I want to visit before I die. I met some good soldiers from your country years ago during the Gulf War when I was in the US Army. Good, tough soldiers. Met three here in the states as well while I was still serving back then, they were attending a US military school at Fort Benning in Georgia, all I can say about that is DAMN you guys can drink like a fish!! LMAO>
I hope you do get to visit Australia one day! :)
wow stu your comin on with the boat well done you even more so your summer is on its way so my son tells me in Melbourne great vid stu
Nice catch up Stu. We have used a genny for some outdoor gigs for our PA and had a lamp plugged in to pre load it. May be that would work for the plasma tool.
Thanks Straight Ahead
Great update and Perfect weather too Keep em coming
Thanks mate!
Thanks for the video.
You can try using an inductive load on the generator when using the plasma cutter, a small 1hp motor running without a load should help, even a large grinder running.
I'll give it a shot!
Nice one Stu, I deffo agree with reducing the clutter, it makes life so much easier and of course it reduces the splash factor for falling overboard. Got to say, your wire runs are looking better than your mates but try to avoid coiling any of the runs, I found it turns them into an induction coil and even on 12v they can get pretty hot.
Thanks Mate. I too was wondering about coiling up the excess. I've been trying to find the definitive answer on how much of an issue that is and it seems that as well as the amount of current flowing, the geometry of the coil is also very important. Here, a lose oblong-shaped seems to be working in my favour en.wikipedia.org/wiki/Inductor
Hey, Stu, that's pretty clever putting a little gray frosting in the beard... makes you look more like a seasoned sailor! Let it grow a bit longer, then get a parrot and wear an eye patch, - they'll move out of your way. 😉
Eye patch is on order, should be here in a few days. ;)
That about as neat as a haystack 😎
Stu you mentioned about your cuter not having enough power from your generator to arc what you can do is put an ac capacitor across the plug for the cuter this doubles the voltage and makes the unit work easier. Just make share your unit can handle the voltage bump.
Eddie isn't getting the recognition he deserves. The channel title should be, "Eddie, with Dangar Marine."
It should be. :)
She is looking good.Cheers from Western Canada.
Thanks Bob.
The generator problem is most likely the electronics not liking the generator output. Plug a decent size motor into the generator at the same time and see if it helps. Sounds odd but there is science to it
I'll give it a try.
I've had starting issues with equipment running on generators as well. I found the solution that worked for me was to tweek the governer screw to run a bit faster. This increases the voltage and gives troublesome gadgets some extra beans.
It's not a bad idea to put a volt metre on every now and then, because those screws can loosen off with vibration.
Of course, some electronic stuff can get the heeby jeebies if they're not fed the right diet.
Ken Godfrey was just about to say what you just said ken! Exactly the frequency will be changed by the extra speed of the generator and can cause far more damage if not careful than low voltage can. Also keep in mind those little brush style generators produce very dirty power it’s hard on eletronics and power tools anyway.
Of course I bow down to what is obviously far greater intellect. But I did point out that my suggestion was not without pitfalls.
Given that the output of this type of generator is dependent on constant revs, both the voltage and frequency are affected.
After discovering that my cure worked for me, I took the opportunity to test the output of a number of portable generators being used by my clients. Many of them were under performing.
Warren Neeves hahaha don’t worry about it just didn’t want you to blow anything up. But like you said you might actually just be bringing them up to where they need to be if they were underperforming.
For the plasma cutter, try plugging in a blender and fire up the cutter with that running.
And you could make margaritas while your at it
Or a grinder running but with no load. I think you are more likely to have that in a boat. The plasma cutter might not like the "noisy" current from the generator and running an electric motor off it will smooth it out a bit
@@erolaattori2317 Maybe a mounted bench grinder (cheap and handy) - the idea of a handheld grinder flopping about and taking off on its own doesn't bear thinking about.
Liking these more frequent vids stu. You should look into cable tie mounts or zip ties you may call them? Available in plastic and stainless. It's a good way to tidy bunches of cables.
Eddie is awesome!
Hi Stu, Was just thinking when you fill your tanks with Diesel add some Biocide. This will stop any bacteria growth since they have been sitting for a while. You don’t want Black diesel and it happens fast , Cheers Mick
Yes, well worth doing.
Can not wait for the timber trawler as one of these is what I am thinking of getting
Mick morgan Ireland
Those pans are called hotel pans. They come in fractional sizes, whole, 1/2, 1/3 etc. and in depths usually 2", 4", 6". Can't tell for sure but it looks like the ones you have a 4" 1/4 pans.
Thanks for sharing
Those are excellent “smart chargers”. The individual outputs are primarily for batteries smaller than 4Ds. They were primarily designed for charging multiple batteries that you would find in a trolling motor set up. Typically charging individual 12 batteries that are in series 24, 36 volts or 24 volts and one starting battery. To attempt to charge a 4D or 8D with a single lead will result with a battery that doesn’t reach a full charge or will take days because of the huge internal resistance of large batteries. If the instructions allow, perhaps you can parallel the leads to one battery. I highly recommend Vmax 8D AGMs. The minimum I charge them with 20 amps per battery and preferably 45 amps or 90 amps with two in parallel. Hitting batteries hard wakes up the chemistry and as long as it is not over charged they can last 8 to 10 years. Always with a smart (intelligent) charger or your killing your batteries. One last thing, when the batteries read 12 volts (with no load) it’s 100% depleted, stop and charge. If you charge when it’s only 75% depleted, you’ll get more cycles and life.
I like the way those Vmax 8D AGM batteries have the dual terminals too. They look very good!
Funny thing, a year later they seemed stronger. Stay away from the Chinese batteries, cheaper and you don’t even get what you paid for. Black plastic case with white writing, numerous brands from the same factory. I’ve replaced lots of these p.o.s’s
Stu, if you put in a 15amp shore power inlet to feed those charges make sure you do it to the Australian standards there's one for boats as well as AS 3000 the wiring rules because it you ever want to use the boat commercially it will have to comply, also if the boat was to ever sink or catch fire while plugged in at the dock and the 240v installation is not to standard your insurance company will walk away. Also make sure you research galvanic isolators as well they go in the earth cable coming in from shore power to stop stray currents from eating your anodes then hull to quickly while plugged in, its worse here in Australia with our M.E.N system multiple earthed neutral system, it's basically path of least resistance and all that as salt water is a great conductor.
Yes, there does seem to be a lot to get right when it comes to connecting anything to shore power. I think I was given a galvanic isolator ages ago by a guy with a timber boat, I must dig it out and learn more about it!
When you rip the plastic board, cut it on an angle, say 30o so they can mate and put stops on the edges so the two halves don't slide away from each other.
Good tip!
those pans that are stainless steel are called Hote Pans, they are used on serving lines. They come in different lengths
and depth, always the same width as far as I know. check with a restaurant supply house.
We did have a couple of different sizes, I'll have to dig them out.
Good work
And just like that it was finished .... it felt like 5 minutes 😢 .... keep it up Stu still really enjoying every episode
Thanks Nick!
" Everything has gone pear shaped" never herd that one before. If you are going to mount the sea strainer that high I hope you have a bad ass water pump.
Fin another is "Everything has gone tits up"
Unless the (poor access) seacock is shut off, opening the strainer will cause all the prime to drain, and if you try and suck air with an impeller pump you're going to have a bad day. I'd be thinking of a flush metal hatch in the deck to access that area.
the mental staying power these non-landlubbers have is really inspiring for me. just saying.
Try hooking up an inductive load to the generator an ac motor works well like a blender or fan.
Will give it a go.
You might try running a ground wire from your genset,to anyplace convenient since it's a steel boat.I'm thinking the surge current when you fire up your plasma cutter may play into this as well. Just a thought.
I should look into that. I need to sit down and think about the various grounds on the boat.
In regards to the plasma cutter, I would try running a motor or some other inductive load then strike the arc, a motor with a flywheel will act like an accumulator of sorts when the initial load is placed on the generator and help it overcome that initial starting load.
I'll give it a shot.
See if you can manually make the generator run at full throttle all the times instead of idling when under no load. Idk if that will do anything to the electric components in the generator but maybe worth a shot. Sounds like the ultimate solution would be a welder generator that you can portably weld from and use as a 120/240 generator but definitely not cheap.. might be able to find one used. Great videos Stu love the channel keep it up!
Hurry up. Great job.
Make some locater pins (2 min.) and keep them w your bolts no measuring just paint the point or a light tap and drill your marks
Most gen sets have idle up on them. But a plasma uses plasma air arc to cut so it may not be getting the initial amperage to start the plasma process. It also just may be it doesnt like the signal from genset so a inductive motor like a blender running b4 arcing may clean up the sign wave and work. Worth a shot. Oxy/acet may be a safer/easier bet on a boat. Obviously stored correctly not to make a bomb : )
I'll try adding an inductive motor, it's certainly worth a shot.
Stayed up late to see if Stu would post a new video, and in 6 minutes someone already commented.
I have a Bosch angle grinder with a soft start. So it won’t work on a generator. Plug a regular high amp grinder into your genset and turn it on before turning on the plasma cutter.
I'll give it a shot.
Great video Stu, I believe the welder is an inductive load. The initial arc is most likely overeating the generators maximum rated output. I'm guessing the generator is a 6.5hp with 2.2kva alternator on it. You may need a 3.4kva or higher.
I see lots of guys stating video length .
Longer the better in my opinion
Highly entertaining enjoyable and worth watching
Who cares about algorithms and ratings
good one Stew..gees I like the bain marie tray idea mate..good recycling effort there..I especially like those two shiny blue kingchrome boxes mate..I hope they are fully stocked with all the latest matching spanners..Hope you have big padlocks for the blue girl though..wouldn't last 5 mins at 1770 I tell you..
Thanks mate. It is good to have the tools onboard now and fortunately it is a pretty safe area around here.
Refraceing the plasma cutter:: Oddly enuff sometimes when you put a long extension cord on it it works just make sure the cord is over sized... I use a 10 gauge.. not sayen it's right just sayen it works...
I'll give it a try!
@@DangarMarine Generators don't handle inductive loads very well, and a plasma cutter is almost completely inductive load. You may find plugging in a resistive load with the plasma cutter (something like a 150W-200W halogen worklight - not LED) will help the generator cope with the inductive load of the plasma cutter.
Great video as usual :)
Thanks Chris!
Something to make me happy
You ought to rig a hammock over the afterdeck for those job well done beer moments!
I like your thinking Nathan!
I literally laughed out loud when I saw the banana chair. Just pictured stu, covered in dirt with a beer surrounded by work kicking his feet him. Thanks for the videos stu.
A man has to have priorities. ;)
You may be able to deal with the the plasma initial draw of current with a bank of capacitors.
What does that even mean?
This might help for fatigue in the plastic mounting boards. Have you thought about putting large washers on the head of the mounting bolt to spread the load of vibration fatigue in the plastic? Your idea is ok in a sailing boat. As soon as you have your engine running you have to think of the high-frequency vibration which is hard to prevent even with rubber dampers and shocks on the engine.
Yes, I was thinking the washers were in the same tray as the bolts but they weren't. I'll have to find them!
Lazing about on the old school banana chair is the go! Or is that taking the banana myth to the next level?
I like to push my luck. ;)
The 15-20 min format 2/3 time per week is very popular for Engineering/Restoration vids.
Have you given an thought to fitting a PTO to the engine before it gets remounted, I think that small crane won't be man enough once you start diving/salvage work with her. The option to go hydraulic at a later date would be priceless compared to the cost of the PTO now.
Yes, I have been looking at getting a PTO for it. Hydraulics would be very handy.
