- Aluminum Pipe Bending, Heat Bending, HTP Propulse 200 Aluminum Welding, Miller Spoolgun Aluminum Welding, Plasma Cutting and Saw Cutting Aluminum. Everything we love about working with steel but with no sparks. Josh Barton wanted practice welding aluminum so he came back in for ten days, and Greg Stein spent his weekend off from welding school to also get some aluminum time. And the Love Me Tender now has all of its big pieces firmly fused together.

This Project is turning-out much much more impressive than I initially thought - looking real nice Doug.
Hi Doug. A simple trick when bending alluminium with heat is instead of using a torch to heat it while bending where you have no indication of the temp. You just light the acetylene and coat the ally where you want the bend with a good layer of soot , So its nice and black. Then use the oxy and acetylene to heat it until all the soot has gone. This anneals it and it will bend nice and easy , then it age hardens somewhat back to how it was before.
Great build. I'm building a 10' aluminum mini jet boat, I learned a few tricks from you just by watching this video. Thank you keep it up!
Cool. Send us a photo.
I'm surprised how quick this is coming together!
I look forward to see this out on the water during sea trials. With that jet drive it will leave a nice phosphorescence trail at night.
It looks really good Doug. I’m not just saying that because I’ve been watching since the first sheets of steel were tilted up and I’m a huge fan, I really like how it’s turning out.
That's becoming one badass sled, Doug.
Can't wait to see it on the water :-)
I consider myself more of a dobbe than a welder... so I'd probably fit right in ;-) I've built smaller projects like a tank inverter which inverts 120 gal propane tanks to remove the fuel, built a large torch to burn off 30,000 gallon propane tanks, even built the hardware for a door that went to the Hanoi Hilton. But wouldn't dream of tackling a project like this!!! Well done Sir :-)
Great job on the boat. Thanks for sharing my photo of my water tank at 24:02!
I really like to see all the progress, nicely done sir's! 👍
A cacophony of sounds! That's what progress sounds like! Thanks for posting!
.
Man that tender is one beautiful thing. I would love to take a ride in it.
way to go looking good, it well be so cool to see it in the water...
What an inspiration , this guy is a genius
Not genius, just determined and willing to listen to ideas from our crew.
Learn something everyday, never realized Ally could be shrunk the same as steel , now I know , cheers
I am sure everyone got a chuckle at the end that allowed their Jaws like mine to reattach! Watching a great video about production and fabrication on the fly, be it Ala SV Seeker and the gang! That just goes to show you all that is learned,, by apply ones self!! I am getting melon coli thinking of my Old man doing the same with me! I must plan to Visit!
That boat came along fast! great work.
That looks like a lot of fun!
It so nice to see you guys on a roll :-)))👍
Some serious ‘swarming’ going on.
Wonderful.
For that vinyl you should really look at old billboards. I'm using as fabric for some motorcycle luggage and I think it'd be perfect for your application. Crazy durable cheap green and I think it'd work well for y'all!
I gotta admit I follow chucky, Jody and Bob moffit as well as have been looking at all the things Doug has been building and I sure admire your tenacity! I have been welding some aluminum docks at work and using a miller 185 with a 150 amp spool gun and .035 5356 wire am struggling to weld 1/4 without a preheat ... a lot of preheat ! if you guys had any tips I would love it! Weld on Wild Men!!
I realize Mr. Doug Jackson would have times of frustration, but i have watched the ongoing build of his boat for years and haven't never seen him curse & violently outburst. Amazing man, who will be an Awesome Captain
Anybody who doesn’t swear or have outbursts is not human, and not someone I’d want to be around. Life has it’s frustrations...sometimes you need to let it out.
:) awesome work everyone! I hope Bart organizing the bus makes up for him calling your weight into question lol. Cheers guys have a great week. Bryan.
Woaw ! Con grats on the Tender ! That was damn fast you guys got that welded toget her !
Bart is a competent and dedicated crew member.
Bart is Awesome. He has the best attitude of anyone I have ever met.
Bart the old fart is awesome
So much accomplished in a short period of time. Well done! It's looking good!
and you would know all about that :)
You prolly dont give a damn but does someone know of a method to get back into an Instagram account?
I stupidly forgot my login password. I love any assistance you can offer me.
@Carl Emory Instablaster ;)
Great work doug! Looks great!
I really enjoy the videos. Keep up the good work.
Here's a little trick with aluminum if you want to anneal it hit it with a sooty flame and then heat it with your normal flame when the soot disappears its annealed.
Dang! Been told that and forgot all about it.
Exactly, works like a charm.
David Kirkham has a video on him repairing a fender on one of his Cobra's that shows and explains this method....th-cam.com/video/9moYO-WWhaQ/w-d-xo.html
Hey Doug, Use the SOOT technique! I didnt get to watch this until today. Maybe its too late, Maybe someone mentioned it already I dont know BUT is you go over your aluminum piece with acetylene soot then proceed to heat it when the soot burns off the aluminum is in its malleable state. Very good indicator. I use this technique on old aluminum boats. ( I have a video on it)
Coming along nicely
That’s looking good, smart design!
The boat looks great
Fantastically coming along .. My first though was that the "Swim platform" could also be utilised for fuel storage.
Yes, but we need buoyancy there so she has a chance to sit flat even when flooded.
19:50 a (vertical) bandsaw might come in handy. I'm loving the progress!
At least this boat isn't taking 5+ years :P Love the videos!!
Don't be scared of the big projects. You can spend 10 years and have squat to show for it really easily.
Nice, i particularly like the handrails for lashing things to. That will be useful.
I'm not crazy about the rivets that will hold on the vinyl.. Rivets stretch.. bolts with inserts probably wouldn't be a whole lot more expensive...
Fair winds and thanks for the video :)
can't wait to see it on the water!! it is going to be truly awesome! "And at least on the bottom I wouldn't have grind the welds! because it will increase the toughness and extend the life of the boat!
Looks Like FUNNNNN!!!!!!! Thanks for sharing your day. Best Wishes n Blessings. Keith Noneya
There's a very large market for that boat here in the United States of America. We have plenty of creeks, rivers, lakes and oceans.
I love the experimentation that you do, and the solutions that you get out of it. It saves so much time when I get going on stuff having seen your tests. Also sometimes I feel like the SV Seeker project embodies the "Fuck It, We'll Do It Live!" philosophy in the best way possible. And I love it. Cheers! Can't wait for the next video.
keep up the hard work bud ! looking good
Great episode. Keep it up.
Man, I love every video you've made! I only wish I hadn't found your channel during midterms haha. This channel is significantly better than any show you could find on TV. Anyone that has completed any large DIY project can appreciate how amazing it is that you've done all of this in a matter of 7-8 years. Thanks for the inspiration and entertainment!
One question: Are you planning on doubling or tripling the plate on your forward attachment point/eyelet? I'm always hesitant to make any comments on other people's design, but I had an aluminium tow hook made of a similar gauge on small import coupe that cracked/split while moving it to a different parking spot in the driveway (low speed and little acceleration). Just thought I'd throw it out there. Keep up the awesome work and thank you for the great videos👍. I might have to stop by on my next trip to Texas and contribute a day or two of labor.
I'm not planning on anything more on the tow hook. It's 3/8" thick and welded in over a foot on both sides. It's the lift points that will get most of our attention. Especially the aft point that will carry most of the weight. Now please get back to your studies. :)
Now I remember why I don't make knee-jerk comments on people's fabrication videos. You've spent countless hours on each design and I watched weeks of work compressed into a 20 minute video lol. Keep up the great work and excellent vlogs!
tender looks great
Good job if you want to bend pipe fill it with sand tape the ends perfect bend every time
Nice job guys big thumbs up 👍
To shrink metal, heat the centre area then cool with water progressively repeating the process outward as required. I hope this helps.
If you can still find a bar of LUX soap rub it on the Aluminum when heating it up to bend or annealing it and when it turns black or starts to burn stop as its about to melt the job, you are doing a great job.
Great job guys well done!
Hi Doug instead of pop riveting the sheeting to the side plating would you consider using a Sail track to slide the sheeting into so it is supported for it's full length. We have used this system on canopies and find it stops water coming in as well and it makes changing the cover very easy also it would allow you to shape the foam to whatever shape you wanted. The sail track is available in different sizes and in aluminum so it can be welded to the underside of the frame. The top lashings sounds good.
Thats and interesting idea.
If it'll go round corners...
If you trim the track back so to reduce the flat width the sail track will take a gradual bend with no trouble. It can be cut using Doug's rip saw he has been using to cut the aluminum sheets.
I love this build, it looks like a fun project
4:27 beautiful sunset as usual sir...
Hey Mate, this is coming along nice.
Only found it thanks to ChuckE2009.
Just a little tip if you didn't know, when annealing alloy, if you hit it with just the acetylene flame first and blacken it with carbon, then with a rosebud torch tip, burn the carbon off, it will be perfectly annealed and should naturally harden with age or as you work it.
good luck with the build, just a bit far for me to come and help out seems I'm in Australia, but I'll try and drop you some coin soon.
Or you could shot it with an IR thermometer gun and find out tje exact temp for annealing for that alloy and do it right. Too much will soften it and after a little while of smacking waves it will crack there.
Thanks for the great video!
Looking good!
At 13:26 Bart is Slim Pickens ! A real t shirt worthy moment !
I like your stuff.. I'm a boat builder / sailor / racer / cruiser. I can't wait to see how the tender performs. I have my own ideas because I love boat design. I've always tried to visualize how a hull works and why... I have a feeling your tender will work fine once it's moving / at speed but I'm thinking that initial push to get moving might be splashy in a seaway. The nice sharp vee will handle approaching waves well, but It's pretty far back from the bow. (I feel like you may suffer from a lack of bow buoyancy at low speeds). Not that the bow will go under, but I'd love to see a nice 45 degree or better angle on that bow plate (top deck to lower deck) to help it climb that first wave or two. I built an 11' wood flat bottom runabout that went 83 mph with me in it. I know that's not what your interested in (speed) but I have a sailboat that goes 5 mph too.. lol So we can talk! Love your channel. SV Sea Yawl Later !!
another great video!!!
I once had to take a float plane, that damaged its floats badly out of the bush. Their was no way to rapir it properly. So I patched the two step compartment, with light aluminum and pop rivets,Just to get the shape, and pored in foam, made for boats flotation, into the float compartments, put the lids on while the foam expanded. I thought you could do the same in the back part off your jet boat, that way you know its full of foam. Get 5 gallons of A and 5 of B and mix the two together, and poor it in a hole . Make small batch and that way it will be cool and dens, and not light and full of air. the weld the holes shut. Sorry I forgot the name of it. I did this more then 30 years ago.
Cool. Love back country repairs. That would work, but I already have a chuck of EPS and we dont have to deal with the sticky mess.
And that pour in foam and all foam sooner or later absorb water, whatever the maker say they ALL absorb water eventually . You have been warned! Oh....40 years of dealing with old boats......that's how I know.......Warren.
I had an Idea for around the boat, you could get some large diameter water pipe out of PVC like they bury in the road for the mains. Then fix it to the boat with threaded bar and bolts, and fill it with expanding foam for buoyancy. The boat would have a durable buffer, and floatation, and look smart ! Ideas ??
Looking Good
Hey Doug
Why use vinel ? Spray the foam with bedliner what they use in the back of pick-up trucks.
Is very strong and high quality we also use it for boat venders.
greetings Harm Kramer from Holland
JUST SOME GOOD OL BOYS!!
I sure do like that boat design.
If you use the Acetylene to soot the Aluminum before heating it, the soot burns off at exactly the temp you want to get the Aluminum to (about 700 degf, where Al anneals).
Great boat !! Grinders not welders lmao . Try getting a small bottle of helium and just run 1-2 CFH in with your gas it cleans really well and will look good when not prepped so well. And it will last a while also
The swim platform is on the back and there is lead in it so to lighten the load you might say get the led out of your backside?
Good video
This is amazing
I finally caught up, Joy now I'm on the same page.
That welding process sounds like a bale of turtles banging...lol
Well done well done indeed
Um excelente profissional meus parabéns.
Doug discovers why manhole covers are round at 14:36 lol
crazy cool
Hello Doug. How much sailing or naval experience dose Bart have? Dose Bart have any boat building experience, or are you both just making it up as you go? Please understand, your making it up, is WAY better than average!!! Nothing but the best to you all!
Everyone on the planet is just making it up as they go. Some are just more honest about that. :)
Try using a stainless steel wire brush to clean your welds......something about carbon steel wire brushes leaving an incompatible residue with the aluminum wire.
We have used both. I think that is a good point if your welding something for Space-X but we've never seen any issues.
In welding school we were told to use a stainless brush/wheel (that has never been used on steel) to clean the aluminum before tig welding. My guess that holds true for mig. the reason was not to put any carbon in alloy.
Hi Doug the tender has too much dead rise and will want to roll like a cork at rest. I would urge you to investigate this further before the build progresses to far to rectify. Apart from that an awesome design and concept.
If you turn the Oxygen down on the torch and use it to blacken the Aluminum first with carbon then turn the oxygen up to heat the carbon will flack off just before the aluminum starts to melt.
I've tried that but if you do this enough you get a feel for it. And there is a slight surface change when you get it too hot, so just pull away and wait a few seconds.
ALUM - HEATING >> 'Soot Burnoff' !! . . . as young welder/shipfitter 40 years ago , heating HD alum hatches to free corroded CRS fittings how to know how much heat is enough w/ alum ??? Use Oxy-Fuel torch to put sooty layer on area to be heated then heat JUST until the soot burns off and the alum surface is clean. (Soot burns aprox 900 - 1000degF , Alum melt 1200+degF) , very popular trick since alum does not change color as it heats )
ive noticed on the jet boat build a lot of having to physically push/pull the metal with your whole body, have you thought of using something like a porta power to help free up some hands?
Awesome!
I’m an aluminum welder with experience with Miller and Lincoln machines. Where in Oregon are you maybe I can lend a hand sometime.
Hey Doug. On your main ship, are you using any constrained layer damping panels? It isn't terribly complicated and can make a hell of a difference in attenuation of resonant frequencies.
Awesome
Hello, what would you estimate the cost of all the aluminium for a build like that? / Thanks Kim
The way to shrink metall. Heat upp and cool fast.
*** Aluminum fatigues very easily. As a trucker, I have had my truck cabs components broken from the road vibrations. This is a common problem of aluminum. So I suggest that you BEEF UP THAT JET DRIVE MOUNTING. A heavy built mounting hole to push the boat from needs lots of bracing and overbuilt. Just slapping it in a hole in a sheet of aluminum will not las very long. I cn see that JET DRIVE UNIT ripping itself loose foam the boat...or at least fracturing big cracks that leak badly. Best put in a backing plated and transfer-of-force braces to apply the drive force evenly to a much large area of the boat.
Amazing video, will you cut the foam or pump it in for the back?
when cutting, grinding, sanding aluminum use candle wax on the tool, it will cut like butter and give you a machine like finish. I get my candles at the dollar store. GIT'R DUNNN!!!
you fecking legend!
What about aluminium brazing to fill that gap? It should flow right in. Or even epoxy.
You need drains in that swim platform compartment. No matter how perfect you weld it, water will get in and you need a way to let it out.
It's not intended to stay dry. It will just cover a piece of EPS foam.
Agreed, and an access port to be able to replace the foam IF/When needed. Even the closed cell two part pour foams can get waterlogged with time.
Did you guy's have any thought of annealing the aluminum before assembling the panels???
Safety squinting nearly the whole time looking at my screen. 👍🏽
Outfuckingstanding
Hey Doug instead of working on your boat one weekend when you have a bunch of people, how about working on Bart's tiny house?
maybe bart dont want help, im like that because i have an idea, then some confuser comes along and changes my ideas to theirs and i am like wtf just happened now its their idea and not what i wanted.
Spot on. It takes time to learn when to let go and when to say no.
That's Bart's call.
Anyone know what the boats are in the "what did you build today" slideshow? There are 3 or so pics towards the beginning of the stack.
To cool!
