It went pretty fast with a tiny 500watt drill engine✌🏻 just imagine what it will do with a 170HP superbike engine🤙🏻🤪

[@ollesj5733]

Amazing work you are incredibly talented

[@rjung_ch]

Loving this build, you're doing a great job!

[@Frederikfradk]

I’m impressed👍🏻

[@jasondeel3787]

Awesome build iv been watching for about a year or so now from the lathe pipe binder crosskart the bike boat and the john deer tractor you really do good work engineering and building can't wait to see what's next awesome job.

[@alvaro_builds]

Hell yeah! 🤘🏼

Tip for welding aluminum. Always clean surfaces with acetone before welding, even if it looks clean. Wipe your feed rods with acetone as well. It's a good idea to also use a wire brush or green scotchbrite pad where you plan to weld just to make sure surface residue is gone. For areas that will be welded don't mix materials with abrasives, meaning abrasives used on aluminum should only be used with aluminum. Taper the amps at the end of the weld to prevent suck-back (can be source of cracks). Turn up your post flow time to at least 5 seconds, I usually use 7 seconds minimum at 17-25 cfh. I like using the foot pedal with aluminum because there's a small temp difference between a good consistent weld and having it blow out. Every time you dip the rod it sucks heat out of the weld and can cause it to re-solidify so I usually manually pulse to keep it in the sweet spot. But overall starting out on the thicker material is definitely easier and will help get the basics down with minimal issues.

[@NeoIsrafil]

So true, good tips taco

[@boof_itall3898]

aluminum welder here. good tips, but I never do these things. too many parts, too little time.. if a weld comes out looking like crap, go back over it and manually pulse the foot pedal. perfect every time!

[@BuyBuildThrash]

good tip. didn't know about post flow. I have it at 3 seconds

[@leandrosoaresdacosta1006]

That's right! Nobody told you it was difficult, or even impossible, so you went out there and made it work! What you do is a source of intense inspiration! I'm heading to my garage right now to make that space useful! 🇧🇷 😊

[@WrenchAtHome]

I can't get over the fact that this thing already moved faster under drill-power than my small boat with 4hp outboard Tomos used to go flatout. Amazing work! Looking forward to the next part!

[@dukie1616]

Always so impressed with your skill set. For that being your first aluminum welding project, you sure picked a challenging one. That said, you are doing great as you always do! Always use lots of sealant on all mated surfaces and on any screws sunk, a dab in the hole before you screw it in. Of course you know this so I apologize for my two cents of advice🤗 What a cool project👏

[@JuPac420]

What an amazing engineering feat you accomplished here. So awesome glad I found this channel 👍🏾

[@Henrik.Yngvesson]

When grinding aluminium with abrasive tools a little bit of candle wax helps a lot to prevent it from clogging up and start smearing the aluminium instead of cutting it. Just dab it onto the tool once in a while. When hack sawing the blades might tend to stick and jump so a little cutting fluid, ethanol or WD40 helps and same goes for rotary filing and any blade cutting.

[@SkypowerwithKarl]

Just be really sure you get all the wax off that’s burnished, entrapped or impregnated into the aluminum before you try to weld it.

[@BrianBHatteras43c]

First, excellent video and you have “mad” skills and experience! Second, major kudos to you for doing all the work and making this available to people who want to try their hand and duplicate! New to your channel recently and enjoying every video, keep up the awesome content!

[@aguiloco23]

You have my respect just for the improvised metal bender. Great work!

[@marcus5435]

First just wanted to say, this is absolutely incredible! Secondly, i work a lot with water jets and I definitely recommend you adding a gasket to the connection point between the impeller and the drive nozzle, as any leaks here when you start adding series power will be a massive pain.

[@kene6838]

Just ran across your channel and love the build and I’m not trying to be one of those people but the force of water going thru that pump I’m afraid will blow those wood screw out pretty quickly, I would also glass the plywood box in a little more on the inside and secure the alum. plate on the bottom. Don’t underestimate the power of water. Again I like the build

[@donovancook8218]

Bro is what I was exactly thinking

[@BrokeWrench]

Most of it will see negative pressure. The only part seeing positive pressure is from the impeller to the nozzle and bucket and those are all aluminum and welded.

[@XTJ7]

That would've already been impressive when using the proper tools. But building half the tools necessary for this and achieving such a nice finish? Next level, you are truly incredible.

[@lehighluke]

This is my new favorite channel. I binged everything a couple months ago...now I drop everything when you have a new upload. Your ingenuity is inspirational. Also, I am a professional engineer and CAD expert. I for one can attest to the effort you put into your drawing plans. That must have taken forever. For such a young guy...you have some great skills.

[@hardmanners]

Incredible job! I can already see you building a full blown offshore speedboat

[@bakerfx4968]

(Sharing my expertise since you share yours) The camera settings on the Timelapse isn’t really the source of the problem what I think you’re seeing is banding from the LED lights. You can fix it by using a slower shutter speed or matching it to the hz of the lights. Filming weddings I have to deal with that all the time and it’s annoying lol Slowing the shutter speed on a Timelapse will actually give beneficial results too as you can start to introduce some natural motion blur. Love the content dude! Keep up the good work

[@bchant19]

superb job on tackling this project, As you have found out welding aluminium requires very meticulous cleaning I use a spray solvent from Loctite SF 7070. It works very well dry's fast and cleans off any grease and contamination perfectly. I even use it to wipe the rods down as well its surprising how dirty they are from the drawing processes.

[@ericmeca1108]

A lot of passion and application in this work. Congratulations.

[@henrytaylor3049]

I work in a fab shop, ten years now. I will fight anyone that says your not a master fabricator.👍 BTW welding aluminum is a pain in the ass. Ever if you've done it for years and year's. One of my welders tells me, for him it welds better when the tungsten is more rounded, rather than sharp.🤙

[@jasonhinson3812]

The welding certainly improved throughout this process. Those last weld almost looked professional. Welding aluminum is a bit tricky and I suck at it

[@jimboTTT]

Living the dream! Thanks for filming and sharing it.

[@brodiewilkinson9738]

You’re awesome! Amazing what can be done with hand tools and modern software combined with the dedication and hard work. Great filming and editing too! If you muted the audio during Timelapse’s using power tools and added some rights free music it would be even better.

This is great project no CNC machines all done by hand and it’s looking great and a great motivator I’m wanting to build a little boat now been wanting to do it for years. Your savings on making those parts was a super awesome process that my ass can do at my home shop without a lot of bud dollar tools 🤙

[@NeoIsrafil]

Really cool build man! I need to start doing videos like this. Got a ton of equipment but became disabled, might be able to slowly build cool stuff though when the body allows.. anyway I'm glad the younger generation is getting into the makersphere... so many people don't know how to build ANYTHING, cant even assemble an IKEA furniture, seems like actual crafting is becoming a dying art. Keep the art alive man, youre doing great! By the way, amazon has 2 burner forges for under 200 bucks... if youre interested in expanding your shop and skills. I got one to replace my old diy forge, theyre really nice kits.

One of the first things that you learn in geometry is that a circle is comprised by an infinite number of straight lines 🤔. Great work with the homemade bender. I'm not sure how much cleaning you are doing before aluminium welding, but clean joints with scotchbrite and wipe with acetone first.

Brosif, I have to say this is amazing work. You truly have a gift. In my 35 years of life, I have never seen a metal bender make round shapes.. Maybe I've been living under a rock, but you sir have opened up a new option for me to try! How do you like the welding table so far. I read that it's cast iron.. Does that make any difference to iron sheet when welding, or strength? TIA!

Cool job!! Just have to sub!! Always wanted to make a boat with a jet drive, just a tip when welding Ali clean it with a wire brush or flap disc just before you weld it as you need to remove the oxcide lair before welding and make sure it's really clean , the oxcide has a higher melting point than the Ali.

[@brighambaker3381]

[@Henrik.Yngvesson]

Aluminium forms an oxide layer almost instantly that interferes with welding so you should grind or wire brush it of around the welding areas right before welding. You may want to wipe it of with alcohol as well as the plastic film might have left some residue on the surface.

[@SilvaDreams]

Most would say acetone since it will remove any oils better than alcohol... And some welders would say it's pointless but they are likely ones doing shitty welds.

[@greggo7978]

In my opinion it looks like you did a pretty darn good job for attempting that for the first time. I did however thought that instead of using the aluminum spacer you welded to make the pivots for the turning device which you also threaded in order to use a bolt for fastening the part that pivoted to provide the ability to turn would worry me because of the bolt backing out and resulting in loosing the ability to steer the craft.This brings me to suggest from experience when relying on the mechanical reliability of such design to use a sturdy dowel pin in replace of a bolt.The dowel pin can be welded to the turning device giving you a more reliable pivot.To implement a sleeve on the dowel pin for added wear longevity would be even better,that choice is up to the builder.You will need to install one dowel pin with the pivoting turning device attached, then insert the second dowel threw the pivoting turning device and weld that dowel.Unless a dowel is torn off or another part has a catastrophic failure,you should never loose the ability to turn while the flow of water is being properly supplied .I know I'm not the best at describing things but hopefully it makes some sense. Never the less,well done my friend,you will be building better than most they call experts sooner than you think.
