Plastic welding, custom RV tanks, part 1 of 2 

Wow! Thank you, so much! I'm in the same boat as you were where you couldn't find anything but people doing small projects with Jack leg solutions. This is exactly the information I was looking for to build a couple custom tanks to fit between the floor joists of my cargo trailer! Thank you, so much!

Several of these skills will come in handy for kayak repair!

Great job @Lacroix Cruiser! Erin and I were laughing because we just installed two 30-Gallon HDPE barrels to upcycle them as our gray water tanks. What's funny is that we'll have to cut them in half if we ever want to remove them from the underbody storage. Then @Trevor Robinson passed us this video showing how to fab our own to fit the space in the future. Thanks for the walkthrough! We'll check out Part 2 also! Happy New Year to y'all! - Brian + Erin

very Informative vedio. I have been considering Making a pontoon boat based on structurally welding hdpe barrels end to end. This would allow the flotation element to provide structural rigidity. The process looks very doable without excessive tooling. Retired in Thailand there are limited materials and systems to work with. Thanks for the motivation.

Wow this video just triggered soooo many great ideas in my head, as I am in the process of renovating an Alcan 290 houseboat

Thanks first time I have seen someone actually use hot air plastic welder

Дружище огромное СПАСИБО, за информацию. Здоровенный лайк и подписка👍👍👍👍👍

Great Job, Ivan. I was planning on making mine with marine grade plywood and a fibreglass lining but this looks like a new skill I need to learn. You and Sylvie are upping my game!

That is really cool. Thanks for the how-to that I didn't know I needed!

Love this. I’ve been welding and fabricating plastics for over 24 years. For wet process systems. Love it.

Thanks guys. Thanks a lot. 👍🏾

Lifesaver!! I bought a tank for my carpet cleaning van. I measured height and width thinking nothing of it. The darn thing is too long! I bought a plastic welder about 7 years ago for a project. I thought about welding it but was worried about the pressure from all the water. I'll give it a try! Thanks!!

Very nice Ivan its looks easier than I thought but you make everything look easy thanks for sharing. You learn something everyday with Ivan.

Beautiful knipex

Such a useful tool!

Very nice!

Really enjoyed your video. I do all kinds of specialty fabrication in the medical device industry, and watching you work was informative and entertaining.

Very very nice.good working ppline..thank you..

Thanks, this video was very helpful

Like you know, i worked with your son in the plastic industry. When we need to prep the plastic surface, we first use a plumers propane torch and then go ever it with acetone. I nerver used one of these tool but i'd like to give it a try. It's hard to beleive that a 1/4" sheet of plastic can resist the pressure of 1400 pounds of water. Good job.

Great job sir! You now have a high quality product that you can count on because you did it yourself.

Impressionnnant !! Great workmanship :-0)

Thanks!

Thanks

B&W captures the moment.

Cool le vidéo, cela m'a donné des truc que je vais essayé cette semaine :)

Interesting video, i wonder how they stop with the auto feeding kind. This is new to me. I might have to look into this some more

Currently a trainee plastic fabricator, I'm struggling my self with the flow of using the gun and just started getting used to the different temperatures for different plastics! Hopefully I'll get there thanks for the extra tips in this video as all hot air welders do it differently.

thanks for sharing how you did this

Nice work. Those of you that want healthy lungs Wear Safety Gear + VOC Mask! Plastic fumes are bad news.

Adding to my DIY library!!! What blade are you using to cut I've always had melting issues on a band saw and table saw which made it impossible to get a clean cuts. Always had to shave clean. Great material wished Id known this long ago!! That's a great welder too! Thanks

It appears that the recommendation for baffles is one every 24-30", so 3 on an 80" tank. The extra baffles will also add to the rigidity of the tank. I would also have a few 1-2" holes spread around each baffle.

I am amazed! thank you can I weld a butt joint making two 4'x8'x.125" sheets into a 16 ft long sheet?

6:19 actually prepared for welding.

Thanks, this is a great video! I have a question i hope you or someone can help me with. I have an hdpe (pelican type) container. I want to cut a section out and then platic weld it together. Is that possible using this same method?

great video im trying this and not having great luck...im getting smoke/ fumes coming off when heating...how can you tell if you are at the right temp? Did you have the HDPE emitting fumes/smoke?

This was the best video i found so far to my needs ! Question: is this the same set up i need for trying to weld 2 piece of blue , white , or black plastic 55 gallon drum layer together so i can go buy this plastic welder setup ? Im trying to fabricate my own kayak ? Greatly appreciate your input back !

I live in Belgium. On Amazon I can't order the welding gun. I can order it on ebay but there the feeder for the filament is not included. Where can I order the feeder? Nice job an beautifull explaned , thanks

Hi, i was wondering why you did not "dowel press" or "round knob press" your inner corner welds to seat all three weld beads.....they say it prevents corner leaks?

Do you know what brands make those "professional" welding machine? Im looking for one that self feeds.

Nice tutorial. What material thickness did you use? Can PP replace HDPE for this purpose?

Hey Yvan, When I click on your link for the HDPE rod, the Amazon rod appears to be flat, but you state that yours is round. I cannot seem to find any round rod, except for what appears to be small short ones, maybe 12" or so. Is this the correct link? Thanks.

Are there any welding sticks that melt white? Or do they all melt clear? Do you ever use the triangular sticks?

Im working with plastic 55 gallon blue hdpe drum . Where do i get the temperature specs for that drum to get the right temperature rod ?

Hi there - I’m just wondering now after two years your tanks have held up? Seriously considering building my own tanks like yours

The welding tips in your link doesn't look like it has the same tacking tip your using. Should I look for a tacking tip like you are using?

How many galon is the tank am from the netherlands and we have liters. Looks so beuatiful how You make that to your fan

Great Video. Thank you!! Please advise what brand welding gun do you recommend? One with the hose! Approximately how much should one pay for a decent model? Many thanks

very good work. Could you tell me where to buy the plastic sheets and what type of plastic it is. greetings O

Interesting, thanks for putting up the video. I have a question - how do you know what diameter HDPE rod to use for a given thickness of HDPE sheets? Is this just trial and error or are there actual standards or norms to follow, such as, use 1/8 in. rod to join 1/8 in. thick HDPE? I got curious about this and wasn't able to find any guidelines, e.g., a table or something. Thanks.

Can you tell me what welder you are using and the tip kit

On your center baffle, it looks like you do not have a hole at both lower corners? Having holes in both locations would ensure that water can get from one side to the other regardless of being off-level to either side.

Who is a good supplier for 1.5" and 1/2" female NPT fittings typically used in RV fresh water tanks

This is great! Where are you loacted?

How are the tanks holding up?

Where did you get the plastic deburring tool?

Where do I order the welder with the feeder?

I saw you said $300 for cost, my question is cost versus purchase is there a large enough price difference to make it worthwhile doing? It does seem labour intensive.

What, arent you the guy from DIY Detail ?

Hi can you tell me the make and model numbers of the gun u are using please.

I'm working to build an HDPE skiff (12' boat). I purchased the sheets but am now wondering how to weld and reinforce where the sheets join, such as the bottom to the sides. You say you use metal framing. Boats usually use ribs. And I was thinking of melt-embedding stainless steel mesh in the critical joints. Any ideas on the strength of welds question?

Where did you buy this sheet of plastic

What is the thickness of the HDPE sheeting?

Where would one buy sheets like that?

@0:27 "we've put a plastic cutting blade on the tablesaw" also known as "a blade".

Where can i buy this type of plastic welder? Thanks

Do you think 1/4' HDPE would work?

HDPE is pretty expensive... how much did the materials cost to build this tank?

Plastic tank good for Diesel storage

What brand is the welder?

How to find professionals that can make me one?

No práctico, pero efectivo.

The link for the extra tips doesn’t work anymore 😭 I need a tack tip

Why not just heat bend the plastic ? Bends are leak proof, welds are not

Rod name

I'm supplying plastic wilding rods

Mistake I make when using this tool is far too much pressure or somtimes its skips and bounces but that could be down to being a left hander 🤣

i checked this gun out but i didnt see good reviews.....

I live 5 minutes from U.S. PLASTICS.

I still dont get it. I hope those arent fuel tanks, cuz those joints are weak.

I feel the backache from here...

je suis soudeur plastique air chaud

I have no problems with my wifi speed. Its instant.

I know this work,,Job available for me.

Aapke pass hi kam ho to boliye bhai ji main building maarta hun

Are you seriously using a plastic welder that costs less than $100.00 to do this project?????

Disappointing that this video is in 2 parts without being told in the title...

Loads of Errors 🙄
