Dear bros; Can you experiment with making perfectly straight stripes? I've been trying for a while and it keeps ending up wonky. It'd be really cool if you figured out how to make precise patterns too like checkers or dots. Also, have you guys considered making jewellery/ornaments/keychains? I'm a jeweler and jewellery maker and after watching your videos I've been trying to make jewellery out of my homemade HDPE sheets. Hand sawing it with a jewelers saw Is just too tedious and time consuming so I did research into more effective methods that could cut down on time. I came up with using leather cutting steel dies (but only on thin sheets). It cuts down on sanding down the edges after sawing or cutting and is much cleaner. However it's not perfect because I don't have a die cutting press and the edges still need a little sanding before wear. I've hand sanded but it still is very time consuming to get the desired result compared to metal especially since I can't use my flex shaft because it can accidentally cause damage too quickly. I'm now considering sanding each piece to as close to a final result as I can and then I might experiment placing the pieces in my rock tumbler (in the extra fine grit barrel) with the final grits and polishes and hope that does the trick. I still have not managed to sand them enough (including wet sanding) to get them as shiny as I'd like. However... I was wondering if you guys would be willing to test this out for me as quite a few of my pieces have fine detail and I've spent hours hand sanding them and I'm afraid I'll ruin them... Also, I've been making a list of all product bottles and objects I've discovered that are HDPE. I'm just not sure where that list went at the moment... I will say that the majority of my plastic has come from shampoo and conditioner bottles and laundry detergent and softener bottles. Oh! And I've accidentally discovered that if you leave some sharpie on the plastic and bake it...the colour will bleed into the plastic! (Especially more translucent white plastic... for example: a drywall mudding bucket) I've been experimenting with creating patterns and ombres. I've discovered these colours work: . Standard black sharpie . Dark royal blue (though it won't fully bleed through) . Dark purple (bleeds as fuchsia) . Fuchsia . Red (becomes a pinkish red) . Yellowy green I haven't found much purple or pink plastic so I've been making my own! Note: after baking in the colours you must remove the sharpie film or the plastic won't weld.
@@amandasnider2644 1) Congratulations on your jewelry success so far! 2) Patterns would be awesome! 3) Regarding your list, if I gave you a name brand for a milk bottle cap, then would you be able to confirm with proper research that that specific brand cap is HDPE? 4) How do you know that the ink is safe at that temperature? 5) Speaking of ink, maybe coloured ink could be used to create those patterns that you want. Draw even lines, and then heat? Please, oh please, let me know the results, if you try this.
@@amandasnider2644 regarding fuchsia, I think that our milk bottle caps are that colour. [edit: why don't you test out your sanding and polishing technique using scrap HDPE?]
@@eugenetswong well that explains one reason why I don't have many colour options... I don't drink dairy. Lol As for "ink" I don't know what sharpies have but I don't think regular ink would work because it's more water based and likely would only pool on top of the plastic. As for determining what kind of plastic is appropriate, I don't take chances unless it's clearly labeled.
i started collecting hp plastic from my school and house and started in small projects with the tolls i had thanks to you guys. 💜💜💜 (my english is bad sorry😭💔)
your name seems like you are from an Arab country, is that true? where are you based? which country? my name is Mariam, I would love to know if in case we are from the same country, I would definitely support your small projects !
Watching you guys together, I miss my brother tremendously (he died seven moths ago). Love your brothers while you have each other. A good sibling is a great blessing.
When I was a kid several decades ago, I had a toy set called a spin welder. It had little black plastic girders that I could weld together using a little battery powered gun that basically had a motor that spun a tip that you used to create friction. When applied to the girders, you could melt the material between two adjacent girders and they would fuse together and cool down into an incredibly strong joint. It wasn’t the cleanest looking weld but it sure worked. I wonder if you could do something similar with HDPE? Following my childhood roots, I’ve learned how to weld metal as an adult. I wonder if an intense heat source could be applied to two pieces of HDPE that are next to each other to create a puddle of molten plastic while a thin stick HDPE could be melted into the same joint that is being formed from the puddle. This is how TIG welding works with metal. I’d wager that it would work with plastic. The heat source would simply have to be something other than the electric arc used by a metal arc welder. Some kind of really focused heat gun maybe? There is a company here in the U.S. called Harbor Freight that makes a plastic welding system similar to what I described that might work as an off the shelf system. Just search “Plastic Welder” on their web site. Food for thought. Here’s a link: www.harborfreight.com/search?q=plastic%20welder I think what you guys are doing is fantastic!
Glad to see a process of 'gluing back together'. So far I have made a garden spade handle and a lever knob on a machine with internal metal M11 threads. Getting in a lot of practice turning my metal mold blanks on a 9 inch hobby metal lathe.
Path breakers , Greatest best recycling channel , loads of ideas , very interesting content , people really want to watch , please invent how to blow mould in home with waste plastic especially very big storage jars and how to make it airtight so everything inside will stay fine , thankyou
Instead of melting the actual pieces which would change their size by sometimes quite a bit, score the pieces you're going to 'weld' together - this is ALWAYS done in pottery. Then keep a small can or glass bowl of the same type of plastic heated on a hot plate for instance to the 'just' melting point or a little hotter and use a toothpick or some type of applicator to spread it quickly like 'slip' or glue and then press it.
Made my first small box to enclose an electronics project using your welding techniques! It takes practice but I can see this being a great approach and alternative to the 3D printing I'm always doing.
Watching you lads cleaning up the edges and such is SOOOOOO satisfying. I'd've lost a finger, I 'magine, but it's been ages since I was in a shop. Thank you for making this amazing content.
Just for fun, I taught myself to plastic weld with sunlight and a magnifying glass. It's pretty fun to mess with if you have the patience. It can go pretty quickly on a clear day. Make sure to wear eye protection, sunglasse or light gas welding lenses in goggles. I made welding rod by heating up a piece of scrap and stretched it into about 1/16" - 1/8" rods.
worked in a dodge factory for a short time back in the early 2000's and plastic welding was rather common there. those tanks to hold the windshield washer fluid for example are 2 haves that get pressed up against a plate of steel that is kept super hot then lowered down and pressed together by a machine just required one of us hooomans to put the parts in and hit the go button.
@@BrothersMake wish i had a workshop and tools to try and make stuff currently all i can do is melt the stuff into sort of blanks to take up less space. got quite a bit i use those disposable foil baking trays and just recycle them after plastic cools and toss the rough blanks into a bucket. perhaps someday when i get a house again apartment city life is no fun lol.
Parabéns!! É lindo o trabalho de vocês! Aqui no Brasil precisamos de pessoas como vocês, material é que não iria faltar! Parabéns !! Reciclagem boa é aquela que não parece reciclagem e vocês deram um show! Ganharam mais uma seguidora!
HDPE has been welded for quite a while now. Specific setups for HDPE and the welding you plan to do. Eg; Long thick runs, short runs, angled runs, etc...extruders, soldier type tips, etc... On and on. Keep it up guys! Love the content! Soooo many applications for HDPE. Plus, it sits in the landfills for centuries so recycling key! The biggest problem, for me anyways, of tackling a new skill is the unknown. You guys are showing just how easy it is! Shared and liked!
Buy a plastic weld gun or a extruder weld nossel for your heat gun, you can make your own extruder weld rodds with the same color as your plates. The technique you use with the contact grill can be described as mirror welding, widely used for welding hd-pe and pp pipes lengths together .
Speaking about plastic weld gun/extruder I was wondering about the high cost of an industrial extruder plastic welder, wich is made of a drill and a hot air gun combined...
Sorry to have to say it but I am glad your other project was put on hold. :P I love all your HDPE videos and it is why I initially subscribed. ;) I also love making boxes so this one really ticked all my boxes... *grin* Thanks for sharing the video and that box is super lovely!! Love the color mix. - Heidi
We did think this, but was concerned it would take too long to connect it all together after the plastic turns soft. May be tricky to do in the narrow window of heat. But worth a try!
Some of those shopping bags are the same material as the plastic milk bottles. Some but by no means all. Those which are are the exact same thing, that being HDPE. I picked up such a bag off the street the other day and I used it to carry my cigars home in. It says HDPE on it, and if it says HDPE then it could go in with the HDPE milk bottles. It necessarily could. Such a bag needs to be of a particular constituency from among all plastic shopping bags.
Think Energy Efficiency: Heat only the surfaces to be joined in 1 of 2 ways: 1. Position both parts together and run a high speed friction disk between them to heat and join. 2. Position both parts together under pressure and run an electric hot knife between them to fuse them before any cooling can occur. And thanks for sharing!
love your work and your personalities. Keep up the great job you are doing and presenting to the public. I have my husband interested in the pens because he collects pens. M from Canada. Since we are also in lock down this is a good time to play around with different ideas and we love to recycle.
Not sure if somebody mentioned this, but I did an experiment before and used a box knife to barely scribe my piece to be 'cut' and tried to break my piece that I needed on the edge of my work bench rather than saw cut. It worked quite well! Later I was machining a block of HDPE with a square end mill and four separate 'tangs' were left. Since I had an extra I decided to push on the tab because of the sharp corner (thinking of my light box knife scribe in the past) and sure enough it snapped rather easily. So, what makes the the pieces stay together a lot better is leaving a smooth radius in the corner. I'm guessing this would help when doing this process in the video too rather than cleaning up the inside corners with a razor making them sharp.
One of the methods for "gluing" plastic together is to use solvent and a sonic welder. This I know as I worked in plastics for about 7 years and one of the things we made were plastic casings for an industrial vacuum system for Hoover. Solvent would be applied around the edges of the main case and then the cover clamped in place and then placed under a sonic welder briefly.
I feel like ever since you guys sealed the thicknesser or whatever its called with tape for the waste to be directed into the bottle more of it is coming out of other corners. it probably helps to make some holes in the bottle or something so it can perform as a vacuum also the things you guys are making are literally pieces of art! like they're so pretty I'd literally frame and hang them on the wall as modern art
Yeah that’s probably not a bad idea. The dust port is never 100% effective on these machines. We make sure to pick up all the small pieces that don’t go into the bottle. Thank you so much!
As a woodworker, my suggestion would be to use a half-lap joint for more bonding surface area. That likely wouldn't work well in the panini press, but would work pretty well with a heat gun I should think. Would be pretty difficult to melt a dado joint with the way the plastic deforms when hot, yes?
idk if someone else has mentioned it already but there's this thing in the 3d printing community called friction welding. Which is where you take a dremel and use a piece of excess filament as a bit. Since this piece of filament is spinning at such a high speed it and the piece it is touching (if made of the same material) melt on contact. This method works specifically well with PLA plastic, I printed a helmet for a costume and welded the pieces together by doing this. I wonder if you could do the same with HDPE due to its low melting point, especially if you were to extrude wires of HDPE at a similar width to 3d printer filament. For heavier duty plastic like ABS I like to take a soldering iron and make a jagged pattern across the seam line (think like the look of saw teeth) and that seems to hold together really well.
You’re not wrong with the concept, it will work, but won’t be strong. The correct way to weld HDPE is to heat to its fusion temp with the correct amount of pressure at each interval, then as fast as possible push together and hold for a certain amount of time before letting go and allowing full cool down. Quite different to other techniques for plastic welding. Source - I’m trained and licensed on ISO21307 hdpe butt fusion.
You may want to try cutting out notches on each side of the plastic you are going to weld. You could also try to inbed peices of wood or plastic dow rods into the corners for a stronger joint. I would love to see you give it a shot. Thanks for the vids.
I had a hundred plus gallon plastic water tank with a dinner plate sized HOLE in it that I wanted fixed. I got an extra sheet of the plastic and cut out the round to fill the hole, then used my wood burning tool to melt strips of plastic in and around all the edges I wanted joined. It came out GREAT. So yes, plastic CAN be welded this way, and even if you don't have a special tool, just heat up a screwdriver tip in a fire!
i think the best method in this case of a box is to make a dove joint like you would in wood working (hehe), and then with a heatgun melt the joint tight, that way you have mechanical and chemical power.
Idea for joining technique: temporarily glue with CA glue (maybe roughing up the parts to help?) then drill holes for "dowel" joinery: get a metal rod hot to melt the hole from the inside, heat a plastic dowel up, then squish it in good and propper. i think a few well melted dowels could provide greater strength than the larger semi melted joint. plus it seems like it'd be less fiddly to do complex joinery. edit: on further consideration: scrap the plastic dowel and just screw the pieces together with hot wood screws after piloting and countersinking. then while the screw is still hot and the hole melty finish it off with more melted plastic to fill the countersink. that's gotta be better.
Don't expect you guys to notice a comment this late on. you're probably all over it now but 45's in the corners might be ever so slightly stronger as there's more contact area? Just made my first block of hdpe today from motivation I got from you guys. Turned out terribly, but really keen on keeping on. Thanks lads
You could try using a soldering iron, they also come with different tips you could use, it comes in handy using zip ties to fix or join other plastics together
What would happen if you interlocked them first with something like a dove tail and then melthen the corners using the heat gun or press? Does the heat not penetrate enough to melt the joint?
Great videos... Thank you! There are a couple of HPDE experiments I'd enjoy seeing if you have the time: 1) Rather than trimming the inside corners with a straight chisel, try a radiused blade (X-ACTO #13813 or #13869, for example). I'm wondering whether the straight chisel is leaving one or more stress risers, which might result in a weaker joint than the fillet left by a radiused tool. 2) From each block of raw material you make, cut small rods (~ 3mm square) and then use them as welding rod in conjunction with the heat gun. Thanks again!
Have you tried spin welding? You put a piece of plastic rod in a Dremel and the heat of friction melts the workpiece and rod together. It’s a strong joint as the spinning also mixes the melted plastic rod and workpiece.
I would say that this is heat bonding ( if that's the correct expression). Have you tried the heat welding tools the the "vinyl " floor layers use to weld seams. This may give you more flexibility. Good watching - thank you
I actually found this video trying to see if anyone has done this for boxes on kayak trailers. But an idea more people might be interested in seeing done is a truck tool box.
As the HDPE works like timber in theory you could use Japanese carpentry techniques to make joins, this would cut down the need for screws as well. Anyway great video.
Wow, that worked really well. In fixing 3D prints, I've tried using friction stir welding with a little bit of success. (but that's PLA) I wonder if that might be something to try for applications when you need weld a smaller area.
Have you thought about making storage things for the hobby crafter ? I need holders for my double sided tape and Nuvo drops and Tombo glue bottles to name a few. Love that box x
I do a lot of kayak repairs. Different brands have different priorities. I'll heat the surface and touch it with different Plastics till one of them bonds. I'll fill the gap/hole with that plastic. Cool it & test for leaks Then I'll melt aluminum mesh (window screen cut in oval shapes) with the flat end of a wood burning tool into the plastic covering the patched area. Then I'll heat the surface and coat it again with more plastic. The edges don't always look too great but the mesh really bonds the 2 surfaces.
By the way. I use a rubber roller on the hot surfs to smooth the finish. If the surface is textured I'll just press a piece of plastic with the same texture onto the hot surface to make it match (kind of)

Dear bros;
Can you experiment with making perfectly straight stripes? I've been trying for a while and it keeps ending up wonky. It'd be really cool if you figured out how to make precise patterns too like checkers or dots.
Also, have you guys considered making jewellery/ornaments/keychains?
I'm a jeweler and jewellery maker and after watching your videos I've been trying to make jewellery out of my homemade HDPE sheets. Hand sawing it with a jewelers saw Is just too tedious and time consuming so I did research into more effective methods that could cut down on time. I came up with using leather cutting steel dies (but only on thin sheets). It cuts down on sanding down the edges after sawing or cutting and is much cleaner. However it's not perfect because I don't have a die cutting press and the edges still need a little sanding before wear. I've hand sanded but it still is very time consuming to get the desired result compared to metal especially since I can't use my flex shaft because it can accidentally cause damage too quickly. I'm now considering sanding each piece to as close to a final result as I can and then I might experiment placing the pieces in my rock tumbler (in the extra fine grit barrel) with the final grits and polishes and hope that does the trick. I still have not managed to sand them enough (including wet sanding) to get them as shiny as I'd like.
However... I was wondering if you guys would be willing to test this out for me as quite a few of my pieces have fine detail and I've spent hours hand sanding them and I'm afraid I'll ruin them...
Also, I've been making a list of all product bottles and objects I've discovered that are HDPE. I'm just not sure where that list went at the moment... I will say that the majority of my plastic has come from shampoo and conditioner bottles and laundry detergent and softener bottles.
Oh! And I've accidentally discovered that if you leave some sharpie on the plastic and bake it...the colour will bleed into the plastic! (Especially more translucent white plastic... for example: a drywall mudding bucket)
I've been experimenting with creating patterns and ombres.
I've discovered these colours work:
. Standard black sharpie
. Dark royal blue (though it won't fully bleed through)
. Dark purple (bleeds as fuchsia)
. Fuchsia
. Red (becomes a pinkish red)
. Yellowy green
I haven't found much purple or pink plastic so I've been making my own!
Note: after baking in the colours you must remove the sharpie film or the plastic won't weld.

You can do a box joint or a dovetail joint before heating so it will be more stiffer.
A very nice box btw.
We did think this, but was concerned it would take too long to connect it all together after the plastic turns soft. May be tricky to do in the narrow window of heat. But worth a try!

Not sure if somebody mentioned this, but I did an experiment before and used a box knife to barely scribe my piece to be 'cut' and tried to break my piece that I needed on the edge of my work bench rather than saw cut. It worked quite well! Later I was machining a block of HDPE with a square end mill and four separate 'tangs' were left. Since I had an extra I decided to push on the tab because of the sharp corner (thinking of my light box knife scribe in the past) and sure enough it snapped rather easily. So, what makes the the pieces stay together a lot better is leaving a smooth radius in the corner. I'm guessing this would help when doing this process in the video too rather than cleaning up the inside corners with a razor making them sharp.
I would definitely buy one off these
Hello my friend.
Good idea. I like this box. good job. congratulations. Thank you for sharing. See you. big greetings.
Thank you!

One of the methods for "gluing" plastic together is to use solvent and a sonic welder. This I know as I worked in plastics for about 7 years and one of the things we made were plastic casings for an industrial vacuum system for Hoover. Solvent would be applied around the edges of the main case and then the cover clamped in place and then placed under a sonic welder briefly.
Beautiful design and colour 😊💞🎉 thx
OMGosh this is awesome
I feel like ever since you guys sealed the thicknesser or whatever its called with tape for the waste to be directed into the bottle more of it is coming out of other corners. it probably helps to make some holes in the bottle or something so it can perform as a vacuum
also the things you guys are making are literally pieces of art! like they're so pretty I'd literally frame and hang them on the wall as modern art
Yeah that’s probably not a bad idea. The dust port is never 100% effective on these machines. We make sure to pick up all the small pieces that don’t go into the bottle.
Thank you so much!
As a woodworker, my suggestion would be to use a half-lap joint for more bonding surface area. That likely wouldn't work well in the panini press, but would work pretty well with a heat gun I should think. Would be pretty difficult to melt a dado joint with the way the plastic deforms when hot, yes?
That was awesome!!!
You two are so creative! You are amazing! 💜💜💜
Thank you!
I loved every video
Thank you so much!
You guys at brilliant!! Love watching these videos. So creative!!!
Thanks Wendy!
idk if someone else has mentioned it already but there's this thing in the 3d printing community called friction welding. Which is where you take a dremel and use a piece of excess filament as a bit. Since this piece of filament is spinning at such a high speed it and the piece it is touching (if made of the same material) melt on contact. This method works specifically well with PLA plastic, I printed a helmet for a costume and welded the pieces together by doing this. I wonder if you could do the same with HDPE due to its low melting point, especially if you were to extrude wires of HDPE at a similar width to 3d printer filament. For heavier duty plastic like ABS I like to take a soldering iron and make a jagged pattern across the seam line (think like the look of saw teeth) and that seems to hold together really well.
You’re not wrong with the concept, it will work, but won’t be strong. The correct way to weld HDPE is to heat to its fusion temp with the correct amount of pressure at each interval, then as fast as possible push together and hold for a certain amount of time before letting go and allowing full cool down. Quite different to other techniques for plastic welding. Source - I’m trained and licensed on ISO21307 hdpe butt fusion.
Magnifique 🤩 bravo 👏🏽👏🏽👏🏽
I would love to see some sort of welded polyhedron, like a Buckyball! Maybe with cutouts in the faces so you could see all the way through it...
Such an inspiration!
You may want to try cutting out notches on each side of the plastic you are going to weld. You could also try to inbed peices of wood or plastic dow rods into the corners for a stronger joint. I would love to see you give it a shot. Thanks for the vids.
I really love the idea. New fan here
Thanks so much for watching!
Hi Guys yet another great project, yet to see the blue HDPE I gave you being used for something cool.
All in good time my friend!
You could do dovetails and melt them together with the heat gun.
That would make an insane looking kitchen countertop.
Nice idea. And it really would! We want to use it to tile our kitchen next 👌🏼
Very cool! Love the end result great colour combination!
Thanks!
You are very good. I am from Russia
Nice video 👍
Ther are glues on the market that can glue hdpe and other plastics.
For example TENSOL 12 BONDING Adhesive.
Drawers would be kewl I wonder if they can support all the stuff involved with it
Yes most likely!
I had a hundred plus gallon plastic water tank with a dinner plate sized HOLE in it that I wanted fixed. I got an extra sheet of the plastic and cut out the round to fill the hole, then used my wood burning tool to melt strips of plastic in and around all the edges I wanted joined. It came out GREAT. So yes, plastic CAN be welded this way, and even if you don't have a special tool, just heat up a screwdriver tip in a fire!
Make some super sturdy plastic Adirondack chairs for really, really heavy short people like me..
i think the best method in this case of a box is to make a dove joint like you would in wood working (hehe), and then with a heatgun melt the joint tight, that way you have mechanical and chemical power.
A recycled infinity mirror would be a great project, i am thinking of trying a 7 foot high x 4 foot wide one using your techniques.
Idea for joining technique: temporarily glue with CA glue (maybe roughing up the parts to help?) then drill holes for "dowel" joinery: get a metal rod hot to melt the hole from the inside, heat a plastic dowel up, then squish it in good and propper. i think a few well melted dowels could provide greater strength than the larger semi melted joint. plus it seems like it'd be less fiddly to do complex joinery.
edit: on further consideration: scrap the plastic dowel and just screw the pieces together with hot wood screws after piloting and countersinking. then while the screw is still hot and the hole melty finish it off with more melted plastic to fill the countersink. that's gotta be better.
Don't expect you guys to notice a comment this late on. you're probably all over it now but 45's in the corners might be ever so slightly stronger as there's more contact area? Just made my first block of hdpe today from motivation I got from you guys. Turned out terribly, but really keen on keeping on. Thanks lads
Thank you 😊
You’re welcome!
You could try using a soldering iron, they also come with different tips you could use, it comes in handy using zip ties to fix or join other plastics together
What would happen if you interlocked them first with something like a dove tail and then melthen the corners using the heat gun or press? Does the heat not penetrate enough to melt the joint?
This is a great suggestion!
The frame for sunglasses would be kinda cool
Very cool!
An adjustable soldering iron work well for plastic welding, put a bevel on you edges and some filler, and weld away
Sounds like it could work well!
Great videos... Thank you!
There are a couple of HPDE experiments I'd enjoy seeing if you have the time:
1) Rather than trimming the inside corners with a straight chisel, try a radiused blade (X-ACTO #13813 or #13869, for example). I'm wondering whether the straight chisel is leaving one or more stress risers, which might result in a weaker joint than the fillet left by a radiused tool.
2) From each block of raw material you make, cut small rods (~ 3mm square) and then use them as welding rod in conjunction with the heat gun.
Thanks again!
Thanks! And good ideas, we'll see what we can do 🤙🏼
You guys are really talented and funny, and passionate about cleaning mother earth. How about rings to go with necklaces? Larry in Asheville, NC
would love to see you guys do a flower pot design! Great video!
flower/plant pot
We’ve got one coming up!
Brothers Make awesome! Glad I subscribed! :)
Have you tried spin welding? You put a piece of plastic rod in a Dremel and the heat of friction melts the workpiece and rod together. It’s a strong joint as the spinning also mixes the melted plastic rod and workpiece.
I use a soldering gun and zip ties to weld plastic .it works great.
I would say that this is heat bonding ( if that's the correct expression). Have you tried the heat welding tools the the "vinyl " floor layers use to weld seams. This may give you more flexibility. Good watching - thank you
I actually found this video trying to see if anyone has done this for boxes on kayak trailers. But an idea more people might be interested in seeing done is a truck tool box.
As the HDPE works like timber in theory you could use Japanese carpentry techniques to make joins, this would cut down the need for screws as well.
Anyway great video.
That's a great idea!
I used my pressing clothes hot iron and parchment paper to flatten the cut out cylinder of a plastic bottle to make sheet or panel.
Love it
Love this and the colours are brilliant. Xxx
Thanks Shirley!
Great Channel btw
Thanks! 😊
Wow, that worked really well.
In fixing 3D prints, I've tried using friction stir welding with a little bit of success. (but that's PLA)
I wonder if that might be something to try for applications when you need weld a smaller area.
That could be very interesting to test!
Have you thought about making storage things for the hobby crafter ? I need holders for my double sided tape and Nuvo drops and Tombo glue bottles to name a few. Love that box x
That’s a good idea!
Found you guys through a facebook ad from DIY & Crafts. They have you video on their page but from what I can see it's been edited very differently
Yes they have permission. Thanks for the heads up!
@@BrothersMake ok, i've seen some where the creator didn't know. So I always like to let them know how I find them
I do a lot of kayak repairs.
Different brands have different priorities.
I'll heat the surface and touch it with different Plastics till one of them bonds.
I'll fill the gap/hole with that plastic.
Cool it & test for leaks
Then I'll melt aluminum mesh (window screen cut in oval shapes) with the flat end of a wood burning tool into the plastic covering the patched area.
Then I'll heat the surface and coat it again with more plastic.
The edges don't always look too great but the mesh really bonds the 2 surfaces.
By the way. I use a rubber roller on the hot surfs to smooth the finish.
If the surface is textured I'll just press a piece of plastic with the same texture onto the hot surface to make it match (kind of)
No one gets a joke better than your sibling.🤗
Haha! Too true!
I've repaired plastics that don't like glue with a soldering iron and some spare material to use as a filler.
