How to Make a Larger Vacuum Former | I Like To Make Stuff

[@drvfstrlt1]

We built a massive version of this about 10 years ago for the SAE Baja team I was on. After a form was made, it made body panels for the car in about 10 minutes a set. Huge time saver.

[@JaredMize9]

Craziest timing. I watched 10 different vacuum former videos with Hayden last night and then this came up this morning! And thank you for the time you spent with her at Maker Faire. She’s still raving about it to her friends. Btw, a scroll saw was the first tool I ever bought her about a year ago. We obviously think alike when it comes to “safe” tools for our kids.

[@Iliketomakestuff]

Awesome! Great to have met you guys. Also, make sure you listen to the new podcast that comes out tomorrow 😉

[@JaredMize9]

[@naivlyssillig6728]

Five years ago i started to follow you with your first vaccum former. Congratulations for your projects and your succes.

[@qbaker20]

Hey, Bob. Glad you are going to be able to vacuum pack your wrenches so they don't go rancid as quickly. I hate having to throw away wrenches that have gone off while most of the metal was still good.

[@Roadsterrick69]

No uptalk…to the point…no uhs or ands…steady camera…good lighting…well done.

[@EcoMouseChannel]

For anyone wanting to make their own vacuum forming machine, here's a pro-tip that will get you great results even as a beginner. You need your vacuum box to be able to fit INSIDE your frame clamp. That way when you pull down your styrene, the plastic wraps tighter around the base of your object bucks. (That means you can't directly fasten the legs to the vacuum box underneath. Unless you make a tiered cake box, where the vacuum forming area is elevated and smaller than the whole box underneath) I've made several of these over the years, and the most convenient items to start with are actually metal baking trays. Use one to contain your heating elements, and use the other as the base in which you pull vacuum through. Yeah, drilling holes in the metal pan is gonna suck a little more... but the results are more worth it and your homemade vacuum former starts to rival "professional" versions.

[@mitchtaylor7725]

Epic tip. Cheers!

[@Pani29k]

Thanks for posting. Would you have pictures of the setup ?

[@thomaswiley666]

I still worry about the urea-formaldehyde offgassing of generic MDF. I know MDF is a cheap to use but heat will only hasten the breakdown. Any alternatives besides metal?

[@raymondfaus6853]

A suggestion- use melamine. As you know, production CNC routers often have vacuum tables and pneumatic dogs. The waste sheet is MDF, with the vacuum pulling through the MDF to secure the cut sheet. That’s because MDF will allow air to pass through, pulling the cut sheet down. It’s permeable. If you use melamine and melamine glue…it’s still inexpensive, but will improve any vacuum carcass you’d build for a vacuum form machine. As a matter of fact, melamine is cheaper than MDF. Trust me…this is years of commercial fixture production experience speaking to you.

[@ThomasTheFapEngine]

Thanks for the tip Ray :D

This was by far the simplest version of making a vacuum former I have seen, and I love the simple design of the boxes and how they are connected. I am sitting and planning my own former so this video was great ^^

[@MoPoppins]

Like COWBELL and CLAMPS...never enough.

[@lucasdouble-u4010]

i have 2 notes : 1) what could help and what usually is done is a pre blow which stretches the material so when it lands on the object you don't have to rely on the vacuum that much . 2) is that when for example you do your camera , you should tape of the holes on your board except those within an inch so that the vacuum is strong where it needs to be. love the vid FYI

[@artiet5982]

I may not make a former like this, but I picked up a lot of other great tips for my everyday woodworking in this video, one reason I like your videos so much. Thanks Bob! Great video

[@CPoddy]

Absolutely perfect video dude! It’s so nice to see someone making such an intelligent step by step instruction video without wasting a single frame. Maybe you should go to go to Hollywood. They could use a guy like you! Seriously!

This Joe, Karna husband. I like your tool rack. It was behind you in this build video. GOD Bless you and your family. Amen

[@admirburzic3303]

Sugestion: Move the plastic a few inches further away from the heater, it will take longer to heat it up but you may get a larger heated surface. :)

[@nativ3_h3tke73]

I’m starting a business, and one element is I need to make my own protective cases. I remember watching the first video on this thing 5 years ago, glad I found it again

[@abbv2x]

As an electrician I cringe when I see DIY's mod electrical devices. While watching this vid, I...cringed, but thankfully you follow it immediately with words of caution and WHY to be cautious. Thank you very much for keeping viewers informed and safe! I really liked this project. For nothing more that a "cool factor", add a limit switch to the upper portion of the form that turns the vacuum on when you release the frame from the magnets :)

[@Docv400]

Nice job, I’ve been wanting to make a Vacuum Former for years. One tip though, wear a Mask when cutting/sanding/planing MDF, the dust is highly carcinogenic.

[@HorrorFXDesigns]

What is MDF? Im looking for a good molding resin to pour in to a silicon mold to make a buck for vacuum forming? Im trying to get a mold for my vacuum former to vacuum form hockey masks, but the bucks ive been using for these don't last at all. I want a really rigid hockey mask buck for vacuum forming many copies from.

[@azmike1956]

John Warner absolutely. MDF is even an instant sinus infection.

[@Lux158]

to seal the box right you have to paint it with epoxy.. MDF is pretty breathable and is even used to suck down pieces onto a cic-router-table. I really enjoy all your videos!

[@breakfixmake3405]

[@juliettedelicia9950]

[@Lejackal]

Totally having tool envy over that CNC, nice build

[@ytsjcuser]

Very cool build. I've been wanting to make one of these but the biggest hurdle was the "cradle" system to lower the frame holder to the vacuum surface. The fact that you skipped any type of complicated raising/lowering system by simply using a separate plastic holder and magnets was a smart move. This reignites my desire to make one of these machines. Good job (as always).

[@Mike__B]

Some changes that just running through my mind, unsure if they're actually useful. First ditch the clips, they will prevent getting a really good seal when you press it down, instead have both top and bottom metal frames have those handles then make your wood covers such that you can slide those right on and hold both top and bottom together, then your gasket at the bottom will be much more effective since there won't be any gaps. Another option if you don't want to do that is put tabs around your frame that extend past the gasket then use those to put the clips on to. Second is your heating element. Instead of having the heating element so close to the plastic, burn issues, make a larger box run the output on the shopvac up to the heating box and create forced air situation so you can more evenly heat everything, and you might be able to use other plastic too. Or if you don't have a virgin shopvac (no dust) throw some computer fans up there to blow the air around. Lastly is there any issue with the fumes that would be putting off when you're melting plastic?

[@timstafford4934]

Its better to make a raised section in the middle smaller than the main beed so the frame wraps around it..

[@nefix4m4n]

Dude you are awesome, I'm using heat resistors which are difficult to attach and keep in place, but your idea to use a heater is just magnificent

[@Volte6]

It probably has a unnoticeable impact, but air actually leaks through solid MDF. Sealing the actual MDF surface (even with just wood glue) might have some efficiency gains.

[@TheNigaHigaFan4Ever]

blah Thats probably right but sealing those gaps between the mdfs would help a lot, and the sealing platform and plastic

[@doubledarefan]

The paint job probably solved that.

[@TheNigaHigaFan4Ever]

Double Dare Fan the gabs between or the mdf?

[@doubledarefan]

Gabs? Did you mean gaps? The glue seemed to take care of that. I meant the MDF itself, which is central to blah's question.

[@Hubbmade]

[@Bmk0017]

I’ve gotten to play with a few of these at Auburn University, specifically one that does full 4x8 sheets of abs. One trick they use to get cleaner pulls is to use a piece of wood or a silicone spatula to even out the creases. We also just used quarters to space the objects of the vacuum table. You could also try drilling small holes through the object to get more surface detail, a 1/16-3/32 but should be fine for thinner plastics

I want to caution you that those handheld masks should be held to your face, there is a significant amount of UV radiation generated by the welder, which bounces off of nearby surfaces and will make it back to your eyes. You should be shielding your face, not the arc, for best protection.

[@originaltrilogy1]

Absolutely correct! You end up with quite a lot of UV exposure otherwise.

[@AdamusPrime76]

Eyeball burns are no bueno. The uv bounces off everything....everything

[@davemarm]

Why did he resort to using that handheld one to begin with? The only issue was that the battery died in his auto-darkening helmet but it should still provide protection without the darkening feature.

[@TheUnamazingRando]

or he could have easily resolved that by going to the store and getting a new battery! cr2032's are not hard to find or expensive by any means... oh well. it gives welders something to cringe at! lol

[@chattermark5799]

Nice work. Two remarks: Neodymium magnets loose their power when heated above 90 deg centigrade - irreversably. A snap-on lock might be better on the long run Industrial vacuum fomers use a two step push- and pull-process. Specially when copying high rising molds, they first blow up a bubble in the sheet, then move in the mould from below, and finally apply the vacuum. That enhances the wall thickness in vertical surfaces. But more than a diy project. Reversing the orientation (sheet on the bottom, mould mounted above it) could be a way to go. Hot air instead of the IR heater could also help get it heated more evenly.

[@acoffeewithsatan]

Cool project as always! You've said in the past you often end up forgetting wearing the dust mask - always do so when cutting MDF. The sawdust of that material is very harmful...

[@kubalarysz7601]

I love your channel it's really crafty and I love this vacuum former

[@Youmnfr]

Hey bob, one piece of advice, i think that the vacuuming box should be more insulated, like with a coat of silicone or something like that and maybe stepping up your actual vacuum with something with more power. Flux is inversely proportional to the area so you need more "sucking power"

[@MaltandMake]

I wonder if you could make the handles the clamps? If you put metal sticking out on both the top and bottom parts of the plastic 'carrier' you could sandwich the plastic between each part and then put on the handles to clamp it in place. You might need different handles if you used different thickness of plastic but I think it's an elegant solution to the clamp problem.

[@Iliketomakestuff]

You could but you also need clamping pressure on all 4 sides. As the plastic gets stretched, it needs to stay put in the frame on all sides.

[@fusionviper7682]

i commented the same thing then i saw yours 😂great minds think alike.

[@byteofblender]

Also hadn't seen this until after I had posted the same thing myself. What if you gave the steel frame parts a slight curvature so that they apply pressure on the two sides without handles, like this poor diagram --> top,plastic,bottom = )|(

[@GrayHatter]

maybe a piano hinge on one side of the "carrier". Then you'd only have to clamp one side

[@julesmikeknaggs5659]

If you added some tags around all sides and clamp those instead, maybe lower the plastic, so the heater can cover a larger area, it might take longer to soften though..

[@u10ajf]

Very cool stuff. If I had one of these I'd make a parabolic dish and record bird song with it. I think it'd be the easiest shape in the world to vacuum form - so simple and regular.

[@Vatsek]

A very nice project.

[@wihamaki]

If you want a good idea how to vacuum-form plastics, find a place that makes orthopedics. We use to cook our plastics sometimes on top of fabric in an oven on a large silicon sprayed aluminum sheet. Once draped over the vacuum box, the cloth would be removed since it prevents the plastic from drooping all over the place handling it from stove to vacuum. To do something like the head you did, I would make a cast of it out of plaster with a vaseline'd vacuum pipe in it. The cast would have fabric or nylons over it to promote a vacuum throughout the part. The plastic would be draped over the cast, pulled around and then stuck together, working your way up to the vacuum pipe. Once you squeeze the plastic (wearing appropriate gloves the entire time) off at the pipe, it will suck completely around the cast. You can also heat up foam and use a plastic bag to seal it to the vacuum box or pipe. Once cooled, staple it to the cast to hold it in place, rough it up with some course grit sandpaper and pull plastic over it and the two layers will stick. We often used 'white' plastic that you knew was up to temperature when it went clear in the over. If you're using plaster for casts, you can shape it with car body files and smooth it with wet screen (like from a screen door). But note if the plaster hasn't had time to dry out, you can pull water and plaster right off the cast. If one was using plaster for laminating instead, some seal it off first.

[@boominghawk]

don't magnets start to lose their magnetic properties when heated up ?

[@hanelyp1]

Magnets lose magnetism at a much higher temperature than the plastic should ever see for thermoforming.

[@EcoMouseChannel]

The Curie Temperature for a typical Neodymium Magnet is about 340°C (644°F) Waaay hotter than even your standard oven.

[@corneliusgriggs8525]

You're right, some of the rare earth magnets start degrading at rather low temps.

[@airwolf269]

Great video nice work. For thermoforming a nice tight part a infrared quartz heater is the best to heat your material. PTEG is realy fun to work with. Anyways back in the day we used Kell rod heaters AKA Cartridge & Rod Heaters. Then you will need a clamp fram to seal your project to not have any vacuum leaks next would be a pressure box to pressurize to help push down the plastic and used together can stop webing finally cooling the part. but used together with perfect timing can control thin walls. then most important air eject to help remove part from mold.

BETTER EVERY TIME!

[@Makebuildmodify]

I've been wondering if a heater like that would work for a vacuum former. It's performing better than I thought for a heater that size. Great project!

[@IconicProps]

The simplest is a 'electric grill heater'. It is 110, comes with a heater controller. You can use 1 or 2 depending on size. They are move than 10 amps, so youll need a 110 on a 20 amp breaker, or you will need to plug it in to another rooms if you use 2. The best way would be to build a pyramid shaped heat box. Going from heater size, to plastic size. That way you get perfect radiation of heat. If you just put it in the center of box, you will get dead spots. Also, the platen, should be smaller than the plastic, so the plastic wraps around the edges of the platen, that will give a much better seal. Your best bet, is to take a look at a store bought vac former, and you will see a lot of the design flaws in home builts.

[@Makebuildmodify]

@@IconicProps That all make a lot of sense. Thanks!

[@MidnightMaker]

bit late to the party but great video. i made one as well and it works really well. i did change one thing and that was replacing the neodymium magnets with ferrite ones. like the ones on a fridge but on steroids. I did that because neo's loss the magnetic field of they heat up above 60C and ferrites can handle around 200C. this was too prevent it from losing its grip on the plastic holder while you are waiting or if you are using it for a while.

To keep the camera from blinking in and out, you have to set the exposure so that it stays constant. That's it.

[@JoshMakesStuff]

Sounds like someone needs to up their internet stalker game.

[@crazyminecrafter14]

For the clamping you can also use some small bolts with holes in the vacuum box on the places that they touch the vacuum box, so you have a flush contact and better vacuum. Also for more equal warming of the plastic place it a bit further as I think it is to close and doesn't heat the edges properly, which may turn out to be a problem when trying to form bigger objects.

[@jdgindustries2734]

Once again Bob, awesome work. Was this filmed at the old house? Looks like the old shop. By the way, thanks for adding yet ANOTHER project to my list of things to make for our hackerspace (The Make Space in State College PA).

[@Iliketomakestuff]

Thanks! No, this one is in the new shop. The original vacuum former video was at the old place. 👍🏼

[@SomewhatAbnormal]

I could be wrong about this, but I don't think I am ... a buck is actually the object you're vacuum forming around. So your wrenches and Raspberry Pi are the buck in this scenario. Padding is what you use to push the object away from the platen whether the padding is built into the buck or just stacked underneath. Padding helps to get additional material beyond the bottom edges of the buck, and also helps to avoid pinching on corners. Another note, if the heater is encapsulated in the box (instead of sticking out the bottom) the heat will be more evenly distributed across the material because it won't be escaping out the sides.

[@zaprodk]

FYI, Actually, your eyes are safe even if you have no battery in your welding mask. The UV-blocking properties is there all the time - it's just uncomfortable to look at.

[@mitchtaylor7725]

bright lights burn retinas too. Uv or no UV

[@kisssys5414]

Make the seal to the plastic itself, then you don't have to worry about the frame leaking and the clips won't get in the way. Adding a fillet at the bottom of objects will stop the spider webs. Also heating the parts to be formed can help preventing them from setting too quick and then setting them with a spray bottle of water.

[@seropserop]

Hey, I work as a Thermofoiling engineer and positive pressure vacuum machine specialist for thermoforming at a kitchen door manufacturing company, I can help you fix those problems you're having with the pinching and wrinkling along the sides of the objects you're pressing. There are also a lot of variables that aren't considered (like preheating time and your shop vac ramp up speed while forming) in this build I can help with to make the outcome perfect just send me a message

[@YouCanMakeThisToo]

I'd bet Bob is interested, but if you listen to his podcast you know his time per project is extremely limited, this one is done and he probably doesn't have the time. But the spirit of this channel is teaching, sharing, and learning together. Whether or not Bob has the time to personally reach out to you, there are tons of people here who would love to learn from what you know. Unless you're only interested in helping Bob, then none of that matters.

[@originaltrilogy1]

Well, I guess because it would benefit everyone in the maker community to share your expertise. Pretty much anyone who took the time to watch this video would be interested, and certainly anyone looking to build their own machine. These channels are all about sharing information and gaining knowledge, so it wouldn't be a waste of time at all, I reckon just telling Bob the info would possibly be more wasteful, as the information might not end up going out to the wider audience. I hope you can take the time, as I am genuinely interested.

[@chikakitagawa5134]

seropserop I kind of feel sad for you

[@crazyminecrafter14]

Just a tip, if you use thinner wood, make some supports for in the middle, as it is possible to implode your box (this happened to mine), when you create the vacuum.

[@Hanakooh]

Now that i thought of it, you had done similar remakes of previous projects. This one is remaking the smaller and simple vacuum former to be bigger, but there is also an ON AIR light sign you made long time ago, and you upgraded it with an LED panel sign that runs on Raspberry PI. And also that longboard out of wood pieces stuck together which you later made a better one with a stack of veneer and a vacuum form, and even later a DIY trike. Really excited to see all these old projects turn into their 2.0 version!

[@davidmarr5245]

I built a small one using pegboard and it does ok, I look forward to making one like yours. Nice job!

[@KahBooom]

For the MDF box with the heater, I'd recommend lining the inside of the box with some high temp aluminum foil tape, or even some engine bay high temp paint to help a little more to prevent the mdf from getting overheated and will help disperse the heat better as well. As for getting the full piece of material to heat a little better evenly, build another small frame with aluminum foil tape lined on the inside in the space between the heater box up top and have it go down to where the top of the metal frame would magnetize to the magnets.

[@TychoCraft]
