Hey Bill, it's been a while since vacuuforming for me (worked at a sign company). A little tip: at the end of the vacuum draw, if there are some imperfections where the vacuum didn't pull all the plastic, use a heat gun to reheat the plastic as the vacuum continues to draw. That should fix it.

​@@ryananthony4840He's still measuring.

Although you are heating the plastic (to be formed), you also need to heat up the area around the form and vacuum table. As soon as the hot plastic hits the cold form and table it quickly looses heat and looses detail, thus the webbing around the bottom of the mould. Use an infrared bulb (or two) over the vacuum table to preheat the bed and form.

2 years later and this video is still worth it. For your heater( you may have solved this long ago), I volunteered once building an Open 60 sailboat, they used prepregged carbon fibre/epoxy. The autoclave they built covered the whole boat and they used refective styrofoam panels with minimal wood framing. Worked like a charm! Loved the video and the trouble shooting process. Thank you!

Thanks so much for watching and for the tips!

That was kind of difficult to watch. Several years ago (~40 years) I set up a vacuum forming operation for a company that used thousands of parts made on vacuum form machines. Seeing you struggling with starting from scratch to build a vacuum forming machine was hard to watch. All of the things that didn't work, and needed to be fixed, were very common when you're first learning about vacuum forming. I was glad to see you finally pulled a successful batch of parts. Good luck on your continued adventures in vacuum forming from the ground up. A good, wholesome video you made. It showed the good, the bad, and the ugly of starting to learn a new skill set.

Dope! I love how you showed your trials and errors, and talked through the various issues and possible solutions, etc. Super cool to see the realistic process, and appreciative that the time you put in will save us time when we take this project on. Thanks!!

This was actually very handy for me as im a younger diesel mechanic and i have loads of tools and this was a perfect way for me to make custom tool organizers for all of my tools even the oddball ones i own and so far its working perfect i just used black plastic and it was slightly thicker for durability. I also made a couple tool trays for a couple other guys in the shop and they love it so far! Great idea. Been trying to solve this problem for a while!

Hey Bill. Just one critique for you. MDF is porous (you can actually pull a vacuum through it) so you're probably losing a lot of your vacuum potential to the underside of the table. Just give the bottom and the sides a coat of polyurethane and that will seal it right up. Good luck!

Couple of thoughts on the machine, As far as tripping breakers stuff usually draws the most amps at start up so doing what you did and starting one at a time is a good idea and point to make. I think the real thing with the overhead heater not liking life was the large gaps on top. If you had closed the top gaps and do aluminum tape on the inside I bet it would of worked. Also you might want to think about getting on of those foot on/off switchs for the vac

wow! thank you i remember seeing your video about the small vacuform & was excited to see this be done

Awesome build. Glad you stuck with it

What a fun project! For the platen I would've done away with the mesh and added a ring on the elbow as a stop so that it doesn't go all the way to the top. This allows for a higher CFM since there's less air resistance. The other change would be to make your "oven" shorter so that there is less volume for the heaters to heat up alleviating some lost heat calories. Otherwise, great build :D

​@@dolfinmagikpro That was my first thought but you would probably want to get yourself an old or replacement oven fan. Catch being that most of the heat is radiant heat from the heat elements so your really only blowing around the secondary heat (from the plastic). Which is also why the "10 min preheat" probably isnt doing a lot. If you sit under those heaters its hot when they are on and cold when they are not but they dont really heat a room very well only surfaces they shine their light on. If you really wanted to spread the heat out changing the curve of the reflector would be the answer although probably a real pain. Making the curve shallower would enable the IR light to spread out more giving a more even heat but the foil box is probably doing similarly assuming you are far enough away with the box height. A V shape of mylar would probably give the profile you are looking for with the reflective box the rabbit hole is never ending. Those heaters are built to focus heat and that isnt really what you want but "modification is the mother of invention" or some such.

Why not use Mylar faced styro-insulation boards for the wall material? dual purpose as it would insulate better and reflect any radiant heat back to the center of the box. Just a thought :)

When casting its a good idea to pull past the object. It gets rid of the webbing ruining the result and means it can be cut off. Either be able pull past the table height or raise the master via a stand. Idk if im making any sense. Also I love the scifi panel idea.

Something we used to do a place I worked was put carpet padding under the master which let it pull vacuum all around. If there's a few more dollars to throw at the project instead of aluminum foil to line the box you could get a roll of Reflectix- it's great stuff and you'll bake the plastic in no time! You'll lose a LOT less heat. Also you could tape off unused areas and make a smaller vacuum area on the table to use with a smaller frame. Multiple tables in one.

Three things: 1: Use insulation around the box to decrease heat loss. 2: Add a plastic mirror (45 degree angle) to the bottom so you don't have to squat down for the IR Sensors. 3: Blow an air chuck into your form to release it.

Instead of bolting the aluminum frame together, using some 'low temp aluminum braising rods' would create a joint stronger than tig welded aluminum. and only needs a plumbing blowtorch. as a bonus it will also fill in any imperfections for those who do not have a metal band saw. There are several you tube videos showing how to use it.

Love this! a few suggestions though. if you put sharpened inserts (5-6) along the edges where the sheet plastic is, it will act as teeth and "bite" the plastic holding it tight. no need to screw and unscrew each piece to hold edges of plastic. also, if you drill very fine holes on edges of the shapes in the form you will get suction from inside the mold, not just the outside making better/crisper forms. you can then reverse airflow when set and the mold will pop/release. To get rid of webs, preheat that area before the oven with a heat gun. the extra heat in that area will help it form.

I suggest you throw that vac in reverse and invite me over for some air hockey!!

FYI: Highly recommend wearing at least a dust-mask when working with MDF- creates super fine dust that is terrible for your lungs.

Great build, great video. I haven't built one of these, I'm not an expert at this and I don't play on on TV, but I did think of a couple of suggestions ... here is just one. It's a bit complex, but not so much if you plan the build around it from the start: For the heater box: 1) Cut a slot in one side, about 1-inch down from the top, and for the full width of the box (yes, this would cut through your hinges but it could be planned for in a new build. The height of the slot should be about, but a little bit bigger than 1/4 inch, but see step 5 to plan the slot dimension. 2) Next cut 2 strips of wood, say 3/8 or 1/2 inch (square in cross-section), and as long as the inside dimension of the box. 3) Attach these 2 strips of wood inside the box, on the 2 sides adjacent to the side where you cut the slot, about 1-inch down from the top of the box. The top of the strips should be even with the bottom edge of the slot you cut, in step-1. 4) Optionally, an additional similar strip of wood could be attached in a similar way to the remaining side (the side opposite to the slot). 5) Prepare a piece of wood (Plywood, MDF, Masonite, ...). Logically this would be made of the same material as the material used for the box. The thickness will be 1/4 inch, but this piece of wood has to fit into the slot cut in step-1, so if using a thicker piece of wood, the height of the slot cut in step-1 needs to match. The width of this wood needs to be lightly smaller (narrower) than the inside dimension of the box. The length needs to be about 1 inch longer than the inside dimension of the box. 6) Optionally, cut a strip of the same material, about 1 inch wide, and the length of the box. Mount this strip about 1/2 inch above the slot, using a continuous hinge, or a few individual hinges, or interlocking screw-eyes and hooks. This piece should swing (pivot) to block or allow access to the slot. 7) Insert the piece of wood cut in step-5 into the slot and push it all the way in, until it touches the opposite side of the box. This piece will be a "lid/cover" that you slide in or out as needed. Now, when you use the heat-box, you can pre-heat the box, then place your framed plastic sheet on top, and slide the cover out, and you have full instant heat.

Cool and educational video, thanks for posting.

You still need the gloves to help the plastic push through as you vacuum it down... plus you are always at risk of touching the frame while handling the whole thing. Handles can help sure, but keep the gloves !

I think you could do without the extra screws if you glued a thin rubber gasket around the aluminum frame. That would grip the plastic better and more evenly. Also, if you regularly need to vac-form smaller pieces, it seems like you could just cut an adapter matte out two thin metal sheets that would clamp into the larger frame.

Awesome, dude! This was fun watching; great job!

“Acme Atomic Styrene Transmutational Energy Amplification Device”

Rather than using a purely radiative heating scheme, which has the unevenness problems that you ran into here, is there any reason you couldn't have added a fan and made this more convective? That would be a more even heat source and would have the added advantage that you should be able to keep the plastic below the heat source, which is less prone to ... letting out smoke ... and would also be much smaller, and thus more efficient. The big issue that I can think of would be sourcing a fan (and connections) that could handle the glass-transition temps you're looking at. This would assume that the fan lives entirely inside the box; if you were to put the fan outside, you would need to heat the inlet air as well as the chamber air, which seems more difficult to me, but might work. As an aside, I found it kind of funny that your shop has a spindle sander but apparently no large hole saws. 8-)

The hole in the wall of the oven wouldn't let out much heat, especially if it were kept close to the diameter of the shaft. (And you could even use a bearing at the wall if over-engineering is your thing.) 8-)

A couple tips from an aerospace tool maker / metal worker ... now retired. I am making these while watching the video so if you address something after I say it, good on you for seeing something and taking care of it! When cutting angle to make a frame, esp alum, simply notch the top there is no need to cut all the way down the sides, you just cut a "triangle" out of the top and bend the sides, less work and a stronger frame results. Tap magic... unless it is specifically for Alum, is not to be used on alum. There is a chemical reaction with the chloronated fluid and alum, bad things result. Center punching is good, nice work. Interesting use of window hardware! 1,2,3 blocks are GREAT to use for quick measurements! Those heaters should be radiant heat so if you made a closed box and made it deeper IE more distance between the heater and the plastic, you should get a wider pattern of heat. A heat GUN can be used to spot heat for better detail under vacuum. . In addition, a cover over the plastic will also hold the heat in, without a cover you have a large radiating surface. Over all score I would give it a 9.5 out of 10. Nice job!

I think the vacuum former looks like a Clyde.

Instead of the steel mesh, you use for the vacuum system, stick the pipes just like you would make a floor heating system. but group the above holes and place the pipes, one pipeline every 4-5 rows. also, join the pipes in each group into a single pipe. then fill between the pipes with a filling material such as silicone, liquid plastic, plaster or epoxy. After it hardens, remove the pipes. so you will have pipelines distributed into groups from a single pipe inlet. In this way, you vacuum the air in a controlled and equal amount. You put a lot of effort into making this video. Thank you for keeping us informed.

Nice work. I watched a vacuum form machine work. The big difference is the heat is kept on even as the vacuum is pulled to completion. The heaters were above the plastic and lowered evenly using cables and pulleys.

Love what you're doing. Just a couple of points about the heaters. They are infrared heaters. That means that they don't heat the air in the box, they only heat surfaces. So you don't need to preheat. White material reflects much of the heat away, that's why it takes so long to heat. Try building a 3"-4" deep box out of sheet metal to put over what you already have and paint the bottom of the sheet metal facing the heaters with flat black engine paint. That will turn the sheet metal box into an oven. You may need to put it closer to the heaters to get the temps you want but I doubt it since your getting close to your desired temp already. You will have to preheat it to get the sheet metal hot but it shouldn't take very long and it will be an even heat. It's pretty easy to build too.

Great video I wish that I had seen this years ago. I made mine similarly but I added strategically placed holes in the molds to allow more vacuum where the definition needs some help.

A great video, most diy videos are edited and only show things going well. You had the courage to shoot from the hip and included the mistakes. I've known for years that the only way to learn is through the mistakes we make, nice job and thank you.

We're really glad you found it so helpful!

I love it. Have seen how Bob from ILTMS did his with the heat from above. Also if you put something under it and lift ur master the corner creases aren’t right on ur cast but I love you guys stuff

Great vid! Adding a 6vac power transformer to the original 120vac would give you a 10% power boost, most probably enough to compensate for the borderline heating.

Thats pretty awesome! Just an FYI, you can weld aluminum fairly easily without a welder. You just need to heat up the corner with a torch and rub an aluminum welding rod in there.

Lol when Bill voiced the clamp he drilled into I immediately heard the chocolate bunny from last year’s Simpson’s Treehouse of Horror after Homer’d taken the first bite out of it. Loved the video by the way. Been doing a lot of vacuum forming machine research lately and this will definitely come in handy reference wise

That's fantastic! Good luck on your build.

I used to vacuum forming an RC body a few years ago, in order to have more details you should drill some holes on the panel you want to form, don't have to be too big, just make it 3 or 4 holes depending how big or wide your panel would be, just to help the air sucked not only from the side of the panel but also from the center. That would helps you get more details.

Suggestions and tips: Heater box: - adjustable height (adjustable heat, faster or slower heating), -single custom element (keeping in mind that this is a build of hardware store bought items, tear the two heaters apart and put the coils where you need them to be) Aluminum frame: -you can braise wield aluminum with a propane or map/pro torch (takes practice and a good torch head), -on the inner side of the frame where it grips the plastic put punch marks (punching from the sides that don't grip the plastic), all around the inner edge of the frame (making gripping dimples), or just puncture through the aluminum altogether with a nail or big punch to make gripping teeth -Also the aluminum frame was best idea, lightweight and cools faster The base: -glue the metal and spacers on before cutting for less work, or just don't cut the corners, -and primer or sealer or vinyl or veneer on any exposed MDF or particleboard (I hate working with the stuff and find that these wood like to attract ambient moisture)

I really enjoyed this video, you have real talent for props and for videos.

Thanks so much!

Name for build: Mind Melder, since it takes your collective ideas and molds them into place. =]

Great video! Sometime in the spring, (around May because my Michigan garage is unheated), I'm going to modify your design for a different purpose. I want to make a vacuum table clamp. I will use rubber, and a vacuum pump and install a ball valve. (plumbing). The idea is to put an acoustic guitar back inside, and vacuum the wood to scalloped braces while gluing, to create that violin style back. I think I will put a layer of plexiglass on the bottom of the MDF, to prevent air leakage. Thanks again.
