I only found 4’ long pieces on Amazon, you will need to buy 4 to get the total length you need. Also I recommend making your frame a little smaller than 24” square to save on aluminum. Cut the raw material into 2’ segments, then cut the miters on the ends. Assemble the frame, then build your platen to fit inside the frame.

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.

[@ryananthony4840]

How thick of material were you doing?

[@KiEuKiTo]

​@@ryananthony4840He's still measuring.

[@misterfixit1952]

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.

[@barrylitchfield250]

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.

[@jennifermeaker615]

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!

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!

Fantastic tip Alex!

[@lawsonroesch101]

I am making one for the first time what do you recommend

[@MarkWarbington]

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!

[@punishedprops]

Great addition Mark, thanks!

[@evilutionltd]

No way you are losing any vacuum through MDF.

[@vasili1207]

That is not possible as mdf is gas tight. As it's a compressed fibres impregnated with its own binder. as. Really shitty advice doctor mdf

[@cohode6290]

You are absolutely incorrect, MDF is extremely porous and will not hold a vacuum, try to make a vacuum camber with an MDF lid, you will find out how porous MDF really is.

Thanks for watching! We're super glad you found it helpful :)

[@thefunbot]

nice job!! when the last run hit the mold i was so impressed!

[@skuffle5309]

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

[@IDMTB3D]

you need the distance to distribute the heat more evenly to the corners

[@punishedprops]

Thanks for the tips!

[@dolfinmagikpro]

@Brandon Winters - Wouldn't putting a small fan to circulate the air help alleviate this issue? Just a thought.

[@chrislinda3623]

​@@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.

[@christopherknerr2851]

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 :)

[@drwhoweigs]

That final piece very MST3K :)

[@cristianpaulmartinez52]

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

[@EthanfromEngland-]

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.

[@punishedprops]

I get what you mean. Probably a down side to the way I built this frame. It stops at the platen.

[@bigbadmanjocko]

You just need a shallow spacer under the buck that's smaller than the buck so it has some undercut.

[@colinfindlay4790]

@@punishedprops Adam Savage has the video you need :-) kzbin.info/www/bejne/eZLGo2SNmrCCsLs

[@drewpickard554]

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

[@Ainsy1970]

Regarding heat. It rises and will always try to equalise. Life can be hard enough without fighting nature too.... Underside heaters and good insulation is definitely the way to go.

[@BuckJolicoeur]

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.

[@SoRadAwesomeStCool]

Your mother-in-law needs a mask? Mine came with her own!

[@browndyt]

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.

[@punishedprops]

Very cool!... or... HOT!?

[@brettaylor2661]

wow. I never knew about this. I've been a tig welder a long time and always recommend welding as a last resort. There are so many ways to join things without distorting them like welding has the potential to do. Thanks for the tip on the deal.

[@badad0166]

5 years later. The Garage 54 team bought one. I watched them unbox it and pull door skins. The trick they have that you don't is a vacuum reservoir launch system. In your setup, the shop vac would void an inline series of pipes or a tank ahead of the table. A dump valve would release a super duper initial suck. Your plastic is farther away and upside down in comparison to the commercial ones. A little closer to the flame might do the trick. But it's five years later.

[@MrMonk052798]

The hot box

[@14Mew]

Bill you might think about adding some wooden handles on the sides of the frame similar to old metal pans. That way you don't have to worry about gloves

[@punishedprops]

That's a pretty fantastic idea!

[@startide]

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 !

[@wilwrk4tls]

I very much like the build! I'm moving soon and will finally have room for one in my new workshop space. 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.

[@punishedprops]

Great tips, thanks for sharing! =D

[@banddboy]

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.

[@punishedprops]

We're really glad you found it so helpful!

[@jones1618]

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. Name ideas: Ooie-gooey Prop Drop, Shape Sucker, Fantastic Elastic Plastic Press (FEPP)

[@punishedprops]

That's a pretty great idea!

[@jones1618]

Another suggestion: You might get more even heating if you added a PC muffin fan inside to create internal convection (not to draw in or exhaust air).

[@dougsundseth6904]

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-)

[@punishedprops]

I've considered it, but I've never heard off anyone else using a fan for their vacuum former heating elements. ¯\_(ツ)_/¯

[@dougsundseth6904]

@@punishedprops After thinking about it for a bit (like you do), If you were to keep the motor out of the heated space and just run a shaft through the wall with a metal-bladed fan inside, you could probably use inexpensive components. 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-)

I jumped in here to say the exact same thing. All he's doing there is wasting the initial heat (electricity). Yes, I know it's been two years...

He was concerned with getting an even temp across the plastic at all times. I agree that pre heating wouldn’t be necessary but if you wanted to, I’d make a temp cover to improve efficiency

[@sansker423]

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.

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.

Lastly at least in the US most electrical code requires receptacles to be wired with 12g wire on a 20amp breaker. Only lighting circuits should on 14g wire with a 15amp breaker.

Excellent video for the Softsuck 2000!

Great job! You'll get even better definition if you heat the negative with a heat gun or blow dryer. It will help negate some thermal diffusion from the plastic to the negative.

Regarding the vacuum on/off, always handy to have someone hidden behind the counter, but a foot switch count be a nice addition!

You could also use rivets for the platten frame.

Thank you for the awesome tutorial. I'm not sure how you prepped the sheet metal but you could emphasize that preparation is key when using adhesives. A lot of times they use a protective coating or even petroleum on the sheet metal so I usually clean it really well with 91% isopropyl rubbing alcohol and then I'll lightly rough it up with some 220 sandpaper. Thanks again I'm looking forward to building a table for myself for forming and laminating wood.

So glad you enjoyed the video!

I love how "sci-fi" themed has become simply just a bunch of random objects laid out in an orderly pattern... I love trying to find super common things like flashlights in sci fi scenery, they are all over the place!

Cool and educational video, thanks for posting.

I heard Bill refer to the heater portion as his "Hot Box". Nicely done.

Hole saws are a wonderful thing.

[@beardedgremlin8117]

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

'The Privacteer.' cool demo, thank you.

[@punishedprops]

Thanks so much for watching!

Great video. I wish I had a space to do this. I'm working on the itty bitty former now. Got me a really nice large size toaster oven yesterday for $.69 / lb which came to about $11. Still need me a 2 gal shop vac.

[@scottshipley9230]

I worked in a modeling shop in the 90's and we built our own oven and vac table...for better definition on fine details, perforate the object being formed, especially the deep central cavities. Also, have the vacuum arrive before dropping your frame. Nice work!

Thanks so much!

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.

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

[@VeradonaRestoration]

Wow, good idea, Thanks !
