To get better pressure distribution when pushing over the mould, put the plastic sheet in a wooden frame. I have two vacuum forming machines and it works much better.
@ No, for something this size, make two identical frames out of 1/4” thick plywood. Sandwich the plastic sheet between them, use the big black paper clips to hold the frames together trapping the plastic sheet. Once you heat up the plastic as Tyler demonstrated, quickly push the plastic down over the mould, far enough to just go beyond the edges of the dome mould.
@hotlapkyle ahh, I get ya, I was also wondering about a similar method akin to how they mold kydex for holster. Basically you heat the sheet till pliable, then use a dense foam mold, clam shell style, and fasten it together under slight pressure while the plastic cools. Then remove and trim. Thanks for this vid btw, I have had some FPV ideas for some time but had no idea what to do as most of them would need domes or lenses that aren't already on the market. This would help and gave me many ideas for solving the issue.
PETG has a melting point of 260 degrees Celsius (500 F?). For 3D printing you would put your nozzle between 210-250 degrees (410-482 F). If your oven is able to handle those temperatures then put your sheet on a flat surface in the oven. Start with the lower temps. From there mold it around your cone. Also, cut out smaller parts/squares of the sheet first. Then try one by one which temperature works best. Smaller parts is much easier to work with.
I would love to build one of these, but I have absolutely no experience with printing or RC hobby but it looks super fun to build and fly Any helpful tips on getting started would be appreciated greatly I don’t even know where to buy any of the stuff
@rodgermoore0007 th-cam.com/video/EWt0yWP4a9Q/w-d-xo.htmlsi=1pOOj3yQ2ctQ4AN4 this is made from wood, but you can punch a bunch of holes in an shoebox as well.
I'd be curious to try a similar but tweaked process for the assembly: have the clear dome part sandwiched between two socket pieces to trap it there. And also the making of the drome process, it'd be interesting to print a sort of jig setup to streamline the process if it was going to be made in series. But so far, it's still very cool & visually pleasing
Do you mean the Stryker flying wing, if so I’ve had one for years and this could be its next evolutionary step now that it grew a EDF on the back. Dang I forgot how white knuckle that thing is to fly, maybe not in the nose, can’t count the number of times I’ve created a new one out of furniture packaging 😆🤣😂
That’s… really barebones way to do it… Especially if you already have the luxury of a gas oven… The pet need to be held in a frame on the 4 corners. (Sandwich it between 2 identical frames). Warm it in the oven until it droop. Then Either use a makeshift vaccum table or a heatgun to adjust the conforming.
We all know how a vacuum table works. You are overthinking it though. Why go through all of that extra hassle when the center 2 inches conforms perfectly without it?
@@JanoschNr1 It's definitely an American thing. People are very attached to their gas ranges, for some good reasons and mostly not so good (i.e. incorrect) reasons, in my opinion.
Why not use a heatgun? Thanks for the video and method!
One of my favorite channels. Grassroots development where ideas are key and the sky is the limit. Happy New Year.
Thanks for sharing this video

Question jdutkoski2303, have you drilled holes on ""mounting plate "'so it pulls plastic sheet down around Plug ?

What if you just set it on top of your mold, and then use a heat gun until it droops down and takes the shape?
@@keem5143 I did try but you need 3 hands

Can’t wait to get the files for this if you’re willing to put them out!

Put the sheet ina frame and push with parallel even pressure
Thanks for the video. What’s the deal with the tiny cybertruck?
cardboard box + duct tape + wacuum claner and you got youself a waccum table, place mould under the sheet and use a heat gun from above.
pic or video?

how have you not set up a panel to vacuum form this, since you did every other part of vacuum forming?

I have used a microwave dozen egg tray and made 9 at once
This is great thanks! 👍 I went to amazon looking for PET sheets and found doggie pee pee pads lol

@@G_de_Coligny yes if you have the tools and knowledge that’s the better way. This is the quicker dirty way for people building the new plane

Hot air guns exist, just sayin
most homes have ovens with stove tops though out of luck if it is a modern stove top
@@greygunner Well must be a american thing, as in the EU those are a rarety and modern stoves are everywhere
