At Last one that makes sense to have the heat below the plastic rather than on top. At least this way you use all the heat as most built one forget heat rises. Great job
Yes ! can be used around bottom edge as the vacuum pulls the sheet into place there is a lot of wriggle room with this build about 20mm extra height at the bottom of plug so the PETG sheet pulls past the wanted edge, use small blocks away from and opposite corners that form a ridge. Use talcum powder as a release agent on the plug, the plug must be very smooth oil covered plugs create bubbles. I use balsa and hard foam plug, pull one canopy cut it out leave in place then pulled over the top.
I used PETG known by many product names such as VIPET by Mulford Industries. Ordered mine locally from a plastics forming supplier. Comes in sheets 2400mm x 1200mm .75mm thick for around $80. Several thicknesses are available, for my purposes .75mm is ok.
you could built a pressure switch on the edge of the heater. When the frame with the sheet is on the heater it will start to heat up. When taken away the heater will stop.
These are two oven elements from old cookers 240v AC direct wired to two 10amp light switches at side so one or both elements can be selected, a safety earth is incorporated and all enclosed - I used the wiring from the cookers. Wired in a 3 pin lead for wall socket. The tin frame is from the cooker back plate with pine board sides. Its not on long so not heating up much. Downside is heat focuses on the centre of sheet and edges are a bit cool, need to heat edges of sheet.
Ozzie, Good job. I gather it was your first attempt. I made something similar before I researched it. I will vid mine when I have the system set up correctly. PETG is porous believe it or not so make a top for your heater box (or use an oven) I use a piece of ply covered in foil. PETG needs to sag at least a couple of cm's before moving it quickly to the plug. A heat gun set to 180C gives best results applied directly after you place the sheet. Point it into the corners you need extra attention on. If you can heat your plug to about 100C this also helps. don't turn on the vac until after you have placed your PETG. PETG will pick up any inconsistencies in the plug to 0.01mm so talc would not be a good release agent. I would use a car polish or fibreglass wax. There are hundreds of good videos on how to do all this.
you look like good ! make a video of your technique with the heat gun ! I use A4 sheet for cover file !! the result isnt bad but I have sometime some folds in corner
I watched your vid again and it occurred to me that you might be able to make a vacuum formed canopy over the original molding and then using it's smooth qualities make ANOTHER vacuum formed canopy over that and the optical qualities might improve further. Nice styling in your plane, by the way.
Fascinating, and very informative, thanks. What's the maximum thickness of plastic you can form using this method? I want to make a protective cover for something, and would ideally want to use 3mm thick plastic.
brilliant piece of work!! my frames will be build before night what kind of vacuum pump were you using Also what thickness plexiglass were you using? and where do you get it in Australia?
Yes the optical quality is affected but not a lot it depends on the form used, commercial methods use polished aluminium I believe. This method is ok for my needs in aeromodelling. Don't know - only used .75 mm thick PETG but I think it will handle thicker, difficulty is the centre gets hotter, and getting the edges warm enough, I use a heat gun at the edges, forming this way will show up every speck of dust or hair on the form or sheet.
Just a suggestion about the heat distribution problem: try lining your heater box with alluminum foil to reflect the heat around the box equally rather than let the coils focus it upwards.
hi, i have also a vacuum just like yours, but my plastiek canopy is not so transparent as the original. there are here and there some tiny air bubbles in the plastic after vacuum draw. Do you have also that reslut? I think I should experement with other plastic ...
NICE VIDEO !! but how can i make a heater box like yours.. can you please tell me how to connect the wires, etc. to the heating elements.. Can you please tell me.. or a video of making a heater box would be nice to..
That was done very neatly. Nice home-built vacuum kit you have. DId the heat or other activities affect the optical qualities of the plastic sheet that you used? 2nd Question; How thick can you can with the plastic to get accurate forming? Thanks. Sydney.
Hi! I'm impress with your set up!!! I'm interested to learn how you wired up the heating elements. And if you used the controls from and old stove.Hope to hear from you soon!
Please, Please, Please, how would you like to make a windshield for a Dave Patrick Cub? They are not producing planes and this is something that no one is making. One guy did, Aerotech, but I called him today and he said that someone bought all his stuff. I know there are about 3 or 4 other guys looking for these windshields.
You are entirely too big to fit inside the glider. So I must assume you are going to put squirrels in the glider and let them fly around. I would recommend flying squirrels they have a lifetime of experience at gliding. They would make the perfect pilots for your glider.
Excellent work, clean and beautiful, thanks for the demo

Thanx for Your video, to me it was very helpful! Nice work.
You make this look so Easy 👍👍

nice work ozz
Would love to know what the plug is made of and what surface coat you applied. Also, please, whether you applied any wax to the plug? Thanks

heating plastic isnt dangerious? by the way what sheet u using to make the canopy

Very nice, where do you get the plastic sheets, If i was to order some, what do i need to look for? Best regards
Good job i want this machine
awesome but where do source your plastic sheet?
Hi, how did you made the canopy base for the plastic? Very nice machine...=]
Just a suggestion about the heat distribution problem: try lining your heater box with alluminum foil to reflect the heat around the box equally rather than let the coils focus it upwards.
Can i know what type of plastic sheet you have used and thickness :)
hi, i have also a vacuum just like yours, but my plastiek canopy is not so transparent as the original. there are here and there some tiny air bubbles in the plastic after vacuum draw. Do you have also that reslut? I think I should experement with other plastic ...
what kind of plastic how thick, and where do you get plastic that size?
What kind of plastic sheeting did you use and where can it be bought?
Please, how do you make the PLUG???
great job
which materials have you used for the vacuum?? thank you
hi there, my husband would like to know if you could possibly make a canopy for the Lunak for him, and if so how much would it cost, many thanks.
Does the finish product no craters or pin holes?
How much temperatur for melting glinder canopy?
where do you get your plastic sheets?
Wow i really want to do this now!
What material is that sheet ? PTEG OR LEXAN?
Wait this site only ships to UK? Because im very interested.
NICE VIDEO !! but how can i make a heater box like yours.. can you please tell me how to connect the wires, etc. to the heating elements.. Can you please tell me.. or a video of making a heater box would be nice to..
thanks a mill great video great skill
How did you do the mold?
where can i get the plastic?
HELLO PLEASE!!! WHERE CAN I BUY THE MOLDING SHEETS WHAT IS THE BRAND OR NAME
From Australia actually - South West corner of WA, (we escaped from the UK 200 years ago .......)
I don't think escaped is the word you're looking for
Does clear PETG turn white when over heated?
That was done very neatly. Nice home-built vacuum kit you have. DId the heat or other activities affect the optical qualities of the plastic sheet that you used?
2nd Question; How thick can you can with the plastic to get accurate forming?
Thanks.

Did you get a reply on how to wire up a vacumm heater box. If so will you share it with me please.
Nealeg
What thickness PETG did you use for your canopy?
He used .75mm thickness.
DE QUE MATERIAL ES EL MOLDE ROJO??
Music by Donna Summer - I feel love... ;)
How did you make the form/mold to vacuum on?? I need to make a new canopy for my 3.75 wik speed astir..
Carve it out of wood.
Temperature?
Can you tell me what plastic to use, I am also in Australia.
wow nice one bud
bonjour comment sa s'apelle les neon qui chauffe
When you turned off your heater the vacuum revved up :)
Looks like it would be hard to fit in that thing! Nice vid though.
Awesome job, How did you make your oven? Is it like making a foam cutter or is there more to it?
Isnt this song from like the 90s?
what did you use for the mold?
Nice Video. Thanks. Do you know where I can find plastic sheets online?
Iman Sadeghzadeh home depot has them near doors and windows isle
I've heard of people getting good results by leaving the protective film on.

Legal interessante ,amigo vc comentou no meu canal tô disponível pra trocar ideia.
What part of Australia are you from Ozzie ?
Please, Please, Please, how would you like to make a windshield for a Dave Patrick Cub?
They are not producing planes and this is something that no one is making. One guy did, Aerotech, but I called him today and he said that someone bought all his stuff. I know there are about 3 or 4 other guys looking for these windshields.

It’s a glider yeah? So what the fu....... is on the nose? Eh?
what kind of sheets did you use?? thanks and Nice job.
