  • RC Vacuum forming plastic bodies etc

    this topic i find very interesting and im seriously toying with the idea of making my own setup, tons of videos on you tube to show how its done and it looks quite easy to do

    the main thing is


    where the heck do you buy the plastic sheet???

    i found this on a web site

    Plastic suitable for vacu-forming is very easily found. The most commonly used is polystyrene, which is what milk jugs and many other household goods are made of. Other types of plastic can be used as well, such as polycarbonate (AKA LEXAN), ABS, PETG (2 liter pop bottles), etc. These all work well for vacuum forming.

    These plastics can be found in large sheets and varying thicknesses from local industrial suppliers, or online. Local big box type home improvement stores usually carry some plastic as well, most often polycarbonate, and polystyrene. Cheap light diffuser panel

    The polycarbonate is usually carried in small and large sheets from .06 to .08 thick. The polystyrene sheets can be found being sold as "light diffuser" panels near the overhead lighting section.(these are the textured panels they cover flouresant lights with.) The light diffuser panels are a good source of cheap plastic to practice vacu-forming with, however they do tend to be very thin.



    does anyone have their own plastic former? can anyone shed some extra light on the topic?

    thanks

      well so long as you have one to clone , or you can make a mould from it with plaster of paris then your cooking with gas

      if you look thru my favorites on my youtube channel you will find a number of videos on the topic and its pretty simple to do

      http://www.youtube.com/user/TheStinger30#p/f

      whats holding me back at the moment is the lack of the plastic used to put in to the moulding machine to start with

      the reason i want to build one of these devices to to make my own rc bodies

        some tips on using plaster of paris as well. use plaster of paris to make a permanent mould and then vac form away till your hearts content

        http://knol.google.com/k/how-to-use-...f-paris-molds#

        the most important bit is to smear some petroleum jelly (Vaseline) around the inside of the mould before you put the paster in to allow easier removal once dried

        copied/paste here for future reference

        Plaster of paris is a fun art medium that can be used to make a variety of home d?cor and garden d?cor items. Whether you want to make magnets, patio stones or prints of your little ones’ hands and feet, plaster of paris is an easy way to make molds and casts without much hassle and a minimum of mess. Plaster of paris is made from powdered gypsum, the same thing that artists use to prepare their canvases before they start painting. The powdered gypsum changes easily from a liquid to a solid when you add water, making it far easier to use than powdered cement, for example, or even paper mache when you want a quick and easy craft project that is all your own.
        You can create unique and beautiful pieces of art using plaster of paris and other artistic media.
        Before you start out with your molds and your casts, you need to prepare a work area. While plaster of paris projects are fairly easy to contain, the powder can puff up and spread if you are in drafty or breezy location. If you are going to work outside then this probably will not matter or even be particularly noticeable, but if you are working inside it can be a big problem. Make sure that you are in a well ventilated area, but that it is not drafty. Also, cover your work area with plastic or newspapers. If you will be working with small children, then you should probably tape the newspapers down to keep them from sliding. Wear old clothes since you may end up dripping some plaster of paris on you. It will wash out, but it is still better to do this kind of art in “work” clothes rather than your best.
        Next, make sure that you have everything that you need on hand. You will need molds for your plaster of paris. They may be artistic molds, molds made out of plaster of paris – we will talk more about this later – or even candy molds, which make great casts for magnets and small decorations. You will also need paper towels, a mixing bowl, sandpaper, a knife that you do not need for cooking and petroleum jelly. Wipe out all the molds to make sure that they are clean and dry, and if you are using plaster of paris molds then coat the inside of the molds with a thin layer of petroleum jelly to prevent the old plaster of paris from adhering to the new. The petroleum jelly will create a seal that will enable you to turn out the cast once it has set. If you are new to using plaster of paris, then start out with smaller, manufactured molds. As you get used to the medium, you can make larger and more elaborate things.
        The same molds that you use to make sweet little candies are also good for making small plaster of paris projects.
        Mix the plaster of paris with cool water. Follow the directions on your specific container of plaster of paris since different brands require different amounts of water and mix. The cool water will cause the resulting mixture to harden more slowly, which will give you a little more time to work as you pour your plaster of paris into the molds. Your mixture should be about the consistency of cake batter.
        Pour the plaster of paris liquid slowly into the molds. If you pour it too quickly, you will trap air in the bottom of the molds and you will lose many of the fine details in the casting. Make sure that the liquid gets into every nook and cranny of the mold. Once you have filled the mold almost to the top, tap it on a hard surface to get all of the air bubbles out of the mixture. You can rap it fairly hard, but be sure not to jostle the mixture or you will end up with a big mess. Hold the mold firmly in both hands while you are tapping and be sure to keep it level.
        Let the plaster dry. Some small molds may need as little as ten minutes, but to be on the safe side you should wait at least an hour before you try to remove your finished plaster of paris project. If you remove it too early, there is no way to go back and get the wet or broken parts out of the mold in one piece. You will just have to start over completely. Keep the mold and its contents in a warm, dry place while they dry out.
        When you are ready to pop your mold out, twist the mold to loosen the edges of the casting from the mold. It is similar to popping ice out of ice trays. Obviously, if you are using a mold made of plaster of paris, this will not be an option. You can use a knife to loosen the sides of the mold and to make it easier to get the casting out. Do not use a sharp knife for this since you will likely break the tip off.
        Once your have gotten your plaster of paris cast out, it is time to put on the finishing touches. Use the sharp knife you got out earlier to cut off any “seams” that may have slightly overlapped the top of the mold. Use the sandpaper to smooth the bottom of the figure so that it sits firmly and flat on the ground. Now, you can paint your figure or decorate it in any way that you choose.
        If you want to make molds out of plaster of paris, simply get a large container like a bucket or a tub that the figure that you want to make a mold of will fit in. Fill the tub with plaster of paris, then push the object into the plaster of paris. It should not have hooks or bends that will make getting the object out without breaking the mold impossible. Once the plaster of paris has dried, you can remove the object, then coat the inside of your new mold with petroleum jelly before filling it with more plaster of paris to create a replica of the original object.

              dont have any in stock, they order from brisbane every 2 weeks.the guy i spoke to said that if i made a cast out of plaster of paris it probably wouldnt last too long.reckons id be lucky to get 12 runs out of it before it broke.thats cool. i can live with that.

              so.just need to find some peg board.i have just about everything else i need and i can make my own vac form machine....yee-haw

                      [QUOTE=devil rider;586966]Hi Z

                      you are going all out hey!

                      What style of body do you currently run & what will you try to achieve?


                      i have an erevo body 1/10th scale ( more realisticly its 1/8th)

                      http://www.google.com.au/search?aq=f...w=1920&bih=964


                      my main reason to do this is for myself to save some bucks on new bodies. being a basher, bodies dont last too long, and funny enough when your doing 40kmph and you flip it on concrete or tar, bodies wear our very fast...lol

                      what id like to do is buy a brand new body and take a plaster of paris mould from it and remove the plaster and keep the new body and put it aside to make new plaster of paris moulds

                      i can then use the plaster of paris as the mould to form new bodies.
                      if i buy a sheet 2440mm x 1220mm sheet cost $41 then i need to cut smaller sheets from it about 600x400 to cover the erevo body and have 100mm gap around the edges
                      this would give me 2440/600=4 and 1220/400=3 so 12 bodies per sheet
                      so $41/12=$3.42 per body as apposed to $32 + post
                      http://www.ultimatetoys.com.au/traxx...1-p-11454.html

                      i have no intentions of making these and selling them on ebay or the likes, just do it for myself

                      however

                      someone mentioned earlier about pop bumpers, well im sure i could help out there too

                        i did find a great DIY one in the usa on youtube and i added it to my fav's. it uses 2 air rams to move the heated plastic up/down on to the mould. very smart.they made a ghost busters logo with it.

                        pitty im working this weekend or i would make a start on building my own vac former

                          starting to collect parts for this.i will build at *least* 2 different sized formers. one will be big enough to fit a plastic disposable plate onto it for small stuff (like pinball pop bumpers) and a larger one for my rc bodies

                          im chasing peg board and a decent sized workshop vac. i have put an advert in our local free cycle and see how we go
