So far still only preliminary exercises.
To see what I'm working towards building see the Freeranger info page I Handcarved a roughly 1:3 scale foam plug of the bottom section of the car yesterday to do a test of the process of foam shaping, coating, glass laying,resin, maybe body filler and sanding, mold release and negative and positive molds. Also to eventually gain some insight into the twist stiffness of the hull and how many layers of fabric is needed to gain the necessary strengths. It's 120cm and 30cm wide which is a little less than 1:3 scale. The height is 1:3. A couple of weeks back I got the motor from Ebay (350$).
I ordered a Skyway Tuff Wheel II 20" carbon fiber reinforced plastic wheel originally from the BMX world (100$). The Lincoln Leadership Project at Gettysburg. Reciclar poliestireno extruido o styrofoam. Www.EPSFoamPro.com. Ecovative Design. 3. DISOLVIENDO POLIESTIRENO EXPANDIDO EN ACETONA. Invention of Polystyrene and Styrofoam. Polystyrene is a strong plastic created from erethylene and benzine that can be injected, extruded, or blow molded; making it a very useful and versatile manufacturing material.
However, do not forget to recycle polystyrene products. Most of us recognize polystyrene in the form of styrofoam used for beverage cups and packaging peanuts. However, polystyrene is also used as a building material, with electrical appliances (light switches and plates), and in other household items. Eduard Simon & Hermann Staudinger Polymer Research Polystyrene has a long history of evolution behind it. It took another German, organic chemist, Hermann Staudinger, to realize that Simon's discovery, comprised of long chains of styrene molecules, was a plastic polymer. In 1922, Hermann Staudinger published his theories on polymers, stating that natural rubbers were made up of long repetitive chains of monomers that gave rubber its elasticity. How to "make" plastic. How To Recycle Plastic At Home. How is Polystyrene (styrofoam) Made? Convierte la UNAM unicel en pegamento. Hotwire Foam Factory. Custom Trim Molding. Crafters Cutter 6 Inch Hot Knife.
FCX448 Automatic Foam Cutter. Tutorials. Hot Wire Foam Cutter. Rocket Team Vatsaas Hot Wire Foam Cutter. I built this tool because I needed to develop a way to shape a big block of Styrofoam when I built The Happy Birthday Party Napkin Rocket of the Apocalypse.
The photos here are from that project, but I've utilized this concept in the construction of a variety of items. Consumer Product Design - Cordless Heated Foam Cutter. Our client identified that the cables leading from heated foam cutting hand tools somewhat limited their use, especially around larger models or sculptures.
We were asked to design a cordless unit with a range of accessories. By analysing current products and performing user checks, we were able to identify areas for innovation. The design of the over-moulded case was challenging along with condensing the electronics into a small package taking into consideration all the safety factors. Challenges... Guitar String Hot Wire Cutter. Before you build the frame, you should test your wire.
It doesn't need to be taunt to test its heating capability. In this case, I hooked the wire up and attached to it a power supply. Lets talk about the power source: Ideally you might have a variable DC power supply. In my case pumping 11.1 Volts @ 1.7 Amps did the trick. Varying the voltage will change the current. If you don't have a power supply you should get one, they are very useful. Hot Wire Foam Cutter Calculator. Here is a link to my new instructable Design Charts I made this hot wire calculator because I got tired of frying ac adapters (transformers) or burning out hot wire's all the time and no way was I going to buy an industrial hot wire cutter!
