When our shredder, here in Lyon, will be ready (before September), I’ll be free to test all this! I’ll come back to you to give our feedback.
PC (Polycabornate) glass transition temperature: 145°C, it means it is already under its glass transition temperature when at room temperature if I’m correct 🙂
Making it more brittle would help for sure, but maybe only with PP (glass transition temperature 0°C or -20°C). It would be also difficult to cool the system (how? impact on bearings?)
In some home appliances, it’s quite common to have plastics reaching 50°C or slightly more and it remains stiff enough (for example: coffee machines). I should check how much it affects the mechanical properties.
Finding a smaller motor is easier and using a simple hair dryer would be fine I suppose but it may require more power in total, you’re right.
Have you managed to improve your system? Have you tried a flying wheel as Dave advised you?
Keep us informed!
We have exactly the same goal here in Lyon, to build the shredder first and then the extruder.
Here is our homepage and our facebook page: http://www.wewaste.fr and http://www.facebook.com/wewaste
Our biggest challenges right now, to make the shredder, are to find the motor and how to cut all iron parts.
Here in Lyon, we haven’t found any Fablab which has laser / water cutter. Maybe we could cooperate to reduce costs for this cutting operation?
Small change, big difference … just by changing the salad dressing it can change everything for example.
There are ingredients that are essential for me to always have at hand’s reach on your shelves:
– Garlic, Shallot, red onions
– Various type of oil (Olive, Sunflower, walnut…) and vinegars (Cider, balsamic …)
– Big variety of spicies, herbs, blends (Zaartar, Gomashio …)
– Soya / Oyester / Worcestershire / Tabasco sauces
– All kind of nuts and seeds, dry fruits
– Honey(s), Mustard, pesto …
I am sure there are a lot more stuff you can add to this list but with that you can do magic 🙂
Don’t you get bored to always eat that?! 🙂
Boiling your water with an electric kettle would save even more time 🙂 You’d still have time to chop the vegetables while the egg is being cooked
