I think that it would create huge amount of dust particles which is not good at all. Alsothe plastic are not brittle so it´s hard to crush them they would be melting under the shear, but that is just my opinion, maybe I´m wrong.

Hi,
just to understand this, you are searching for schools to colaborate with or is this some kind of collaboration which is happening right now?

it´s seamless, so in order to be perfectly compatible with other components, so you won´t have to change anything the tube must be 34 mm outer diameter and 26 mm inner diameter? Thanks for the answer 🙂

The thickness of the tube has to be 4 mm? I can get 2 mm thick tube with inner diameter 26 mm for 5 euro. Thanks for the answer.

Hi everyone,
I´ve contacted more than 50 local workshops and everybody told me that they would make the screw I wanted according to the plans I downloaded from the website, so it hot me thinking how to solve that problem, I posted my question to our national machining forum and the answers I got werent very nice 😀 they basically told me that the the blueprint is total trash and that they aren´t surprised nobody wanted to make it for me, they told me I should start over and make a better design, but here is the catch, I´m total amateur, I can´t make new design, but I think that new design is necessary in order to bring the price down so that the screw could be cheaper, which would be really nice right? I can start to study the theory behind the problem but I don´t know how to use any software to make new design. Can someone help us with this? Or what do you think about that? Is that a bad idea?

The lampshade looks so great! I hope that I will be able to make those someday too 🙂

the sanding is faster with this but the ring has to be round, that is the only disadvantage I think, when I made my first wooden ring I also didn´t sand it with this method 😀 the second ring was much, much better 🙂

looks great! thank you for your input, how long did you sand the ring? quick way how to sand round rings can be seen in thes video: ring sanding

Hi,
Have you seen this topic: PET lamp? To me it seems like a good way to recycle pet bottles, but it’s purpose is mainly decorative, I guess you want some practical products right? This project: PET bottles uses PET bottles as a joining material, which is quite easy way how to use PET bottles.

Thanks for the detailed answerd I hope it will help someone else too 🙂 I will post my results soon I hope.. I really need a shredder first, tried manual shredding but it is so time consuming 😀

You still melt on a pan with outdoor cooker? How do you control temperature? Anyway the results looks great, have you done anything new this month?

Love it! you just cut the pet into stripes and then heated them to bond together? just watched the video on your site, I´m so glad somone is sharing their process.. I´ve seen some interesting stuff in precious plastic shop but I wasn´t able to find a description how they made it, it is sad right? taking open source information, experimenting with the materials and processes and then selling the final product without sharing how you did it… Did you made the metal fixture yourself? I´ve seen some cutters for pet bottles to make stripes but yours look neat!

This looks so good @timslab , in terms of output, I know that using a motor is much faster but how much plastic are you able to shred with this setup per hour? I know that it´s physicaly demanding to shred for a full hour but for a hobbyists who want the shredder as cheap as possible and doesn´t need to shred 100 kg of plastic every week this could be great solution right? Thanks for the answer

In the first post you wrote that you press the material with hammer during adding new plastic so I thought you could press it with the profiled board during the process not just during the final pressing. I didnt meant liquid like water but heat changes the viscosity of the plastic for sure.. If you press the two melted pieces of plastic together the form tight joint right? But what if one of the plastic is already cooled, will it bond together?

Thanks for answering so quickly 🙂 so the whole process of melting the plastic would take about 90 minutes in total? After reading the data sheet I think that it’s not so bad to do in your kitchen, but my mother would kill me if I ruined her oven with plastic smell 😀 yes the drawing is exactly what I thought, I dont know if it would work or the plastic is too liquid during melting that it wouldnt hold its shape between adding more plastic and compression.. I discovered preciousplastic recently so I didnt even started building any machines but I would like to try some recyclicg as soon as possible 🙂

It looks great! 🙂 three quick questions, how long did it take to melt the plastic? Did melting produce any horrible fumes? Would it be possible to use profiled wooden plank so that you would mold the final shape with every compression? Thanks for the answer
