Seems most people make styrofoam shredders with screws, drywall screws I think. I was wondering how that compares to using nails instead. Looks like your nails don't have heads? What size and type of nail? What exactly are they nailed into? What keeps them from coming loose, flying out? I guess that would surely be one benefit to using screws instead. I wish for my pieces to come out roughly 1/8" dia or so. What size do your chips come out? What is your nail spacing?
All good questions, most of which I can only give guess 's to, as this was a long time ago and I've since given the setup to a friend. The nails were small perhaps 3mm and appointments 15mm long, there were pushed through a hole in a pvc tube. An other tube with a slot cut down the middle was inserted to stop the nails backing out . I believe the rows were spaced approx 1cm apart offset ( at the speed it ran the spacing wasn't too important. The result was bean bag use able size. Hope this helps.
i really like the ideasince i was already looking for a way to grind up th styrofoam, is the resulting stuff also usable for a beanbag chair? if you could make a photo or something of it would be really great
Great mate!! How did you attach the nails to the PVC pipe, and what size are the nails? I've retired from Oz and am now living in the Philippines. Building here is done with 'hollow blocks' - cement blocks that you have to pick up with two hands, because they're so weak that you'll just break off a corner if you try to pick it up one handed!!! I want to make solid styro-cement blocks instead, but buying polystyrene beads here is unbelievably expensive. This looks PERFECT!!!
Sorry about the V late reply, the nails are about 20-30mmx2mm . I predrilled and pushed the nails through the pipe and then slit another pipe down the middle and inserted it inside the first pipe. Cheers
@@daza2838 You can use blades like a common shredder, like the ones used to shred other types of plastics. I'm asking because I think is very interesting the way you shred this type of plastic, that is such a problem when shredding it, because of it low weigh and sometimes it melts in the blades because of the rubbing (it already happened to me :( ) I'm interested to know more about your styrofoam shredder if its no problem to you! we can share some tips and tricks of this special material, i've been working with it during this year. Thank you for your answer. Regards
@@carolinaaliciaespinozajime5960 I never had the problem of the material melting and the nails stayed sharp as the material isn't hard at all. The result was small balls of material which was much easier to store and perfect for my use.
@@daza2838 I can understand that, that's why i feel that's really interesting what you did, and i would love to know more about it. I'm searching ways to made as efficient as possible de recycling process of EPS
Хорошая работа. Спасибо за видео. Удачии

Genius idea thanks, as the shredding machine is quite an expense. Thanks bro

I should think the shredded foam would make excellent bean bag filler, I was thinking about using it for that myself :-)
Yes, the results would work perfectly with a bean bag, I'll try to get some pictures.
Cheers

Is there anyway to get complete build instructions?
Sorry about late reply, I don't have any build plans, but it was a simple process. If you still need tips give me a buzz.
Hi what's that you use to connect the flywheel to board?
Sorry about the late reply, the flywheel is attached to the shaft after filing down the the shaft to fit the slots in the Flywheel.
@@daza2838 thank you for your response, appreciate it, the Lord bless you richly
why did you decide to use nails instead of blades?? regards!
The nails shredded the styropor into small balls, perfect for my application.
Not sure how I would've incorporated blades....?
Cheers.

but locally and with home made machines, you know precious plastic?
