A winch sounds great, slow as fuck but powerful. I was also thinking about experimenting with a roller shutter door motor, you can find them on aliexpress for less than $150 and these things can lift 600kg. This one for instance has an output torque of over 400n.m which is plenty for the Shredder
No need to add more fuel to the argument buddy. The design is yours, you don’t have to share it with anyone, period. If anyone wants to force you to share your designs, just tell them to F*** themselves.
If anyone wants to take the original PP shredder design, build a shredder, paint it Pink and sell it as a “Premium Shredder” for $20.000, go for it.
If anyone wants to modify the original PP designs and keep the modified designs for themselves, who cares.
If anyone wants to make a clothes pin mould and they don’t want to share the designs because they are looking to make profit out of it, and then someone reverse-engineer the mould and shares it with everyone? Sorry, you should have waited for the patent to be fully approved before showing everyone your product, now deal with with
The point is, people should stop complicating themselves about this open source crap. Precious Plastic was given to the world for free and people can do whatever they want with it. The only thing you should not do is selling the original PP designs, but someone has to be really dumb to buy something that is available for free.
By the way, don’t worry about Dave, he’s well fed and can afford his weekly dose of chocolate. Royalties, tips, and any other fees given to the project are optional, no one HAS to give money to PP if they don’t want to, because the project was never intended to be a money-making thing.
The most common option for this type of moulds, is to use heat resistant silicone or Epoxy, waaaaaaaay better than plaster.
I can’t find the topic, but here’s the Idea.
Yes, plaster of paris will work, but if you want your mould to last it would be better to have a hollow steel mould like a shell and put the plaster mould inside, that way the steel mould will help absorbing some of the pressure and make your plaster mould last longer.
The Precious Plastic Mexico guys tried this some time ago and worked pretty well.
@msnmsk seems like they changed the link or ran out of stock for that item. Here’s an alternative https://www.onlinemetals.com/en/search/results?q=stainless+steel+sheet+0.125%22%3Arelevance%3AMaterial%3AStainless%3AShape%3ASheet&checkbox=on#
Welcome to precious plastic @atkvina1
Buenísima idea 😉
@msnmck all these shredder versions are the same thing, the only difference is that the newest version has a square hopper instead of a piramidal one, and an easier to remove mesh filter. The base of the shredder box is the same in 2.0/2.1/3.0 so you can use these files without any fear
I could figure out something as well, if I had access to such data
Good luck with your shredder @chicks
Your gearbox has a pretty good reduction factor, and that motor should give you around 395.59 n.m of torque which is spot on for the shredder. Just make sure your gearbox is good enough for a 2hp motor, there are some gearboxes with lots of reduction but they are made for garage doors and other low torque applications so they only support ~0.5hp motors
If you haven’t purchased your couplings yet, I recommend Martin roller sprocket couplings, they are amazing and super cheap, I paid around $27 for 2 sprockets plus the double chain. They do allow for some misaligment as well thanks to the chain https://www.amazon.com/Martin-Roller-Sprocket-Hardened-Bored/dp/B004JXWHU0/ref=sr_1_1?ie=UTF8&qid=1528433529&sr=8-1&keywords=martin+sprocket
Thanks both, account deleted. Friggin spammers, hope they burn in hell….
