Youtube cherries for makers
please post here your Youtube cherries and easter eggs
What to do with the V4 sheet press panels
A workspace building slingshots, HDPE ammo, and knock down targets is pretty much guaranteed financial success.
I found a low-cost version of a full automatic desktop injection machine. I guess this one is the one we go from (finally) : https://www.youtube.com/watch?v=M6UPpm4xlxw&fbclid=IwAR064vgVQB0CohrRsqRf8gXlIJd52rdsSVKyktqjgKR-tcdimL7IB7NBb84
from what i see :
– 2 Nema 34 steppers, around 200 Euro
– some metals, relative easy machined @ home for 100 – 200 Euro
– some electronics, around 100 – 200 Euro
– some links/belts, etc… around 100 – 200 Euro
Not sure we have to pre-heat hopper/feeder but lets see 🙂
Colin must be getting safety conscious, he tucked his tie in for the shredder test.
Nice ones, @s2019 – would drive me crazy this little stuff 🙂
the recent videos of all time DIY star ‘Marcin Jakubowski‘ became quite good – they had for long sound issues (and still) but perfectly forgettable when it comes to the details of the content. They had even Tom Lipton as guest.
Way to go – dear PP folks ; hopefully 3dprint is an allowed thing in the new ‘PP Universe’. @timberstar pointed to an interesting 3dprinter recently. If things go well – we may have the v3 or v4 extruder printing larger items next term; fingercross
New cool devices out there
pretty much a must subscribe channel; this one here is about the worlds best ever created machine, the lathe. in case you still don’t have one, please let me tell you, there is literally little to nothing you could do when it comes making plastic recycle machines. shredder, injection, extrusion and even molds to degree, all want you to have a LATHE 🙂
The first things I do to my students is letting them drill holes, from easy to difficult, after about 1-2 weeks full-time in the shop and only they fully sensed metal & forces as such, I send them for endless hours at the lathe for all sorts of different jobs and til now everybody started falling in love with this machine, and so will you.
Here’s a video of one of our best guys in the community, building a desktop injection molder, insane build but you get the idea.
here a good presentation by the creator of ‘opensource ecology’, interesting though pointing out how great projects are buried/sabotaged by personal/monetary issues, etc.. pretty much what i see happening to PP
not that i know of, i know there are hundreds thousands new and subsidized companies sitting on that stuff; i hope we can progress on the topic as soon the new lab is ready. by having huge space now, i hope we can have all sorts of new experiments (extending my other meter long and dusty of ‘project nr. 201212xxx’ shelfs, lol).
Yes, fun stuff.
Though you bring up an interesting question. We use shredding PET as a benchmark for the motors but is there anyone using (at the small scale) shredded PET for anything? Fortunately in our area there is a deposit on PET beverage bottles that helps keep them out of the trash but is there a good process for DYI recycling them? Your grind them to dust and 3D print approach has promise but is there anything else?
Very cool. I remember long ago visiting a company that was making 3mm diameter turbines with EDM. Very impressive. If this becomes hobby priced it will be a big deal.
not exactly plastic but this one left me speechless, ‘drill through anything‘
I wonder if the path from flakes to dust could be done by going back to the high speed circular saw blades of death. That concept tends to generate dust whether you want it of not. The trick may be to design a feed mechanism (belt?) that provides a steady flat stream.
@s2019 not exactly, as much I’d like; We teamed up with a 3D print specialist; they told me there are now plenty of companies here in Catalonia and elsewhere who shred PET but don’t know what to do with that stuff; hence 100Kg of PET flakes are about 10 Euro just. However, they found a way printing it but before you have to grind it down to dust. We put now all resources to work out a v3 (hard to do since it jams even at 3-4 Kw, not to mention it’s not made for hard stuff ) / v4 compatible grinder addon (transmission is the biggest problem right now). But lets see this soon in another dedicated topic. I am still struggling to get our new football field size hall up and running; surrounded by metal and plastic specialists; for now I know there will be the printer, shredder and grinder package, pre-grinded PET packs as well for whose who want to go straight to print 🙂
Doing this kinda instruments as in your rhysonic video is pretty much what I’d love to see coming out of the PP community <3 (thats why I love you alu folie mold ‘trick’, it seems to open endless ways to build real useful machines from lego like buildup plastic), way to go !
PPORG this machine looks insane !
I would like as well to build such a nice machine .
tor theos who have problems with wiring of heating bands here my video :
Yes, great video. Every summer I enjoy the inevitable stories where someone discovers that the giant inflatable swan is really a good sailboat and ends up several miles offshore…at least they are easy to spot.
@s2019 – yeah that’s a classic one 🙂 I would love to make that but the little shitters can’t focus on anything longer than a hour – there is so little you can teach them in a rather dangerous environment like a metal shop. It must be little like Tetris, frequent successes in a relative short time. But hey, you just found for the bigger boy – me – a nice weekend exercise (actually 5 weekends). Soon the HDPE ball business is booming 😉
here is a serious reason to get into blow molding 🙂
@timberstart – great stuff, thanks a lot.
Here a session with ‘Marcin Jakubowski’ from ‘Open Source Ecology’ speaking about building a Amazon store; interesting though for PPers because the fees & hassle seem to be relative reasonable. I hope we can get the first machines and components over there sometime next year 🙂
Well, if you have an extra half hour for classic metal working from scratch. The two Ford Hallam videos have been out a while but are eye candy I could use as a screen saver every day.
Of course you can use his techniques to make molds….who needs CNC.
@s2019, thanks a million – that guy definitely keeps me smiling & amazed for quite while (i actually have to remind myself to stop laughing – turning brass with a chisel). no seriously; that’s a great catch – looking at all the details – with a trained eye – there is endless tips and hints for PPers in those videos. I gonna watch them all now – get ready.
oh that’s neat – we were about to use old skis for the bow but PVC seems a little more easy since the boys can do that them-self, great find. thanks.
@occupypp , Thanks, now I need to find a cryocooler on ebay…great. I wonder if he could do as well just liquefying dry air instead of doing the N2 separation, not that much warmer.
@s2019 – yeah. I hadn’t much time but upgrading the shop & learning a bunch of new things. Here some motivation to get into chemistry – or better said metal alchemy in this very case. How’s it going ? You managed to sell the bench top mill to your wife ? I’ve got now a smaller one – BF20 – optimum – insane little beast and I am a little in heaven to re-design most of our production and machines with that. As for the neighbor kids, they’re eager to build a bow – there is much to shoot these days; from cops to flying plastic bags.
The upcoming ‘PP next-gen’ version aka ‘v4, just – plus more’ has a scheduler, adjustable via app – also for the shredder module. Luckily our cats want the ‘good’ stuff packaged in those plastic bags. It’s getting a little messy but from what I heard from the FDA ‘we eat plastic up to the amount of a credit card, a week’ – that should be fine with the cats too – sometimes we feel they’re trash bins – just on legs. But hey, you’re right – nowadays with soo many food scandals – you can perfectly use cats as bad food detector. We stopped buying a good bunch products of already 🙂
Then there is the v5 mixer module – perfect to smuggle some clay as worm treatment into the food. Perfect, I start loving this 🙂
Btw, I just checked on this bench top mill, it’s a widespread model and works like charm, for 3K just – quite a game changer but at second traders you get a mill which has gear cutting too 🙂
Yeah, unfortunately unless that feeder has a mechanical finger that can open a can of the good stuff, it has been judged inadequate in our house….cat eats better than I do.
Stefan’s workshop looks nothing like mine…hmmmm…
