Youtube cherries for makers
please post here your Youtube cherries and easter eggs
What to do with the V4 sheet press panels
hey all pp folks I have been collating anything that I think is of relevance to pp and have a playlist if anyone is interested.
Thanks, that will be useful.
For those that may want to know what is important on youtube….
It appears that an 8 year old promoting plastic toys was ahead of the save the world from plastic channels….Looks like there is some work to do
Gamers and toy reviews…How do you convince a kid to go learn engineering
A workspace building slingshots, HDPE ammo, and knock down targets is pretty much guaranteed financial success.
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?
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.
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 🙂
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
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.
@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.
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…
@ppme , since you have some great designs for combined pp machines, perhaps you could add one of these as an attachment.
Yes, the first few parts off of the machine would be some signs and plaques for the wife’s hobby….I know how this works.
The MPCNC design is intriguing and fits well into my interest in the build itself.
I’m still interested in exploring cheaper/softer materials for limited use custom molds.
Thanks, the TipBlitz is great. The CNC is too pretty for my garage.
I have been thinking of making one of the MPCNC routers.
Primitive Technologies, one of my top 5 favorite channels released a new video. Reminds me again of all the mental crap and ongoing cruelty and nonsense we accept, allow and even support widely isn’t actually any good for anything but reminding me what primitive apes we still are and probably be forever but also of replacing this stressful and exhausting engineering career – fake life, fake buddies, fake success, fake team, fake coffee, fake culture, fake ffs fake everything – with something more natural like machine building whilst helping others was possibly the best change in my life 😉 greets to project kamp 🙂
@s2019, funny you, if you get a <1kw motor shred all day long PET and whatever the kids drop in there whilst making sure it’s still running good in 5 years with your new shredder box, please send me that thing 🙂
you may have forgotten to take off your shades today mate, lol
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.
