@ewanenj
hi ,
my shredder is the Titan
I got mine for 20£ as it was second hand,
works fine,
thickest I’ve put in is about 2mm ,
the design of the teeth is what causes issues
as it clogs due to the cutting action,  however I never got around to sanding and polishing the blades , which will help ,

the RPM is around 80. I think  which is alittle faster than daves

youl need to consider couplings sizes, anything above L110 but different borehole size, as on the gearbox the shank is 35mm where as the shredder is 20mn

@javierrivera

another idea to add to the mix ..

getting the slightly thinner 7ft wide containers with the higher 9ft height to fit snug on a lorry tailer which stays on the trailer…

the transport would mean using local lorry drivers from each place to deliver it to each destination?

or just covert a trailer itself, they can be just as secure, and you can have quite a massive space… with removable sides?

@berkasal

yes the motor/planet gearbox/electronics all come from the commercial product
‘garden Mulcher”

its quick compact due to it being inline planetary, much the same as a cordless Drill..

thanks

maybe it starts out in a semi-permanent place ,like a dockside harbour/dry mooring… (or would need to acquired land somehow)

then when it gathers more interest and success, more people will be involved, more potential to move or have other setups…

if a council gave us 1000 square feet of land, which isn’t much of an ask TBH,
that would create potential for a starting point…

im definitely in, ive been needing to start something like this for some time, just im not really entrepreneur but il do what i can to help, shipping containers are the future, !!!
just need a community and we are away !

my skills and contribution,

i work as a technician in an art gallery at the moment, get two days off a week, so not all that bad for time to help with this.

im am also an art graduate, and was sculptor assistant, so i can do things like welding, and polish stainless steel if needed, designing etc,
plus carpentry/joinery by trade. plus lots of other things/ the list goes on…

ive already made a shredder, and trying to make the extruder… ive got tools for making the machines, and also ive got a wood lathe,
and also potential contacts for stuff like metal supply at a discount,
and i know a reliable lazer cutting service in Lancaster…
and also i know someone who can lathe metal parts super nicely..
😛

in terms of the other idea , of a mobile buss.. its not uncommon,., i used to help my uncle with his (Stock car racing) formal 2.. and i would see the formula 1s would usually convert a Coach from the scrap yard in to a 2 level car transporter + workshop + camper van style living,,, probs a lot of money but it wasn’t like formula 1 you see on tv, so a lot of it was just fancy looking junk..

ive made a very frankenstein prototype, just to test the power,
had a go at clamping the large wheel with my hands+gloves … couldn’t stop it turning, so i know it’s got some torque..

i suppose it will be good until i damage the motor controls, then id have to find another treadmill….

@tinch

its a good question , i think it needs examplafying to make it easier to understand how gearing and torque work with RPMs and horse power, somehow..

but in essence yes , gearing it down massively would work bit, however really slow speed means it will take longer to process plastic then cutting it with scissors…
don’t know if you have ever come across an art work by Arthur Ganson, called “machine with concrete” its geared down so much that the output will take a trillion years to do ONE rotation, i bet it has silly amounts of potential torque though…haha

@andyn
ahh thank you for the info

yeh this one isn’t fancy enough for that, i tried it all disassembled from its original form a few times just messing around and it goes without any error, even when have basically bypassed the motor that would control the slope of the treadmill, and it still goes, haha

this one rums on 230/40v i believe, as i cant see any transformation on the circuit, just takes the mains to DC, hopefully it will work in the end

hi @heyeco

for this id recommend injecting it with the extrusion machine,
you can make it out of 1inch box section in the pitchfork shape you want. and cut an entire face off, then weld
angle on to it all around the edge to create a surface that will allow a bolt on plate to fully enclose the injection mould. and then a make screw on nipple for it to fit on to the extrusion machine, ?

@andyn its only jammed a few times when i put 3 milk cartons together, which is kinda unnecessary,
or when i tried a thick Polypropylene jerry can pieces, which are about 4mm thick on the some parts,

the jaws have the original grub screws tightened agains a flat on the shaft, the bolts are just to keep them tight because they kept loosening, as i didn’t want to use lock tight glue,

Owner: kettlekekkers
Motor type: mono-phase
Voltage: 230/40v AC
RPM: about 2500
Power: 2.8kw
Reducer: inline planetary/comes with motor
Output RPM:45’ish
output Nu; 500’ish
Result: Success. very good

Details: cheap and easy to use and apply to assembly.
shreds up to 3mm thick PP or HDPE as far as I’ve tested, compressed milk cartons could be considered more like 5/6mm thick.
electronics easy to understand and reassemble
when clogging occurs, its easy to revers with the already provided switch.
,
..
disadvantages’ : its very loud! and has a 36.5mm shaft output , no choice.

My shredder and its costs

@waddy37 hi, yes my shredder is still very good, i only shredder milk bottles though,

I’ve not even welded the box together and its doing fine hahaha,
would have to try and get a few quotes from different laser cutters, businesses in the midwest England tends to be cheaper in my experience,

@henners

hi , if you mean the barrel tooth , then mine just slid off after opening the front plate, which basically centres the axle, some might have a C or E clip holding it on, in which case you’l need to fight it, or buy the special pliers for C/E clips

@trent-robertson that is correct, i used the motor/gearbox/and electronics
i coupled it with a pair of jaws to compensate any misalignment.

@xxxolivierxxx thankyou! yes it does look a monster.

hi @timslab

yep , mostly milk jugs

hydraulics is the way to go,

yeh i can see you’ve got some MDF in there, i would just go with some 8mm steel plate, for reliability

even this shop press does’t do the best job, as the heat is taken away when i transfer it for pressing,

@timslab
hey , ive been using this clothes press to create sheets of plastics
i use a 12tone shop press also between two plates of steel to finish off the plastic so it stays flat,

the shredded plastic is placed between like a nylon bbq liner, or re-usable baking sheet first, then heated from the top in this clothes press, when its melted, i transfer it to the shop press,

< those ore ok for specific plastics and products for a certain amount of time, but the blades wont stay sharp for long, as plastic is more dense and consistent than wood twigs, you might as well put it through a lawn mower,

(DON”T though… haha ) !!!

but i suppose if you want to go even cheaper, and do no mechanical engineering it will suffice

@jsk555 you could take a fair bit off, just be sure its the absolute right thing to do, and not any other potential reason its not lining up

my laser cutting service made a mess of the parts i ordered, i fixed the issues by belt sanding all the faces and sides a small amount,
dave does this in the video, you might need to take more off the faces if your box isn’t fitting snug,
0.2mm of sanding in each blade will equate to approximately 5.0mm tighter after doing all faces as there is a lot of parts. ?

@timslab thanks, yeh i might end up doing that, as they dont cost much,
the gears are all metal, needs to be with the power output

@jsk555 hi, have you got some photos of the issue, which blades are you talking about, do you mean that the axle blades are getting caught on the stationary opposing blades?

if so , what you need to do is grind the spacers down a small amount, or all of the surfaces where the lazier cutter will have created a rough surface.

i got my counter sunk bolts from ebay, mine where just M10 though, so a little loose on the frame, but shouldn’t matter when you tighten it, as the washers for the axle line it up anyway.. .

hey, great video!!!, id love a work shop like that to experiment.

might i suggest some ideas that you could experiment with as ive wanted to try human power as an option, but i don’t have the machinery to always make what i want,

i like the weighted fly wheel, i think thats a must, the heavier the better when in motion,
the chain and sprocket system sounds good if you reduce it massively, which would likely require several axles mounted on bearings to transfer the power, fair play if you have the means to do so,

what ive wanted to do is use the Planetary gearbox from my garden mulcher in the same context, with a heavy fly wheel and a strong bicycle to transfer the power.

hi @ashrak sorry for the late reply, i don’t get notifications unless tagged unfortunately 😛

that type of shredder generally doesn’t have a gearing system, so it relies on the motors speed and fly wheel with sharp blades keep up momentum, so it will lack Nm of torque when applied to the low speed shredding requirements

tooth Barrel style garden mulchers are high Watts and double planetary geared down like a cordless drill , so they have hight torque levels.

I’ve the same problems and interest, i guess to some degree most plastics will erode into smaller pieces of plastic eventually under water, and if it is really shallow, UV rays might eventually degrade it,? especially if there were no stabilisers in the plastic,

ps. is the artist Jason deCaires Taylor by any chance ?
