Industrial Bubblebag Alternative ........

[foomar]

Have been useing a selection of industrial sieves for many years for hashmakeing , equally good wet or dry and with some advantages.

Durable in use and can be easily repaired if damaged , brass or stainless construction to a high standard.

If used wet can be dried in minutes with no bags to mould.

Do the work in a bucket and pour through these , should last forever.

New price runs into 100,s due to the standards to be met and garantee of accuracy as each one has a certificate and serial number , very cheap from Ebay and boot fairs ect , non metric worth little in industry nowadays.

This selection covers 15 - 250 micron and cost less than thirty pounds in total , double up as bud driers and larger apertures are handy for compost.

Very nice screen set you have there.

Can you show us photos of all your screen sizes?

Yes those are very costly how much do you have invested in your screen stack?

Very nice looking set. I have priced these in the past for some scientific research I was doing and they are quite expensive. I have seen them at swap meets though for cheap though they were a bit harshly used so I didn't pick them up. Never thought about using them for this purpose. Did you pick all of those up in one purchase or have you picked them up periodically? How much have you spent?

I used to use some just like that, except I was using them for soil testing in a lab. They are very high quality and should last a lifetime, or at least the ones I was using.

These and 20 ish larger mesh sizes were picked up over several years as they were found from various sources.

Skip at a factory that made carbide inserts.
University geology dept,
Polished up as brass ornaments at boot fairs.
Couple off Ebay for next to nothing.
Forensic lab that went metric.
Potter who made his own glazes.

They are quite widely found in industry , older ones have little value as they are marked in thousands of an inch and original certificates are lost or invalid under ISO standards.

Any slight damage or tear in the mesh is easy to fix with solder or glue as they are steel or brass wire rather than fabric , stand up well to vigorous carding at low micron sizes.

Several names on the market , best are by Endecotts but there were similar firms in the USA , standard sizes for diameter so all makes will stack watertight regardless of age and origin includeing currently made metric.

Laser cut have circular appertures and possibly the best for our needs in the 10 - 25 micron range but are incredibly expensive and few second user yet.

Modern made sets from India are cheap but the quality is apalling and mesh sizes are wildly innacurate so best avoided even for hash.
Have seen no chinese made yet but they would probably do the job if available.

Given such a choice it might seem a bit odd that the only one i ever use for dry sift now is a 250 micron , product suits my tastes but the system will produce as pure as bubblebags if you want it that way and use several sieves individually or stacked.

Sounds very coarse but suited this MIS well and kept the full character.





There are machines to vibrate stacks for soil analysis but an hour on top of the tumble drier does as well.

Happy to lend them out as they will not be damaged , would not risk bubblebags with my clumsy mates.

I should be a salesman for Endecotts reading this back but it really seems an ideal solution avoiding the weaknesses of bag systems.

Some were free but none cost more than a few pounds , those in the pic would cost 3000 for the equivalent new , happy hunting !

Nice selection of testing sieves Foomar!!! I've been collected some testing sieves here and there off ebay, some excellent bargains. A set of 2-3 used testing sieves of No. 80-170 are perfect to make some great dry sift hash and should outlast any mono-filament mesh or bags. I've never tried them wet, but maybe a test run in the future.

Experimenting with hash making is a blast and addictive. Currently I have 8 bag set of Bubble Bags, 4 testing sieves, silk screen & Drake arbor press.

The Drake model 1 3/4 arbor press was a garbage day find from a few house down the street. 3 tons of force make some great pressed hash, plus it's a cool tool...



Some arbor pressed hash, mixture of dry sift & bubble, got a little crazy pressing this one, but the end product is excellent!

Hi Seneca

Good to see someone else spotted their potential , they work very well wet and save carding , find dry process below 100 micron smears too many trichs and only doable wet.

If you try them wet i reckon you will not want to go back to useing bags.

With aperture matched to trichome size it is easy to produce a tiny amount of almost pure material that looks like a line of coke , vibration enougth to make the mesh jump the bone dry material for an hour or two works perfect , sounds silly but a cheap vibrating sex toy is ideal or rig a motor with an eccentric cam.



From my forthcomeing best seller , 101 Things to do with a Stoner Sieve .......

(2) Seperate pollen from flower debris , pure pollen through a 20 micron.

(3) Grade seeds by size , choose a mesh which allows the smallest and most spheroidal 10% to pass and be discarded.

(4) Sprinkle flour or sugar in cooking /bakeing , survived a dishwasher and looks like new.

(5) Filter out bits of fish and chips from hot old cooking oil prior to putting it in mrs Foomars car with disastrous results.

Those are very nice sieve's indeed.> A little bigger and they would be seriously rocking. ( i love big batches )

Kind of reminds me of the aquabob... a pvc version of that.. with screens glued to the botton ( or metal inserted if you buy stainless)

Rob clarke mentions them in his book Hashish.... simple to add more as they screw into each other... you can stack em up high ... use em dry or wet.. attach a vibrator...

Very cool idea for sure...

Thanks for sharing your hash and your system.

peace
Bubble man

Ive had these for years, I have the whole set. It's actually made for sifting soil, the biggest screen catches fist size rocks..


It works so well!!!



But honestly, I should finally buy me a Bubblebag set...

Prices new have gone up a lot over the years , probably too high now for personal use.

The Endecotts website contains a bewildering choice of suitable products and worth a look and a catalogue download.
Some interesting machines , sonic sifter for one and sieves down to 5 micron.

Then check out the prices here and faint , my collection would be over 10k to replace with equivalent new.

Nice test sieve set. I've been slowly trying to build mine back up but decent ones seem to be hard to come by lately. It's one of those, be there at the right time kinda things especially with ebay. For anyone looking to buy some, be sure to check the micron size. Many are numbered like #40, #50, #80 etc.

 

[Ed Borg]

Thanks for all the shared information. I have seen a few sets over the years here in Amsterdam, however they were of cheap quality. Typical knock-offs as this industry seems to have many. Hopefully Delta-9 Labs can share something better with you one day! Success to All.

Hi Seneca
If you try them wet i reckon you will not want to go back to using bags.

A couple of questions about working the sieves wet.

Do you let the material and sieves dry before collecting? Do you re-shift/dry for collection?

This is how I envision your wet sieve process.
1. Mix the bud & trim with ice in a bucket
2. Stack your sieves and filter out the mix
3. Allow the sieves & trichomes to dry-out completely
4. Re-shift dry to collect each grade

The sex toy is a fantastic idea to vibrate the sieves, I can think of great names for that technique!!! Any specific vibe settings work better at have your ladies drop their trichomes

Last wet run went like this,

Bone dry material from the freezer , previously broken up to pass a 2 mm sieve to remove twiggy bits and seeds.

Mix agressively and fast with smashed ice in bucket , electric cement mixer in this case due to volume and pass through 250 micron sieve.

Allow to settle , decant and discard water , use slurry as feedstock for a stack based on mean trichome size and desired purity , if you have a microscope and a choice in the 10 - 25 micron range.

This batch was well mixed so just went through 10 - 125 - 200 for a good 5% yield , particles between 10 - 125 is a good clean smoke and contains enougth plant material and all the trichs to give the full taste.

Flush hash to the side of the tilted sieve off the mesh surface and remove whilst still moist for drying or further processing.

Two minute clean up and no mouldy bags to worry about.

The 10 micron sieve made a large improvement in the quality of smoke , takes out the spikey hairs and dusty shite from outdoor and worth finding one or something near it.

eehhhhh... i think these might be better applied as dry sieves. seem somewhat small for processing ice water extracted resins compared to a bag system (they only mold if you let them.. ya know...). Don't get me wrong, they seem useful, but not for ice water extraction as you couldn't run more than a gallon at a time, I would think.

These are eight inch diameter and two inches deep , ran 12 litres of slurry and finished in four hours processing three growers collected trim from the last six months.

The mixer was still brand new and used more for a laugth , electric whisk and homebrew buckets serve normally but less fun.

This was nearly three kilos of dry sugar trim so should be plenty big enougth for most growers needs , difficult to dry sieve much below 100 micron without carding or overnight mechanical vibration in a fridge , trichomes are to fragile to allow this with any force and better done wet.
