Our DIY Ultrasonic Record Cleaner

Recommended Posts

@Owen Y I received the motor of the rotisserie I mounted it on the kit and perfect! The only problem is that the direction of rotation is the opposite to the indication that you put on the iron plate, does it create problems? I can't mount it any other way!

Turn the motor on then if it is not running the correct way, turn it of then on again. 50 % chances it change direction. If not at the first try, a nother try and you may get lucky.

@georgesgiralt But it is not possible to doll the direction of rotation of the motor, even turning it off and back on, maybe it should be at 12V and reversing the power cables, maybe you would change the direction of rotation, maybe, but it's not my case.
My question was whether the sense of rotation (I have the counter-clockwise direction at this moment) is problematic for optimal disk cleaning?
Thank you

Did you get this motor https://www.kogan.com/au/buy/gasmate-240v-rotisserie-motor/  @maxpina ?

 

If you turn it off, wait a bit, then turn it back on it should change direction.

 

The problem with the anti-clockwise direction is that the spindle tends to drift out of the motor shaft.

Se lo spegni, aspetta un po ', quindi riaccenderlo dovrebbe cambiare direzione.

 

Il problema con la direzione antioraria è che il mandrino tende ad allontanarsi dall'albero motore.

I took this, hopefully https://www.ebay.it/itm/Electric-BBQ-Roast-Rotisserie-Grill-Motor-Rotator-Barbecue-Tool-220V-Black/153289597732?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 now I'll try to do what you tell me.

Different motors to the kogan one in my link may not change direction.

Hello

I've trouble finding Hepastat 256 in Europe. It seems it contains some chemical which is banned here. (or the maker do not care certifying it's product in Europe..)

So I was told to use one of these instead : Selgiene  or Cetrimide  (the latter being invented by ICI could well be availlable in Europe 😉  )

They are quat devised to clean lab material but the Cetrimide  is said to be inefficient in presence of blood or microbial products ...

I still have to find a supplier willing to sell a liter to an individual and not asking one of my kidneys for packing and postage...

I have been using my machine regularly, with triton-x, isopropyl alcohol and water (just tap water, which has worked well to date). The essential add on after a quick spin rinse in a tub of water is the drying rack.

Very cool, Justin.  :thumb:

 

But whilst I can appreciate that 'just tap water' has worked well so far ... perhaps you need to do an experiment and use distilled water for one cleaning - and rinse - cycle?  Just to see if the LPs cleaned this way have a lower noise level!  :)

I really mean to do that, but have not got around to getting distilled water to do that to date, and figure that any water is better than the vegemite smears and other detritus you sometimes come across on old records! Any suggestions for good sources for bulk distilled water ?

 

cheers and thanks

I buy 5l containers of distilled water from Autobarn.  Maybe $13 a pop?

@Juzbear Could you suggest which part mixture you use in the various ingredients for cleaning in the ultrasonic bath?
Thank you

I would defer to greater authorities, and aim to use distilled water as an ideal. Nonetheless, my current mix is 10ml of triton X100, 150ml isopropyl alcohol, made up with water to the appropriate level. (My ultrasound machine is the standard size for this thread, fitting three LPs.)

 

I usually heat the water to 40 degrees. I am sure many would disagree, though having looked at cleaning threads and also threads on flattening warped records, 40 degrees seems well within the zone where you can leave a warped record in a flattener for hours and it will not flatten. Hence I figure it is unlikely to damage the record, and to date I have not seen any issues.

I use 50ml of 10% triton (so therefore 5ml triton raw)
250mL of Isopropyl (results in an overall 5% concentration)
4.7L Reverse Osmosis deionised water

I change the subject, that is we admit to having done the cleaning and that I can't perceive the difference, there is some system with some tests with an audio editing program (Audacity?) To measure the success of the ultrasonic cleaning process, of course we should surely already hearing by ear, do any of you have any experience? Did you do any tests before and after cleaning, objective tests with measurements?
Thank you

How can u quantify a subjective test of “does it sound better” also it varies record to record, how dirty it was etc. but I do typically notice an improvement in quiet passages, less crackles and better dynamics

I don’t know that I have perceived an improvement in sound in an otherwise pristine record (ok, I haven’t), but for purchasers of second hand records and for new records which have pops and crackles, which are often particulate matter (ie. bit of stuff), it clearly does what it says on the tin and cleans the record. I don’t know that there is any great consensus of opinion that ultrasound cleaning improves the sound in anyway other than removing stuff that is getting in between the wax and the needle.

It's come to our attention that the records can contact the ends of the SS tank if the end clearance is too small & if the SS kit frame is not a TIGHT immovable fit to the tanks sides.

 

If the SS kit frame moves with vibration, the records can contact the end of the tank & stop rotating. 

In such incidences, the rotating motor can drive the spindle out of the motor.

 

So, we recommend :

 

1) Checking that you have tight-fitting top frames - if not, gently bend the flanges inward (eg. on the floor, with a block of wood). to get a tighter fit.

 

2) For good measure, lift both the motor plate & the opposite bearing plate, upward (as shown below) so that the records sit a little higher - raise fluid level a few mm if you feel necessary.

Hi @maxpina - excellent video, thanks!

 

The filtration stage is important I thnk.

I have an aquarium-type filter-pump system,  but I have not been using it constantly or in the same way as you do - I like your system of connecting to the bottom outlet of the tank. Is the fluid circulating OUT from the bottom & returning IN to the top, of the tank?

 

And what is the function of the addition rectangular box between the tank outlet & the filter pump?

 

Thanks for the inspiration!

 

PS. May we post a link to your video on my DarkLantern blog page and/or on our local DarkLantern NZ forum?

 

Cheers, Owen

Ive done the same as Max, And i think i can chime in.

 

He's put a circulation pump in a jiffy box, the canister behind the US tank has no pump, just takes a water filter cartridge like what you get from a water store.

 

Ive done something similar, using a cheap pump, and a 0.5 micron sediment filter. The Results are excellent :)

Thanks @benny - if you don't mind, would you post some details of your set-up?

Component parts, etc.

 

I have an external filter with pump unit, ~400L/Hr.

      So what are folks experience with Affordable ultrasonic record cleaning machines of the non DIY variety ...

      Item: Okki Nokki MKI  MKII RCM (White)
      Location: Blue Mountains, Sydney
      Price: $520
      Item Condition: Excellent
      Reason for selling: NLR
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
       
      EDIT: This is a MKII and not a MK1, as I first thought. This means it is manufactured in China (not Germany) and has a plastic instead of metal wand. Apologies for any confusion caused !
       
      For sale is a MK II Okki Nokki record cleaner, purchased in 2014 from Krispy Audio. Included in the sale are wands for 12” and 7” records, a clamp, and dust cover. The cover and 7” wand are additional purchases and retail for $115 and $75 respectively, and the 7" wand is unused. The dust cover is a must IMO, as keeping dust from a RCM is pretty important !
       
      The unit has seen mild to moderate use, and there are months where it’s barely used. 
       
      For anyone not familiar with the Okki Nokki, it is a wet - vacuum cleaning system, and works by first agitating debris from the record as it rotates via a brush placed along the grooves. After a few rotations (the unit has forward and reverse) the wand vacuums the liquid away, leaving you with a clean and hopefully crackle and pop - free record. It can’t perform miracles and fix a record retrieved from a dumpster, but for gunk, mould, fingerprints etc... it does a good job.  And with the debris and detritus new records come with, it’s a good idea to clean everything, not just 2nd hand purchases. Your needle will thank you. 
       
      A few months after I received the unit, it had an issue with the vacuum cleaner which was easily fixed by a fuse replacement and was a common problem with this model. It has been trouble - free ever since. 
       
      The original brush is long gone, so you’ll need to grab something suitable. There are plenty of options, and of course you’ll need to arm yourself with a record cleaning concoction. 
      I’ll also throw in a back - up set of spare velvet strips, which attach to the 12” wand and should be changed about every 50 records. 
       
      Shipping is possible as I have the box for the unit, however I don’t have one for the dust cover and so preference is given to local pick-up.

      Item: RCM Sensor 2 Phono stage + Kuzma Stabi-S Turntable (with PS2 speed controller) + Stogi-S Tonearm + Lyra Delos Cart
      Location: Mount Martha VIC, 3934
      Price:
      RCM SENSOR 2 = $3800  - SOLD (TT still available)
      KUZMA STABI-S TT + STOGI-S tonearm + PS2 Upgraded Power supply + LYRA DELOS MC Cartridge = $6750
      (comes with free perspex dust cover, as per photos)
      Package Deal: $10K (RRP for this setup is approx 15K. Please note I prefer to sell this whole package COMPLETE)
      Item Condition: 9.5/10
      Reason for selling: Have purchased a new car and need funds for that.
      Payment Method: Cash on Pickup or Bank Deposit. Paypal is my last preference and you will need to pay an extra 3%.
      Preference given to local pickup VIC buyers.
      I can send interstate at buyers expense, but very much prefer not to because of risk of damage.
      Extra Info: I bought these last year from Sonic Purity in May 2018, so this gear is approx 1 year old.
      The sale is somewhat regrettable, however I have other priorities now.
      The RCM Sensor 2 phono stage is magic and extracts every detail from the Cartridge while giving strong bass.
      (Has Furutech Connections, and external latest power supply)
      There are many reviews online about the phono stage and many who have heard it will confirm its high reputation.
      It has a multitude of loading and gain options.
      https://sonicpurity.com.au/store/phono-stages/rcm-sensor-2
      The Kuzma Turntable is equally amazing in sound and build quality.
      Latest 2018 30mm thick platter!
      https://sonicpurity.com.au/store/turntables/kuzma-stabi-s
      It has the upgraded power supply which means you don't need to change pulleys etc to change the speed.
      The speed controller has a digital display.
      It comes with Stogi-S tonearm, and LYRA DELOS cartridge. (has had little use, but is run in. I honestly don't know the hours)
      Those who know this cartridge can tell you that its super detailed in the high frequencies and still has gorgeous midrange and strong bass.
      Cartridge azimuth has been painstakingly set up by Rom at Sonic purity, using computer software.
      I look after my equipment with a lot of care and live in a smoke free / pet free home.
      Auditions are welcome at my home only for SERIOUS BUYERS.
      Upon sale I always make donations to SNA.
      Thanks for watching.
      Cheers,
      Paul.
      Happy Easter to all.
