Excuse my english.

After I found back to the sound of good old vinyl I had the problem every record aficionado has. How to clean the records properly!?
There are many ways around in the Internet. Cheaper ways like the Knosti or the Discofilm but also more expensive to unbelievable expensive ways like the formidable and excellent Double MatrixDouble Matrix from the german company ClearAudio, which also makes very nice turntables. Or the Cleaning-Vinyl-Records-Instructable by mattdp.

But there are always recurring mechanisms. On of them I tried to build on my own and as I can say, it works fine. I have had washed some of my records at a store near by me. They wash with a Loricraft PRC3 or PRC4 and I couldn't here a difference - neither better or worse.

Sadly I built this record-cleaning-device before I thought of making an instructable. So the thing is done, but I will try to give you as much detail as I can.

Please know that there are similar constructions around. This one is quick, cheap and dirty. I did it this way, so you can see that it is possible to construct this thing, even with two left hands. But sure you can improve, upgrade or just built in more accurate way.

The drive of my turntable was the broken part I had to replace. Unfortunately I only had a less powerful motor in the house and - yes, this is ridicolous but also works if you have only the opportunity to clean records - it turnes only counterclockwise. The weakness of the motor is the reason, why I have to push the the table sometimes in the video.

Be careful in every step and practice on old records first. I assume no liability.

What exactly do you mean by "... Seal the little hole with your weak hand and the big hole with your thigh ... " ?

First of all lots of thanks for your information on how to construct a machine like this one.

If you can, please answer only one thing to me:

When you say "nylon thread" are you talking about anything like fishing nylon thread ?

Does it (fishing thread) serves this pourpose as long as it is about 0.25mm diameter like loricraft one?

Lots of thnaks on advance,

Miguel Garcia

Direct drive turntables often burn out the electronics when you slow them down and they are trying to speed up. Get a belt drive.

why not simply use a cotton with a part of whater and alcohol?

This machine is based on the principles used by the 'Loricraft' cleaning system - this from their website explains why the thread is used......

The nylon nozzle tip of the vacuum arm does not touch the record. A fine filament nylon thread threads through the center of the arm and nozzle that allows the arm to lie very close the record. This un-calendared thread acts as a "ski" to support the arm and keep it a small fraction of an inch from the record. In fact, the distance is the thickness of the thread.

Pull a new piece of thread through each time you clean one side of a record to ensure clean thread rests on the record each time.

Hope that helps

Your machine looks like it works well, but what is the purpose of the thread? Do you insert the thread in all the record grooves?
I believe it is there to keep the nib off the record. The only thing touchng the vinyl is the thread.

Yes, that's right.

Great job on the record cleaning machine, but I don't quite understand what the thread is doing. Is it actually sucked through the tube while the record is being cleaned, or is it tied off and then you feed out some clean thread when you do the next record. If it's being sucked through, how much thread do you use for each record?

i'm not sure that cleaning in counterclockwise mode is ideal. You want to move with the grain and direction that the vinyl is going to play. Otherwise you are also "cleaning out" the surface tracks. think shaving.

This is very good project. I'll try to make one. Does string have to be fed through tonearm?
knarx (author)  JVC-Force6 years ago
Sorry for answering delay. No, it has not to be fed through the tonearm but in there it doesn't even harm...
Is the thread disposed of after cleaning? What is its purpose?
knarx (author)  syntaxinflux7 years ago
It keeps space between the vinyl and the Teflon sucking tip. Also it mechanically brushes dirt out. Parts of the thread are sucked in with dust and liquid. So yes, after cleaning the thread is disposed.

How would using Methylated Spirits work? Would it harm the vinyl (methylated spirits being 95% ethanol). It would take away from having to suck up the record cleaning liquid because it would evaporate.
knarx (author)  hcold7 years ago
Surely it will harm shellac but not the vinyl, even that every treatment with less alcohol would be better. I would not use it undiluted. First of all because the alcohol will evaporate but not the dust and not the dirt. So, without sucking it off the dirt you are willing to get rid off will stay on the record.

Nice! Looks like it works really good. Beautiful macros
