Time travelling 2 ½ years after this original post, you can choose to “cut to the chase” on page 34 where a summary of the method (at least, mine) and some comparative results in both sight and sound have been posted.

Still there’s a great deal of wealth and laughs to be found by plodding through it all from the beginning. Sometimes we learn just as well, if not better, from our mistakes and there are a few false starts and not too hot ideas within. But for the most part, there is a lot of clear thinking and experimentation that came into play. Thanks to all who have contributed.

After hearing the boys over in Europe chat this one up, I decided to give it a go. It’s a bit “fiddly” as they say over there and it does takes a bit of practice, but even my first attempt on a not-so-loved ancient and filthy specimen, produced a dramatic, near elimination of surface noise. Better than the proVPI clean that I’ve been paying $1.50 a pop to have done.
This is the “Before” shot AFTER I spent nearly two minutes cleaning it with my non-aggressive Audioquest brush. To prep the record for the wood glue, I used 4 small pieces of vinyl (First-aid) tape and placed them halfway into the run-in space of the record at the 4 compass points. This is to help peel back the dried glue film.
The premise in all this is that plastic vinyl is very resistant to glue adhesion. Wood glue being predominantly made up of polyvinyl acrylate and is a close cousin to polyvinyl chloride (LPs) so they get on well together without any plasticising transfers – at least, for the short run. When they do come apart, gobs of junk caught in the grooves throughout the ages lifts off with the glue.
This was my first attempt. A little too much – probably about 40-45 grams of glue when 30 grams probably would have done the job. Too little – and it’ll be the devil trying to get it off in big pieces – the ideal being to get the film to peel back in one big piece. Too much – you risk having trapped pockets of undried glue. I used an old credit card to spread the glue on an old churning Rek-O-Kut. If you make it just a bit thicker toward the lip, this will help to give purchase for lift off. Normally this should take about 4-5 hours to dry (1/2 hour after it becomes transparent). Mine took about 8 hours.
Not one piece, but about four – not too bad though. I’ll try some tape on the run-out space next time.
Through this “death mask” impression, the grooves modulations are easy to see. While there is some dirt pictured here, a lot of the big stuff is small imperfections on the vinyl that were magnified by bubbling as the glue dried.
Seeing, is not always believing. But hearing is. Snap, Crackle and Pop have left the building.
