Cleanup and restore of a Columbia Viva-Tonal Grafonola 128a
Posted: Thu Aug 13, 2020 11:15 am
Hey all! I recently had this upright drop into my lap (very local, not a bad price (paid £147), and all original bits it seems) and managed to snaffle it and get it home in the back of the mini. I did a complete dismantle, cleanup, and obligatory making of soothing noises while stroking, and I took pictures as I went along to share what I did so that the learned minds on here can take a look and offer hints and tips on anything I might of done incorrectly, or in general to help me or others on the forum polish up our techniques at erm... well polishing up amongst other things!
When I got hands on the beast it was dusty throughout, many scratches and scuffs (the top of the lid has so much veneer gone I’ve just found some needlework to sit on it until I can sort that bit. Firstly I removed the two strips holding the grill in place and removed it for cleaning I gently brushed the loose dust from the cloth with a camel hair artists brush then gently separated it from the frame, and set it to soak in warm water with a couple of drops of simple soap. After a good while a lot had soaked out as the pic shows lol I after also unscrewing and lifting out the motor, it gave a look at this models internal horn too (which I took out, cleaned, and replaced a little later) On to cleaning the motor - it was actually running surprisingly smoothly despite having not seen the light of day seemingly for decades - the state of the motor plate gives an example of how long - that’s some premium collected grot on there!! The motor is nothing special, a two spring Columbia 100 so I won’t cover the stuff that is doubtless covered elsewhere on the forum concerning motor service. Suffice to say I greased what requires greasing etc etc and it cheerfully starts from three crank turns from dead flat. Back to the grille cloth! Now cleaner, I dried with a gentle hairdryer, and re-glued it to the frame with great care and a lot of pegs to let it dry entirely. I rebuilt the reproducer, (again a topic covered in depth elsewhere here much better than I could so I won’t go into that,) and then polished the ever-loving-crap out of all the metal parts. I use a metal polish called Wenol Red, purely because at one point in my life I worked in an historic building, and it was what they used on all the very valuable metal things there as I was told it cuts through oxidation but without being too abrasive. I know no more than that but if they used.it on 17th century candlesticks then it can’t have been too damaging.
Final touches were to use Olde English scratch repair, bison wax, wax polish and some elbow grease with a soft cloth on the cabinet and all was done! Any comments, thoughts, advice etc would be really great to hear - thank you for reading and I hope this is useful - I’ll finish with a shot of my coffee table during work - I’m just a gal doing this in her living room!
