Technics 1210 - DISASTER at the powder coaters!!! Posted on: 31.07.2012 by Brunilda Kora I thought I'd found a bargain - | |

| Brunilda Kora 02.08.2012 | I've got a great quote today for all 4 decks, including all of the tone-arm pieces, for wet spraying (2 pack). Gonna do all 4 white this time. That grey didn't turn out as dark as I'd liked... It's a little more than I paid for the powder coating, but they've assured me they'll take it back to the bare metal, and etch prime the deck plates, as well as properly masking up the new tone arm pieces... Fingers crossed this time... |
| Savanna Perimutter 01.08.2012 | man, yeah, they did do a horrible job. sorry dood! unfortunately the bearings are fixed in there, to my knowledge they cant be taken out, they have to be masked off |
| Rolanda Clodfelder 01.08.2012 | I thought the entire bearing array was unscrewable on a technics ? Looks like a right mess there though, even if you got the paint off the top of them it'd still be caked inside them for sure. Even on the bits they were supposed to do, they dont seem to have done a great job, looks "Patchy" No pun intended I swear :P |
| Brunilda Kora 01.08.2012 | Fixed - I hope... |
| Romelia Stankard 01.08.2012 | can't see the second pics/attachments you posted with the bearings upload to imgur.com it works better |

| Brunilda Kora 31.07.2012 | Cheers lotus - I've got nothing to lose, and paint stripper (acetone) was gonna feature heavily in my salvage attempts... Still pretty peeved - these guys should know what they're doing. They let me down BIG TIME. |
| Ira Alsadi 31.07.2012 | Also, don't give up on your parts. With a little (ok, a lot) of patience, you can salvage those parts. Use q-tips and toothpicks to apply acetone to the bearings and pivots. Let stand for 15 minutes and begin to clean up. You may need to use a baby-nose-sucker-thing to remove it from the bearings. Once done, just re-lube as you would during normal reassembly using a silicon based lubricant. The bearings are sensitive to damage but they are simply ball bearings. All normal physics and processes still apply. |
| Ira Alsadi 31.07.2012 | Never heard of blasting cast aluminum posing an issue but I have not had it done. To prep my decks for paint, I use a self etching aluminum primer on the bare metal surfaces. I don't prime or sand the rest as my painter bakes them and therefore runs a slight sand on them in the booth. As for masking, I mask everything myself. After trying to explain my needs to my painter we agreed that it would be better for me to mask it all myself. I also mask off the lower part of the bridge as to prevent rubbing of the swivel and bridge after paint since the tolerances of those parts are very small. As I understand it, powder coating is a chemical process not unlike chroming or gold plating. It may be my ignorance, but I've not heard of spraying powder coating. The reason the coating is tougher than paint is because of the chemical process which chemically bonds the paint to the metal. |
| Savanna Perimutter 31.07.2012 | it is 99% cosmetic, but the blasting and coating does def have a subtle difference on the thickness of the metal, and thus have a lil bit of effect on performance, but shouldnt be out of range of the default technics settings |
| Brunilda Kora 31.07.2012 | Then no - it's purely cosmetic... |
| Ervin Calvery 31.07.2012 | I was asking whether the turntables performed differently in any way. |
| Brunilda Kora 31.07.2012 | piz - I believe next time I'll do the masking myself. Also - anyone know if baking the parts in the oven will affect the bearings? Xone - re: not coating the tone arm pieces - that's crossed my mind many, many times today... |
| Savanna Perimutter 31.07.2012 | yeah, powder coating is a whole other processes http://en.wikipedia.org/wiki/Powder_coating most electronic aluminum is anodized, thats even better |
| Ervin Calvery 31.07.2012 | Is there an operational difference related powder coating versus any other type of paint? |
| Savanna Perimutter 31.07.2012 | Im not sure what they used on mine, i believe glass beads? heres a lil more info… http://www.kramerindustriesonline.co...ting-media.htm i would just call around and tell them what you are trying to do, and just skip anyone that treats you like your dumb for asking about coating aluminum electronic parts… lifes to short fo that bs! |
| Brunilda Kora 31.07.2012 | Xone - no point in pics - it looks like shit. I'm gutted. piz - what kind of abrasive powder/grit do you need to blast aluminium? I'll make sure the next place I go to use it! |
| Savanna Perimutter 31.07.2012 | 1- hmm never heard of this, pretty sure u can blast and coat aluminum all day long. my faceplates and tone arm parts where blasted. I've had aluminum bike parts powder coated maaaany o time with no issue. I bet they didnt have the right kind of abrasive for aluminum blasting, that is more likely. 2 - I taped it off the tone arm parts to show them where I wanted them to mask it, then they went back and did a shittier job, getting coating on my lil bearings and stuff, I had to clean it all up with a scribe afterwards. It was a pain, but it worked out. The fixed little spikey pieces in the swivel parts, I just had them coat those, seems fine coated. If i did it again, I would tape it up myself with vinyl powder coating tape, because I believe I would do a better job than those guys. but yeah, good luck, powdercoating the faceplates i believe is def worth the effort, cuz u know, paint is bound to chip, its only a matter o time. |
| Romelia Stankard 31.07.2012 | Got pics? Couldn't really tell you as i have not had any decks professionally powder coated or painted and I haven't bothered messing with painting the tone arm parts. It's more hassle than it's worth. As far as not being able to sand blast/bead blast aluminum goes. I've done it before and wouldn't hesitate to do it on my decks. Not sure where that comes from that you can't do it on aluminum. |
