Bush DAC90A Dial glass
Can anyone help to guide me towards where I can obtain another or repro dial glass for Bush DAC90A? I am so angry with myself. I tried cleaning what was my mint glass. I used a cotton bud and applied virtually no pressure at all to clean with water. The bud was barely damp, but some of the paint has come away. Its not bad but now I know its flaked in tiny areas, I not happy. I heard that you can get repro glass dials that actually very good match to the orignal?
Thanks guys |

Re: Bush DAC90A Dial glass
There's a greek guy who makes better than original reproductions, can't find his details at the moment but others here may have them, I'll keep looking.

Re: Bush DAC90A Dial glass
You can make one.
First download the image from : http://www.pasttimesradio.co.uk/dials/tuningdials.html You will need some A4 transfer paper, you can find it on Amazon or eBay, I used this: https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1 You need to take the image and mirror it (MS paint or similar will do that) and then print onto the the transfer paper. I found I could fit 3 or 4 images onto a sheet so you have some to practise with! Check the image scale is correct so it will fit on your dial glass. With mine (a DAC10 dial) the image was exactly the right size, I don't know if this was a fluke or if the images had already been sized to fit. Once printed, spray about 4 coats of clear varnish onto the printed side. This helps protect the (fragile) transfer. Wait about 15mins between each coat, then let dry overnight. Clean your old dial glass thoroughly - a green scouring pad should get it clean - then put it in a tray of clean cold water in a suitable shallow tray, then carefully place the transfer in and wait about 30 seconds till it will slide off the backing paper. Gently position the transfer on the dial glass. You can use the backing paper to gently press the transfer to make sure there are no air bubbles. Drain the water and take the dial glass and put it somewhere to dry overnight. |

Re: Bush DAC90A Dial glass
Don't feel too bad about it. We have all done it! I learnt that lesson with a pre war Philips in 1961 when I was 13. A lesson learned. Without mistakes, how do you learn anything? John.

Re: Bush DAC90A Dial glass
Did you try the pasttimes link in my post #5? If you scroll down and select the link DAC90A(All) you should get a zip file with a few variants of the dial.

Re: Bush DAC90A Dial glass

Back in 2013 when I first started experimenting with waterslide transfers (decals as they're more widely know), I obtained several scans of different DAC90A dials and other dials such as the KB FB10. I reversed the scans and created transfers on clear film on my ink jet printer which looked excellent while still on the white backing paper. However, when applied to the rear of the glass and held up to the light, they results were disappointing - nowhere near the level of opacity called for. Likewise, the KB FB10 'Toaster' dial was equally disappointing, (as was a Murphy U198). You'll see that the scans look solid enough The reason that this happens is that the transfers are meant to be applied to a solid background - typical images will show them applied to white mugs and plates or model cars etc. In that regard, I've had successful results with clear decal paper when applied to solid surfaces such as a painted metal dial, a metalised valve, a re-stuffed and refurbished smoothing capacitor can, which I've shown pictures of in a recent thread here, but that's of no help to you with your DAC90A dial: https://www.vintage-radio.net/forum/...d.php?t=165911 I've no wish to discourage anyone from having a go - nothing ventured, nothing gained. I've attached scan of various DAC90A dials I experimented with and if it would help, will happily email the scans to you in reverse, ready to print. To try to improve the 'opacity', I thought maybe if I applied a second transfer over the first it might have a successful outcome, but it didn't, apart from the fact that it was impossible to 'register' the two images accurately. The instructions will tell you that after printing, you'll need to apply several coats of clear gloss acrylic lacquer allowing it to dry between coats. You need the best dust-free area you have - I have a greenhouse so spray in there, but if you need to do it indoors, when you've sprayed the sheet, cover it with a box or plastic container to stop dust settling on it. I leave it overnight to fully dry between coats. For extra durability, when you've applied the transfer you can give it a coat on the rear. Applying larger transfers such as the DAC90A dial is an acquired skill. When you've soaked it in warm water, holding it down so it doesn't curl up, you need to make sure by testing between your finger and thumb that it will slide easily without stretching. Don't slide the transfer off the backing paper or it will wrinkle up. Instead, hold the transfer, still on the backing paper, where you wish to apply it, then gently slide the backing paper from beneath the transfer taking care not to stretch the film, smoothing it in place as you go. It helps if you wet the glass first so you can slide the film around a little to position it exactly before you smooth it down, excluding the water and any air bubbles. You should be able to fit four dials on an A4 sheet of paper to give you several attempts. Pic 1: Early brown DAC90A dial. Pic 2: Later DAC90A dial. Pic 3: Alternative DAC90AS dial. Pic 4: Front and reverse scan of a KB FB10 'Toaster' dial. Hope these notes might be of interest and help a bit. Every success in your efforts.

Re: Bush DAC90A Dial glass
The opacity of transfers is not perfect, David, but with the dim scale bulbs I didn't think it was that bad! Way better than the damaged original. Yannis's dials are nice but he doesn't offer one for the DAC10 I was renovating.

Re: Bush DAC90A Dial glass
I have just sent off an enquiry to a company that does digital printing on glass for exhibition displays. Anyone investigated this before?

Re: Bush DAC90A Dial glass
Hi
It might be worth contacting Ben Dijkman and asking if he could help. I expect he would need an order for a large quantity in order to make it economical though. The quality of the reproduction dials he produces is outstanding. https://www.bendijkman.nl/ no connection just a satisfied customer. Regards RT |

Re: Bush DAC90A Dial glass
Ben's dials are superb and keenly priced, as are his back panels, speaker fabric and knobs, though as might be expected, are mostly for continental radios. I bought one from him for an Ekco AC77 some while ago. Top quality screen printed, though with continental spelling - eg, 'Londres' rather than 'London'. He said that if I could get 25 people to order, he'd have printed one with station names in English.

Thanks for this great information as well. I will still have a go for sure. As you say "nothing ventured, nothing gained" I will certainly add photos of my attempts. I will be a good learning curve Thanks again |
