vinntec Posted September 18, 2013 Share Posted September 18, 2013 Now we have sorted out the cracked lens in our Strand Quartet PC, we still have an issue with the reflector that has been polished as well as we can do it but is not working 100%. We are getting a decent amount of light out of it but with slight vertical lines (which are noticeable only if you are looking for them). If anyone happens to have a Strand Quartet or Prelude PC.Fresnel in their junk pile but which still has a decent reflector going to waste, please can you let me know and see if we can do a deal? This is to use the lantern in a theatre, not as a vintage item! Peter Link to comment Share on other sites More sharing options...
gyro_gearloose Posted September 20, 2013 Share Posted September 20, 2013 Chrome-plated Aluminium reflectors. What a daft idea. The Chrome and Aluminium expand at different rates when they are heated, so the Chrome will eventually become a dull grey and reflect very little light. Its a long shot, but how about finding a company who can make you some out of stainless steel. You'll need to find someone who knows how to spin metal as its something of an art form. Failing that you could look around cookware shops to see if you can find a suitable ladle that you could cut the bowl off. Apparently this is quite a common approach by the DIY projector crowd.

We could replace the whole thing with a complete lantern on EBay for less - or even a reconditioned one on Usedlighting for not much more - than having one reflector resilvered.

You first need to reverse chrome-plate the reflectors to get the old stuff off. Then you need to polish the aluminium bowl to a mirror shine. Finally you need to re-chrome the bowl. Hence my suggestion of getting some spun out of stainless steel, or raiding kitchen to see if you can find a suitably-shaped ladle. The things we do to keep old lamp stock from the skip....

vinntec Posted September 23, 2013 Author Share Posted September 23, 2013 To close the loop, I have two reflectors on their way from White Light which will fit Quartet and Prelude F or PC. White Light still have some stock if anyone is interested. Peter Link to comment Share on other sites More sharing options...
vinntec Posted September 25, 2013 Author Share Posted September 25, 2013 As you were! It turns out the reflectors White Light have are for Quartet Profile, not PC/F and no they don't fit Preludes. So if anyone is looking for a Quartet Profile reflector, White Light have some right now. Peter Link to comment Share on other sites More sharing options...
