A lathe can quite easily grab an out-of-round part and make it round. There may be other technical issues with making the reflector as a machined casting though.
In general I agree that hogging these out of solid rod makes more sense at low quantities. I do hope that they’re saving their sharp tools for nice slow finishing passes. Tool wear could certainly explain the bit of variance in the finishes we’ve seen.
Trying really hard not to be that guy, but I paid back in December and my name is not on the paid list. I did get an email from Neil asking for my phone number, but that was close to two weeks ago and I haven't heard anything since. I've been trying to keep up with this massive thread to figure out how the shipping thing is supposed to work, but I can't find anything to inform me where in the process my order is.
You are the same as everybody else. We pay our money and just have to wait. 850 orders went in and 500 have currently shipped. As production rolls along at 150 to 200 lights per week, they are steadily shipping them out.
That makes sense. Can you tell me what FREE site(s) are good to use, if any? I remember searching a few different ones in the past but they all wanted money.
That means I have to break out all the heavy iron from their storage places. That’s a lot of work. But eventually, it will be done. I’m under the impression that typical XBO/Xenon Short Arc lamps have CRI’s in the 90’s. It would be fun to confirm this.
Seriously though, I would be more than happy to measure lots of light sources for people if they send them to me. Send complete lights, bare LED’s, commercial bulbs, whatever you might want measured. I have programmable current limiting power supplies so I can power up bare sources so to speak. Example: LED’s on stars as long as I can get a reasonable sized contact area or u attach wires to it. I can provide Kelvin and CRI/extended CRI measurements and, although I do not quite understand them yet, info on where the source is in relation to:
Thats a pretty cool video on making a reflector, but I really dont think most of the reflectors in the lights we use are made like that. If you notice a page back the pic of the GT reflector, p60, c8 and s2, I would say all 4 of those are turned down on a lathe, not rolled out like in the video.
