I think Jim means this, http://www.ebay.com/itm/80-20-10-Ser...item56477386f4
This seller has a lot of track. I plan on following Jim's plan one day, but now I just research...
Tin Can
Lexan is Polycarbonate, Plexiglas is Acrylic. Polycarbonate is tougher, but scratches more easily.
Lexan and Plexiglas are trade names, like Perspex in the UK, which if I'm not mistaken, is Acrylic.
Each material has it's own characteristics. I have used Acrylic focusing screens in ULF cameras for 30 years, starting with the original Polaroid 20x24s, and continuing with my own productions.
Jim, no worries. Between your description and Randy's link, I think I've got it.
Thanks!
This is all very interesting, but I still don't understand why all Jim's building projects are placed here in ULF Cameras rather than the DIY section. There is an awful lot of material/process information and discussion which is just as relevant for building 8x10" and smaller cameras. Sorry to break into the discussion!
Steven, you make a good point, but I don't think we are going to get perfect classification of threads. Over in the Image Sharing Forum, there are separate threads for 5x7, landscape, flowers, etc. So, someone could post a 5x7 landscape in the 5x7 thread or in the landscape thread, etc. Likewise, this sidebar discussion could be taking place in the Feedback forum....
I appreciate Jim making this information available, wherever it is placed.
Steven & Michael thanks. I just build cameras because I love to. I know that this one because it is a 14 x 17 belongs here but I agree it could go here and in the DIY camera building section as well. I haven't checked where my 8 x 10 build went but I would assume it would be in the camera building DIY section. 4 of my 5 camera builds are ULF so at least I know where to put them should I decide.
So for anyone interested, here is the link to the 80/20 that I used for the 14 x 17 - 20 x 24 that I built the frame, front standard, rear frame and rear tilt arms with. If you look at the slot in the channel Michael they have a T type nut that fits in there and when tightened is very stable.
