Hi Folks, Last week i subjected my old faithful rd1 to what can only be described as equivalent to 30 seconds with Tyson, it falling about a dozen sets of steps - one by one. By the time it jumped from the third to fourth step i was then watching in slow motion and had resigned to the fact that the rf alignment is probably going to need a damn good 'trim' to get it back in shape. How naive...
To my surprise though very little damage, just the hood of an old canon serenar taken a little dent. I put it to my eye and indeed the rf patch was now sitting near the top of the window, i'm thining several turns on the vertical needed to sort this one
So was my first reluctant time with the top of camera plate off (i am no watch maker) and only damage i can see visible is a tiny piece of glass chipped off the top right corner on the front viewfinder glass, im sure nothing of worry there, but the entire block is a little loose. This block (you can see in pics on Rich Cutlers site and elsewhere) is a cube about 15mm square and is obviously the main prism. It lifts and now has approximately 1mm of play in each direction.
It clearly neads to be seated properly as the slightest movement of it moves the patch about by large amounts (much more than that achieved with the screw adjustments). I have the top back on it now as i was going to send it back to epson europe but that is a task easier said than done and it will no doubt a couple of hundred pound
Now that i'm a bit more familiar with the guts and assembly of the camera i'm thinking to try and repair it myself - surely a little glue to hold this block in (the right) place is all thats needed.
Does anybody have experience of how this block should sit, type glue to use etc??
From what i remember it is not so clear as to how the seat of the block seems to hold block. If anybody knows about the geometry/ locating precision of this block i would be very gratefull to hear from you.
many thanks, jon

Well-known
Other people might have suggestions about what to use, but I read somewhere that it's important to use water-based glue, otherwise (especially with things like superglue) the glass surfaces will fog up very quickly with a residue. I followed that advice when I fixed the VF/RF in my Lynx 1000 and it went back together clean as a whistle.
I used some standard craft shop water-based cement, not very strong I would guess and there's probably something much better, but if anything goes walkabout I'll just pull it apart again. Easier to say something like that when your camera only cost $20
