And I think it may have worked. It's a JB Weld type of 2-part mix, slow cure. Still waiting a solid 24 hrs before I try it for real, but the bond seems good.
Three nights ago I was repairing a very neglected and nasty Konica Autoreflex T4 for a friend who wanted to shoot it. Had pulled the top plate and prism, removed the viewfinder and cleaned everything. Re-foamed the mirrorbox bumpers. Re-foamed the doors. Cleared the finder, prism and focusing screen. Cleaned all exposed contacts and de-grimed everything as it were. Tidied up everywhere. All was back together, every bit and bob in it's place, shooting happily and smiling at the now clean finder image. The last step, I went to snug the retaining cap that holds the advance lever in place after positioning it back atop the camera and... whilst giving the spanner, literally, the last little "bump" the old pot-metal threaded portion of the cap snapped right off inside the shaft and the cap popped back off. Bricked. Done. Kaput.
I WAS MAD! In no way was the tiny threaded piece recoverable, and in the middle of the advance and transport mechanisms I was looking at a total tear-down and finding a donor camera to boot for the privilege. Not going to happen. I was about to 'paper-weight' it. Then I realized I had nothing left to lose. Such a stupid failure for a camera that was literally finished and ready to shoot with for the foreseeable future. But here I was. So why not. And tonight I epoxy-welded that sucker in place after cross-hatch scoring every tiny contact surface. If the bond takes well, the top plate of this camera is
never coming off again without destroying the advance completely, so this was it's last "service". I hope it appreciates the second chance. And I hope the bond holds and allows for snaps of many photos to come.
If nothing else, it was a kinda fun experience, and the T4 was $12 all-in, plus another $7 for the Loctite epoxy.
Fingers crossed.
