Finally replaced the dried out spirit levels on my Titan 810 pinhole camera. It was pretty easy to break the old vials out and then use a Dremel Tool to clean out the old glue. I used clear RTV silicone to glue the new ones back in, this allowed a little adjustment so the I could “calibrate” the new vials. I figured the silicone it would be easier to replace the vials if any of them dry out again. I also figured my trusty Stabila torpedo level was accurate enough for a pinhole camera. Nice to have this done, only took me about 3 or 4 years to get around to this repair.
