I too am looking for an answer to this, my cross hairs are gone on my Starrett 101 A transit. Not even sure how to take it apart to look at repairing it myself. Just bought it.
This is how I replaced the cross hairs on my David White 8080. Disassemble the tube piece nearest the eye. There is a small ring that holds the hairs, it has small marks on it to indicate where the hairs are to be attached. Use a large lighted magnifying glass. Remove the old hairs. Take some plastic model glue and using a toothpick, place a very small amount on the marks to anchor the new hairs. This type of glue will produce strings or "hairs" when beginning to dry if you use a toothpick to stretch them out. Place some drying glue (several seconds old out of the tube) on one of the marks, and pull the toothpick away (creating a hair) and pull it across the ring to the mark on the other side. Repeat for the second cross hair. With a little practice you can make some very nice cross hairs.
This sounds like it is out of level. Self leveling lasers are only self leveling to a point. If they go past that they can not compensate and generally flash to let you know.
Hi, There should be a convergence adjustment on this set. It will have a "cross hair" type pattern You adjust the beams so that the cross hairs turn white. I believe Green is not adjustable intentionally. The procedure is to adjust the vertical Red line until it alligns with the Green line. Then adjust the vertical Blue line until it lines up with the Red and Green. The line should turn White. Repeat the procedure for the horizontal lines. When you return to regular viewing mode the double images should be greatly reduced or eliminated.. Hope I've helped you, Best Regards, Mark
Yes there is, but I don't think you can do it your self. There are places that fix nothing but levels and transits. I don't know what happened to your lines, must have been dropped or something. I had a level repaired once, it was fairly cheap. I would contact Berger first. Hope this helps.
I just assisted a friend "re-calibrate" his D.W. L6-20 Level Transit. Follow the following steps. 1. Set up the tripod & transit in the garage. Get the platform with the protractor, close to level. 2. Position the telescope at "0". The telescope should be over 2 of the adjusting screws. 3. Adjust the screws to get the top bubble close to level. Adjust with a screwdriver the spring loaded screw to get the bubble closer to center. 4. Rotate the scope 180 degrees. Note the difference in the bubble position. Split the difference from the first bubble location by adjusting the same top screw. 5. Rotate back to 0. Adjust the same top screw to split the difference in bubble position. 6. Rotate back to 180 degrees. The bubble should be off by the same amount. Adjust the 2 bottom screw to place the level in the center. 7. Rotate back to 0. The bubble should not move. 8. Rotate to 90 degrees and adjust the 2 bottom screws to place the bubble in the center. 9. Rotate to 270 degrees. The bubble should be centered. 10. From this point on, all you need to do is place the level on the tripod and position it over your reference point with a plumb bob. Adjust the bottom 2 screws at 0 and again at 90. The level is set to use.
