GERBER 506 cylinder machine

Do any of you lab techs know of an axis calibration gauge that goes into the lap table and then you clamp the lens pins into it and the tool's "arm" moves to tell you how far out of calibration your axis is? I had one at another place and I don't really like the "grease the block" and "eyeball the to blocks to see if you are on axis" deal. The swing arm type seems to be more accurate and I would like to get my hands on one. The thing is Gerber, OWC, DAC and PSI don't have one (that they know of). But I know that they are around.

You might want to check with Pat McCoy, Mary Larson, Glen Fluegge, all are used equipment rebuilders and may have one. Also contact Barry Sheppard about this. I think you will have more luck finding one on the used market.

Actually, the flat pad that you describe has been around for years and years and it works. Instead of eyeballing it, use your fingers.

Open the machine base and rotate the lower spindle so that it is in mid-rotation. Align the block with the base and slightly tighten the pin bolt.

Rotate the lower spindle and check by feeling the block alignment with your fingers, then rotate in the other direction and do the same. By making three or more of these with slight adjustments you will get the pins realigned with the base.

Then don't forget to use the larger flat to check the pattern of the movement. This will show you if the machine is grinding too far forward or backward on the tool and is also an excellent way to test the final setting of the alighment blocks.
