Please Help! Calibrating Lufkin ID Micrometer

It's a mystery!!!!

I have an older piece of equipment in my machine shop that needs adjusted for calibration, (it is .001 shy of it's zero) and I have no clue as to how it is calibrated.

It is a Lufkin inside mic 1.5" to 32" set with the number 681 on the barrel of the larger handle (I assume this is a model number)

There is a hole on the knurled area but it has been 'pinned' so can not access it. I have had it apart four times now seeing if I have missed anything and I even took it to one of my ASQ friends that is a calibration tech. and he had no idea either.

If anyone knows how to adjust this, has instructions from a similar set, or just plain advice because you have done it before please don't hesitate to send me anything you have. It is a nice set and in great condition.

Thanks a lot! Ree

Ree,

I found this at another Forum (Sorry Marc!). It may not be exactly what you're looking for. I'll keep searching for an instruction sheet for calibrating/adjusting this micrometer.

Thanks to Stijloor for your informative Post and/or Attachment!

Re: Calibrating Lufkin ID Micrometer

Thanks for looking, but I already found that too... and followed up on the site that was mentioned without success.

I have even contacted folks selling similar items on Ebay to see if the instructions were intact with any of the sets.

Thanks a lot for your interest though, let me know if any of you find or know anything else.

Re: Calibrating Lufkin ID Micrometer

Did you have any luck with the request form. I have the same issue with a lufkin stick micrometer. The barrel screws off to expose a seating nut but when you adjust, nothing happens cause your not moving the readout.

Re: Calibrating Lufkin ID Micrometer

I have a set of Lufkin OD mics that are calibrated by removing the cap from the end of the barrel which allows you to turn the barrel on the spindle .
