Used good to top quality tools can often be had used for less money than an unusable cheapo costs new. In this example, the spindle is run to its zero position on a 1" gauge block, and the thimble is positioned for the desire reveal of the graduation lines. This may release some tension and allow some motion, then the unit will need to be calibrated. Great write up, if I had seen something like this at a thrift shop or garage sale before I would probably have passed it up without a second thought. This is mostly time. Abrasive paper can be used, but it is awkward to get in, and getting rid of the residue can be difficult. Work it both ways (righty-tighty and lefty-loosey). With the threaded nut fully remove the 3 fingered sleeve is still extremely tight. No tools for this. A fairly sensitive adjustment of friction can be made, and the wave washer provides enough friction to hold the adjustment well. Follow up with a drop of oil applied with a pin. A small drop of oil on the threads and run the spindle in. A minimal drop of oil on the outer surface near the lead end is all of the lube it takes. Bamboo skewers, cotton swabs, and mineral spirits are good for this. The screw threads were cut on an Aureole thread milling machine and finished with a lathe tool. The Tubular Micrometer Company and Scherr-Tumico designs are quite different than any other manufacturers. When inspecting the tool, two things come in to play: visual inspection and tactile inspection. Let's examine the evaluation, repair, and adjustment of a second hand Starrett model 436, one inch range, 0.001" resolution caliper.
