Indicating my cheap homemade DRO

[engineer steve]

Few video's back I made a DRO from a cheap digital caliper. Today I am checking how accurate it is.

Very interesting, the very slight difference could be due to the saddle shifting side to side when you reverse direction. Looks very accurate overall. If you put the indicator on the same side as the readout the results may be even better. Thanks
