Extended reach Dial indicator

[Neil LickfoldParticipant @neillickfold44316]

This is what a made up to enable an extend DTI down a hole to indicate it concentric to the front. As pictured, it was set on the front, as a check for it's effectiveness. It was within 0.02mm of the indicator being on the front of the hole directly. Then it was travelled down the bore to see what the run out was 220mm down the hole. In this case, the bottom of the hole was then zeroed, as well as the front of the hole zeroed. Then the out side turned concentric to these values and a new datum being established to then make the part as concentric as possible to the inner hole. In this case the correction was 0.1mm on the DTI.

Nicely thought out setup!
