Dial Test Indicators (DTI's)

[Andy302]

Im thinking about buying a DTI & magnetic stand to aid the build up of my motor, Ive seen one for not too much (£18 including the stand) which resolves to 0.001" or the more expensive well known makes like Mitutoyo which resolve to 0.0001" for £60 plus.

So is the chepaer one OK for checking the likes of crank end play withon 0.004-0.008 range, seems a simple answer but the max end float is 0.0012" so do I need the 0.0001" unit?!?

Im hoping the cheaper one will be OK, anyone have experience usings DTI's, Ive not used them at all really.

Cheers

Hi there as with all types of tools they have their limitations so if you have to check to tenths of a thou then you should go for the better quality DTI as you will not be able to guesstimate a tenth

Andy, take a look on e-bay they have some good 2nd hand deals on there. You can probably pick up a used Mitutoyo for the the price of a new Draper.

I bought a new "cheap" one with stand and wasn't really impressed with the quality at all. Did the job though.
