I spent a great deal of time in the past two days getting my table saw aligned using a dial indicator.
I am not convinced i know how to use these things properly given the way the one i have was jumping around. So please feel free to pile in and chime in here and let me know what i am doing wrong.
I made sure to set up my indicator such that it was "loaded" as in point pressed in to around mid way. I was looking for relative reading after having set the dial to zero at one location.
I even changed from a dome shaped point to a pointy shaped point to ensure pin point measurement.
Is that the correct way to use them.
Mine seems to jump around all over the show.
The other thing i found is most are in inches and while i grew up with imperial system I have full grasp of fractions but not when it comes to working in thousands of an inch. 1/64 is where i call halt in understanding imperial system.
SO Mathias Wandel of Woodgears was informed and got me searching for a source for a metric dial indicator and i found one pretty good price on Aliexpress
Then i noticed while searching around on that site they have digital dial indicators and i wondered just how effective they were given i prefer the analog indication of movement over precise digital readout. But on the other hand if one is after a actual measurement this will give it to one without the issue of determining the reading off a fine line markings on a normal dial indicator.
Has anyone tried a digital or worked with one that can add to the merits or benefit of using one over the other.
BTW i see for anyone interested this measuring company also makes the digital scales for using on say a router table or planner at good prices US $25 inc delivery to Canada for a 6 inch or 150 mm digital readout is not bad in my view. The IGaging on Amazon is $35 looks like they come from same stable.
