I have a dial indicator holder that looks like this Rube Goldberg cdevice.
Can someone tell me how you attach this to the mill's spindle for checking accuracy of the table? Does the white plastic piece at the bottom bolt on to the spindle?
Red part attaches to the fixed portion around the mill's spindle, clamped by the screw with the white pad. Adjust and rotate the arms until the dial indicator touches the table perpendicularly. Move table around and watch indicator.
Also very useful for making sure a part is straight as you clamp it down.
If you don't have a Bridgeport or clone, this may not work.
I would be looking for a direct digital caliper type for your small mill. Way too easy to loose track of your location when using a dial indicator. Common to misread the overall distance by one or more full sweeps of the dial, where a digital readout will give you total distance at all times. Also easy to bump the needle and loose your accuracy without noticing.
That is a clamping setup. That white plastic is just a soft tip for the clamping screw. I don't think it is intended to be a permanent mounting system, which adds another possible variable in accurate position reading.
