metric_taper started a thread http://www.homemadetools.net/forum/s...-holding-60204 over on "Tools in progress" to which I added some pix. DIYer asked if I was going to make a separate post. I wasn't planning it but then I had a job for it this afternoon and made a video whilst measuring.
So for completeness here are the original photos and the video.
This shows a simple rectangular piece to bolt to the lug on the back of the digital/dial gauge. This get clamped in place of the scriber piece of a vernier height gauge.
A dial gauge fitted ready for use.
Here is another way to hold an indicator, useful when there is no lug as with this linear encoder.
And now the video. Note the error, at one point I call out 10.2mm which should be 1.02mm.
