- Improved design mill spindle dial indicator holder introduction.
(I forgot to explain how to construct the preset friction joints. If you are interested, have a look at 8 min in. I use spring washers to give the tension, but I bend the spring washer edge that would cut into the surface away a little, to give a smooth contact that does not dig in. You can see the grub screws that pinch on to the thread to lock the friction setting, use soft e.g. nylon or copper inserts in front of these grub or set screws to avoid damaging the threads. This works so well the knurled adjustment screws could be replaced with plain cap screws as adjustment is seldom required).
Looking forward to more in depth video, I'm curious about the friction joints and the spring washer details. Also how to machine the J clamp. Thanks!
Hi Kevin. Sorry these videos were put together when I was short on time. Did you notice the above? (I forgot to explain how to construct the preset friction joints.

Nice refinement w/ centerline positioning of indicator and square cross section link arms, to reduce adjustment issues. Easily adapted for miniaturizing for mini-mill, compared to problems fitting full size clamp. Thanks for the ideas.
Thanks for your feedback. Cheers, Cliff
Yeah, more design and build detail, always 😊 thanks for sharing!
See also the next video. Cheers, Cliff
I like the way it stops central and the friction feature.
Thanks for your feedback! Cliff
I have thought that having one of the arms to be able to telescope might be a good idea? A lever clamp to hold it on the spindle? Might want to have brass where it clamps to the spindle?
So for the friction joints: I think the grubs screws lock on the threads? You took the edge off the spring washers?
Do you think the rounded arms would be better?
Hi - Yes you are correct about the friction joints. (see details above) Rectangular arms are good because they can be set up on center and need no sideways adjustment. Cheers, Cliff
