Dial indicator holder for height gauge
« on: January 29, 2017, 08:55:09 AM »
I have micron DTI (Dial gauge type) that has beem turned bit too sensitive for normal magnetic bases, it bit bigger and heavier than normal "clocks". Adjustment is not stable and any movement will cause error on repetitivity.

I have cheap but heavy scriber srand of height gauge type. I woke up early this morning and I was staring the scriber. I got the idea od simple DTI holder that replaces the scriber.

Three holes and some milling later I have this. Pitty I don't have a grit blaster (cabinet) and small thingy to heat blackening solution.

Seems to work and least it confirms that the clock has some use.

Nicely done.  I like the small detail of the shoulder cuts ending in a radius.  Little things like this make for much better "feel" in the hand for tools, and it's something the Asians haven't quite figured out yet.

I made a similar holder for my DTI a while back that clamps on the dovetail.  It was made so the clamp was on an angle so you can see the dial a bit better and/or present the stylus to the work in a more favourable way.  Clearly not an option for this style of indicator, but may give you some ideas for your next project.   When I made that one, I made a few blanks at the same time for "future" holding needs.  I may use one of those to make a similar holder to what you've presented here.

Thank you, these are always specials.

No matter how simple part looks, there is always something to learn....I made the hole for flexure (the hole at end of the slit) first too small. Needed to turn the know with white fingers to compres it enough to hold the indicator - mildly...Poked it with 10 mm end mill and better, shaved off annother 0,5 mm on each side and I called it good....

Glad you got it sorted out.  On a related note, if you'd have located the clamp at the open end (leaving that area a little bigger than it is now), leverage would be on your side for clamping power.  But maybe there's a reason you went the way you did.  Designing things like this "by the seat of the pants" is tough.  Sometimes you get it right the first time, sometimes not.  Every experiment adds to your knowledge and experience.  It's all hindsight, and you have something that works now.

Thank you

Any ideas how to make stand an/or adjustment for a micron gauge or microcator?

Use a micrometer head to move the gauge against a spring loaded mount for the gauge.
Just get doing and make swarf, you can decide what its going to be later.   :thumbup:
