Ten times better now!
« on: November 06, 2011, 08:16:45 PM »
I am currently trying to figure out how I'm going to true up some wrist pins for use as a pair of cylindrical squares. They are ALMOST perfect, but not quite. While I've been chipping away at this, one of the things I wished I had was the ability to measure to tenths. And then, it somehow clicked!    :Doh:

I have one of these...



And one of these...



And who doesn't have a bunch of these bits of scrapbinium just laying around....



So the design process began, and it slowly took shape...






Until I wound up with this...



I secured the vernier so that the gauge indicator read 0 while the vernier was already backed out .1". This allowed me to move both directions to measure. I am able to set the anvil down on the surface plate with a definite 'thunk' that is more felt than heard, and is far more obvious than the carbide tip that came with it. So now I dial up the head to just above the item I want to measure, lock it in place at a convenient number, and subtract how much the vernier dials down.

With that done, I broke out my troublesome wrist pins and proceeded measuring. I did find a low spot in one quadrant of the first one that corresponded with an area that was apparently worn. (It was much more polished than the other quadrants.) And further, I found that I was getting differences between the inside and outside edges. By this point, I ran out of time, but now that I can measure them, I can map them out and come up with a plan of attack for the surface grinder.  :dremel:

Next up, an attachment to put my DTI on my height gauge.
