OLD PARTS AS STANDARDS
Here is a quick way to double check you settings on your Dial Bore Gauge or Sunnen AG-300 Rod Gauge. If you have an en­gine you work on all the time, make a simple standard from old parts to make sure you are set up correctly. I took a couple spare main-caps for a Small Block Chevy and cap cut a substantial amount off them. I both bolted and welded them together to secure for good. I sized them with my boring bar and finished to size on a hone. I paint them different bright colors and write their size on them. You can make a selection of main caps, or connecting rods for the common engines you work on. The chances of someone misreading a micrometer during set-up is pretty much eliminated.
