Wringing Gage Blocks
1) Make sure that blocks are clean.
2) Wipe the surfaces of the blocks to be wrung gently across the oiled Wring Pad. (See figures below.)
3) Wipe these surfaces on the dry pad, removing as much oil as possible.
4) Slide the surfaces of the blocks together as shown. Apply pressure while sliding the blocks. The blocks should slide together without any feel of bumps or scratching, and should adhere to each other strongly after being rotated into place.
