Hi George, i have laid a trap for that gremlin, like the last thing that went missing, the special spanner for tightening the tool clamp on the lather QC tool holder. A single ended ring spanner. It turned up quite by chance in a plastic bag under the lathe, I have no idea how it got there. I had looked under there as well.
To read that ANSI doc. I used Adobe Reader X1 which will it seems read any style doc.
