First read the instructions for using Downloads that you will find in the Sticky section at the top of this Forum.
Then go to Downloads and drill down below the Atlas/Craftsman folder until you get into A.C Lathes Repairs & Technical Bulletins and look for and download
"Atlas Tech Bulletin 12 Late Back Gear Instr.pdf".
Note that the Sort capability has still not been fixed. There is some conflict between it and the current Xenforo version. The Admins report that they can see the code but have not been able to figure out why it will not display.
