Mounting
The Model G2891 mounts easily on Grizzly Lathe Models G1067Z and G1495. It will also mount on most other lathes having a bed size of at least 40''. Two mounting brackets attach the bed of the Model G2891 securely to the bed of the lathe. The mounting process is as follows:
1.Mount the two bed brackets perpendicular to the lathe bed with the large cap screws and the square threaded mounting plates provided. The heads of the cap screws should be on top of the brackets and the mounting plates should be below the bed.
To provide a solid base for the Copy Attachment base, the mounting brackets should be centered on points measuring 20% of the distance across the bed from the headstock and tailstock. See Figure 2. On a lathe with a 40" bed, brackets will be centered approximately 8" from the head- stock and tailstock. Some minor degree of variation may be necessary to eliminate any interference between the Copy Attachment and the normal operation of the lathe.
The front of the brackets should cantilever over the front of the lathe bed by about 6". Just

2.Slide the two hex head bolts with clamping plates attached into the channel located along the bottom of the Copy Attachment main body. See Figure 3. Place the Copy Attachment onto the bed brackets installed in Step 1, dropping the hex bolts through the bed bracket slots at the front of the lathe. Center the attachment body with the lathe bed and slip the packing block, flat washers, spring washers and nuts provided over the hex bolts and just finger-tighten.
Make certain the Copy Attachment does not block access to any of the lathe con- trols. Some lateral adjustment can be done to assure clearance if necessary.
