Jimani has been using the Sherline X-Y table on the Langolier workstation for a while, see example here.
Open Table Langolier. The tooling plate has dual purpose ¼” holes, on 1” centers. These holes are threaded ¼-20 on the bottom and reamed to ¼ on the top. This allows each hole to be used as a “part locating” hole when you insert a ¼” dowel pin. Each hole can also be used as a clamping hole using the ¼-20 thread.
In addition to the ¼-20 holes, the plate also has 10-32 holes which are positioned to mount the rotary table and tilting angle plate.

Sherline recently modified the X-Y table manual to include a section on lubrication. The new manual is now available on the Jimani website by clicking here.
