The Sherline Lathe Riser Plate Instructions (P/N 12940) provide guidance for users who have upgraded their lathe with an 8-inch crosslide, replacing the standard 6-inch version. This riser plate is specifically designed to elevate the headstock by 0.250 inches, aligning it with the increased thickness of the 8-inch crosslide. This adjustment ensures that standard tool posts remain on the centerline with the headstock, facilitating precise machining operations.
However, users should be aware that the tailstock will not align with the headstock when this riser plate is in use, which precludes the possibility of turning parts between centers. Additionally, certain accessories, such as the thread cutting attachment, are incompatible with this setup. While the 8-inch crosslide is considered structurally sound, using a 13-inch mill table as a crosslide is not recommended due to potential structural integrity issues. The lathe saddle was originally designed for a 6-inch crosslide, and extending beyond 8 inches may introduce undesirable play at the ends of the crosslide.
Note: Ensure the lathe is securely mounted to a stable work surface if using a longer table to accommodate the added travel.
