Description
Sherline Tall Rigid Mill Column Upgrade (Tall Base) 5645
The Sherline rigid column upgrade (tall base) 5645 is designed for those who have a 5400-series mill. Each comes with the 2000-series ram and gives the versatility of Sherline’s 2000-series mill column with its large work area and seven directions of movement. The tall column provides more Z-clearance. Includes Y-leadscrew cover hole.
Column Design
NOTE: The mounting hole pattern for this column is designed to work with the new mill base that has the thru-hole for the Y-axis cover tube. It will not mount on an older style mill base. If you wish to use this rigid base with an older style mill base, you will need to drill and C’bore the two new holes in your mill base. We can either supply you with the dimensions, or you can send your base in to have it modified for a fee by us. Email us for a print or a machining quote.
The column bolts to the mill base using the same two side-by-side 1/4-20 SHCSs as the normal base, although we include two new ones with each base. The column has the newer style hole through the base to accept the Y-axis leadscrew cover tube. The standard base is the same height as the regular 2000 mill round column. The taller column is the same height as the 2000 round column with the riser block in place.
Installation Orientation of the Rigid Column Base
When it is mounted, the step on the boss should be to the front of the machine (see picture below). This will give you an additional ¼” of Y-axis travel more than the 2000 column.
Everything except the steel rotating disk is from aluminum.
