Figure 3 1 5 Figure 3 1 6 Attached to the top side of the easel base are two pieces of 80 20 10 series aluminum extrusion Figure 3 1 7 that run from the front to the back These pieces of extrusion are attached to the easel in the front via aluminum end caps that are welded down Figure 3 1 8 and in the rear by a piece of angle and two self tapping screws Figure 3 1 9 48 Figure 3 1 7 Figure 3 1 9 III Floating Base The floating base sits immediately atop the base of the easel and is connected by four 80 20 6725 10 Series Double Flange Linear Bearings Figure 3 1 10 that ride in 80 20 10 Series aluminum extrusion These four bearings allow for the easel to move in and out 6 inches while safely distributing the moment generated by the extension of the easel beyond the table Figure 3 1 11 In the rear left corner of the floating base there is a special 6425 10 Series Double Flange Linear Bearing that allows for a locking handle that holds the floating base locked in place Figure 3 1 12 49 Figure 3 1 10 Figure 3 1 11 Figure 3 1 12 The majority of the floating base is constructed from 2 inch aluminum angle As seen in Figure 3 1 11 there are holes drilled in front of the floating base through which the pivot pins will be inserted to allow for the tilting and attachment of the easel frame Figure 3 1 13 Also attached to the underside of the floating base is a third piece of 80 20 extrusion Figure 3 1 14 to wh
