is of hollow metal tubular construction although other types of construction would present little barrier to the use of the invention which as presently constituted anticipates that a casing for the aid 10 will telescope into the top end of the shaft 14 and that the wrap 18 will then be applied to cover the shaft and some portions of the casing with reference now to fig2 the major parts of the invention are the casing 20 fluffing tool 22 and ball marker carrier 24 the casing has a cylindrical lower end 26 having for example an outer diameter of one half inch and an axial height of one and one half inches terminating at its upper end with lip 28 having suitable width to engage the top end of shaft 14 and thereby limit the degree to which the casing can be inserted into the shaft immediately above the lip at mid section 30 the casing flares radially ouwardly and axially upwardly for example at thirteen degrees to the vertical axis of the casing and for an axial height of 1 125 inches whereupon the casing again becomes a vertical cylinder at section 32 this time having an outer diameter of 1 125 inches and an axial height of 0 218 inches the inner construction of the casing is best understood by reference to item 20 of fig2 in combination with fig3 an axial bore extends through the entire casing and has a varying diameter at the immediate bottom the bore has a 5 16 inch.
