The guide rail further includes a race insert mounted against the at least one finger. In an embodiment of the invention, the race insert has a first and second raceway associated with the at least one finger extending from a portion of the channel. Further, the first and second raceways have different load transmission directions, wherein the load transmission directions of both the first and second raceways are oblique to the direction that the at least one finger extends from a portion of the channel. ## Claims ### Claim 1 A method of forming a guide rail comprising the steps of: forming a channel within a base rail, wherein the channel includes one or more fingers extending towards an opening of the channel; and fixedly mounting a race insert, having two raceways angled with respect to each other, within the channel such that the race insert is pressed into contact with each of the one or more fingers; and wherein mounting the race insert includes deforming each of the one or more fingers in the channel such that each of the one or more fingers is biased against the race insert. ### Claim 2 (depends on 1) The method of claim 1, wherein the step of mounting a race insert having two raceways comprises mounting a race insert having two raceways, wherein each raceway has a different load transmission direction, and wherein mounting the race insert includes inserting the race insert into the channel along an insertion direction, the insertion direction being oblique relative to the two load transmission directions. ### Claim 3 (depends on 1) The method of claim 1, wherein the step of forming a channel within a base rail comprises forming a channel within a base rail, wherein all of the one or more fingers in the channel are generally parallel to one another prior to the step of mounting. ### Claim 4 (depends on 1) The method of claim 1, wherein the step of mounting a race insert comprises mounting a race insert comprising: a column having an end that is joined to a beam at some point between the ends of the beam; wherein the column is recessed on each side where the column is joined to the beam; and wherein each end of the beam includes first and second raceways that come together at an angle such that the ends of the beam are V-shaped. ### Claim 5 (depends on 4) The method of claim 4, wherein the step of mounting a race insert comprises mounting a race insert, wherein the column has a barb on each side of the column, the barbs configured to penetrate and anchor into sidewalls of the channel and the beam has a spike on each side of the column, the spike extending in the same direction as the column, and wherein the spikes are configured to force a portion of the base rail in the recesses. ### Claim 6 (depends on 5) The method of claim 5, wherein the step of forming a channel within a base rail comprises forming a channel within a base rail that includes two mounting grooves formed therein, each mounting grooves configured to receive a spike ### Claim 7 (depends on 1) The method of claim 1, wherein the step of mounting a race insert comprises mounting a race insert comprising a column joined at one end to a triangular head portion that includes first and second raceways which come together at an angle such that the combined raceways are V-shaped, and wherein the column is recessed on each side where the column is joined to the triangular head portion. ### Claim 8 (depends on 7) The method of claim 7, wherein the step of mounting a race insert comprises mounting a race insert by one of staking the race insert into the channel of the base rail and swaging the race insert into the channel of the base rail. ### Claim 9 (depends on 1) The method of claim 1, wherein the step of mounting a race insert comprises mounting a race insert having a V-shaped profile. ### Claim 10 (depends on 1) The method of claim 1, wherein the step of mounting a race insert comprises mounting a race insert having an arch-shaped profile. ### Claim 11 (depends on 1) The method of claim 1, further comprising forming the base rail from a first material and forming the race insert from a second material harder than the first material. ### Claim 12 (depends on 11) The method of claim 11, wherein the first material is aluminum and the second material is steel.
