    Do I have this Speedmaster strut set-up right?

    Below are photo's of the Speedmaster strut for a MM build, I need to know if this is right before I cut and bend the brass, one photo is a mock up and will have shrink wrap at the front nose of the strut and I have a 1/4 inch brass inside the strut to support the bushing, then the .187 brass goes 3/8's inside the front of the 1/4 brass and right up to the bushing. The other photo shows everything apart. Seems right if I had to remove the strut after its installed , then I would cut the shrink wrap and pull the strut away with the 1/4 brass and bushing away from the .187 brass that is glued to the hull.

    That is one way to do it. Make sure that the bushing rotates freely and does not touch the aluminum housing. I drilled the back 1/4" of the strut slightly larger to insure the bushing does not touch it. Remember to have a 3/16" gap between the drive dog and the strut.

      One more thing next to Jay common, I see you step down 2 times with tube size, its will be really tight after you bend it, use the 1st tube size all the way (the short one in the pic).

        Kevin the short one in the pic is 1/4 , if I ran this all the way wouldnt the .187 cable whip around inside it? The 7/32 brass is for a non teflon tube .187 cable, but I do see your point after it is bent, using the 1/4 brass would let the cable run free. I'm going by the OSE drive hardware recommendations.

          Something i did'nt get, by looking at your pics, the short tube fit both bushing and the long tube, is it mean your bushing and the long tube are same size? if yes then its too small for 3/16 flex, btw, use the tube size that you still can fit another tube between that tube and flex cable, cable won't whipping around with full grease in it.

            Let me get this straight, the smaller piece of tube you have is [I]inside[I] the strut? If so that could fix the problem I am having with my strut . .
