First, lightly squeeze the blade with a pair of pliers so that it grabs the ball of the dogbone. While squeezing, heat up the top of the cap (the "apex") with a heat gun or small butane torch. Continue to heat this area until you see it just start to melt. Then, allow the cap to cool as you continue to squeeze it. Performing this procedure will remove the play from the cap and give the cap a bigger contact area with the outdrive, making it last longer.

I actually hold the blade squeze and heat. Seems to work well for me. I run 19T/10.5 and they last about a month when fliped.
