    Looks great. What bearing did you use?

    Looks like JohnnyPro's lime and plumb colored Mammut Serenity.

    I finally had a chance to modify my RR. The 6001-2RS 12x28x8 bearings were going to require resizing the RR pulley axle so I used the 99R8 R-Series Radial Bearings which fit right onto the axle. A couple of 1/2" ID bearing shims I found at my local True Value are between the bearings and the side plates. Current set up is using the baby bump fiction plate. It runs great with out any hoking of the two lines. Certainly an improvement over the HH set up I was using before.

    The ropes are 8mm Marlow Doublebraid. I was having trouble sourcing Sirius 500 and this seem to be a similar spec.

    I am looking forward to working with this a lot more.

    Do you plan on using two foot ascenders ? & have you come across any rope shift issues when ascending.. ?Thanks

    Yes I have been using 2 foot ascenders and yes I do experience some rope shift with an ascender on each rope. I have been thinking of getting a hand ascender like the
    Climbing Technology Quick Arbor Ascender that can grab both lines to see if that helps. John, sounds like you have experienced this as well. Any thoughts?

    I can see its dependent upon your anchor set up , I've just got my Sirius 500 spliced & have the ring & thimble set up , I need some more time on this .. Will post when I know more , you can see from the Johnny pro video by fixing / weighting the ends it stops the shift ..

    The best method to eliminate rope shift on ascent is to move both legs simultaneously, or to set up the initial access as a floating false with the two 8mm lines hung in an eye (prusik/butterfly/etc...) on an access line. Once aloft, relocate the TRT to the desired branch union.

    That, or focus gripping harder on both lines to limit slip when using the foot on the retrieval side. I always set the choke side as the Orange line on the right, and retrieval as the Black line on the left. I just focus on gripping a little harder when striding on the left foot.

    Just wanted to write quick here and say I tried the Twin Bearing mod. I'm not a huge fan since the sheave can allow each rope to run independently. When I set up a dual anchored configuration, I could keep the carabiner connection located where I wanted. It just drifted to center. Other than that, it feels pretty good. The solid flat sheave is the way to fly IMHO.

    Sounds like you will have to go into the solid flat sheave business.

    Well it took three attempts but I finally made myself a solid flat sheave.

    This was cut from a piece of 1 1/4" round stock aluminum and the center drilled out to 5/8" to accept the bronze bushing from the original pulley.
    If the weather clears tomorrow I will give it a try.

    That's what you want, right there. I hope it works out. I recall the bronze bushing press fit into the aluminum isn't too tight. I've actually had a sheave drift to one side on my OG Blue RR. Unfortunately, I don't have the technology to drill that precisely on Center. If it's off a bit, you'll feel it on descent. My welded versions feel off until I finish hand filing them.

    I had to change out Oceans flat pulley to the bearing Runner pulley since climbing on the Petzl Vector. The flat pulley made slack tending heavy and sluggish.
    I made a couple of anchors for the stitched eyes to retrieve through, will post em up later.
    Good work on your sheave, looking forward to see how it performs, Papadirk.

    Surprised to hear that, Paul. I wonder if the diameter of yours came out larger than mine. Tolerances through the RR are brought out by different ropes, for sure. My personal sheave worked well with Vector.
