Trial of redesigned seat cable guide

The main idea is to replace all rubbing surfaces with roller bearings. The seat adjustment mounting channel ST-CHL-004 has been redesigned and duplicated to support a pulley which holds the cable away from the stop plate ST-PLT-006. This prevents a sawing action which occurs when the handle is pulled. In this post just one redesigned seat adjustment mounting channel is shown. In the final implementation there will be two such channels in each seat, each with rollers to protect the associated stop plate.
