The washers are made of spring steel and 'dished' so that when torqued correctly, they exert some axial load and therefore retain tension to accommodate the wood moving with changes in humidity etc. A stack of Bellvilles allows a greater tolerance of movement. In the case of the GT propeller, which uses a denser wood, you don't need them unless specified by GT. The same goes for all other prop. manufacturers; use their specified method of mounting. We stock the Bellville washers for use on Jabiru props. Andy Silvester -------- www.suncoastjabiru.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=37783#37783
