Wrong. The units that do not have the housing that extends about 2 inches below the top bell are the friction brake units and do not have the wedge brake. Ham-M has it. Can't remember the model numbe
Joe, I ran into the same problem and finally ended up notching out the sides of the triangular mounting plate. Since I used a thrust bearing I was not concerned with the weight carrying capacity of t

Is the bell the bottom-most part of the rotor or is there another 2 or 3 inch section of rotor (not mast-mount adapter) below the bell? If it ends at the bell, it is an old TR-44 series rotor with a
Friend of mine had a problem with a tailtwister in that it would rotate into the west and then stop. Would not go thru west to south. Only way to get going again was climb the tower and 'help' the ro
