Claims1
An adjustable hub for rotating saw comprising a hub member for surroundably engaging a motor spindle of a rotating saw such that the rotational axis of said hub member and motor spindle are coincident;
- a ring member having its rotational axis coincident with the rotational axis of the hub member and having a flat bearing surface at an angle of about 45.degree. with the rotational axis of said hub member;
- a first flange member having its rotational axis coincident with the rotational axis of said hub member and having a rounded bearing surface in contact with said flat bearing surface;
- a second flange member having its rotational axis coincident with the rotational axis of the hub member and located adjacent said first flange member for engaging a circular saw between first and second flange member;
- a threaded ring member having its rotational axis coincident with the rotational axis of said hub member and threadably engaged to said hub member;
- at least two pairs of independently adjustable screws engaged with said threaded ring member and passing through said threaded ring member parallel to the rotational axis of the hub member to contact said second flange member, said adjustable screws being located equidistant from the axis of the hub member and from each other.
