Although you are supposed to use formica on teflon for side bearings in a classical dob, Tech 2000 recommend aluminium for the Dob Driver kit, the kit comes with various bits of hardware including some virgin telfon and bearings. For this I acquired some 1000mm x 30mm aluminium strips and used contact adhesive to glue these onto the side bearings. The side bearings are made from two sheets of 15mm ply bonded together and routed into the correct shape using a template which was a 600mm diameter semi circle.

Here is one cut, sanded down and glued to the aluminium bearings.
Side bearing on the scope.
