Vertical Stops

Vertical stops and Teflon Brake:

I built vertical stops out of felt-lined BB cutouts that Steve used to stack mirrors for the purpose of locking the telescope in a vertical position when not in use/stored/transporting. I veneered the vertical stops, and epoxied washers on them. These use the same studs that the wheel barrow handles go on.

I installed roller bearings from Taj and Dan @ Sidereal Technologies because the motion on both axis was stiff, extremely so. It was at the point where yes, it was balanced, but unusable because of the stiff motion on both axis owing to the mass/weight of the optical assembly.

The rocker has one roller bearing assembly paired with a teflon pad on each side, and roller bearings at two locations on the ground board with the 3rd location being a teflon pad.

This necessitated the use of a variable pressure teflon brake, which I veneered out of a BB cutout that Steve used to stack mirrors.

The veneer I chose for this project is Cerejeira, for its seam hiding abilities.
