Secondary Tweaking

Recent posts regarding "tuning up" Novak secondary components have been
very helpful. I implimented the cap/socket screws in place of the
Phillips head - with a ball driver, it is much easier to adjust! I
wrapped the threaded secondary mounting shaft with about two layers of
teflon plumber's tape - nice snug fit, smooth to turn. One more
embellishment I am considering is to machine a slot down the length of the
mounting shaft and buy or make one of those special washers with a small
"tang" on it which will locate in the slot (you see this construction on
the shafts of toggle switches). The result is that any torque from
tightening the main nut on the shaft is not transfered to the spider. I
also replaced the main nut with a wing nut which allows for easy finger
tightening. Next, impliment the loading spring idea, possibly with a
teflon washer for the final touch. My goal (other than to play with
neat stuff from the hardware store) is to make collimation easy enough
that I will not dread doing it.
Any one "souped up" the primary mount?
TIA,
Steve
