Mods for secondary knobs
Just experimenting with the secondary mirror knobs.
The Bobs Knobs are flat on the bottom, Now i could take them out and grind them to a ball but i decided to keep them flat and place a ball over them.
I found 3 grease nipples in a kit for heavy machinery cut the threads off,Unscrewed the nipple from the elbow.
The knobs now seat in where the nipple was set.
I found i had to do this as the knobs we cutting into the plate on the back of the secondary mirror.Also as i adjusted the knobs it actually turned the secondary mirror around.
My problem is now solved as there is 1 point of contact on each knob without the cutting effect.
Just thought i would give this a mention.
Cheers Kev.
