I fitted the latest test blank assembly to my DEC axis
of the homemade GEM to see how smooth it drives
with the existing DEC stepper/ geartrain.
I made two pressure plate flanges with rebates
cut into their faces for two large cork washers to sit inside.
I used old cork placemats for the washers.
This is another great suggestion from Dave G!
The M6 pressure adjustment bolts you can see in
Pic 2 act directly on the masonite backing of the placemat
cork.
The whole setup was only temporary to get a feel for
the 'stiction' and brake effect of the pressure plates
and the ability of it to protect the worm wheel from
a bump.
The setup worked beautifully.
I am so impressed with how snug this feels and works as a
brake/clutch that I will now do a proper job of the 'temporary'
pressure plates.
Next: on to the RA Axis !!!!!!!!!!!!!!!!!!!!!
