[ATM] Wire Spider Vibrations

[Chris Dalla Piazza]

Er, oh yeah.

My scope is an old 10" Meade Starfinder that had the secondary glued to the
collimation assembly with a threaded rod coming out of it.  I opted to use
this intact and got an end cap for the PVC.  Then I simply drilled a hole in
the end cap and screwed the existing secondary assembly into the end cap.

I also had to cut three chunks out of the end cap to allow access to the
collimation screws.

Not very elegant but it works!

I imagine most secondary assemblies are bolted onto the center of the spider
using a threaded rod so this would probably work with most secondaries
without having to reinvent the collimation assembly.

Thanks for the info Chris, but I was actually attempting to ask how the 
mirror, rather than the wires attaches to the PVC.

Clear skies.
