Bit of an update.
As of today we have a working roof drive system at Swan Reach Imaging. There is still some tweaking to do to the settings in the VSD, some cable management and installation of the open limit switch. All of which I plan on completing later in the week when I visit out there again.
I have a video of the roof opening a little and closing on our Facebook page at

I have included some pictures of the drive system in the big observatory for your perusal and enjoyment.
