Question is, will you have it ready in time for the eclipse Matt?
I only need to cut up some UHMWPE, HDPE and PTFE to get it operational Lewis so I think the 27th will be fine...

Thanks Marc, just working out the eyepiece lineup for the scope at the moment.
Going with N22T4, Delos 14, 10 & 6. That should cover all the bases.
Anything longer than 25mm will have me losing light.
Feel free to maiden view with it at La Course de Golfe
I dare say it might be a regular at Fair Bairn, the other place makes for a too tiring return drive and Yass's lightdome is getting bigger and brighter,,,,

I'm starting to think we need to congregate in the middle of Lake George with the sheep

You guys are welcome to slum it at the Golf Course
Scopes coming along really well Matt look forward to seeing it when its finished.
and I'm sure Lewis is looking forward to playing with your sword
Excalibur is finally free of the stone.....
With only the Nexus DSC and Noctua fan to be added:
Balance worked out as expected (within 25 grams of calculations) with the top end 500grams underweight to allow me to install an optical finder as well as the Telrad....
With the primary mirror focal length just 63.7" or 1618mm the eyepiece height at Zenith is just 1565mm which means it is seated viewing from the horizon to zenith that suits my weary body just fine.
The focuser has been rotated 12º so that when viewing lower objects one is still comfortable
The SIPS Paracorr means the effective focal length is 1860mm making the effective F ratio 4.06.
My plan is for a simple set of eyepieces with the Nagler 22mmT4, Delos 14, 10 & 6 making up a set that will cover from 85x with TF0V of just under 1º to 310x at 0.23º. I also have the APM 30mmUFF for a wider 1.18º albeit with a slight loss of light due to excessive exit pupil....
Mike, there is room to fit the ServoCat quite easily though I probably will not.
I am installing the Nexus DSC and US Digital S6 encoders and will eventually build an aluminium framed equatorial platform....
I have looked at the Osypowski ones and like what I see.... I have lots of aluminium left over (enough to make a another slightly smaller Dob, 12" Excaliburette )
)
