Well, you've convinced me Alex. I'm throwing caution to the wind and getting out the power tools..
Seriously though, you're 100% correct, it's the best way to learn. I'll start with some daylight collimation and hopefully the skies will be clear again soon so I can use the star test to get it spot on.
And the daytime work means I can get to know the layout without fumbling around in the dark.
Thanks
Stephen
