Cool !!
Keep us posted on progress and ask anything anytime. The only 'factory' components on my scope are the mirrors, the focusser and the red dot finder.
I gave up trying to build a 2" Crayford but it's always on the cards and I've still got ideas about building a 'Telrad' type finder. I WILL definitely build an finder scope with illuminated reticle and right angle EP.
It's all good fun I tell ya
