@westmarch @FrankRyanJr many thanks for this guide and both your inputs, its my next project after re doing my dob mount. I just have 2 quick questions:
- I have a 12" dob with a 700mm diameter circle base with feet at about 600mm diameter , ive worked out i need to scale the plans 15% for its feet to fit on the top board of the EQ mount, I take it I'm just scaling the timber plans and not scaling the aluminium arcs etc? The 50mm gap between boards stays the same and all rods etc?
- Also, if my dob base has a fixed setting circle on it, if I begin with it aligned correctly, will the EQ mounts movement keep the setting circle aligned correctly or will it all go to hell? Is there any way to get a setting circle on the dob base to work with the movement of an EQ platform?
Many thanks.
