My astronomy project:
EQ mount with no meridian flip ideas

Content:

1. Introduction
2. First simple drawing of an idea
3. What mount head to use?
4. Base disc
5. Arm details
6. Twin telescope mount
7. Azimuth angle trimmer
8. Summary of the first ideas drawings

Note:
I take no responsibility for what are written here, you use the information at your own risk!

5, Arm details:

I did some complements on the arm design, this is to hold an old EQ6 mount head.

If not too long a rectangular steel tube with dimension 100x100x6mm should be enough I believe.

The arm with its disc plate will be bolted direct on the bolts of the pier.
