I found rounding the drive flat instead of a more complex jig to make the angle. Instead U found it easier to make Motor Drive to be mounted on an angle.
I have some photos, but I don't know where they are. I am though going to build another EQ Platform as my other one use plywood that was too thin.
A good EQ platform can do really good Astrophotography as well. I did a lot of planetary from my google photo page, although i managed a good Deep Space version -

I will try to locate the photos from the previous build.
