Page I.3: Corner pillars

Now I have come to the part where I need to stabilize the pillars, they must be holded in exact position.

Here are the pillars bolted together in the bottom frame. This was my first attempt, later I have cut the pillars down to let the telescope reach lower altitudes. Maybe I can come down to about 30 degrees above the horizon, in southern direction even lower than that.

Before bolt the upper end together you must have the frame in level, I used a spirit level and adjusted the base like this. There are two wedges that you put together or apart.
