Put the control column together, had one hiccup when I snapped a drill bit off in one of the holes holding one of the sticks on.took a while to remove. I had to put the idler arm on the other side of the idler to that shown on the plans to make it square with the control column. I also had to increase the length of the holes in the seat to clear the sticks, not sure why the cutout's are so wide though.
