Using the measurements provided by Vince I've rejigged the drawing a bit and it ought to be closer. I hope this shows what was meant by the angled corner part, seems logical to have it like that. The radii 'too small to measure' without a gauge was entered as 1/16" and it looks acceptable.
Basic layout, no measurements just a cm/inch scale: http://web.aanet.com.au/~malikoff/pdp11/DEC_H960_stabiliser_foot_left_A-H952-BA_revision_2.jpg Measurements (my CAD program converts everything to metric, when I entered in Vince's measurements): http://web.aanet.com.au/~malikoff/pdp11/DEC_H960_stabiliser_foot_left_A-H952-BA_revision_2_dimensioned.jpg How it might look, so far, attached to the H960 (no kickplate): http://web.aanet.com.au/~malikoff/pdp11/DEC_H960_stabiliser_foot_left_A-H952-BA_revision_2_placed.jpg I had thought the hole in the front corner of the H960 was for a front panel pivot, but it seems the foot does actually use it. I don't have the kickplate nor access to measuring one, so that probably changes it a bit too. Steve.
