Video showing M59 being driven by a guy that I would not label as skinny.
The hatch coaming could be too thick …
I would say that half the thickness would be enough for scale thickness
I measured the width of the M59 and the diameter of the drivers hatch in the picture I posted previously. The hatch is 18.8% of the width of the hull.
lists the width over the track shrouds as 128.5 inches.
Asumption: The track shrouds are more or less the same as on the M113 AND Tamiya didn’t mess up the measurements too badly.
Under that assumption the track shrouds would add 140 mm to the hull width on the M59.
The hull width would thus be 3264 mm - 140 mm = 3124 mm
The drivers hatch (lid) would be 18.8% of 3124 mm = 587 mm.
Based on images in the video I would say that the outside diameter of the coaming is about 560 mm (the lid overhangs the coaming a little bit but not much).
My shoulders, measured over the bony parts are about 50 cm wide and I am 6’4’’ so if the hatch coaming is 15 mm thick (the side armour is 159 mm) it would leave 53 cm of free space to squeeze my shoulders through. Should be enough …
The outer diameter of the coaming would be 16 mm.
The drivers hatch coaming on Tamiyas M113 is 19.5 mm, 22% larger …
Tight but not impossibly tight.
I would exit through the troop compartment and only use the hatch for heads-out driving
