Update. Both sides have been assembled.. And jeez this thing is big, I keep going back to the 3d model and taking measurements in case there was a mistake.. . Cause I am using a next level gaming seat I have to raise the sides up by approx 95mm (can use the adjustable feet to help). So I am building shaped platforms either side (that's tomorrow's job, along with other things). Also trying to work out how I will get in and out of the pit, as I currently have a banged up knee. Options are to hinge the left side just past the throttle, or remove the last rib and try and slide into the seat from there (seat is currently in it's most backwards position). I am thinking I will make a hinge for easy access. Happy to take thoughts on this.
