Lou....after spending 18 years as our Australian steel industry contract facilitator for cylinders, I am intrigued with the pair of double acting steering cylinders as shown

Lets consider....steer to the right = add pressurised fluid to the blind side of the left hand cylinder and at the same time add pressurised fluid to the rod side of the right cylinder

Sounds simple...yes, however without some form of proportional control, as the equal flow of pressurised fluid will retract the right cylinder faster than the left cylinder extending due to the annular difference or smaller surface area within the rod side of the right cylinder when retracting

PS.....your build looks amazing & I look forward to seeing it progress.............Derek
