DeltaRed wide front

I built it from scratch cut off like yours .

It steers hard and like a go cart less than 3/4 turn . My spindle arms and pitmen arm I'll call it are close in length to what a A or B wide front would be . Now talked to someone today and he said to shorten the pitmen arm .

The length of the arm attached to the central column (Old vertical steering shaft) is responsible for much of the issue. The length should probably be as short as possible while allowing full left right travel. If the steering arms on the spindles are moving through an arc with a distance (left to right) of 10 inches for example, the central are should be in the area of 5.5 inches. This allows the central steering shaft to rotate through almost 180 degrees, which should allow normal turns left to right. Jim

Agree with Jim. It's all about geometry.The center should be 1/2 to 2/3 the length of the outer 'drag link'.The draglink should use 'Ackerman steering' geometry. Jim can explain.

Check my post in the other "Ackerman" thread. It points to a spread sheet that will help you calculate what lengths/positions you need your arms to be. It takes a little trial and error to get just what you want. But trial and error is a lot easier in a spread sheet than it is in steel.
