Help with motion travel on Simplex

[ozzie46]

I have all the motion works done except the eccentric rods and when I try to turn the wheels with the radius rod in the center of the expansion link the combination lever seems to be at full travel in the slide valve spindle fork and binds up locking up everything at forward dead center.

Everything is hooked up except the eccentric rod. Is this normal and if not what do I do about it? If I raise or lower the radius rods then I can get the wheels to turn past forward dead center I've remeasured my holes and everything seems to plan, but I don't know.

I had the same problem and just put a chamfer on the lower edge of the fork.

Thanks Russel. I was beginning to think that was what needed to be done but wasn't sure about it.
