| (...) figure out the steering. This shows it clearly. My preference would be that turning the wheel would give 'normal' steering and tilting it would give 'crab' steering (it seems more intuitive, plus it would be much easier to judge when the 'crab (...)

| Nathan- Thanks for showing how crab steering works. I also like how you designed it, but the fact that it doesn't have a fixed steering wheel bothered me, so I designed one which has. Also, I might impliment this in my realtime version of my crane (...) (20 years ago, 27-Oct-04, to lugnet.technic)

| (...) Yes, it does. It is all computer controlled though. Incidentally, Nathan's design can be used with 2 fixed steering wheels: reverse the rear steering bar, so that tilting the "steering column" now operates crab steering mode remove the knob on (...)

| Ross- Looking at Nathan's crab design, I realized that the center steering mechanism resembles a differential. Realizing this I came up with a sketch (since that's all I'm able to do until I move into a house and open my legos) using a differential (...) (20 years ago, 28-Oct-04, to lugnet.technic, FTX)

| (...) There's a couple of problems with that technique: The clutch gear has a lot of inherent backlash, which will make the steering not very responsive you have to make sure the wheels are centred when you switch the clutch to get back to straight (...)

| (...) Sorry to eavesdrop, but would your revised version of my idea be something I could implement on the telehandler? I thought about moving the mechanism to the cabin. No matter how I do it, the more play in the gears- the less aligned and (...) (20 years ago, 29-Oct-04, to lugnet.technic, FTX)

| Nathan- Do you have a website? If so, what's the address? BTW, I'm having a bit of trouble posting my crab steering sketch, so I just went ahead and sent you the pic via email. Tell me what you think. (20 years ago, 29-Oct-04, to lugnet.technic, FTX)

| Ross- I have designed the gearing mechanism for the crab steering. It is a redesigned version of my original crab steer design. As per your questions about this; 1) I understand the clutch gear has a backlash. I have tried to fix this problem by (...) (20 years ago, 30-Oct-04, to lugnet.technic, FTX)
