Default I'm the big wheel around here!

Ozzy. I'm surprised at you. Cranzt says the wheel was made smaller for
the following reasons:


No I didn't.


"The bigger the wheel, the less feel."


This is true for any steering system.


But his posted article only refers to small space for the wheel.


Check the Subaru STI article. No tunnel there.



You
guys know nothing. The small wheel is for the following reasons:



1) Propper space between arms reduces fatigue.


True, but smaller wheels may not accomplish this. Mercedes did a good study
on fatigue and cardiac load with the design of their wheels. What spacing is
optimal for the average sized person?

2) Wheel diameter is proportionete steering ratios.


Not complete. One must consider the load. For a fixed steering system, wider
tires or more camber means larger steering wheels to keep the moment arm at
the wheel the same.


3) Wheel diameter is small to fit driving tunnel..


Only if you are driving a formula car with a driving tunnel . Performance
cars tend to have smaller wheels and tighter lock to lock so the wheel
doesn't have to turn much. Imagine turning the wheel of a 1968 Buick Skylark
through tight turns quickly. Read the STI Momo wheel article. Performance
turning requires quick wheel action.


And Crantz then posted an essay that disputes his original comments.


Not so!

Good work fellas! You don't find small wheels on racing boats because
you need to be able to reach it,


Absolutely correct! In return for the bigger wheel you lose the feel!

rather than drive like a truck driver
on Sloco's Depress 30! It's not about feel.


The bigger the wheel the less the feel!

That said, the R&P system
delivers more feel than cable based and it's instantly obvious once you
try both.


The R&P system is about a 20:1 reduction, any play in the rudder is
amplified by a factor of 20. The actual R&P gear is usually good for very
little play, however, slop anywhere else is amplified through the gear
reduction. This does not happen in properly designed cable systems. Almost
all jet fighters and large transport planes use cable steering. Any play in
the cable will destroy the plane (control surface flutter), yet it doesn't
happen in the trillions of miles they have flown.. That 737 you fly in is
steered by cables. It weighs more and goes much faster than your boat. It's
rudder is much bigger and experiences more force. Your argument is silly and
has no basis in practice.

Ozzy and Crantz think small wheels belong on racing sailboats!!! How
about TWO wheels!!!??


No, I said a tiller is the best. You're wrong yet again!


Your arguments are absolutely ludicrous. You can't even keep things in
context or even get who said what right.

KABLAAM!!!!!





Bwahahahahahahaha!
