Steering wheel hack questions...

hatrick:

Here's the details:
I have a Chase HQ wheel that is an optical wheel, but limited to 270 degrees of motion. I have removed the optical doodads and am planning to place a pot on it to make it an analog wheel.
So here's my question: Can the pot be attached directly to the shaft of the wheel? It's a 300 degree pot, and the wheel is limited to 270 degrees, so I shouldn't ever hit the endpoints and damage the pot. 
That leads to another question, why are all of the pots on arcade wheels gear driven rather than connected directly to the shaft?

Anyone ever done this mod before?

Thanks.

Wow...lots of activity on the board today. My topic is sinking like the Titanic. 
One of you arcade geniuses HAS to know the answer to my question...

Rocky:

I made a pot based wheel and mounted the pot directly to the end of the shaft. I didn't want to try and mount the gears.

Just make sure that you mount it so the wheel hits the end points before the pot gets to the end of its range.

Good luck,
Rocky

Thanks for the reply, Rocky.
That's exactly what I wanted to hear  ;)

  Might be better to use as optical,  as most games that steer can accept mouse (optical)  input to control them.   However, you can not play a classic like pole position with an analog, because the wheel will not spin all the way arround.

So here's my question: Can the pot be attached directly to the shaft of the wheel? It's a 300 degree pot, and the wheel is limited to 270 degrees, so I shouldn't ever hit the endpoints and damage the pot.

  I do not think there is a 300 degree pot that will work with the pc.  And how will you stop the wheel?   Youd have to mount a special heavy duty stopping system so the wheel dosnt spin all the way arround.

  To increase resolution.   You get more turn of the pot, so more degrees of control.   Its like a 300dpi   mouse -vs- a  600dpi mouse.
 
  A direct shaft mount can cause trouble.  Not just because the controll will stink (low res), but because if the pot dosnt turn far enough,  windows will not calibrate it correctly. (i tried it before)
