minimum steering lock on a roadster

Gday guys

Thanks to the fellas who helped with my last post about steering arm clearance. Now I dont seem to have enough lock side to side. Im a newcomer to car building - what is the required range of motion lock to lock for your wheel. When youre going straight ahead the wheel's at 90 deg to the front c'member - on full lock what should it be? 45deg?

Probably a dumb question but hey I'll have a shed load more as the build continues...

DO you mean how far the the wheels turn before they hit the kingpin retainer bolt/stops?
Or how many turns lock to lock, or how far the pitnam arm moves?

 

Tell us a little more about your setup.
I beam? Dropped? Cut bones, hairpins or 4bars? what steering box? Etc...
What is limiting the lock.
The range of the box? or does the tire rub on the cut bones ( or hairpins, etc...).
Or does the spindle hit the stop.
Also when you look at the outside tire at full lock and it does not look like there is a lot of degs of steering, it might look worse than it is due to the Ackerman effect...

 

Im also wondering if ill have enough lock,using a vw bus box,side steer.the steering stops are about 1/2 to 3/4 " away from the spindles at full lock(46 axle and spindles)..the box is the limiting factor.sorry to hijack.

 

I really need to post a pic but I have a stock I beam and the bolt on steering arms knock on the axle on full lock. What is used as a bump stop? Anyone have a pic?
My mates at the rod shop say Ive got enough lock but my inspecting engineer says not enough.

Steve, this may sound dumb but measure up the total steering angle lock to lock on a stocker car, honda or some other, and if you have as much steering lock as one of them things you have some ammunition to go shoot down the inspector. He should be able to give you a figure (an angle in degrees) that the rules state. Not just some off-the-top-of-his-head figure.

Sounds like you guys have it pretty tough over there inspection wise. I'm pretty damn sure the UK is going to go that way in the next few years.

 

The spindles should hit the stops. You can shorten the arm on the spindle or lengthen the arm on the steering box to increase the throw. Hope this helps.

 

I mounted a '36 axle level in the vice (kingpins horizontal). I ***embled a spindle, kingpin, lock bolt, and stop nut to the axle. The spindle turned 40 degrees before it hit the stop nut. This means the front wheels turn 40 degrees each way from straight ahead.

Hope this helps.

 

Thanks for the advice guys - Ive bought some ****on head allen key bolts for the spinles instead of the standard ones and they allow more lock - just a bit of radiusing on the axle with a file and i should have 45 deg which I think will be enough.
