anglia4 Posted August 19, 2014 Share Posted August 19, 2014 What about doing a solid front axle beam with trailing arms and a panhard bar? You'd just have to do something clever with the steering column, like put the bottom end of it on the front axle beam with a telescoping steering column with universals. This at least works in my head while I'm in an Irish pub eating my dinner posting from my phone Quote Link to comment Share on other sites More sharing options...
Guypie Posted August 19, 2014 Share Posted August 19, 2014 would something like this work? 1 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 19, 2014 Author Share Posted August 19, 2014 Possibly, but I'm thinking a beam style front axle might be the only way to go, I can still use the the struts I've got anyway for ease Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted August 19, 2014 Share Posted August 19, 2014 Ill try explain it without pictures. It depends on your steering setup. Ours used a Gokart style setup. So steering column has a tag hanging off it which then has the 2 tierods out to the steering arms. Then we had independent A-arms mounted on the side of the chassis. Now imagine the radius the arms go through under travel. Then the radius the tie rods go through under travel. They are wildly different due to one pivoting from the centre of chassis and being much longer. So even the slightest suspension travel meant HUGE toe changes. Im sure there is a picture that shows what i mean. This works because the pivot points for the arms is central. My knowledge is all from quick googles i had to do during the rushed build i did. Im sure with more time you can nut it all out and build something lush Got any info on that kart? Quote Link to comment Share on other sites More sharing options...
Steelies Posted August 19, 2014 Share Posted August 19, 2014 i'd go for copying your favourite t-bucket front end and basic gokart steering, kinda like guypie's posted but minus idlers and plus correct steering direction! Quote Link to comment Share on other sites More sharing options...
Truenotch Posted August 20, 2014 Share Posted August 20, 2014 plus correct steering direction! Hah, that's awesome. Reverse steer FTW.  This one is basically the same idea: Quote Link to comment Share on other sites More sharing options...
CUL8R Posted August 20, 2014 Share Posted August 20, 2014 If you go Solid front axle, you could effectively make a smaller version of what Im doing.  Mount the steering box up front, one arm from the drop arm to one side hub, with another arm joining both hub.  Otherwise, you could cut down a steering box, mount it up by the dash - ie steering wheel is pretty much on the input shaft. Output shaft has a drop arm that runs from the cockpit down the side of the car to the top of the front hub on whichever side you need, with another arm joining the two hubs.  You can see the drop arm to the right of the Overflow bottle/firewall. With the arm itself travelling down the car to the front hub to push or pull in the direction to give the steering change.  Panhard centralises the lot.   This one, they should've mounted on the opposite side, so lols they have had to make a reverser to make it work..  Quote Link to comment Share on other sites More sharing options...
CUL8R Posted August 20, 2014 Share Posted August 20, 2014 Anything off like a small datsun (maybe even your Corona) would be quite small, and if you're cramped for leg space, this isnt a bad idea to get the steering completely away from the feet..  This is taken looking from the front, however, gives you a basic idea of the front beam of a randoms car.  You can mount the arms however you like, however, mounts on the same plane are the trailing arms, and the single top mount is used to control the castor (combined with whatever you have built into the axle king pin mounts) Panhard mount is 2/3s the way along.  Datsun Steering boxs - check out how tiny they are! Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 20, 2014 Author Share Posted August 20, 2014 all extremely good info! starting to paint a picture for how i went wrong and options from here on out. that datsun steering box is tiny! i wonder if i could track one down,  also, so not keen to build a stock car! this project had given me such an appreciation for things that are scratch built. just so many little details that need to be worked out.

CUL8R Posted August 20, 2014 Share Posted August 20, 2014 It'd be easier for me to draw it in person, but laptop doesn't exactly help MS paint skills lol.. Â Can put you onto a guy for high quality rod ends - to make the trailing arms - can do mild steel ones. Dont really need the Chromoly like I have lol Quote Link to comment Share on other sites More sharing options...
Guypie Posted August 20, 2014 Share Posted August 20, 2014 Hah, that's awesome. Reverse steer FTW.  This one is basically the same idea: Yeah this is what I meant, thats what happens when you post just before going to sleep! Though reverse steering could be a fun brain exersize... 1 Quote Link to comment Share on other sites More sharing options...
Rookie Posted August 21, 2014 Share Posted August 21, 2014 Man, I totally vote for shitty geometry so that it is max lols to drive. You aren't going to be trying to win anything so just make it work and have a lol every time is swerves wildly when you hit a pot hole hahaha. 1 Quote Link to comment Share on other sites More sharing options...
Rookie Posted August 21, 2014 Share Posted August 21, 2014 But if you are concerned then this is how I would do it for convenience. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 21, 2014 Author Share Posted August 21, 2014 I do like that design, it won't fix it completely, but it will lessen the effects, and I won't have to waste any of the parts I've made already. It's gonna be a few weeks till I can work on it again with Hanmer and the Corona being delivered the weekend after that. Gives a good amount of time to sus it all out Quote Link to comment Share on other sites More sharing options...

BlownCorona Posted August 21, 2014 Author Share Posted August 21, 2014 Since I only have one wish bone, the camber will still change, and cause the toe to change, but since the pivot points are the same, it will only change the toe but the amount the a arm moves around its arc of travel, which will be fuck all Quote Link to comment Share on other sites More sharing options...
Rookie Posted August 21, 2014 Share Posted August 21, 2014 If you make the little extra arm the same height as the difference between the axle centre line and the steering arm centerline on the upright you won't have any toe change. 1 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 21, 2014 Author Share Posted August 21, 2014 Seems like a sound plan Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted August 25, 2014 Share Posted August 25, 2014 This is an awesome thread. Some good head banging design input shit going on. Take a team associated rc10 and just scale it up. Then sit in it and drive. 2 Quote Link to comment Share on other sites More sharing options...

Nothing wrong with a little toe Quote Link to comment Share on other sites More sharing options...
