Calling Beezil

[csudman]

Love the wishbone. I'm three linked right know but it drives like ass. Hows it workin. On and offroad?

Couple of ques.

1. Local bearing shop said they can get me a 2" sealed needle bearing rated at like 30000 lbs. Think this is heavy enough?

2. Is full hydro the only way to go? Would hydro assist work?

3. No track bar. I understand that. Is the wishbone stong enough on its own to hold the axle centered? If not, what about tieing the two upper ends together with a solid bar?

4. If i go this route would you let me copy your genius w/ some modifications? I.E. give me your dimensions and I'll change them to suit.

5. Approximatly how much lift do you have? I think your running 37's. I'm thinkin 38's or 40's havent decided. ( Don't worry I'm gonna biuld an exo tied into the a and b pillers and sleeve the frame.

More to come.

The reason this is in tech instead of sending a PM is so I can get others input also.

Thanks.

I can't tell you enough how well that wishbone worked without sounding like a braggin' jag-load.

it really does work better than I thought it would.

I have only s-l-i-g-h-t rubbing on the pinion at full stuff, nothing to be worried about at all.

otherwise, there are no clearance issues, and absolutly ZERO side-to-side flex......i mean NONE.

one ton is also running the wishbone, had some minor clearance issues that are probably fixable....

maybe he'll answer on this thread, i dunno.

while I love mine, he may hate his.....

Specs for the wish bone?
I assume that this is achieved with a progressive arch. Theres probably a better name than that but thats what I'm callen it. Whats the width and overall length? What size tires you runnin? Will this work with hydo assist? instead of full hydro? And are you guys gonna be gracious enough to help a fellow out. Got a shop and a buddy how used to build race car links. So this is defenitly doable. The other big question that is only a temperary one until i buy another vehicle. Streetability? Good or not. Thanks

try this thread if you haven't seen it already

http://www.naxja.org/forum/showthre...97&perpage=20&highlight=wishbone&pagenumber=1

the wishbone arms were made with a cnc tube roller/bender.

not many roller benders are capable of doing progressive bending, it will probably be challenging to outsource, unless you planned to do a manual step-bend with a bender, or multi-pass with a non-cnc roller as a one-off.

I *may* make the set of arms available as a DIY thingy if there is any interest.

the arms are .250 wall 1 3/4" diameter DOM

 

[csudman]

I was planing on the old heat and bend by hand method. Trial and error. I guess the only thing I really need is the lenght and width measurments and I can go from there. If I can't get it right myself. I live in Statesville, NC Race city usa. Theres about 20 nascar shops within 20 miles of me.

CJ, do you know where McCombs Steel is? Its near South Iredell HS. Everytime I need material, I go over there with a tape and dig through the scraps and get what I need. They usually charge me anywhere from $10 - $20 for scraps. They've got a whole wall that's a scrap shelf so there's plenty for the picking.

Good luck!

thats not gonna work my man.

if you want soemthing formed, pm me when you are ready.

I thought it was 1.5". Whatever it is, it's plenty stout. My frontend feels stable again with the new wishbone design. I need to move my axle mount up appx. .5" and I won't have my interference issues.

Good luck on the heat and bend of this size material. We're not working on motorcycles here.

hmmmm, I think yer right one-tube......it was 1.5 right?

Thats my source for stuff to. I've got like 30 bucks.

just caught this.....

if you are trying to do the bearing-joint design, you CANNOT use needle bearings unless you are also using seperate thrust bearings!

you have two heavy forces at play:

Radial and Thrust.

caged needle bearings are for radial forces.

if you decide to build a similar bearing-joint, use tapered roller bearings (timken style).

my bearing-joint was definitly the most complicated (unnecessary) approach.

One ton simply used a HUGE heim joint, and it is definitly trail-tested.

I'll talk you out of trying to do the bearing joint any day, unless you happen to own your own lathe and have access to hunks 4140 shaft material.....

 

[csudman]

I do have a lathe and can probably get the material. I've talked to a few people and cannot get the bends I think I'll need. I talked to a guy at Carolina Rock Shop and he was against running it on the road with out a track bar. I figure it it breaks it doesn't really matter. I'll have no castor control anyway. Well, the big ques. How much to bend the material. I can do the rest. I think 5.00 is probably reasonalbe.
