The Wishbone project

[Beezil]

Here's some various pics.......



this is an older "imaginary version" the links are MUCH higher now...



the link layout, including the wishbone and original joint idea



the rest of these are detail pictures of the joint, which the success of the design decides wether I wheel for an hour in moab and get laughed at (that will happen anyway) while hinkley welds my shit for corona, or I keep ridin' and see what happens next....

I like the string, are you going to do a write up on that mod.

[Dazz]

Where did you purchase the joints?

[Beezil]

I made them

[BrettM]

I like the tapered bearings and all, but why not just use a Johnny Joint or a 1.25" rod end mounted with the bolt verticle?

are you doing anything majorly different than Wanderingwillys (thats what he goes by on PBB, forget what he goes by here...), are you planning on hydro-assist (or full hydro), I remember wanderingwillys saying he needed it with his.

[BrettM]

oh baby! I just noticed the Krawlers!! nice

[PNWXJ]

Beez..I like it looks great! I too like the tapered bearing joint you made I am wanting to build one like that for my rear bumper/tire carrier pivot.

Using a JJ as the single pivot point from what I have heard is just not strong enough for this. There are alot of varied forces on this joint that the JJ or a heim cannot handle in one.

One ton can probably comment on the rod end survival expectancy....as for the johhny, they are not designed to control energy in t he plane that I need them to.....when positioned int eh plane that they ARE designed to work in, they do not offer enough articulation for this design....

as for wandering willys, I'm not sure what he is running........however, he might be the guy that one ton was talking about during a conversation about wishobone joints....he mentioned someone modifying a trailer hub or something like that....if wandering willys is that guy, than yes, this joint idea was directly inspired by his hub idea, so....my hats off to the man.

[BrettM]

wasn't it wanderingwillys that had a 3/4" rod end break and then he replaced it with the hub thingy? I don't think you would be breaking a 1.25" rodend, those things are about as big as your hand! I saw one used on a front upper wishbone on a heavy buggy with a big-block ramjet whatever and that monster rod-end just laughed at it.

[BrettM]

how many degrees of misallignment do JJs allow? for the big 3" Currie ones?

[Beezil]

I have no idea.......

look at this this way:

it didn't take me long to spin tat stock on my lathe, and the damn thing has 360 degrees worth of articulation!

dig that!

I realize that some of the things I end up with are not always the most direct, time-saving, or logical!

First off OT needs to learn what size rod end to use, 3/4" is not the correct one, as he found out.

Yes, this is out of pure experience, the JJ from Currie can survive, even comp type abuse, on a side load. ie using it on a trianglated 3 link arm. (Yes I said three link, wishbone if you want)
However, I wouldn't put it on a daily driver with a side load, but then neither would I do a tri-3 link/wishbone on a daily driver. Yes Beezil I know you're not building a DD I just wanted to be clear about the conditions on which I would push/use a particular set up.

Beezil,

Nice joint, but a question for you... How are you going to keep the dirt and sand out of the bearings?

Beezil,

Looking back at those pictures I did notice that axle is WWWWAAAYYYYY to nice looking to be under your rig... So another question who's rig is that?


hinkley

[Beezil]

the two washers have around .005 clearance between the joint. I know that is enough to let moab silt in, but eveone knows, once you mix moab silt with water, you get a high-quality, natural, clay-based grease!

perhaps adding a zerk will help force out the other junk.....

[Beezil]

WWWWAAAYYYYY to nice looking

you didn't perhaps, find evidence of welding did you?

I promise markie mark, I will remember to weld ***all*** my brackets on this year
