My 4 Link buildup

All I can tell you is that thing isn't going to generate lift, and will produce more drag than Shawn. :D:D
Bahahahaha!!! :rofl: Nice.

Brett, my opinion has not changed since I built my four link, so yes, I think you know my prediction. As far as enginerds go... Those guys can be right some times, and it sucks. Brett used his fancypants equations to tell me I was going to be capable of bending my ridiculously overbuilt lower control arms. Guess what? I've got a bent one right now. Lousy enginerds...

Why 10"? (meaning, how did you arrive at 10", vs 8" or 12"?)


Because 10" is 25% of 40"...

When building a 4 Link the general guidlines are to have 25% of the tire size as the Verticle Seperation measurement, at the axle. I'm planning on 40" tires, so 10" of Verticle Sep!

Nice one. Is anyone an engineer? You tell me.

You all are, actually, to some degree. Pretty impressive ones too. :)

rant mode on:

:rofl: Ouch. WTF. Not really sure why some of you are mocking me or anyone else that has studied and passed the science behind this stuff, especially when this is the stuff that got us through all the hell. :confused:

I'm guessing that in 3 years when Kurt gets done with his hell that he'll no longer be allowed an opinion. Then, after 4 years of proving his poop to senior engineers to get licensed, he really won't know anything. I suppose that I should throw away the chassis engineering book that he gave me, also written by an engineer, cuz the guy in there must not have a clue. :rolleyes:

The stuff you guys build is pretty impressive, and I learn a lot, even though I know it is unlikely that you are using Euler bending equations for the UCA's and LCA's, stress/bending calcs of any kind for the structural members, etc. Do I ram that down your throat? Nope. Do you need them? Maybe, maybe not. How would you know? :eek:

Sorry I ever offered my services, and that it frightened or offended any of you, especially when I considered you friends. Folks like Carl and Braden have known me for a while and know that I don't throw it out there as an ego trip, sorry if it was seen that way. I'm not here to be a know-it-all god, cuz I'm not. I don't pretend to be anything I'm not, but I am what I am, just like you all are whatever you are...and I don't recall mocking any of you because of it. :rolleyes:

Brett (talk about moving on...)

rant mode off

PS: Greg's 4 link - you're doing pretty good so far.
I'm not calling you arrogant or anything, but I know of at least 5 Engineers on this board. I am sure there are many more. Why do you think I am mocking you? I don't think I have ever met you. As far as bending calcs and other stress equations, I use a program in Excel that was posted on PBB, known as "the 4 link calcualtor", but I haven't ran any numbers in that for Greg's application BECAUSE I HAVEN'T EVEN SEEN HIS TRUCK.

Hey Brett, Brent, Big Muscle guy, Chill. Have you and I ever talked? You want me to mock you, just ask, but I'll need you to answer some questions first. Oh yeah, I'm just a stupid truckdriver, keep that in mind. ;)

:D :rofl: :D Ya, maybe so. Goes a little deeper, and Shawn & his approved Hickey touched a nerve, maybe on purpose, maybe not.
What did Shawn say that relates to what I said concerning engineers? Or are you just grouping us together because we are intardnet buddies? That's a little unfair to Shawn, don't you think? As far as "Shawn Approved Hickey", It's an inside joke, and you are using it in the wrong context. Please refrain, if you don't understand. Now, I'm cool with you, if you are cool with me, but to jump in here and get a upset cuz I made a remark about engineers, you are just being to sensitive. Maybe they should have offered a sensitivity course in your hell.

Mavrick is just pissed because I wouldn't make him some blue prints of the trailer, nor would I share our design with him 3 days before the project. We did not need someone telling us that we need to change anything after all the materials were picked up. Besides, the design changed a little here and there once we started building it.


Now, Move On!!!


So people just don't know when to say when :rolleyes:

Cuz Shawn was. If not me personally, my mistake. You must have been mocking the other 4 and not me. Engineers in general, I'm used to it, but get tired of it. I wasn't going anywhere with the "approved Hickey"...it just said "Shawn approved" so I used it, like Mark or Jim or Bob. (vs an approved hickey)

About to ask where to find these general guidelines...don't follow too many 4-link discussions cuz I don't wanna feel compelled to jump in...some that I've seen scare the livin' poop outta me, others are just damn impressive. Are there general guidelines that relate the length and radius of the arms to the separation distance, or even to each other with the understanding that the 25% rule will be followed? How about bolt and rod end size?

Oh, VERY cool...are these the "general guidelines"? clicking over there now, forgot password, waiting, waiting...will have to scrutinize later.

Oh, and Shawn, you still don't get what I was asking, bummer. btw, I've talked with Bubba before about his designs...and he gets it.

You tell me to move on...I'd moved on after our PM, wasn't negative in the service project "love and hate" thread...and then saw with your comments here that you hadn't. Bummer. Sorry man, I guess we just see it differently.

(15 minutes later) Dammit, still waiting for my pbb password...gonna hafta look later, got work to do. Looking forward to checking it out.

Brett (chillin' the most - anyone catch Kid Rock with Kenny Chesney?)

nice, that only took 20 minutes to get the pbb reset, now gotta wait 20 for my new password...(40 minutes later) dammit, not gonna happen soon, gotta hit send and look at it later. Thread's probably over by now.

I think the 25% guideline came from the Peterson's 4WOR article on linked suspensions...they spouted a lot of very generic, but safe guidelines similar to that.

I have the Excel spreadsheet here if you want me to mail it over to ya. I think there is a version 2 out there now, but what I have will give you the idea--someone went to a lot of work to make it, and it's pretty cool.

Makes trailers in Ogden, pretty cool guy, donated the axles to the fine trailer that was built.

Brent, er, Brett ( in recovery)

On its way. In fact, you're probably already playing with it. :)

nope, went to eat, and webmail is damn slow these days...just barely got my new password for pbb. Super neato T1 isn't all that cool either, when the whole building is using it.

wait, got it

HOLY LIVING CALCS, BATMAN!!!

Someone has done their homework. Very nice. Gonna have to dissect this puppy...and then really play with it. Wow.

Thanks for sending it, and thanks to Hickey for the heads up on it. Oh, ok, and thanks to Shawn for gettin' my goat. Thanks to Supergpr for calling me Brent. Thanks to Greg for starting the thread, and for the board, Thanks to Herzog for...<music cuts in, ladies escort me off stage>

Oh come on, share with the rest of the class! Especially if it's beneficial info!
