Anyone need cast spindles sectioned???

I can really appreciate where all of you are coming from with your concerns, but it sounds to me that the spindles will hold up just fine. I have modified cast steel spindles for off road trucks and didn't go through half of what HarryBalls is for these and I have never had one come apart. One guy was running from the cops and hung a wheel up on a palm tree stump and spun the truck around only to bend the spindle nowhere near the welded joint.

I have just done some research on this very subject because chances are that I won't be building a 100% custom spindle for the Taco. Modifying the stock one will be more than adequate (and cheaper for you guys.) I have spoken to two different engineers and both of then told me to do just what HarryBalls is doing. As long as the part is heated to about 400 deg, welded, then allowed to cool slowly, there should be no concern.

I have just been through the ringer with a bunch of guys that felt that EVERY 4130 weldment needs to be stress relieved. When, in fact, very few people do. We can argue about this for a long time. So let's weld one up and beat the living shit out of it and see if it brakes. I am going to do some "stress analysis" on my Taco spindles before there called done, but I already know the answer.

You drive lowered vehicles, you will all slow down for a dip. The stresses the part will see is quite minimal. I would be WAY more concerned about stress risers then proper welding technique.

MAX-
Got pics of the guy that hit the palm tree stump... i want to see some auto carnage... lol

THANK YOU PHIL AND THANK YOU MAX!!

There was almost no damage. He drove it 30 miles to have me fix it. Only a bent steering arm on the spindle and the tierod was bent from hitting the stump.

lol, dayum it, I was picturing the bottem ripped out from under it. haha,

NP harry.

LOL like i said nevermind. Everyone is acting like they know exactly how they are done and Danny thats not all we did. If you actually saw them you wouldnt talk like that. I guess this is just the wrong stuff to talk about on this know it all website.

all im saying is i have seen them break, why do you think they are a 1 piece deal, if they were able to be welded on the factory would have welded something on them, go ahead and sell them to someone and when it breaks and kills them you would have wished you lisened to these know it alls

Exactly. I'm a mechanical engineer and stress risers are way more of a problem than how you would weld it. Though welding is a critical process, and I don't want to take away from that, the stress risers created by something as small as the lack of a proper fillet could cause the part to fail. The easiest thing to do would be to create a fairly accurate solid model in Pro E and do an analysis on it that way. Find someone who works in a truck body shop (like dump trucks, triaxles, or coal buckets) or something similar. They are pretty good at that type of thing and might do it on their lunch break for a couple of bucks.

well you see Harryballs you have to take in the consideration of quantom physics and spindle-weldology which states that N+R to the third power = Everyone on streetsource is a genius and the best engineers on the planet... Sounds like you know what you're doing - if i had a honda i'd have you section mine.

80 percent of the people on streetsource have no clue on how to do things and will just talk what they heard there mothers brothers cousin say. gotta take all the info you get from this site with a grain of salt cause of all the know it all idiots on this site that are clueless in reality. if max says it good you can bet it good, and i think 325 is a hell of a good price to pay for something done right. the people that complain and get things done for 1/3 of the price are usually the same people bitching on here a month later how they got beat or how there shit broke!!!!!!!

hahahaha i think its more like 95% and the few that do ask for help on stuff end up gettin a whole bunch of wrong advice from the know it all idiots .....
