I am getting some tools made to do the tapers for GM tierods and the cone washers for the steering arms. What type of steel should i use for the arms?? .:confused: :confused: :confused:
They will be flat and the the bottom caps as center piece for the bearings. 1/2" mild seems to be to soft, i would think./? I was planning on useing 3/4" stock of some sort, but not sure. The tools that are being made for me are out of high speed steel. Any ideas??? I just do not want the arms to break on the road after a hard day of wheeling.:( :(

I you have to ask, should you be building this stuff?

I was just thinking the same thing.

My all pro arms are made from 4130 chromemoly.

I was thinking the 4130, but the ones that SeaBass should did not look like 4130. Just wandering????:( :( I thought he might know something everone else didn't.

Is it any more difficult to layout a couple of holes on mild steel than chromemoly? The rest is cutting and drilling, granted chomo is harder to work with than mild.

i've seen it done with 1" flat bar... with that said mine are 4130 chromolly :D

here's a suggestion-

there are a LOT of aerospace machine shops in Tuscon-

start calling about purchasing scrap or excess bar stock in the following material:

CARBON STEEL- EASIER TO MACHINE, SOFTER, CAN BE HEAT TREATED
SAE 1040
SAE 1080

ALLOY STEEL- MORE DIFFICULT TO MACHINE, CAN BE HEAT TREATED
SAE 4042
SAE 4130

STAINLESS STEEL- MORE DIFFICULT TO MACHINE, CAN BE HEAT TREATED
SAE 316

___________


IN MY OPINION-

4130, 4340 is an over kill for most applications-
and they REQUIRE heat treating to achieve good mechanical properties. Annealed 4130 and 4340 are tough, gummy steels that are difficult to machine. We prefer to machine them in the 38 to 43 RC hardness range.

Thanks Crawler#976:D :smokin:

I am making mine out of 3/4 inch flat bar. I dont think it is scary, I think it is exciting:D

If you can bend 3/4 inch flatbar in your steering setup is sure as flickity fawk aint gonna be on the road, not unless your in a massive wreck or soemthing...

As far as on the trail...sure...maybe if ya do some hardcore shit and hit somehting just right...but then does it really matter? I think not.

Im doing my whole hysteer setup and lovin it.

By the way, you dont have to have a left hand tap made realy, you just have to take the tierod off to adjust your alignment. Not a big deal considering all the mula you save if ya ask me.

Just use something better than A-36.
:D

And chromoly for the pins wouldn't be a bad idea.

mild steel is fine as long as it's going to be 3/4" or thicker.

I used Mild Steel, I used 1/2" on my Land cruiser and had no problems, I reccomend the 3/4" like in the drawings on my web site.

your tie rod will bend/break long before you mess up 3/4" steel.
