high steering arm question

are they made of mild steel or some stronger alloy?

ive been setting up to build my own, and Im recently reading that the professionally made arms arent mild steel?

what bar stock should I ask for to machine some?

Its gonna be bear milling that balljoint recess out of nanything hard!!!???

I have some 1x2 inch titanium availble , but Id go thru $100 worth of tooling trying to shape it.

Re: high steering arm question

I am a tool & die maker/machinist by trade, and have made many steering arms, both Dana 60 & 44. I use ordinary cold roll mild steel and have had no problems with them. I would think that if you use something hard it would make it brittle and more likely to break if for some unknown reason it would come in contact with a rock or other immoveable object.

Re: high steering arm question

great! thats what I wanted to hear, I was pretty sure mild was ok, but just aking sure before I actually spend some time making some!

hey one more,
where did you get the tapereed reamer to cut the recesses for teh conical washers?

got any pictures of the arms youve made?

Im not much of a machinest, but have access to everything I need, and plenty of machinest pals to help out ( hopefully do most of it for BEER)

Ive found a taper for the rod ends, I just cant seem to locate the 30 or was it 32 degree taper fort teh conical washers.

Re: high steering arm question

Try http://www.useenco.com for the reamers. They have lots of tooling for machine shops.

Re: high steering arm question

I am not using the conical washers. On the 44 arms that I have done I have drilled and reamed seperate hole for 3/8 dowel pins. This takes all of the side to side locating pressure off of the screws and puts it on these dowels which are designed for that purpose. The conical washers are easier (cheaper) to install on the assembly line, but in my opinion the dowels work better. As for the taper for the tie rod ends I have found that for me it is just as easy to make an insert on the CNC lathe and TIG weld it into the arm, as some of the guys that I have made arms for prefer Heim Joints over tie rod ends. I have some AutoCad14 files of the hole pattern that I use for the dowel that I might be able to send you if you have acess to AutoCad14. I may be able to send it as an .bmp also.

Re: high steering arm question

If you are looking for a 30 degree per side "tapered reamer" look under countersinks. I believe a 60 degree countersink is the same as a 30 degree per side "tapered reamer".

Re: high steering arm question

Id like to see the file in BMP foramt if possible.

Im very GREEN at this machining thing, but TIG, welding, By God is something I can actually do!
beleive it or not, I get PAID to do it.

IM open for ideas, no Heim joints for me, all 7/8 shanked rod ends. and Ill either do the dowells or conical washers its dependant on which I can do easier ( probably dowels)

Re: high steering arm question

Btw, just to clarify, you're not going to find much on the Enco site, you have to get their main catalog. In that they have a ton of stuff.
