For my meth monster project, i need to make a modification to a pair of EJ-HD steering arms. The machining involves milling down one of the mounting pads on each arm (about a 4mm cut) so that the resultant mounting pad is only 1mm tall (i.e. do not mill the pad down below the surface of the arm itself). The milling needs to be done pretty parallel to the other mounting pad (+/- ten thou), so not a candidate for me to grind or file back myself.

The area that needs to be milled is in the purple boxes in the images below.


I had hoped that Duncan Foster could do it for me locally, but they do not do general machining. The machinist they use for this type of work has been ill for the last 3 months.

Can anyone on the forum undertake this machining for me, or reccomend someone who can? Happy to pay for both postage and time.

Cheers,
Harv

Hi Harv,

I have a friend in Brookvale that could do this for you, I will ask him when he returns from Bathurst V8's (racing a TCM car).

I'm not sure how his time is but I could do it for you as he lets me use his machines for this type of work.

Actually I have to get some spacers machined up for my diff, so I will PM you when this is going to happen, kill 2 birds with the one stone ?

Wally I have a small machine shop and could jig something up on the mill if you get stuck

Ahh shit I’m going cross eyed

Harv I could machine that if you get stuck.

Many thanks. I think Greg has got me sorted.

Thought I would post some fun I had last week doing the machining for Harv's steering arms. (Hope you don't mind Harv ?)

Firstly let me say the material the arms are made from is super tough, forged material. So hard in fact I could only take .2mm each cut and I was using the best American supplied cutting tool !

I scratched my head a bit on how the factory machining was done in relation to holding the arms and the only way I could do it was in a vice and with a parallel cutting tool. I took exactly 4mm off the face and manged to get the pads dead flat to each other.
This is a job that cant be done at home although after thinking about it I should have ground the majority of material off first then finished it off with the mill, it may have been a little quicker.

Regards Greg

Nice work Greg

Neat result!

Thanks guys,

I love this sort of stuff and it helps when your lucky enough to have access to good machinery.
