I am looking for an engineering company/ individual to put splines on some thick wall tubing for my planned Torsion bar project, I can fabricate the parts myself , but the broaching of very small quantity is not available locally.The torsion bars I am looking at are Peugeot and( on the standard car )they go into what seems to be cast steel so cutting out and machining parts of the Peugeot rear arms is a no no.

We use a place, Stoners, in Clevedon, but it's a long ways from you Tom! They do standard broached stuff for our valve work, but don't know if they can do internal splining.

If the Peugeot rear arms are cast steel, why can't you cut the required pieces out and mount them to your whatever?

If you have access to a lathe and some changewheels you could broach the splines yourself. This video is of cutting a gear, but the process is the same for internal or external splines.

I have done all sorts of machining on a lathe, but never tried broaching like that, mainly because I have never thought about it, I have used Minutemans to cut internal keyways, which I suppose is the same process but made easy. as I have been sitting here typing I have thought of a job that I can/might be able to do, :)
