Well bevins, you're in for a treat - I started on the front suspension a little while back. I've been spending some time after work on a lathe in my building making some spacers and such to make it work, but I've managed to get a working solution, I think.
The details of how the design came about are in
this thread, but basically the lower ball joint is attached to the spindle from the underside now, instead of from the top down, using a taper reversing spacer I made. The upper pivot is a rod end (heim joint) attached to a 4" long spacer which fits into the upper ball joint mount on the spindle with the original camber adjuster removed. The lower ball joint is a K6527, which I think is off a grand am. It has a 2"/foot taper, or about 10 degrees.
I've started fabricating the lower A-arms. They are similar to one I saw posted on the forum before - haynes roadster maybe? Anyway, I haven't decided if this is the design I'm going to go with, or more of a book style one with the plate on top of the tubes. I'm not real happy with the welding on this one either - I'm just learning to arc weld. Almost all of the welding on my chassis was oxy-acetelyne, which is great for thin stuff but gets a bit tedious on thicker metal, I find. Also, refilling my little tanks is getting expensive. The arc welding is a crappy 115v unit (70 max) from Canadian Tire, which I borrowed from a friend. I've been thinking about getting one of the chinese made 3-in-1 (tig/arc/plasma cutter) units I see on ebay and amazon, but I've been hesitating because I'm not sure about the quality, and because I don't have 220V in my garage right now.
