Default been super busy with work travel and family in town, but...

got a little progress today. Had some "surprise" work travel to NorCal right after I got back from DC area, then my mom drove into town last weekend, so it has been hectic again lately, but I did get some progress today - I worked with the machinist at my job to machine up the first of four bearing carriages to make my suspension rocker arms to move the shocks/coils inboard. We had to lathe out the center and then cut an internal groove for the spiral locks and he did an awesome job.

Now I need to see if I can make the pieces for the rocker and weld them on without distorting the hell out of the little housing. He has the bore tight to just over .001" which is way better than I could have done, but leaves me little room for overheating while welding.

It is hard to see but I have two bearings in there so they can react any moment trying to twist the arm and force it to only pivot about the bolt. He is going to make the other three housings tomorrow and then next week I hope to get in there and lathe up some 1/2" spacers for the bolt.

The nice thing will be that I can build a ratio into the rocker arm that matches the ratio at my lower A arm between the shock and wheel center - that will mean I should have a 1:1 wheel rate and therefore a 1:1 motion ratio. That is nice because I was buying really stiff springs for the 914 trying to get a good wheel rate, now whatever I want at the wheel will be exactly what the spring rate is, no motion ratio math to mess with.
