That progressing but did you ever see my diagram for how I make my straight axles? If not, its in my Fiat and Walt's Puffer threads. If you need explanations of anything, just let me know. Be thrilled to see you make one of these. Its really not that tough, just has many working parts and time consuming. Let me know if you want me to post it here. Also, I don't use flat aluminum to make my knuckles, I use rectangular tubing cut to shape. Much stronger and a bit thicker.
