A rather small update today. The rear wheel has been attached, by a rigid single-sided arm. While there was going to be a double sided suspended arm, I switched to single-sided after realizing the complexity of mounting a 6 inch hub with an 8 inch tire. While I could have used spacers and a longer axle, I felt this was a simpler solution. After this change was made though, I realized that suspending the single sided arm was more complex than I had hoped, so to save myself the trouble of this, purchasing a shock, and tensioning the chain, I decided to go rigid. I hope I do not regret this decision.
Secondly, I have done away with the weak looking connections between the front axles and the ball joints. Instead, I simply welded them together, which should be stronger and which resolves my issue of kingpin inclination I had previously. The new connections give close to no scrub.
Next to come are the upper arms, which I will be working on later today. Although I am nearing completion, I am already starting to dream of my next one, which is more than slightly worrying.
