While trying to get this to tick, I realized my probelm was that my 4mm rods came it at 3.98mm however the inner diameter of the bearings were 4.15mm. This is causing why wheel to slip along the rod bumping into the raised fork bearing support on the tourbillon cage. Any suggestions or is getting new bearings my best bet? I also thought about gluing the rod directly to the internal bearing..... I measured all of the bearings I have and they all are 4.15-4.16mm. The 4mm rods were right on spec.
