Holding onto more Axles

Continuing the “science” from last week, I’ve now seen how CA affects the performance of both a press-fit, and a keyed fit when the CA is applied before pressing the axle into the wheel. Because it would be great to be able to fine tune the quartering after assembly, I also picked up some Locktite 290, which is designed to wick into an assembled joint.

For comparison, I’ve copied similar strategies from the previous round of experiments. Compared to dry fit, CA improved the performance by 60-90%. Compared to CA fed by capillary action, Locktite 290 improved the performance of a straight interference fit by about 20%.

  1. The axle is steel, right? At least some formulations of loctite require the presence of Steel (or iron, i assume) on one (or both) of the parts to do their thing. I’m not sure if that’s true of 290.
