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.
|Failure weights (g)||Trial 1||Trial 2||Trial 3||Average||Comparison||Improvement|
|Interference + CA||554||287||460||434||223.5||90%|
|Key + CA||470||650||557||559||358.5||60%|
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%.
