Fixing a sticky Happ trackball
I’ve experienced a couple of Happ trackballs recently that seemed to get stuck in one direction. Though with a little roll back and forth it would continue on it’s way. Very frustrating when trying to kill millipedes!
These trackballs were brand new, though because they had been sat on the shelf for 9 months, the grease and anti-rust agents must have solidified a little. So, I have written a set of instructions on how to overcome this problem. Saying that, it’s not limited to new trackballs experiencing a rolling problem, but you might be able to revive your old Happ trackball that has seen better days rather than replacing the bearings. Well, worth a shot before replacing the 6 sets of bearings anyway.
