I’ve had the Suckit Dust Boot for a while, and I’ve had a nagging problem with it. The left “ear” was always very sticky–it made using it and adjusting it difficult enough that I tended to avoid using it. My initial attempt to fix this was the time-honored tradition of ignoring it and hoping it would go away.
This weekend I resolved to fix it or send a strongly worded letter to the people at Suckit Dust Boots and demand satisfaction. I assumed there must have been some sawdust or other debris interfering. Took it apart… nothing. Tried a little lubricant, no improvement. After taking it apart and putting it back together at least a dozen times, it occurred to me that the red slider piece might be running sliding against the the piece of the Z-axis that is right behind it. Took out my sander and literally just touched the sander to the back of the red slider for about 5 seconds, re-assembled, and now it slides up and down with ease.
I only had to live with problem for months–probably a year and a half? Before getting down and figuring it out.
