Today, I tried to remove the SlikStik Skirted knob from the Oscar Up/Down spinner. It wouldn't budge. This seemed strange to me, as it slid on fairly easily.
After a lot of pulling and some WD-40, I finally got the knob off. :-[
Why had it stuck? After looking closely at the DOT shaft, I noticed that the set screws had "dimpled" the shaft where they had contacted it. I hadn't set them that hard (I thought!), but they had apparently put small bumps into the shaft where they contacted it.
These "dimples" (holes + a ridge around the hole) thickened the shaft at those points, locking the knob onto the shaft.
This shouldn't be a problem when you've put the final knob on an installed DOT spinner, but it was a problem with all the knob-swapping I plan on doing. I sanded down the dimples, but I'm going to have to watch the set screws with future knobs.

What kind of set screws are used on Christian's knobs? The end-style, I mean. Cup, Cone, Flat, etc?
Some set screw types, like cones, will do this because they are intended for permanent setting and not for swapping out parts.

Oh yeah... :-X
It was on so hard I had to put on gloves to hold the DOT encoder wheel while I struggled to slide the SlikStik knob off. For a few minutes I was convinced I would never get the *$&! knob off.
Then I completely removed the set screws, squirted in some WD40, and things began to budge...
Thank the maker of WD40!

Kevin,
We did our homework (as I am sure Kelsey has also done) before sending out our spinners. This could only happen because on one thing, low quality shafts *no pun intended* in the testing phase of manufacturing the Tornado spinner we had purchased some shafts that had the same result, the out come was the shafts were not case hardened steel, which in turn causes a
