Re: 4" Heavy Duty Mecanum Wheels

Late reply I know:

The core of our rollers were teflon tubing. I came up with buying push nuts what would grip into the teflon and pushing them on in opposing directions so that in order for the core to come out it would have to pull both push nuts off (also those push nuts had holes between all of the teeth biting into the teflon tube, resulting in even more of a mechanical bond.

I can tell you from the experience that it takes razors, a vise, vise-grips, and some sweat to take one of those rollers apart (we had a few duds and wanted to recover the teflon cores for re-dos).

Did you continue this project?
