The old stubborn plastic rollers can be brought back to life with.....
...of all things...a soldering iron!
I know you're thinking..."come on!..no way"...
Yes, way...this worked for me.
Put your roller bracket in a vise so the roller is laying flat and is facing up.
Try to turn it...really doesn't want to turn? You've tried WD40, etc, etc...
Nothing seems to work?...it's like the plastic is too tight on the stem.
Well, you're right it is.
Plug in a good soldering iron and hold it against the underside of the stud that the roller turns on.
Give it time to heat up, if it doesn't-get a bigger iron.
If you heat the stud till the plastic melts (JUST A LITTLE), it relaxes the tension....
and like magic, the roller will turn with ease.
Keep turning it while it cools down, then spray some dry graphite or lithium grease in there.
Your roller will be good as new.
I guess I should have made a video....
