clutch pedal binding?

Just speculating Denny,
Clearance inside throwout bearing too tight? As shaft gets warm it is expanding and reducing inside clearance to a point it is causing interference.

This makes the most sense....but I can reach it and thought it had all kinds of slop.

I'll get a helper to activate the pedal while I watch they the inspection opening from the underside.

Gotta be something that a wee bit of expansion from heat is causing the stickiness
