We had this conversation on a facebook group this morning as well. He also stated that the turnbuckle was maxed all the way out and brakes were worn down to nothing. I suggested that the issue could be his pedal is not being depressed all the way due to the turnbuckle being maxed. Perhaps relining the brakes and backing off the buckle would help get more push out of the pedal to fully disengage the clutch plates.
The reason i suggested this is because of personal experience, i was having the same issue during my restoration, and found that the clutch pedal was not being allowed to go all the way down. Hope this helps
