The reel was rewound using custom bypass rollers I had Terry at Terry's Rubber Rollers
( http://www.terrysrubberrollers.com/ ) lathe for me.
The machine is a BR-20T with the torque re-adjusted for minimal back tension.
Since this machine has idler arms with rollers, the entire fast rewind was via rollers.

|PEM 468 with no baking
This is the Agfa PEM 468 which shows significant wear. The majority of the reel was this tape, which transferred easily with no baking. Typical dusty shed (slight due to the wear of the tape).
|Ampex 456 - Pre-bake
This is from the head of the section, right after the leader.
|Ampex 456 - Post-bake
This is the same section of Ampex 456 after a 3 hour bake at 54C.
||POST 4 HOUR BAKE
|This is section 1 which was at the very tail of the tape|
|This is the next section, which shows less discoloration|
|This is from about 1 minute
into the tape where it was stopped after playing at the playback head
As the tape progressed less debris accumulated to the point that the middle of the tape showed no signs of this and played well.
