Ben,

Unless you order the Adapt-A-Trays you will be unhappy with the American 
Harvest for 7-inch reels. You can modify one tray yourself by cutting 
out the mesh, leaving a ring if you don't want to wait.

The Excalibur seems to take reels flat without the centre column of the 
American Harvest, so it might be better. I own three American Harvest 
units (and did a 114-tape project baking each tape but one for 48 hours 
and the last tape for 4 x 48 hours). Start with 8 hours.

Normal baking temperature is 50-54 C (122-129.2 F). Many people round 
that off to 130 F.

Cheers,

Richard

Many of us receiving tapes that had been stored "in the wild" vs. "in captivity" see baking times of 24 hours as common. It surprised the good folks at the archive when it came up in our discussion.

>> In my opinion, one of the worst things you can do to a reel that should have been baked is unspool it prior to baking. This creates problems for reels that have acetate tapes inside a layer of need-to-be-baked tape and there is no good solution for it. Fortunately, you may be lucky unwinding the tape that needs baking as the acetate tape is closer to the centre of the reel and the outer wraps did not have the higher pressures that the inner wraps would.
