Re: [ARSCLIST] Tape baking question

Some good (and certainly responsible) points here, but I feel
compelled to say that i'm uncomfortable with the idea that there
exists somewhere a *true* sticky shed, and that only tapes "bound together
until treated" qualify. This not only delegitimizes anything less than
over-the-top obvious hydrolysis, it also implies that (1) absolutely any
and every reel of poly tape, provided it contains at least one splice,
should be frozen before playback just in case the inner splice is sticky
and (2) we all have the option of freezing reels and playing them back
in a refrigerator.

That's bananas..

Hi Brandon:

The problem is, there could well be parts of the tape pack that are stuck together (pinning and I forgot the other word Richard uses). So unrolling those parts before they are treated will destroy them (peel the oxide off). I asked Richard about this very type of reel before and if I recall the answer is freeze it and then play it cold (ie tape machine in a fridge) at very slow speed, which should unstick the bound portions enough to spool onto a reel for baking. The other parts, like 176, don't respond to baking and need the full cold treatment, if I recall. It's much more complicated that just spooling pieces off because true sticky-shed tape is probably bound together until treated and thus will be destroyed by spooling until it's treated.

Don't take what I say is gospel truth. Let Richard weigh in since he's done the research.

First of all, i mean not to steal
Richard H's thunder, as he knows quite
a bit more about this subject than me.

That said, it strikes me that the solution
proposed here only accounts for splices
*so* sticky as to be identifiable by touch alone.
Thus allowing selections exhibiting less
ridiculously obvious stages of hyrolysis
to miss the boat.

Quoting Tom Fine <tflists@xxxxxxxxxxxxxxxxxxx>:

Guys, this is not all correct. Wait for Richard Hess to chime in.
