Default Baking open-reel tapes: hub question

Some kind members of this group explained to me that my open-reel tapes
suffered from 'sticky shed' syndrome and gave me links to sites that
explained how to bake tapes. However, most of my tapes are on plastic
hubs, which presumably would melt during baking. Can anyone suggest a
solution to this problem, or point me to someone who would sell me or
lend me some metal hubs that I could use?

thanks in advance.

Most 10 1/2" NAB reels were metal, but does your machine use them? At one
time they were being chucked out in their thousands. Now you'd probably
have to buy one and they're not cheap.

Are you sure you truly have oxide shedding? I've got tapes more than 40
years old that are ok. Although all my tapes are of European manufacture.

Right. I have heard of problems with Ampex. It may possibly be made worse
by the higher temperatures in the US compared to the UK. I store my
archive tapes in sealed containers in the cellar which keeps cool year
round.

(I also have recordings on Maxell tape that seem to be fine.) And no,
my machine does not use NAB hubs: I was referring to the spools that
hold the tape itself. I have a couple of tapes on metal spool, but all
the rest are plastic.


The large pro 10 1/2" reels of 1/4" tape are referred to as NAB reels in
the UK. So the hubs as NAB too. Most machines used 'NAB' adaptors which
could be removed to take a 'cine' spool as standard domestic types were
called.

Good domestic machines like Revox used the same idea.

European broadcasting companies used AEG metal centres, with the
tape sitting on a backing plate when on the tape machine.
These centres might be a much cheaper alternative to NAB reels.
Be aware however, that you should spool anything other than
matt-backed tape onto these centres at a very low speed.

Generally not all decks have matching plates to allow the use of AEG style
hubs.
ReVox/Studer does. I believe Otari has it to. Telefunken and a lot of
other european
brands does too.

For consumer machine though it is typically not possible unles you know
someone who
can make you one from scratch. These machines were never meant to have the
ability to
play tapes using the AEG hub & plate system.

Agreed. I was not thinking about playing these tapes from AEG centres,
but using the hubs when baking the tapes instead of the much more expensive
NAB flanged reels.

I'm a bit late here but one suggestion would be to bake at a lower
temperature - say 40 degrees C but leave it for longer. This would be less
likely to cause damage to a plastic reel. Normally I take the tapes up to
50 degrees and leave them to cool slowly overnight - this wouldn't melt
plastic reels but might cause them to warp a little.

Cheers

James.
