I've been fairly happy using Lineco's document repair tape for
repairing rolls: http://www.lineco.com/cart.php?m=product_list&c=579 
A similar product is their pressure-sensitive mending tape:
http://www.lineco.com/cart.php?m=product_list&c=1243 

The document repair tape is 1" wide while the mending tape is 1/2"
wide.  They share Lineco's description so they may well be the same
product.  The stuff is fibrous, removable and archival.

The problem with the document repair tape is that it is 1" wide and
very few repairs need that width.  I therefore cut lengths of tape to
1/4" or 1/5" wide, using an X-acto blade and a steel ruler.

Wouldn't it be dandy to find 1/5" wide tape which would repair edges
of Ampico A rolls?  Ampico B rolls would require a much narrower strip
or repunching those few sub-intensity perforations.

Perhaps some clever soul has invented a four-X-acto blade cutter that
would take a 1" roll and slice it into fifths, preferably without
effort, excessive cursing, or blood.  Since the document repair tape
is both fibrous and sticky, the cuts need to be clean.

I poked around the 'net and came up with nothing better.

Using a couple spool boxes I built a poor-man's roll repair table
that's got a Borco, drafting board vinyl, a cutting/work surface but
it does not have the clever flip-over function some other MMD-er made.
