Looking on line I located this article explaining how to make your own
nitrocellulose glue.

What!? "Green" ambroid?... As printed in the September 2004 Windy Sock, the
Newsletter of the San Antonio Alamo Escadrille, Joe Joseph, Editor We have
seen a report, unverified, that acetone will no longer be used in the
manufacture of ambroid (nitrocellulose) cement. Skeptical at first, we
later noticed that our Duco cement didn't seem to hold things together as
well as it had. Never hasty to condemn the environmentalists ("green"
movement), your editor chuckled over their efforts to save the bugs down
deep in the caves from extinction. But hey, this could be serious; to us
old timers, ambroid cement is the patriarch of our hobby. But what if the
report is true, and we must now tolerate a weaker glue? In the old days,
guys dissolved toothbrushes in acetone to get a good quality ambroid cement
but who knows what toothbrushes are made of nowadays? You might get who
knows what, or nothing at all. Well, an item came up on the Internet
recently (www.pyroworx.com) that we should keep for "just in case"; it told
of how we can make our own nitrocellulose lacquer, which is simply diluted
ambroid cement..

Here's the way it goes: Materials: 4 table tennis balls (defined as "two
star", whatever that means); 14 ounces of acetone; a 500 milliliter (17
oz.) glass jam jar with metal screw-on lid; and a stirrer. (1.) Pour the
acetone into the jam jar. (2) Put in the table tennis balls. If you can't
fit all at once. just put in as many as you can, and let them dissolve.
Once they have dissolved, you can put in the remaining balls. It'll take a
couple of minutes for the balls to dissolve. They will get all mushy and
break apart. Use the stirrer to make them dissolve faster. Be careful not
to get any of the lacquer between the lid and the jar; the lacquer will
seal the lid permanently on.

PS You can find a box of 144 #2 Cellulose Table Tennis Balls for around
40.00USD. I would purchase a can of Automotive Acetone rather then the
stuff they sell in Drug Stores/Pharmacy as the Drug Store brands have a
fair amount of water in them.
