Short of a new cone what is the best repair for a

Just a tear ?

I use a glue pen and cover the whole cone. It will rebind the fibers, not stifen the cone and will be barely if not imperceptible.

Here's 3 short videos (about 1.5MB each) I made on the subject:

I buy my glue pen at dollar stores. Someone bought Elmer's glue pen and reported excellent results.

Thanks for posting the videos! What is the brand name of the glue pen you use? And are you referring to Dollar General Stores or dollar stores in the generic sense? I will want to try it but I do not know if there are more than one kind of glue pens. I am naturally prone to grab the wrong product for "any" shopping experience to which my wife will testify. :O) Bob

Generic Dollar Stores. Some of the glue pens I tried dried a little harder. Best would be to buy 2 or 3 types (I pay 1$ for 3 long tubes) and experiment on a sheet of paper. Use the one that dries the most flexible. I had to buy 4 or 5 type before I found the correct one. Cost was 5$. My kidz took the ones I didn't like...;o)

Doesn't take much, so a tube will last a loooong time.

Someone bought the Elmer's brand at Wal-Mart. The cheaper the better....in this case.

Bob,
I've been successful using watered down water based craft glue, and painting on with a brush like paint.
Its a craft glue that dries to a rubber like consistency, and made for cloth/paper. Although I've never ran a cone through a wash cycle, it claims to be waterproof once dry. Using a fine bristled brush and a light touch the tear can be sealed. Of course the two sides of the tear must be positioned properly to be joined during the drying process. Take care not to distort the paper cone in such a way as to disturb the axial alignment with the voice coil/gap. If there is any chance of severe cone distortion, you might remove the voice coil dust cover (usually felt), and use shims to maintain the gap during the glue application and drying process.

:tear in a 12 inch speaker? One fellow suggested to use a toilet paper a bit larger than the size of the tear, and brush on rubber cement over it. It worked for me.

Thanks for the help. Thought there was something
better than tape.

Hi, Bob. I don't believe any of the good suggestions you received involved tape.

Thanks Doug what i ment was I knew tape was not
a good idea.Fortunately the tear is small but
this brings up another problem.This is one of two
12 inch speakers in a 1936 16 tube M&W 62-197 that
is supposed to crank out 30 watts.I presume one could
easely damage these old speakers with too much volume.
Is there a practical way to fuse them? THanks
Bob
