The coat hanger will work fine. Although for larger fuses, probably
won't have the strength to really work the seam the full length of the
fuse. A method I learned while working with the Master himself, Mark
Allen, was to use a "roller" on a stick. We'd use a piece of brass tube,
I don't know the exact diameter, maybe 3/8", maybe 1/4", a short piece
of hanger wire (shaped like a "U", and a roller of some sort on the end.
I've used all kinds of things to create this roller: 3 or 4 quarters
with a hole drilled in the middle, pennies or dimes, I've even cut the
end off a X-acto Knife and drilled a hole in it. (It all depends on the
size of the fuse, and the access you have) Use the wire, thread it
through the hole in your roller, and stick it into the end of the brass
tube. Make certain that it rolls VERY freely. Now you've got your roller
on a stick. You can use this to get all the way down your mold to (maybe
you've heard this term) "roll out the seam." It is important to design
your mold to give you as much access as you can. Cut away the segments
of the mold where you're going to cut the finished part. This will give
you access. You'll find that by using the brass tube, you can bend it to
get into the hard to reach areas.
This way you'll find you can roll the whole seam, and end up with less
voids. It also won't tend to pull the cloth like a bended wire might.
You can really wail on it! It'll take some practice, but you should be
able to make perfect fuses in no time flat.
Store the end in a coffee pot of acetone or denatured alcohol, and it
will be ready for it's next use. If it does freeze up on ya, we used to
hit the end with a torch, and burn off the cured resin. (Although I
don't recommend this, cuz this could be hazardous to your health) But it
is kinda fun!
Good luck with it, and let me know when you've got it perfected. For
some reason, I always need fuses. ;-)
