 Posted: Mon Nov 20, 2006 1:40 pm Post subject: Some tips on using self-sticking Velcro |
 |
|
In my various capacities as supplier to the OBAM aircraft
industry and skunk-werkser on the TC side of the house, I've
found many uses for the self-mounting, pre-stickied Velcro
products sold by Hobby Lobby, WalMart and others. On of my
favorites is a "Heavy Duty Adhesive, Industrial Strength"
product I've been buying at WalMart in the crafts department.
A 15 foot by 2" wide roll is about $8 as I recall. I've
never encountered a situation where holding power of the
Velcro was lacking but getting the adhesive to stick can
be iffy on some surfaces.
I've found that wiping the surface down with acetone (pure
acetone available in cosmetics as nail polish remover. 8 oz
for about $1.50). Then use your heat gun to warm the adhesive
to as hot as you can stand while holding the Velcro in your
fingers. Stroke it for a minute or so under the heat gun.
Press into place firmly and know that the bond is somewhat
time sensitive. It may take 24 hours to reach full bond
strength. Putting this stuff down with the technique described
has produced some amazing attachments . . . some have required
the heat gun to re-soften the adhesive so I could pull the
stuff up. I've used this technique to install remote mounted
instrumentation packages in the hell-hole on airplanes and
in the nose compartment with results that amazed folks I
was working with. One skeptical technician didn't think Velcro
would hold this 5 pound data acquisition signal conditioner
in place.

I invited him to remove it after I'd installed it. He had
to go get a pry bar to open the Velcro interface and we
needed a heat gun to get the adhesive to let loose of the
airplane when we were done. He's convinced.

I've used velcro strips to route the wiring in my tube framed Delta. 3M
sells a product at the big box hardware stores that is a roll of 6"
strips with a slot in one side. I wrap the strip around a tube and
through the slot, which allows me to cinch it down tight to the tube.
This will leave a layer of velcro between the wire and the tube. I
orient the strip so that the remainder will 'cup' or 'catch' the wires.
I space them about every 6 to 8 inches, and one on each side of a
corner. I don't pull the velcro down tight untill I think I have all
the wires routed, but then the strip will go around about 3 times. I
apply as much pressure as I can while wrapping it. I can pull a single
wire of a bundle through about 3 or 4 straps, unless it's around a
corner. In that case, I have to pull a loop into the corner and then
out to the other side. I haven't been able to pull of wire off of a
tube, yet. The velcro lays down very smooth once it has been rubbed
down good, and you have to search for the end with a fingernail if you
want to pull it up and adjust it. You can slide a single strap from
side to side, if you're patient.
It works well to bundle wires together also, but you can't get it as
tight as you can when you have the steel tube to pull against.
