remove & reuse dust cap?

[bb-3]

I would like to remove the dust cap on one of my (Infinity Qe) woofers that is pushed in a bit, pop out the dent and reuse it. Is there a good way of removing a dust cap without damaging it? This cap looks pretty thick, and I would like to have it match the other one (I may not use the grill cloth).
These are paper cone speakers.

i reuse them all the time. i'll slit the cap with a SHARP razor knife , as close
to the cone as i can , then to replace , i use contact cement or yellow wood
glue.

you can also poke a hole in the center of the cap , insert a bent wire to push it out , then a dab of glue to fill the hole.

sometimes, a piece of duct tape will pull out the dent.

Razor knife, what is that? I have an X-acto knife, but it may not go close enough to the cone? Do you try to take off the remaining glue & cap after removing it from the cone, if so how?

Karlo's bent wire trick should work. I'd try using two sewing pins inserted at an angle into the center of the dimple and pull up. I wouldnt remove the dust cap. JMHO

any razor blade . x-acto ,or otherwise...just be sure it's sharp , or you'll
tear the cap instead of cutting it . i always just leave it alone . there's going
to be a small seam left where the glued piece meets the tiny bit that is still
attached to the cone..... i've never really cared that it was pristine- a bit
of extra glue at the dustcap isn't going to hurt the sound.


otherwise....$1.25 will get you a pair.

he has other sizes too....

there's also the vacuum cleaner trick... just don't use too much vacuum (no contractor
-grade, 15 hp wet/dry vacs!)

you can also try using suction, like a vacuum but, BE VERY CAREFUL!

Oh', I get it, you leave a little still on the speaker, and then glue it back on that little part you left.
These look like VERY thick caps, nothing like the ebay ones. I don't think the hole or vacume would work there SO thick?

Tried the tape method, no way. These caps look like there made of paper mache....that's why I want to keep it, aftermarket ones look nothing like these.

I slit around the base of the cap just above the existing glue line. I start just past where the tinsel (wire) leads go through the cone (usually two dots with wire/glue going under dust cap). I slit around until I get near the cap and the other side of the tinsel leads. I NEVER CUT NEAR THE WIRES. Then hinge the dust cap back on the little bit remaining over the wires. Do what you need to do and re-glue back to the original line. It always comes out nice and it fits exactly as it's fitting back onto itself
