THIS IS FOR WOOFERS WITH THE PLASTIC CENTERING CAP ** If you do not have the centering cap use Amazing Goop for the dust cap ** Seems people have ALOT of problems putting caps on their re-cones so this is how it is done : Buy two of these containers of Loctite FIVE MINUTE epoxy w/ mixing tubes at Lowes (DO NOT USE ONE MINUTE): ---------- First Step : http://www.sundownaudio.com/misc/how-to/Nightshade_Dust_Cap/CIMG2514.MOV Put epoxy around the edges of the disc as shown - make sure to get a good bit in the little holes so it is filled in. ---------- Second Step: Wait about 5 minutes for the first step to dry. http://www.sundownaudio.com/misc/how-to/Nightshade_Dust_Cap/CIMG2515.MOV CAREFULLY make a bead around the dust cap to fill in the gap area. You will see Brandon traces back a bit at the end - this is because the epoxy keeps dripping out a bit and we don't want it on the cone. Don't put too much or it will run over onto the cap!
