Well I read though the thread and have a general idea how to recone, so the shims go inside the coil before you drop it in the motor? Are they there so when the glue sets up on the spider the coil stays straight? Just trying to get a strategy for when I go to recone my tc9 based eclipse since the coil is a good tint of black.
Any idea how much crap will be in the gap since the coil has been rubbing for 4 years? Also how do you get that crap out, just pieces of masking tape folded over with some exposed sticky?
Yes the 'shimms' go inside the gap between the pole piece (metal part of the motor) and the voice coil. This assures that the gap is correctly aligned so that you don't have any rubbing.
Also, after 4 years of rubbing you are going to have a lot of gunk inside the gap. You might try either canned air or an air compressor to 'blow' out the gap first. Then use masking tape to finish cleaning the gap. If the gap is really deep try attaching the tape to a note card or some other rigid thin object. Just make sure it isn't metal.
CA glues does not equal super glue (if you are thinking the stuff sold at Wally's World in the small metal tubes that burns your eyes and melts things). I have had decent luck with Goop and a few other products. But, if you can get a CA glue made for loudspeakers use it. I'm sure some other people on here know where to get it. IIRC Parts Express might sell it.
May be a old thread but I thought I would put my 2 cents in..
When I'm fixing a surround or spider I usually use the 60 second 2 part epoxy you buy at walmart for like $3. It works well and I haven't had any problems with it yet. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
