do the spider first, then the surround. You can push the spider down by hand and hit it with accelerator. I lay an MDF disc on the raised part of the surround with a 5# weight and hit it with accelerator. It's dry almost instantly when using accelerator...
dont put the accelerator on until your target surfaces are pressed firmly together. the accelerator will dry the glue within seconds and you will not get a good bond if you press the surfaces together after.
There are several ways to do it. If you have the coil shimmed tight as you should, you can move the coil up and down only with a little extra force. Coil/spider joint should be done already. Put a good bead of CA on the spider landing. It needs to be thin enough viscosity to soak into the cloth but not too thin so it continues to wick farther into the cloth. If that happens, when it dries it creates a hard edge where the spider will wear prematurely. Put the bead on and push the spider down into it by sliding the coil down the pole. You should see the CA soaking through all the way around. You can move the coil up and down slightly to help force the CA into the cloth then spray the accelerator. If you see spots where it didn't soak all the way through all the way, slide the coil up an inch or so and put a little more CA on the spider landing in those spots.
For a foam surround you want a rubber based cement that has mild solvents to not dissolve the foam. CA will eat right through it. For rubber surrounds you'll want a thicker CA and you need to use the right adhesion promoter based on what type of rubber it is. Santoprene and EPDM need a much different primer than does Butyl or NBR. You can then do it 2 ways. Pull the coil up to put space under the surround. Wipe the surround with the primer and then wipe it with the accelerator. Then put a good bead of CA down on the frame. As you push the coil back down the surround with accelerator will contact the CA and begin to cure right away. This works very well and quickly for very stiff surrounds. For softer surrounds you'll need to put the bead of CA on, clamp a ring down to hold pressure, then spray accelerator on the bead that will squeeze out on the inside, underneath. Let it dry for an hour or two and take off the ring. Make sure the ring is something CA can't stick to like HDPE, or make sure you put a layer of plastic wrap underneath. Gluing chunks of and mdf or plywood right to the surround doesn't work well //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
