put shims in place, glue on spider landing, place recone in place, push down and hit with activator and hold it in place. 45 seconds later it's done. NO need for clamps/clothespins when using CA glue/activator.
For the surround I use a sub cutout on top of it with 10-15#'s of weight. Assuming it lays flat then hit with activator from the top and underneath the basket. Give it a few minutes and check for loose spots. Might need to hold those down and hit it with activator again.
Make SURE you remove the shims before gluing on the dusctap....
