Let that fully set/harden, probably overnight. You can get some leveling of the JBW if you warm it until it thins a bit. Leveling is not so important at this step, but heating will also slightly accelerate the curing process, and you will want to get a feeling of heating so that you can level the last batch of JBW for the top of the puck.When JBW is fully hardened, pull the wire out the bottom. You need to be able to re-insert the wire if a coffee ground plugs later, so get a feel for it now. It will probably take pliers to grip for pulling the first time. Re-silicone and re-insert and pull and insert a few times until comfortable.It you cut the wire on the end that goes through the epoxy you may have trouble. Wire cutters slightly crush and flatten the wire. If you have to use a cut end, deburr it or remove the crush so that it is round. I held the end of the wire against a Dremel sanding drum or grinder and turned the tip over, sharpening it if you will.
