All I do is turn them upside down so that excess water runs off, maybe about 20 minutes and then cut a flat on the bandsaw (careful of those fingers), once you have 1 flat it's easy to cut the other 3 flats. If they are soaking wet I dry them off with kitchen towel and immediately CA them making sure that the CA is flowing downward into the (for want of a better word) petals. once the CA has gone off I put them in the chuck and drill a 5mm hole to aid drying. Leave them to dry for a couple of days and then with the cone blank upright I drizzle CA in and let it dry and drill it to size. My first one I didn't bother to drill it and let it dry, i just drilled it and glued the tube in, it was fine until I got to almost finished size and something flew out and I had half an inch of brass tube showing, i glued it back in and it wasn't noticeable. Be aware that you will get seeds and some of them you will turn off and you will be left with seed sockets, you can fill then with whatever you want.
