Currently manufacturing a 16″ diameter 1″ thick  plate glass f3.88 Newtonian telescope mirror. Doing this with my new fixed post grinding machine built this summer. Work is progressing well, and very efficient. Started project in August 2013 and at this point I am ready to move on from 25 micron White Aluminum Oxide to 9 micon White Aluminum Oxide. Cold weather here in North Texas has put quite a damper on the work, and it has been the coldest December ever recorded!!
