It can be done, as if there was any doubt.<\/p>\n<p>I started with a 2&#8243; diameter 3&#8243; long wax cylinder. On the Taig micro lathe I turned half the length down to just over 1&#8243; (not critical) so it could be held in the self centering 4 jaw chuck shown here. Once in this chuck it was never removed until finished.<\/p>\n<p>I machined the inside on the Taig CNC mill as a 3D pocket. Then I switched to the 4 axis setup and ran the outside profile. When finished is shown in the first picture.\u00a0Note the smooth finish that is possible.<\/p>\n<p>Then I went back to the lathe (still in the original chuck) and turned down the stem and\u00a0top of the bell. It would have been too weak if I had done this earlier. The big end will be cut off before spruing for the cast.<\/p>\n<p>Not bad for a first try but still a lot of things to tweak.<\/p>\n<p>The next bell I will spend more time on the CNC picture taking. I&#8217;ll do some video of the machining action. There was quite a pile of wax chips and turning ribbons. That green wax is a joy to machine. The bottom three pictures shown are more fitting I suppose for the lost wax casting over in &#8220;Ramblin&#8217; Dan&#8217;s Workshop&#8221; than here in the machine shop blog but to get to this point there was a whole heck of a lot of CNC machining and some manual lathe work.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Yes!
