I have read original article, viewed the video and read each of the questions/answers — all of which were useful.
Finding the Google Sketchup drawing was a particular treat since I am using that software to design my next project.
I am building a stand/platform/table for an early 1950s Lathe that my grandfather had. Two of the primary design goals are that the Lathe can be moved (I have a hydraulic lift table) and when not in use the area can be used as a working surface.
To accomplish these goals I am taking various ideas from several people. The “traveling portion” will have a wood stand with very heavy legs (panels actually) with vibration damping in the frame. Until I saw your ideas I was planning on using two sheets of 3/4″ MDF supported by 2 x 4’x (again with vibration dampening).
I very much like your idea of using removeable mdf panels to suit the task at hand. In this case, one of them would have the lathe mounted on it and have an opening to exhaust wood dust and chips. Do you forsee any particular problems with using a much thicker and more rigidly supported top?
