Wm. R. Robertson Posted April 23, 2014 Share Posted April 23, 2014 As many of you know the Thorne Rooms at The Art Institute of Chicago have been adding items to decorate them for Christmas so what could be more perfect than a Wassail bowl for a Tudor room. This is adapted from the design of a English example from the 1600's. It is made of Lignum Vitae and old ivory. It is about 1" in diameter and 1 3/4" tall and I did this in 2010. Now for how it is done....... the parts are turned to shape and then mounted on a rose engine, this one is French from about 1840-50. The machine is hand powered and I run it about 2 rpm with depth of cut between .001 and .002"..... so some of the deeper patterns take about 10 minutes per line. To hold the work I mount it in a collet holder, either ER-16 or WW... that goes in a 3 jaw chuck, I have adapters made to adapt the odd size rose engine threads to the spindle threads of a Rivett lathe...... all this can be trued up with a centering chuck that is pretty standard on a rose engine.The bowl was bored first with a ball mill, screwed to it's mandrel and turned to size then transfered to rose engine....Here is the lower ivory piece being done with a form tool Link to comment Share on other sites More sharing options...
