Everything that goes into the design and construction will have some elements from their cultural background. Their mother and grandparents lived and worked in a copper mining town in Chile and copper was a big part of their lives. To bring copper into the design, I will attach the legs to the box using copper rods. Since the legs taper, I will use 1/8”, 3/16”, and ¼” rods and leave a ¼” gap between the legs and box. But this is subtle and I wanted to add something else. So I want to add a copper sphere at the top of the box. I drew up the design full scale and the sphere looks good at ¾”. So, I started researching copper spheres and what I found are jewelry spheres ½” and less or solid spheres 1” and greater. I ordered the 1” spheres which are actually used for plating copper.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'> So here are some of my issues/questions/concerns:<o:p></o:p></span></p><ul style='margin-top:0in' type=disc><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo1'><span style='font-size:12.0pt;font-family:"Arial",sans-serif'>Is there any way possible to reduce the diameter? I thought about some kind of holding contraption on a lathe and then using files but that just sounds like a bad idea.<o:p></o:p></span></li><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo1'><span style='font-size:12.0pt;font-family:"Arial",sans-serif'>The sphere weights in at 3 oz. Now that may seem light but it’s a little heftier that I wanted because I don’t want it to tip the box over when hinged open. The box footprint will be 8”x12” so it may be OK. I will build a prototype as I always do so I’ll find out. Also with a prototype it will be easy to see if 1” is too big. A ¾” hollow sphere would be perfect but I can’t find that.<o:p></o:p></span></li><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo1'><span style='font-size:12.0pt;font-family:"Arial",sans-serif'>Will solid copper drill OK? I would like to drill a hole for a rod to anchor the sphere to the box. I will epoxy the sphere to a cradle but a rod would be so much more secure IMO. And, given the weight, I would feel better.<o:p></o:p></span></li><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo1'><span style='font-size:12.0pt;font-family:"Arial",sans-serif'>Here’s another take …. Is there a way to cut the sphere in ½” I only have WW bandsaws so even with a metal blade, WW bandsaws run too fast, don’t they? The thought process here is maybe I take the two half spheres and attach them to the side of the box as an adornment. The design will be mostly Asian so spheres might look good. <o:p></o:p></span></li></ul><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'> So you can see the design is in total flux.
