Large, deep holes can take a long time to grind out if you start with the finest burrs and gradually work up in size. But here is a situation where I saved myself lots of time, by using a large, coarse burr, set in my drill-press, where I could apply more pressure to the work.
When I assemble the eight pieces of stone I’ll use a piece of threaded brass with nuts attached to hold them all together. To help them hold, I ground out the top and bottom holes with a keystone shape to make sure everything will stay together once it’s assembled. Now all I need to do is make the time to complete the piece!
On this page I intend to add monthly updates on aspects of jade carving. I also plan to invite more experienced carvers to offer a "master-class" on a particular subject of their choice. With this I hope to enthuse both the novice and the expert in this ancient and beautiful art-form/craft. And comments are welcome!
