Re: Turning a hollow blank

For a chisel handle the dado only goes part way through, so the idea of a glue block over the opening sounds right. But for a lamp base, your idea sounds great and I can't wait to try it!everettdavis wrote:Post some pictures of your project and let us know what worked for you.
Since it was dados glued together, you do have a square hollow center if I am understanding you.
Since it is split and glued together, even an internal 4 jaw chuck on the inside could split it open when torqued. On the outside, you may lose access to surface you need to tool.
The plug method is likely the most stable option.
I once had a maple lamp stand with a square hole that I was able to use a 1/2" threaded rod through with both star and spacer washers and threaded nuts and jam nuts on each end, and I used the drill chuck and a bore hole live center in the rod.
