twisted wire insert-2
This is a follow on from my previous posting .
I wanted the wire pattern to be a bit more prominent, so I tried 2mm thick wire .I found this to be more difficult to bend to an even circle and it was a tight fit in the groove , infact I had to hammer it in, but the pattern came out pretty even .I then decided to try 1.5 mm wire , in this case aluminium wire . I found this was easy to bend into the groove and about the right thickness but I still havn't found how to get the wire to lay flat in the groove as evident by the variation in the pattern .
I had a bit of twisted wire left over from my first attempt so I used it to embelish the lid of a screw top box .
It is difficult to determine just how much wire to twist . It is easy to calculate the circumference of the groove but the wire becomes shorter as it is twisted and how much it is twisted .I also have to allow for a bit of damage to both ends which has to be cut off .So far I havn't made it too short but I don't like wasting wire . I am keeping records, so eventually I should be able to minimise waste .
The bowls are camphor laurel and the STB is camelia . All are finished with DO .
Hope this is of interest .

I like what you are doing, Ted. It adds a very interesting and compatible feature to the bowls.
Re: the wire sitting flat... could you have the wire sitting slightly proud of the top surface so that you could put a weight on top to keep it flat while the resin was curing?

Ted, you did a pretty decent job on those last two pieces you did. You just need to stretch the wire after it's twisted, then solder the ends and stretch it again. Then start turning your piece to fit the wire. Below is how I've done a couple pieces, and below that are a couple pictures of the only one I have left.
I've done a couple twisted wire pieces so far, but over 8 years ago, two years after I first started turning. I turned the rough shape, then parted it into 2 pieces. I got my OD measurement, subtracted 1/4" or more of the diameter, calculated the length of wire, and cut the already twisted and stretched 10 gauge wire. Stretching the wire also straightens it. I sanded the cut ends to give a good smooth surface for the solder. I then separated the wires on each end with a knife so each end of the wire got soldered, not the wire itself. I didn't want the solder to run down the wire, only on the ends where each joined. After stretching on the mandrel I made, the wire was now a flat ring. I started turning one of the pieces to accept the ring with a tight fit. I also cut a rabbet on the inside, leaving an eight inch thick tongue. On the bottom half, I made another rabbet, and joined the 2 halves together with regular glue, careful not to get it in the wire groove.
When the piece was turned, all wire looks to be the same length, and same diameter. The joint was soldered with gold solder, so it's very hard to find where the joint is. Pictures below.

Over the years the lacquer has started to come off the copper, and I don't know what the white residue is on some locations. Otherwise, it's uniform.
Next time you make one of these pieces, try soldering and the stretching the wire over a mandrel made from your next roughed out turning. You just need something pretty hard, and a diameter that will accommodate the next piece you think you are wanting to put copper in.
What are you using to twist your wire? Also, it doesn't look to be twisted very tight. If you have any questions, please ask................ Jerry (in Tucson)USA

I don't think that would work because the resin would run everywhere .I actually make the groove about a mm deeper than the thickness of the wire then taper the top edge of the groove so's I can pour the resin in without spilling it over the edge .I am going to make a weighted jig to hold the wire down in the grove and stick it down with CA one section at a time .

Thanks for your suggestions .I twist the wire by holding one end in a vice and the other end in a cordless drill .
