In my blog I would like to share information about old metal forming technologies and to receive feedback. The first project is an a<a href="http://4.bp.blogspot.com/_i8wIaUY087I/S_lU5GJMCKI/AAAAAAAAAAM/8CJYFhNlug4/s1600/DSCN0105.JPG"></a>nticlasting bracelet.<br /><br /><a href="http://2.bp.blogspot.com/_i8wIaUY087I/S_lhD6rDPlI/AAAAAAAAABE/GkdGb4DGybw/s1600/25022010115.jpg"><img style="MARGIN: 0px 10px 10px 0px; WIDTH: 320px; FLOAT: left; HEIGHT: 240px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5474513541962874450" border="0" alt="" src="http://2.bp.blogspot.com/_i8wIaUY087I/S_lhD6rDPlI/AAAAAAAAABE/GkdGb4DGybw/s320/25022010115.jpg" /></a><br /><br /><br /></div><br /><br /><div><br /><br /><br /></div><br /><br /><div></div><br /><br /><div><br /><br /><br /></div><div><strong></strong></div><div><strong>Step 1 - Preparing the cylinder.</strong></div><br /><div>For the bracelet I cut a strip of 1mm copper sheet to 50 x 264mm. with a fine saw cut 4 slots about 10mm from the edge. Bevel the six contact surfaces in opposite directions in order not to increase the material thickness after soldering.</div><br /><div></div><div><a href="http://3.bp.blogspot.com/_i8wIaUY087I/S_lbGGjfLKI/AAAAAAAAAA0/OHVPowLptlc/s1600/26022010117.jpg"><img style="MARGIN: 0px 10px 10px 0px; WIDTH: 320px; FLOAT: left; HEIGHT: 240px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5474506982442347682" border="0" alt="" src="http://3.bp.blogspot.com/_i8wIaUY087I/S_lbGGjfLKI/AAAAAAAAAA0/OHVPowLptlc/s320/26022010117.jpg" /></a></div><br /><br /><div><br /><br /><br /><br /></div><br /><br /><div><br /><br /><br /><br /><br /><br /><br /><strong>Step 2 - Preparing for soldering</strong></div><br /><div>Anneal the metal, roll it to a cylindrical shape, match both ends of the copper strip and hammer the joint area to full contact. Bind the cylinder with a steel wire and put some spacers in order to prevent the wire to be soldered to the copper.<br />Solder the cylinder from the outer perimeter. (The outer perimeter of the cylinder is going to be the inner perimeter of the bracelet).<br /><br /><a href="http://3.bp.blogspot.com/_i8wIaUY087I/S_lhzpbZoRI/AAAAAAAAABU/J4-1WNc3--8/s1600/DSCN0014.JPG"><img style="MARGIN: 0px 10px 10px 0px; WIDTH: 320px; FLOAT: left; HEIGHT: 240px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5474514361967550738" border="0" alt="" src="http://3.bp.blogspot.com/_i8wIaUY087I/S_lhzpbZoRI/AAAAAAAAABU/J4-1WNc3--8/s320/DSCN0014.JPG" /></a><br /><br /><br /><br /><br /><br /><br /></div><br /><br /><div><br /><br /></div><br /><br /><div></div><div><br /> </div><div>This is how it looks after soldering and pickling.
