      I recently had to solder a thin wall brass tube to a strip of brass, and wondered how I was going to hold it at right angles to the strip. After much pondering, I came up with this idea and it worked a treat. The ME site insisted on turning the photo 90 degrees for some reason. 100_2127.jpg

          Your drill table will make a fantastic heat sink. Suggest some firebrick or similar under the joint

            Kitchen fire blanket will do if you have one.

              If it is low temp/tin lead solder, a bit of wood should be OK for a joint like that, with both parts tinned, a reasonable sized soldering iron, a matter of a few seconds heating, and a wee bit more solder, job done. For some reason if I was using silver solder, and a gas torch I would be keeping away from the lathe or drill press and set up some form of jig(Don't know why, it's just me).

                With you on the heat sink problem gents, but as the tube was 5mm thin wall, and the strip was 10mm by 2mm I thought the small pen type gas torch would very quickly get the parts hot enough I didn't bother with a fire brick. Ian, I did spend some time contemplating making a jig but I thought that that would take as long as making the item it's self.

                Cheers Dek.

                  Dec, are you using silver solder, or tin lead?

                    Tin lead Ian, which is why I was not too bothered about loosing a lot of heat. With the bit to be soldered over the centre hole of the table, it only took a few seconds to get hot enough.
