A few fellers have asked me about these ,so here they are. My kids are bigger so I don't have baby food jars anymore ,and I switched to other lids .You also need washers and duplex nails .
First I grind or file off the top head of the nail and punch or drill a hole in the center of the lid .Then I put the washer on from the ground end ,and the lid on top .I silver solder the two together in place .(silver solder will flow between the lid and washer )
Last I braze the lid to the nail from the front .
This point weighs 281 grains now .It will lose a bit when I trim the length of the nail .
