    I was having trouble getting down in the deeper holes here on the Mississippi River. I have some 14 and 16 ounce roll sinkers that just would not do it. So back to the shop to design up something that sinks..

    This mold was made from a drywall mud tray that I poured in unsanded grout for tile. The drawback to using unsanded grout is that it will break relatively easily as you will see in the picture. The other drawback is that you need allot of it to disperse the heat when pouring the larger weights over 10 ounces. The way to really go is to build a small box out of plywood for the bottom and 1x4s on the sides. This way you have a try instead.

    I sprayed the empty mud tray with some WD40 so the grout would not stick to the sides of the try. When mixing the grout up, try not to whip it as this will add air bubbles. I normally will add extra water than I need so that it will form a crust on the surface and also be easier to work with. Find yourself several sizes of plastic or rubber balls. Once you pour in the grout and smooth it around, push the ball down in the mixture. It is best to turn it while inserting. When you get the depth you want, just run duct tape across the top so that it will stay there. Shake the mold some to even out the grout is another reason I added more water than needed..

    As the grout starts to harden, take the tape off and lightly spin the balls creating a smoother surface in the insert of the mold. You can add a few drops of water if you see air bubbles when you pull the ball out. Put the ball back in and respin to smooth it out more. Let this dry atleast 5 or 6 days to insure that all the water content is out. I will then spread a light coat of oil into the cavities to prep the mold for pouring.

    To make the clasp, I took a 3/0 snap swivel with the clasp and open and bent the clasp part. Refer to the picture to show placement before pouring the lead. The swivel helps with line twist so leave it on. The one shown makes about a 14 ounce weight that is round on the bottom because of the ball and flat on the top.

    Great Ideal Vince, Do the sinkers come out of the mold pretty easy and how long do you wait? And also,how are you rigging them when fishing?
    Thanks, Rob

    Thanks for reminding me about the cooling part Rob.

    Let them cool down for about 2 minutes when the lead is set up. Do not handle for atleast 15 to 20 minutes without gloves on. This is why that I have the forceps already clamped on to just lift them out and place them on the concrete floor to cool.
    We all know melted lead is roughly 500 degrees. Be careful as not to pour many as the mold will get very hot. Pour maybe 3 then let it cool down. ALL of this is mainly common sense but you can get hurt severely. When I pour weights, I am normally pouring 3 or 4 molds cycling them letting them cool.

    This weight works great as a 3 way drop for going deep. I have even used it as a slip sinker holding the edges of scour holes on wing dams.

    Great idea, Vince. Thanks for the documentation. This'll be library material for sure.

    Have u ever tried using a old fasion ice cream scooper the ones with the push lever? all u need is the scooper part, I just sink a barrel swivel in the lead before it sets up.
