Wooden Sinker Moulds

I've been browsing round the internet and it seems that it is possible to pour lead into wood.

Yes, the wood charrs a little and I assume that it won't last as long as the aluminium ones, but they are dirt cheap and I just whipped one up in about 15 minutes from off-cut crap in the garage...

Drill some pilot holes for each sinker pot (or just wing it from the hip like a cowboy)

I'm making 3oz bottle shaped sinkers, but I'm sure you can scale the whole design up to any size. First drill a larger hole all the way down to the depth of the neck of the bottle (Note the mark I made on the drill bit to indicate depth)

I modified a 19mm drill bit to the bottle shape by simply filing it down. Remember to file at an angle to create a cutting edge.

I marked the target depth on the blade and drilled each hole wider, simple...

Close the mould back into the vise and drill small holes from the top for the wires...

Drill some holes for the nylon to make it a grapnel sinker. Remember to drill at an angle...

Clamp the whole lot and weave the nylon through...

I don't have anything to melt my lead in a pour it, so I'm going to try using a tin can.

Now, I'm taking a bit of a gamble here, but I think they make tin cans out of steel these days. If I'm wrong, then the can will melt with my lead, lol...

I cut the top off the can and rivetted it to an old off-cut piece of aluminium to make a handle. The can is nice and soft so I bent the bit on the side to make it pour easier...

The whole lot is ready to go, I'm having a braai this afternoon so I'm going to put the fire to good use.

Hopefully the whole lot doesn't catch on fire or something, but I'll keep you guys posted...

Poured the lead into the wood, and what do you know, no need for a fire extinguisher. .

Opened the mould and the sinkers are perfect bottles. Only problem is that the nylon melted away completely...

I think there might be a trick to add the nylon afterwards or something, anyone?

OK, so I made a mistake with the nylon before pouring the lead...

You have to add the nylon afterwards:
1. Drill the holes.
2. Melt the tip of the nylon with a lighter.
3. shove it in the hole.

Easy!

Great post! Thanks for all the pics! I think instead of drilling holes afterwards for the grapnels you can insert nice thick wire in the mould nylon holes and pull it out shortly after you poured the lead. It will keep the holes for the nylon open. I will be skropping in my garage for a nice and hard piece of wood for a mould of my own.
