Any one intereted in making there own sinkers and has trouble finding large
sinker moulds you could make one like this. I've used this style for many years
and it works a treat. Easy to use just fill to the size you want and knock it out.
Because it is on a handle no more burnt fingers?

I fill to the top to make winch sinkers about 1.5kg but you can fill about 3 quaters
to make your 32 ounce. I still use a 32 ounce snapper sinker mould for the rods
but you can just fill to what ever size you want.

You have to Drill hole for the line, I drill half way through then turn round and drill
through the other side to stop the drill bit binding up.

Easy to make out of scrap steel.

There is a photo on Fish Wrecked Photos, Couldn't work out how to attach to post.
