I bought the mold frm a secondhand shop (Pawn shop) (I am a pawn-shop junkie besides a Lure junkie - sound terrible)
Its a alumimium mold , of which guys have their molds casted at foundries. They cast metal castings. The most common metals processed are aluminum & cast Iron.
I must say there are many guys who also sell molds , the size is the only thing. Try Google SA , Gumtree & even SL's, but you pay more for n new mold than the one in the Pawn shop.
Sorry for confusion - I use the abbreviation ff. when I refer or say " the following"....or "for the following"
Try your Scrap metal dealers for WM & then melt it down to sift the impurities from it & you will be left with a bit better quality WM.
I bought for +-R50/Kg in Durban.
If you do a search on SL using words White metal suppliers , you might find info, as I remember that Bennie Jordaan posted a while back wrt a supplier in GP area.
Happy hunting & making lures.
