Looks like I’m the only one up for one of these, been trying to get one made for years, but I seem to be the only one interested in this.
It nice to get a good fitting smooth lead cylinder for tacking an impact cast, I get my best ones with lead wire of bore diameter but lead wire diameters are limited around me.
If I had access to someone with the suitable skills and tools then I could just get blank blocks and have them drilled but in the once heartland of the industrial revolution and the centre of Britain’s heavy engineering industry finding those skills now is very hard.
