I have just finished making some blade baits have them EDM wire cut have approx. 70 to 80.
Now I need to make a mold to pour the lead.
Can't use a do it mold since the blade bait is a lot longer then a typical blade bait.
So my question is what is the best material for making a mold so that I can pour my lead.
I already have a pattern for the mold..
need something high temp material ..
need some help
Thanks
