Need someone willing to machine 20 cavity's in 2 plates for a total of 40 Will be a half cirlce radius in each plate fora total of 1.0625. Needs to be .001 tolerance. Plates will be 7000 Aluminum that I will supply. .750 x 6 x 6. This will be a 1.0625 ball mold and locating is very important. Need as small a seem as possible. The 2 halves need to be pin located with a .125 hole extending to the top plate of each of the 20 radius cuts in the mold as a pour gate. The bottom plate will have a #55 drill hole .150 deep in the bottom of each hole. No polishing needed just a decent finish cut. Would probably need to have a ball mill made. Can't find any in 1/ 1/16. Anyone intersted please email with quote.
