119 forum posts 8 photos	I don't know if I have just re-invented the wheel or come up with an idea that others might not have thought of. I needed to make a number of 16mm balls in brass and doubted my skills on a grinder to make a good job of the form tool. In the end I got a flat piece of tool steel and simply cut a half-circle in it of the right diameter, using a solid carbide end mill. This worked very well. The end mill was not a high-end specification one, it was a low cost item from Jenny at JB Cutting Tools (usual disclaimer) Chas

119 forum posts 8 photos	I just placed a small piece of scrap under the front of the toolbit to raise the front and provide what looked like a suitable amount of rake. To the best of my knowledge the exact rake is not critical in this application. I used a spray can of WD40 to lubricate and cool the work in progress. Regards,Chas
