Hi,

I have a job to do on my lathe, which involves making (for a start) 10 mild steel cones with a shaped side.The end product is like a laboratory stand, but much better looking, being finished in dark chrome.

Anyway, the base has an 8mm vertical rod and the ones that were made before (not by me) have the rod welded into a hole in the base. This makes preparation for chroming a nightmare where the rod is inserted. So my design has a cone brazed onto the rod and then tapped M6 to screw the two pieces together from underneath.

I wish to turn a curve into the cone and so I am thinking of grinding a tool from a 3/4 sq HSS blank

My query is - will I get away with a zero degree rake on the cutter ?

Cheers,

Rob
