Boring tapered hole
#18
I am sorry I don't know what machinery you have to work with.

 I have made some chambering reamers using HSS drill blanks..I keep them in stock from 1/4 inch to 3/4 inch dia and 6 inch long.. Grind them to correct size/taper with surface grinder using H-46 grinding wheel......Then cut 4 flutes with a carbide endmill - take it to full depth on each flute with a single pass and it works well. Then relieve the edges with a die grinder. Finish with a diamond hone. Works very well. Nothing difficult , take your time to do it right.
