Jon, have you tried your boring bar for making facing cuts? It seems to me that the boring bar cutter geometry would also work for facing cuts, or am I mistaken?

Hi Jon,

Thanks for sharing your design of boring bar. I particularly like the simple ground profile enabling the cutting edge to be kept very sharp. I can see myself making something similar for the finishing cuts to cylinder bores.

Hi All, this is the first post of a long term browser. I'm a novice machinist with an inherited Cowells lathe and still on the lower slopes of a steep learning curve. I'm currently machining some 0 Morse centres from silver steel and was having some trouble getting a decent surface finish. I saw this thread and thought I'd give a vertical shear tool a go. The results were great and being sure of getting both surface finish and dimension right when I make a cut is a real confidence booster. So thanks to all and particularly the American guy who went to the trouble of making the videos.
