However if somebody is dead set on going to someone that only has conventional turning capabilities then the SFM on the taper needs to be run to the largest diameter. Also in my opinion that box tool in the pics you put up is absolutely the worst way to cut a taper because of the heat it generates, a taper attachment with a single point tool and a large radius would be the way to go. And only removing .010 -.015 a side max per pass.
i agree and the pencil sharpener tool was a upgrade 10 years ago! its what they use today.
