Re: Specific questions re using a boring bar (Old school)
It all depends on how much the bar flexes...the first Storm bar i ran you had to go very easy on last cut...nowdays i can do it single pass and end up dead on.
I would go 25/3/1 measuring after the 25 and 3 cut to be able to land within 1 for less honing...you donīt want a rough surface or to much material left to hone...and you donīt want to overbore !!!
A heavy cut will give you taper if the bar flex or is loosely adjusted/worn.
When you have got to know your boringbar you should be able to end up withing 1/2thou.
Get a positive small radius finishcut K insert for the cutter preferably coated.
