10-4 good buddy I'll definetely pass my 400 grit flex hone through it then
. I know you do this for a living too cindys_sn95 I just can't figure out why the machine shops I've been to locally keep telling me to go with a 280?
About how long do you think I should pass the hone through it when I get it back? Last time with the 351w I did 3 passes in each bore and kept the hone in for about 20-30 seconds each time. I looked up this video on youtube
and did my best to copy the motion demonstrated in it. I'm using a black and decker drill that has a max of 1500rpm and I keep the trigger a little above half throttle. Video says not to exceed 1200rpm so I figured I was doing it right.
One thing I did do wrong though it didn't seem to hurt was I started the hone spinning inside the bore instead of before inserting it but I did keep it spinning as I took it out though. I think since the hone was a tight fit I was afraid to go in too fast(giggity) but now that I watch that video again I think I should have. Is it really important to have the hone spinning before inserting it into the bore? Thanks again cindys_sn95 your a tremendous help as always
