> 3 dayI used this to Bust the glaze on a 68mm bore, in a cast steel barrel of a motorcycle engine. It worked really well - 10 - 30 SAE Oil, 1,500 RPM for a few minutes, left a very smooth set of honing lines. BUT 1: you have to REALLY take time getting th e abrasive out of the barrel after the hone. and 2) I think you may need to run the devices for longer than I did, as the scoring marks were still evident after running in the Bke.

> 3 dayI used this hone on a BMW M20 rebuild out of a mid-80s E30. The hone worked perfectly. I first used the hone with an old 9.6V Makita cordless drill that, sadly, didnt make enough torque to get the job done right. I went out and bought a 6.5 amp Porter Cable 1/2 chuck drill and it cleaned up the cylinders perfectly. Note: if the hone starts to bind a bit, do your best to _not_ stop the drill from spinning. I learned (the hard way) that if the hone stops, and you (in your infinite wisdom, like myself) try to reverse the hone out, the metal braids that hold the hone balls in place will unravel. Youll spend more time than you car too putting the hone back together again (with or without all the kings men). Even though there is still life in the first hone I used, I ordered another one just to have on hand. Thats how much I liked this hone.

> 3 dayUsed this hone on my 4.030” 351W and am very pleased with the results. About 30 seconds in each cylinder with a little motor oil Is all I needed. Worked great.

Greater than one weekUSED THIS FOR AN LS2 AND AN LS3. WORKED GREAT FOR BOTH. Some learning curve, but definitely adjust the crank as you go or you could slightly scuff it like I did. Not enough to cause a major issue, but did need to use 2000 grit sandpaper and wd40 to wet sand. thats user error. not the product.
