> 3 dayIf you are only a tiny bit over the nominal size do not follow the instructions and go up one size. They are oversized to begin with (my 1 1/8 hone being a few thousandths shy of 1 1/4). I bought a 1 1/8 hone to remove the seam from 1 SCH40 pipe and open it up from 1.03 to 1.06 so that 3/4 pipe will telescope in structural applications. I also intended to use it to open up 25mm aluminum C-cell flashlight tubes to fit 26mm LiFePO4 cells (1.026). I am hoping that after breaking in the hone on the steel pipe I will be able to start it in the aluminum tube without damaging the end. I think in both cases I would have been better served in not following the instructions and buying the 1 hone instead.

> 3 dayPurchased 76mm for honing an old ATV cylinder. Some WD40 and several passes later the bore is cleaned up and has a nice surface for the new piston rings to seal in. Cleanup is easy with carb or brake cleaner. Make sure to get the right size hone for your bore!

> 3 dayExactly what you need to prep a new Nikasil cylinder for new rings. This will remove material quickly, which is what you need to set in a nice hash pattern in Nikasil. However, you only need a slow speed (low gear on most drills) and only 3 or 4 oscillating strokes. Good luck.
