> 3 dayI was putting in new rings, but had a glaze on the cylinder bore. this quickly removed the glaze and will allow the new rings to seat properly.

> 3 dayI used this on my 2004 Tacoma when putting in new leaf springs. I needed to clean and grind down a lot of rust on the inside of the shackle that the leaf spring bolt attaches to. This fit, and worked, perfectly! I went a few sizes up on the diameter of the hone versus the hole to be honed so there would be some additional friction and I could get it as smooth as possible. Attached it to my handle held drill and went to town. Would definitely order it again if I needed it!

> 3 dayThis is an easy way to remove a small amount of metal from cylinders. It creates a smooth surface. I would recommend this item to others who wish to enlarge the inside of a cylinder.

Greater than one weekIf 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.

Greater than one weekUsed this for my Predator 212cc go kart build, where I was swapping to a flat top piston for additional compression. While the cylinder didn’t look bad to begin with, this hone made it look great. I coated the hone in oil and utilized it for around 30 seconds per the instructions. Can’t wait to use its again on the next build!

> 3 dayUsed the 3” 240 grit. Did an amazing job on the steel sleeves in this machine for a set of SPI pistons. Compression and performance are still spot on after 800 miles of use. Definitely would recommend.
