CYLINDER ENGINE HONE KIT- 34 to 60 mm Honing Machine with 4 set Honing Stones 120, 180, 220, 320

Mechanically this looks like a decent tool. Unfortunately the 5/16th stones that came with it don't fit in the 1/4" slots in the tool.Edit to say the vender sent the right sized stones for the tool. So other than the nearly four week delay to do the job, I won't complain further.
