I apologize. In my pic of abrasives above, scotch brite(which comes in 8x12" sheets) is upper right, strips of sandpaper(in 240 and 500 grit) are below. The gray one some here might call emory cloth.Thanks guys.
Your terminology for scotch brite is a bit different to mine down under.
The strip mentioned above is know as emery cloth to me.
Scotch brite is a wheel or disc.
Cheers,Chris.
I wouldn't do anything if there's no transfer. After I'm done porting a cylinder I do run a 2" scotchbrite drum through the bore a few times to help polish port edgesTalking about cylinders with medium to light scratching,with no transfer.
More a final finish.
Cheers,Chris.
As in my top pic?I wouldn't do anything if there's no transfer. After I'm done porting a cylinder I do run a 2" scotchbrite drum through the bore a few times to help polish port edges
Yours is what I'd call a 60 grit flap wheel drum. It would knock off any any high spots left next to scratches in the plating. I wouldn't try removing enough material so that the scratches were gone. It would also work for adding a slight crosshatch to the cylinder wall, which may help break in the rings. Not sure the latter is necessary though.As in my top pic?
