Just curious if there is any problem with lapping my coticule with the Norton Lap that came with my 4k-8k set?
Or is there a preferred method specifically for the coticule?
Thanks,
Marc

By all means, give it a try - I did. But i found the coticule to be much harder than the norton lap plate, and have actually stopped using it all together as I found it constantly needed lapping itself when used with the stones i own (nortons and coticule).
Personally, i would suggest getting some good quality sandpaper of a fairly rough grit and working it on a flat surface. Then finishing up with a finer grit paper.

Norton doesn't recommend their lapping plate for anything but their waterstones. I'd try a DMT D8C if I were you.
Give it a try, have you got a straightedge ? The only trouble with the norton lapping plate is they wear. Lap the coticule with a pencil grid and try a straight edge on it. If there is a problem see this tutorial here if you haven't already. I use a DMT D8C but sandpaper works too.
Another vote for D8C--it's a pretty versatile plate anyway since you can also use it for resto work. Pencil grid, lap, chamfer edges w/ wet/dry paper. You shouldn't have to lap it again for a very long time.
You can also try raising slurry more from the corners--more even wear & less need to lap.
