Removing file marks from frets

I was wondering what everyone’s processes are for fret level, crown and polish are. I use a a levelling file followed by a long levelling beam with 240 and 400 grade for levelling. Then a triangular crowning file for crowning, obviously, and a small, fine file for fret ends. I use a few grades of wet and dry for smoothing the crowning over but I still get a few tool (crowning file) marks left on the sides of the frets. 

Do you guys have any good tips/processes for eliminating this problem?

 

Thanks in advance, I’m grateful for any help you can offer.

But will read with interest the suggestions of others ...

I basically use the same technique Mark uses on the course of different grits of sandpaper using a fret file. I use one of these.

I then us A fret end file and finish with wire  wool. I have been known to use a polishing wheel on a Dremel with some Autosol metal polish..

Mark’s process uses crowning files, 150 and 300 grit followed by wet and dry round an old crowning file - then polishing with wire wool and synthetic wire wool.....

Following this set of steps my frets are smooth and shiny....

I level the frets with a long piece of 18 mm mdf with a strip of 320 grit or 400 grit, depending on the amount of leveling that needs to be done. I take of the sharp corners with a small fret end file and for crowning I use a concave crowning file (Hosco). I use the same crowing file with a piece of 400 grit to remove the file marks and 600, 800 and 1000 grit to remove the scratches of the previous grits. Then a nice polish with 0000 wire wool and some polishing compound. Shiney!!!!!

Pretty much the method I learned with Mark....

Measure once, cut straight away and maybe you're lucky......

I level frets with a chunk from a 1m aluminium level - the bubbles had vanished and I was going to chuck it but my straight edge showed that it was very flat so I chopped the ends off and tidied - I have two 18” long flat edges about an inch wide so can have two different grades of paper attached - also use a long aluminium radius block.
