What is the fastest way to get angle grinder marks and file scratches with sandpaper
Angle grinder marks should be all removed with a file . Then you start with sand paper 150 gr should remove all file marks then you keep moving up in grits till you get were you want.
When you change grits you should sand your blade on a different angle each time till you get to the last Grit then sand the length of your blade and the final ones should should be just straight pulls.
Get good metal sand paper and use a lube with your paper . Lots of different ones oil wd 40 windex simple green .
I use window wash mixed with simple green. And use a hard backing with your sand paper . 3/8 G10 or 3/8 aluminum I use 1/4 steel plate that I made for hand sanding. Have fun.
There is no fast way. Hand sanding takes time. The method Kevin describes above is pretty much the way to go.
Sheer will, determination and sweat...and what the two fine gents above said!
I painfully go through all the grits using cutting oil, 120 220 320 400 600 1500 2000. I have small pieces of wengue I use as blocks, and a large piece of wood with a piece of leather stuck to it that helps conform to the blade. I'm a noobie but have experience in fiberglass and epoxy for boats and motorcycle fairings. Done my share of bodywork but I really don't like it.
These days I never go pass 800 and most of the time I'll go up to 800 then back down to a 600 for a final finish . I fine it better that way.
Gough Customs has a good video on his site that shows how to do a satin finish that is similar to what Kevin Cox is doing. He goes up to an 800 grit then down to 600 for final finish. Its worth checking out. Its helped me with my knives.
seen you say that in a earlier post and tried it, works great with the step back to the 600 in straight pulls like you said, turns out nice, thanks for the tip
