I have good luck sharpening scrapers with file, honing stone,and burnish. But recently I witnessed Mark Adams do just a file and then burnish. No honing stone involved in his sharpening process. His scraper worked perfect. I have tried to duplicate with the same file he recommends. No success. What am I doing wrong?
Thanks

Sorry for the late post.. I have a 'GOOD' Mill file.. I just pass on the file when I think it not working right.. I hardly ever burnish unless it is really figured/bad grain wood!
I haven't seen the video but I use a lot of files. He is probably using a single cut SMOOTH mill file and "draw filing" which is holding the file perpendicular to the edge (90 deg) and drawing it over the edge. Done correctly, it produces a very fine finish.
Veritas has a jig which holds a small file and another which holds a small round carbide burnishing tool, for a 2 step process.Regards, Scooter"I may be drunk, but you're crazy, and I'll be sober tomorrow." WC Fields, "Its a Gift" 1934
I haven't seen Mr. Adams Sharpen his scraper,but I absolutely cannot achieve the same results from filing only.I started out just filing and burnishing. The results I get from using water stones have made a world of difference to me.The shavings that come off the scraper are tissue thin and clean.I even sounds different.I use a block of wood to help me keep the scraper vertical when honing the edge,keeping it at 90' is key.It takes time at first , but the edges are polished and crisp before I use the burnisher.A polished, lightly oiled burnisher(not a screwdriver) turn the edge with ease.
Remember, what works for me may not work for the next person.Just best to experiment and find your comfort level.
Guess I'm a hillbilly. I only file, no hone, then use a screwdriver to turn the bur. Works for me. Honing and and a real burnisher may work better, I don't know, never had the need to find out.
I agree with you, Steve. I was "overthinking" my scraper sharpening for a long time until I read the simple way to do it effectively on another forum.
Hi Ed,
Was your name formerly Ed from Mississippi?

Yep. Pretty good odds that I'll be "Ed From Pensacola" by next spring, damn the hurricanes, full speed ahead!...take care.
Hi all:
Here's what I do
I use a fine single cut mill file
I file the card edge using the whole file to make sure the card edge is flat.
Then I draw file to give a nice surface finish.
Burnish the flats first then at a lite angle off the edge like 5°
My burnisher is a valve out of a automobile engine. I just use the stem. This has worked great for years.
If the wood is highly figured or has a real grain problem I will run the card edge over a 800 grit oil stone (with oil) then burnish as above.
I know it's quick down and dirty but hey it works. If you do a good job of draw filing then the finish is that of a 400ish grit stone. Burnishing the flat raises the burr to the edge and then burnishing to card edge creats a nice smooth hook that cuts smooth and clean. But if you just burnish the card edge the finish will not be as smooth.
take care
