On sharpening scrapers, how many burnishings do you think one can do before going through the whole process?

Good vid. I learnt 1 new idea burnish at 90 deg BEFORE putting on hook.Thanks Todd. Other than that I use a LV carbide burnisher for the 5 -7 deg hook. |

I was never good at sharpening scrapers.... must try Link's techniques soon. As for the hollow ground chisel... old toolmakers trick. I get that one. |

Addendum: I usually go right to the burnisher from the file. Of course I knock off the burr from the filing but if one chalks the file and gets a nice clean stroke the surface a good sharp file leaves is very good. This simplifies the whole process. It is easy to round the edge when trying to refine it on a stone even with a block of wood to guide you. You can feel when you get a good clean cut off of the file and you can feel when you roll up some metal and spoil the edge. If I was going to scrape a finish or try to get a final surface with a scraper I would refine the edge on a stone and make a small burr but for most work this isn't necessary. There are other things like using the burnisher to take the hook off and then put it back on to work harden the edge but this video was very extemporaneous and only basics were covered. Hopefully enough to give the idea. L. |

good point about not trying to get too much of a hook; i lay my burnisher over too steeply i think |

Slap an old 80 grit belt for metal on the 6 incher, flatten the faces, square up the edges and burnish. An arch top build...usually about 3 sharpenings. Do them all at once. Less than 1/2 min per scraper. Ya, me know, me slowing down in me old age.  @ Danny V~ Once. |

I am usually a bit quicker with sharpening my scraper, and I get a pretty decent hook, though I'm not always happy with the consistency and how long it lasts. I have sharpened it by hand for years with the fine side of a regular file, with the scraper in a bench vise. Then to put a hook on it I usually just grab a screwdriver and use the shaft at an angle similar to the one in the video. I've found this gives me a very nice edge about 80% of the time, but only takes around a minute to do both long edges. I think I'll try a few of the tweaks in here and see if it helps. Nice video, very clear instructions. |

Thanks for the video & the addendum. I'm glad to hear that it's easy to round the edge on the stone - something I've always had issues with and thought I was the only one. Kevin Looker |

More great woodworking advice from Link. I remember when we first got together and I knew I could make a decent instrument. But he has taken my skills to another level. |
