Exclusive Video: Sharpen a Card Scraper
Added 2023-09-27 13:44:04 +0000 UTCFriends:
Did you buy a card scraper to support the Patron Scholarship? Awesome!
Now what?
In today's exclusive video, I'll show you a variety of techniques for getting that scraper to take fine shavings and leave a silky surface on your work. I go nice and slow and show each step in detail. Whether or not you've bought one of our limited edition scrapers, you'll probably get a few good tips from this video.
We've got one more week to raise money for the Scholarship and then I'll be back to tell you how to apply.
We'll also have a regular video on Saturday.
My family has ice-cream on Wednesdays, so I'm totally pumped about that.

It would be nice to see what the scraper's edge looks like under a microscope. Is the burr at right edges to the blade?

2023-09-29 17:48:43 +0000 UTCOh! how would I know if it is hard enough. I have used it for many years and it still works so how do I fine out?

2023-09-28 11:42:38 +0000 UTCI have a variety of scrapers, some of which are pretty hard. I use a carbide burnisher. They are available at Lee Valley. I got a carbide rod from AliExpress and fitted a handle. It works great. Other sources of cheap carbide round stock include busted end mills (if you know a machinist), dulled solid carbide router bits, and dulled carbide die grinder bits.

2023-09-27 23:12:34 +0000 UTCIt does! That's everything we've accomplished so far. It's a good start.
Rex Krueger
2023-09-27 21:04:37 +0000 UTCThey often work well, but they're not all the same, so some of them are hard enough and some are too soft.
Rex Krueger
2023-09-27 21:04:14 +0000 UTCI'm afraid not. "Cold rolled" isn't the same as hardened. You need something hardened. Sometimes a screwdriver handle is enough....but not for the Compass Rose Card Scrapers. They're too hard.

2023-09-27 21:03:46 +0000 UTCI always sharpen both sides. The video was already pretty long, so I didn't show both.
Rex Krueger
2023-09-27 21:02:28 +0000 UTCYou totally can...but I never have, so I don't think the risk is so great.
Rex Krueger
2023-09-27 21:02:05 +0000 UTCI think that's a great idea! I think I'll try it.

2023-09-27 21:01:46 +0000 UTCIf I may ask, does the $1115 contain people who have upped their patron tier?

2023-09-27 18:26:07 +0000 UTCThanks that helps a lot and could one use a knife sharpener rod for a burnisher?
Carlos Alvarado
2023-09-27 17:58:58 +0000 UTCNice. I made my own burnisher with 1/4" cold rolled steel rod (sku 2279389 at Menards). Is that hard enough or no?

2023-09-27 17:13:02 +0000 UTCGreat video. I've watched so many on sharpening card scrapers and usually end up more confused than before watching. Question: do you sharpen both sides of the scraper or just one as you showed?
Amy Holderness
2023-09-27 17:12:26 +0000 UTCWow - that looks like you can get a nasty gash on your hand if not very careful.
Rick Prosser
2023-09-27 16:46:01 +0000 UTCGreat tutorial! I was always taught to slightly round over the corners of the card scraper when filing so as not for the corners to dig in to the wood while scraping. When I say round over I mean slightly file on a different micro-plane surface the corners from the cutting edge so as the corners will not dig into your wood stock. What is your opinion on this technique?
