I make no claim to be a “real” galoot with the card scraper, but this process to renew the burr has worked for me.

After a lot of use, the burr will get mangled and need to be created afresh. I start by setting up the scraper in a make shift jig using the bench vise and a couple scrap blocks of identical thickness. I set the scraper just above the blocks using a feeler gauge to get uniform height exposed.

Then I file the old burr off with a mill file, using the jig to keep the file square.

Then I go to the granite surface plate and stone out the rough filed surface, using the side face to keep the stone square (note: I keep the granite plate set up for scary sharp sharpening).

Next, I remove any small burrs residual from the filing.

And inspect the edge to see if it’s smoothe and square.

I made a burnishing tool by putting the shank of a broken solid carbide router bit into an old screw driver handle.

Burnishing the new burr is just swiping the tool across the edge at ~ 20 deg. angle

When your all done, you want the scraper to make shavings and not saw dust.

After some use, I use the burnisher to renew the burr. This can be done several times, until you have to start all over.

Not a first class setup, but it gets the job done pretty well.

Interesting post, I am not sure what your inteperation of “galoot” is, but what is your opinion as to the finish produced by a scraper is when compared to the grit system?

Its obviously in the 1000 Grit or higher?

Rob, as I understand it, the term galoot refers to someone who prefers to use hand tools and shuns power tools.

I certainly think that you can get, in the right hands, an excellent finish with a scraper. But my hands are not the right hands. So I don’t use the scraper for final finish. I only use it to clean up the dried glue in prep for sanding.

One problem I have is that the slope of the grain is not the same from board to board in my glue ups, so regardless which direction I scrape, I’m always going “up hill” on some boards.

OK I found it to be:

Simple Definition of galoot : a man or boy; especially : one who is foolish or awkward
Which I thought was very strange thing to say, hence the question
Glad to hear a different and more related meaning
The humble scraper is a tool I could not work without, or if I had to results would be less professional.

Also how do you prevent your tools floating away?

I struggle to get a clean, straight edge on my scraper. Your method looks like just what I need. I think I’ll also work on a similar 45º setup for my #80 blades.

Thanks!
