MaFeBurnisher BLOG
scraper set up tool

Ok I posted the project, and here are the blog, since there seems to be some wishes for that now…

If there are wishes, I’ll make a work drawing with measures, but I think it’s quite ‘out the road’.
(And thank you, I’m better today, so I could spend a little quality time in the work shop 2×40 min.).

The project comes from different ideas I have seen around, and the fact I’m not all happy for my VERITAS Burnisher, so I decided to try and do better… (There is still room for improvements).

This is where we end, just so you have a clear picture before we get started.
You need of course a scraper, if you do not have one, then you can use an old saw, and cut out a piece.
A file.
A burnisher, or at least a burnisher rod, some say you can use an old hss drill bit, try it!
And some wood, not so important what type (I use a wood from an old bed frame that broke).

Here is the profile of the jig, I call it now 25 (try and figure out why…) .
The truth is that the two spurs on the outside are not needed, they came from a wrong cut I did, but it looks cool…
The profile, has a slice for the card scraper, and a hollow part for the file, these are 90 degrees to each other.
I’ll later get back to the process of sharpening the scraper.

Here I cut of two pieces of wood, which are app. the width of the file by almost the length of the file blade, and app. the height of the scraper.
You need also to make a piece of wood in the dimensions of your file blade, and a little longer.
On the right you see my idea, and primitive sketch.

So a mark up!
Here I think the room for improvement can come… Put it a little higher from the bottom.
The measures of the cut out will need to be a with a little bigger than the file with plus app. two scraper thicknesses (this leaves room for thicker scrapers, and that the wood can move a little), and the height a little more than the file height.
Or in other words the hole needs to fit your file, and the slice needs to be bigger than the scraper.

Here I use my Pushfish to clean up the wood, it was with gray paint!

Now making some thin strip of wood that have to go between the two sides, it need to be a little thicker than the scraper, for this I use my Thin strip jig but there are several ways, please mind your fingers here…
(The only reason I make two small pieces is that I use scrap wood.).

So here are the layout.
And a beautiful classic pipe.

Measure your file – subtract the strip thickness and divide by two, then you can find the depth of the spur for the file.

Now set your table saw, or your Height gauge ,this is starting to look like a commercial for the MaFe tools…

Set your table saw.
And cut the spurs, you can make repetitive cuts, until you have the width.

Time for some glue!

Put a scrap piece of wood in the slice, this will make the slice stay clean of glue, and you can use this piece later.

Clamp it up, and leave to dry.
Remember to put a piece of the slice wood in the top of the slice, so you are sure it will stay open.
(You can see this little piece sticking up).

When the glue are dry, after some wonderful espresso… You can cut the jig clean.

In principal you can stop now!
You have just made a jig for re setting your scraper.
In the back you see the piece of wood from the glue up, I gave it a hole and a string.
A burnisher.
Ohhh – yes and that pipe again Sherlock…

First put the file in the hole, and then use the scraper as you use your gold card! (gentle we have a finance crisis now).

When you take out the file you have an extra hand for holding the card scraper.
Burnish away!

Or follow the next steps for improvements!

First it’s time to drill a hole.
Yes the scraper could slip out when burnished.

So I decided to add a stop, nothing fancy, just a dowel in a string so it will not get lost.

Now it’s time to make a fixed burnisher angel set up.
So find a drill bit the same size as your burnisher.

Find the angel you prefer, I choose 10 degree.
(According to this article by Christopher Schwarz (a big icon on my wooden sky), there is no big difference if you set it at 5-15, the burnish process are the important).
What you want now is to find the point very precise where you want to drill the hole.
I choose to say that the burnisher should stick app. 1 mm up in the slice, and then I will put the wood stick under when using. (The truth is that I did not have enough room under the file to drill through, so this could be an improvement for you to make).

Here a close up of the marking.
On top you see a tiny mark of the center, this is where your drill bit shall center.

Setting up my drill press. (Oh my the guy is digital!).

Now tilting the table 10,1 degree.
(The zero one are the artist in me!).

Drill a leading hole with a small drill bit.
You can see the marking up here.

Then the full size.

Now you can stick that burnisher through the hole.
And time to use the gold card!

So the process of sharpening.

First you mount the file, and run the scraper through, don’t use to much pressure, just enough to gently file the old bur away.

Now lay your scraper on the jig, and run your burnisher over with a slight angel down, and a pressure like pressing an old fashion door bell. Do this on all sides you want burnished.

If you prefer the freestyle way, then make your bur now like this.
Remember to mount the little dowel to keep the scraper from sliding out.

Or if you want it to be fixed, the burnisher is mounted in the hole, and you run that gold card, with the pressure of the old fashion doorbell.
(My good that pipe seems to be following me today).

And here are the MaFeBurnisher set.

And just to finish of a naughty 25 picture!

UPDATES! 4 october 2010
After the comments today, I decided to go and make a few updates, to make myself and some of you happy!

Oh my I forgot the oil and grease up phase! I use my favorite grease box that now has become a natural part of my tool collection (and yes another espresso latte).

Drilling some holes on the one side, and glue in three rare earth magnets with epoxy!

Now the jig can be placed on the sharpening stone also…

And the card scraper can be held firmly 90 degrees, as you make that gold card moves.
This acually works really well, so well that I was quite surprised.
You need very little energy to pull it, but it’s allmost impossible to get it of the jig from vertical.

A second solution can be that you make wooden honing stick.
You simply cut a slice of sandpaper, here I use grade 360.

Spay with glue on the back of the paper (or how you want to apply it).

Mount on your wooden stick.

Put the stick in the hole, and you are ready to hone a finer edge before you burnish.
(It’s a matter of choice, and temper).

And now the card scraper can hang on the side on your wall, using the rare earth magnets to hold it.

Thats it for now…

Hope it can bring some scrapers to life,

Best of thoughts,

Yes life is sure grand! MaFe tools for free – I’ll sure get rich!
Steve, yes so I learned new to need!
If you want a fine hone, buy a EZE-LAP DIAMOND and stick in the file hole.

You know. I’m not terribly fond of the veritas variable burnisher that I have either. I have usually just done drawn and rolled the edge by hand. The thing that you have done that can be so handy about this jig is that it will make it extremely easy to get a good square edge on the scraper before honing and burnishing. Well done sir. You need to be patenting these jigs and selling them to the tool manufacturers.

Mads, nice job and well explained.

By the way, did you quit smoking? Your pipe looks always emply and clean? Perhaps the tobacco can is empty too?

I like the use of the digital angle gauge to set the drill press table at the appropriate angle.

As I can see here, no need to buy a sophisticated jig to help burnishing cabinet scrapers. Thanks for sharing.

I simply love your sense of humor! Great descriptions along the way…Thanks for sharing!

Just curious as to what kind of file you are using? A single cut? Double?

Nice job, I like the integrated area for the file. I did a simple jig from an woodsmith shop tip, but it was just the burnisher. Looks like I’ve got a new project to do before I can get back to my turning. :-)

Seems I have yet one more MaFe tool to make when I can find the free time…. I’ve three scrapers that are calling out to me for sharpening and this is just the ticket for that honest right angle hone.

Thanks once more for a well put together blog, great pictures and description! Glad you’re feeling a bit better today and hope you can get that pipe filled… :-)

As always, Mads, this is a very good blog post. You are a very creative and ingenious man. I’m sorry, but I didn’t know you had been ill. I hope you get back to normal soon. Thanks for posting.
