Where can I get a tool for scraping?

- Rod White

McMaster Carr has tubular construction hand scrapers for sale inexpensively. Carbide or HSS. I would do that.

Get yourself a worn out file, and grind the end to shape.

NO. I made thousands of strokes on... popcan alloy was it? Before resharpening. Amazingly I seem to be able to go for much longer on steel!

Oh, the scraper is the tang end of a small bastard file. But the tang got broken off so it's the nominal width of the file. I ground a radius with the Dremel and honed an edge with a diamond stone.

This might work with aluminum. Apparently most modern files are case hard, so grinding the end into a scraper (was a common procedure) may no longer give good results.

It broke, and at a rather high force as I recall... yeah I think the broken end will work fine. ;-)

Of course, if anyone else wants to do it this way, yes I'd recommend using the nose end instead. Grind off a few inches of teeth on a fat, dead bastard, get a light radius on the end and go for it.

I have a couple of tools for scraping. One is made from a worn out file about ten inches long. The file teeth were ground off at the end of the file. The end has a slight radius on it ( done free hand ) and the end is ground with about an 85 degree edge.

The other one is a piece of scrap steel that has a carbide insert silver soldered to it. I used an insert with a positive rack.

Try a bearing scraper

Robert:

The tool seems to be less important than how it is ground & sharpened. You're not specific as to what "small" means. The scraper I use most of the time is > 1" wide, giving more edge to use up before the next sharpening. I found that the longer tools with a bit of flex, just a bit, worked better. I made my own, large, handle or knob for my favorite scraper. And I do have my favorite. It uses the HSS inserts for the Anderson Bros. scrapers. Enco makes knock-offs that work just as well, and are far less expensive.

Properly forging a spent file is something I'd rather not spend time doing. Best of luck. Also, Michael Morgan's video on scraping will tell you more in

Cheap screwdriver, cut off tip to leave cylindrical end, turn down and thread to 1/4-20. Now you can attach triangular carbide inserts.

Or you can buy this for less than $10 (with insert) in the tile tools at Lowes.

Home Depot used to have a Sandvik version of this in their tile tools.

Werner also makes a cool paint scraper with a 2.5" flat carbide blade at Lowes.

I've been taking the replacement Werner blades, snapping them in pieces, and brazing them to 1x5x0.125 steel strips, and fastening those to 1/2" EMT conduit, to make a carbide tool for precision scraping. Less than $10 and works like the $100 Dapra item. This does require a tool grinder with diamond or green wheel to reform the sharp edge to blunt.

You already have the chisel. That should be of a suitable material if you re-grind it to the right shape.

Mmm. Perhaps I should have specified. All my worn-out files are even older than I am, so...
