I needed a larger lathe chisel to try my hand at turning bowls but I didn't want to spend a hundred dollars on an experiment so I decided to try and make my own.

Step 1: Getting the Parts

The following is a list of the parts I used:

Shaper blades - I used 1" radius carbide blades. I got a set of three for less than $10

A 18" 3/8" square tubing at the big box hardware store. A got a piece 3' long for about $5.

A number 12 bolt, split washer and nut.

A piece of 2x2 for the handle.

Glue - I used liquid nails because I had some laying around. Epoxy would probably be better.

A rivet, should be able to find one for a few cents.

Total cost for one chisel about $7

Step 2: Cut the Tube to Length

I cut the tube in half to 18" and saved the other half for a future chisel.

Step 3: Drill Hole to Mount Blade

Step 4: Mount the Blade

After the hole is drilled bolt the blade to the tube. I set the blade about 2/3s of the way on to the tube. Then cut any excess bolt away.

Step 5: Carve the Handle

I actually used my new tool to turn the handle. Use your imagination to shape it to best fit your turning. I cut the 2x2 about a foot long. I based that size on the fact that that was as long as I could feed through my band saw.

Step 6: Drill the Handle

Now you need to drill the handle to accept the tubing. I just clamped the handle in my vise and drilled it with a hand drill. Pick a bit the will create a snug fit. Too loose and you may have trouble getting it tight. Too small and you may break the handle when inserting the tube. I used a 5/8" bit and it seemed to be about right.

Step 7: Insert the Tube

Now apply glue liberally on the tube and insert it in to the handle. I also drilled and inserted a rivet through the handle and tube to make sure that it won't turn.

Step 8: Done!

That's pretty much it. Allow the glue to dry and go out and use it.
Couldn't you cut it diagonally from the corners to potentially create four?
Thanks rimar. I'll check out the videos.
Hi nice article I make all my tools from old files they are excellent.
awesome :)
Good work, I agree with BARKing. Maybe you could understand this video, although it is spoken in spanish: <a href="http://www.youtube.com/watch?v=SLlXP1OgeUw" rel="nofollow">http://www.youtube.com/watch?v=SLlXP1OgeUw</a> (don't use automatic subtitles, they are comical). This guy uses a <a href="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcTigtWen6w4w2t1N25Coedz1rzgnjgyN6ZAENJbZ8qd5Vi6xkDE" rel="nofollow">spine key</a> (I don't know its English name)<br> <br> Or also this other: <a href="http://www.youtube.com/watch?v=tSykpyt7NWA" rel="nofollow">http://www.youtube.com/watch?v=tSykpyt7NWA</a>, made with a piston pin.<br> <br> I made both, with very good success, but I shaped them like a woman nail, cutting them obliquely. They cut very well.&nbsp;<br>
Thanks. And yes it is probably a scraper but it works a lot like a spindlemaster which I believe is kind of a hybrid. But I'm new enough to turning that I don't really have a technic. :)
Good job. You should note that you made a scraper tool and not a cutting tool, because there are different techniques used in turning. <br>90% of what I do is cutting but there are some places where scraping is better.
