Recently I made a small hollow form, using my Mini Easy Finisher to do the hollowing. But with only 4 inches of bar, I couldn’t hollow very deep. I started looking for a new hollowing tool, but they are all around $100.
While browsing YouTube for turning videos, I ran across some videos by Cap’n Eddie Castelin (Blackhawk Tools & Big Guy Productions). They showed how to make a hollowing tool that only costs a few dollars to make.
I already have the three mini tools from Easy Wood Tools: The Mini Easy Rougher, Mini Easy Finisher, and the Mini Easy Detailer. I like them a lot.
Seeing Cap’n Eddie’s videos inspired me to make my own. I knew that I wanted it fairly long. Therefore, it needed to be pretty hefty. I settled on a piece of 1/2″ square hot rolled steel bar stock. A 48″ piece was about $8.00. I decided to cut it into 3 – 16″ pieces.
I ground the tip down and shaped it for the carbide cutter. These I got from Cap’n Eddie on his Products and Services page. I ordered the 3 pack of the 12 mm round cutters for $24. I drilled and tapped it for the 6-32 machine screw.
Here’s a shot of the cutter installed:
I also ground the tang round to better fit the handle:
Now the handle. I found a piece of ash on the firewood pile, and decided to give it a go. I mounted it on my bigger Jet lathe in the shop.
I roughed it down
and cut it just above a big knot.
Then I moved it to my Rikon lathe in the studio.
For the ferrule, I used a 3/4″ steel conduit coupler, cut in half. It has a set screw, so I can use this handle for multiple tools, simply loosen the set screw and remove the tool.
Here it is almost finished:
And the finished handle with the tool.
All put together.
All told, this tool cost me about $11 to make. Not bad.
