Ironwood Hollow Form
Hollow form turning is the pinnacle of traditional woodturning, both in terms of difficulty and results. In this project, I turn a hollow vessel from a piece of ironwood. Ironwood is used to describe a number of wood species, but all of them are dense tropical hardwoods.
The first step is to turn the basic shape of the vessel between centers. Using a bowl gouge, I pare away most of the excess material on the outside of the vessel. I also add a tenon to mount the piece in the chuck.
As with all tropical hardwoods, ironwood will dull your tools quickly. It is imperative to start with sharp tools and to re-sharpen frequently (more than you think is necessary). If you are using carbide tools, make sure you have a fresh insert.
To make this piece easier to hollow, I used a handheld drill to add a depth hole. This isn’t strictly necessary, but it does make the work easier.
The trick to hollow form turning is obtaining an even, consistent wall thickness. The easiest way to accomplish this is by using a pair of outside calipers designed for woodturning. The piece of ironwood used for this project has a couple of defects in it, which actually make it easier to check the thickness.
When it comes to the actual hollowing, there’s no magic to it. I used Easy Wood Tools’ #1 Hollower for most of the work, moving slowly and steadily to avoid blowing through the side walls of the piece. If your piece has small cracks, you can use epoxy or CA glue to fill them in.
Once you’ve finished hollowing, all that’s left is turning off the tenon, sanding, and finishing. I did this by reversing the piece and adding tailstock support to hold the wood steady while I worked.
Hollow form turning is tricky, but straightforward. When in doubt, remember to check your wall thickness often, cut slowly, and sneak up on your desired thickness to avoid blowing out the sides.
Thanks for watching!
Royal Poinciana Lidded Box with Walnut Finial
Turned this on my Harbor Freight 8×12 – 1/3 HP Lathe. It was turned from what was left of a nice Royal Poinciana Log and the walnut finial was a last minute addition. I made sure I could pull off turning the finial before I drilled the hole in the lid.

Colors of the Rainbow
Just finished my first colored bowl. This piece of cherry was very rotten under the bark, but i left this “flaw” on purpose.
Learned a lot for the next time 😉
Thank you for taking the time to watch!
