I like to push the manufacturing process to the extreme. My friend Gabriel Beaulieu makes african djembe as a part time job so he is a real pro with the wood lathe. We were thinking of new ways to use this great tool and came up with this complexe shape :






Step 1: The idea

Picture of The idea
Everything seems a lot more simple on paper, so we didn't worry much about our chances of success. àThe idea was to glue a lot of scrap wood together, turn it in the shape of sn apple heart. Then cut it in four parts. Flipping each part 180 degrees so a cavity is formed in the middle. Finally turn the part again to give it a nice and round shape... here is how it went :

Next time you want to split a turning into quarters glue it up but put newspaper between the bits of wood where the divisions are going to be. Then the turning will split along the paper with a gentle blow or two from a chisel.

Szturc, you are absolutely right. This works perfectly. Care needs to be taken but it works just fine.

Nice work. Next time you want to try inside out turning (as this is called) instead of gluing the blocks together, tape them over completely with painters tape, then recover the mess with duct tape near the ends. This will hold everything together and you will get a nice shape. Then before removing the tape and turning the blocks, sand, seal, and finish the inside first. It is too difficult after they have been turned inside. That is the method I use and it works beautifully.

I love the finished product. Very nice.

Good project, Samuel! I'd like to do one of these in a smaller version as a Christmas ornament.

What are the measurements I would like to make one
This is called inside out turning. If you cut your wood into 4 sections to start then reglue them putting 2 layers of newspaper in between each section using white or carpenters glue it is strong enough to turn but comes apart at the seam relatively easily. Turn inside out and glue permanently, no newspaper and carpenters glue, then turn the outside.

Awesome idea I'm thinking about making a small scale one in a teardrop shape as a pendant.
Gorgeous!

I dont mean to be a jerk but it looks just like jou copied an article out of wood turning magazine.

Haha, woodturning magazine? Really? I never heard of that, but thanks. I guess it means I made a nice work. I did this project in 2008 for the competition « Le Bois au Naturel» in Victoriaville, Québec.. But I would like to see this article. Maybe they copied me! ;)
its a 2005 magazine ill snd you a copy of it

outstanding… but, as you said, downright dangerous ! … 
did you think of a safer way for the same result or did you leave it at that ?…

A good cdc could do it... But it is no fun.
absolutely !

when glueing the square blank together...
stick a piece of paper in between t he 4 quarter sections(where you'll later split, and reverse). Brown paper bags seem to work the best for me.
A sharp chisel will then split along the paper very nicely, and easily. No broken blades required.

For the one person who is sure to ask... do NOT use paper between the sections when glueing back together for the hollow-form turning.

Glad no one was hurt when it broke, as you were turning.
Which type of turning tool did you use for the final shaping? a gouge?


It's kinda funny, I JUST saw this technique demonstrated on one of the PBS woodworking shows(roughcut woodworking, I THINK. not sure though). Great to see it's not just the "professionals" that can turn out a great piece..
great craftsmanship!!
