I have looked at other spiral shells but was never able to work out how they were made. With the New Year and a fair bit of fire wood created I have finally got a couple I can show off. Much like a bowl from a board method but cutting the board into wedges before attacking with the scroll saw. Pic 5 and 6 are the shells after sanding and before the paint attack. These are a start and hopefully with a bit more experimenting with the angles the next one I post will be bigger and complete with stand. The 2 are 5” tall and 6” long..

Geez Bob, They are awesome. Bet it took you at least 2 minutes to make each one. LOL
You never cease to amaze me with your projects.
Thanks for showing.

-- Bob, Western Australia, The Sun came up this morning, what a great start to the day. Now it's up to me to make it even better. I've cut this piece of wood 4 times and it's still too damn short.

That looks great. Would like to see how you made them. Perhaps photos and explanation in a blog?

All of us are caught up in the shape of the sea shell. Especially this shape. You have done a great job and I look forward to seeing more. Maybe a step by step too

Wholly Cow Bob!
That is out of this world! You should experiment with making smaller ones and get yourself a few hermit crabs. I can only imagine the strange little boxes or starships they would be carrying around/living in!!

No really these are fantastic!!

Bob sent me a pm a short while ago saying he wouldn’t be posting much this year as he had run out of ideas, I told him to stop whining, get of your ar.e & get to work.
Well my friend you sure have come back with a hiss & a roar, this is a fabulous project & I’m sure still in the prototype stage.
cheersd mate

Bob, you have arrived in 2014 running at breakneck speed. I love the Colour Coordination and the sea shell appearance, there is also at first glance the image of a coiled snake. Combination of Death Adder and Carpet Snake. They both have beautiful markings like your Spiral Shells. Congratulations, I would not know where to start on that project??
Do you piece together your timber and then hollow out like turning a bowl, and then go to the scroll saw? It would be beyond my abilities at this stage, but it is really interesting to find out how these projects are approached.
Bob, looking forward to seeing the bigger one and mounted on a stand. Sounds like a great idea.

Regards for the New Year,

Wow, can’t imagine how you have created your Spiral Shells.

You’ve put your local critics on their backside, well done – relish their awe and wonder!

Spirals by Steve ( has a step by step video on how to do these. I’d have attempted one by now, except I don’t yet have a scroll saw. I’m looking at building Izzy Swan’s Drill Powered Scroll Saw some time soon and then it’s spirals for the family for Christmas!
