A segmented eye bowl pattern

[Walney Col]

This pattern is for a simple segnemted eye-shaped bowl featuring the Japanese symbol for "beauty".

The segmentation is of 1/2" or 12mm thick wood in a simple 5 piece glue-up with contrasting stripes which when finished will form a decorative swag along the length of the bowl.

If you don't have sketchup right-click the following image and select "save image as..." to download it to your computer then print it out at 100% to produce a bowl approximately 260mm long, 180mm front to back, and 124mm tall.

I made the glue-up yesterday adding 2 more mohogany strips and it came out rather well.

All ready for drilling and sawing now.

At 7mm wide they're going to be my narrowest rings yet so there's a reasonably high chance of mishap if not in the sawing then in the sanding process during which I'm hoping to end up with a wall thickness under 4mm. I'm aiming for 3 but given how much I shake that might not be very realistic. I'll just have to see how I feel when I get down to 5 :roll:

Hi Col,
+1 for the finished item, Ive always been interested in the technique you're using for bowls. Id like to try it myself one day, (when I have time) I must put it on the list of stuff I want do.

I have lousy health and don't always feel up to cutting but no matter how poorly I feel I always enjoy the planning and design process. I hope to start cutting tomorrow and I'll post more as soon as I can. The bowl's a present for someone who's bedroom is decorated in a japanese style so I'm thinking of ebonised it all over leaving only the change in grain to reveal the swags. It's a bit of a shame imo since I'd prefer it natural colour but she's my big sister so I can't really refuse. haha

That's an excellent point but not perhaps in the way you intended.
美しさ does indeed mean "beauty" but only if you don't accidentally mirror image it as I did!

Good catch Brian!

Nice work col. I will be interested to see the finished bowl because I can not see what makes it go vertical. Perhaps I am being a bit thick this morning..

I've got an idea how, but would also like to see the finished bowl and how Col does it.

I've done a bowl from a board on the lathe and it maybe that the process is similar.

[Walney Col]

This is a cross section through the middle of the bowl. What makes it go vertical is that all the rings are cut out with the scroll saw table at a steep angle (in this case approx 30 degrees) so that the inside dimension of an outer ring is identical to the outside dimension of the next ring in.

The rings can then be stacked on top of each other like so:-

To avoid having to do massive amounts of sanding it pays to work out what angle you need to set your table at so that ring1's outer dimension is as close to ring2's inner dimension as possible. There's no maths involved though, just transfer whatever ring width you want to use to the edge of the board...

...and adjust the angle of the table so that the top and bottom of the marks line up with your blade like so.

Hope that helps demystify it a bit

Thanks col, you have explained it very well. I must find time to have a go at cutting one.

Regarding angles Lidl are selling some digital angle finders this week for £8.50

I don't suppose you've got a link for them, I can't find them on the web site and our nearest liddl has just shut down so I'm hoping I could get one online.

Cheers Brian, but the one I got all excited about getting for a tenner is the little square box magnetic type you can sit on a table saw blade of a scroll say table and watch the reading change as you tilt it.

So much more convenient than having to peer underneath the table at an angle gauge that's probably not accurate anyway. The cheapest I've seen so far has been over £20 which is a bit rich for me at the mo, I have a new lathe to save up for first

 

[Walney Col]

The wife was back and took a bit of video today, the idea being that when I give the present it comes complete with a video record of how it was made. It'll probably be far too long and boring for most people's taste but I want my sister to be under no illusion that it was a simple 10 minute job! I'll post a link to the video here for anyone who's really interested in the details.

 

[powertools]

This is brilliant and way beyond anything I have tried and I guess beyond what most others have done.
A video would be good.

 

[Walney Col]

Thanks powertools. You might or might not want to mute the sound on the video when it arrives. It's going to be very very long indeed and feature Japanese music all the way through to teach big sis a lesson

There again I suppose I could do a cut down version specially for scrollers.

what about "Turning Japanese" by The Vapours for the soundtrack? oooooopps sorry its Scrolled not turned 9-)
Look forward to seeing the video Colin....will there be any bloopers like You've Been Framed?

Both great ideas but the bloopers will probably only appear on the scrollers version, my sister still thinks I'm perfect!
