Just a fun project which I had to do to see if this system really works. Cut on the band saw in a continuous spiral
movement at a 5 degree angle. Found that plywood is a bit springy and will try it again with a 10 degree cut to get a firmer grip when pressed open. This is first attempt, maybe a pattern or inlay would take the plain look of the finish but it is another piece of my plywood pile used up. Cheers.

This one is really hard with plywood. You are now officially the master of plywood.
Q: How did you drew the swirl line. Very long time ago, someone told me how to do it by compasses. but because I did not use it, I forgot it.

Thanks for the compliment Sam but I sure have a long way to go. I search Google for “drawing a flat spiral” and found a couple to save and play with. I have tried the nail in the centre of the blank with string wrapped around it, the pencil in the loop on the end and as you and draw the string unwinds forming a spiral. Found that would be better for larger work. Easiest way is to find a suitable spiral illustration, copy, run of some copies and transfer it to the wood with carbon paper. Is the one with the compass drawing two sets of semi circles and join them up? Hope this helps and doesn’t confuse. Thanks Robert for the comment, hey you do great rings mate.

Neat one, Bob. I have seen baskets done like that and wondered how they get a spiral pattern to follow. Did you then have to back the blade out all the way? It seems you would, but do you turn off the was to do that?..............Jim

Really cool Bob, just goes to show that there is nothing that cannot be done. All that is required is a bit of IMAGINATION. great Job.

-- 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.

Bob, I just had a look at your plywood bowl and I thought that looks pretty good…..Then I took another look and realized it was collapsible….That Is Amazing!!!!! It never entered my mind that a bowl could be collapsible.

Well Done Bob.
