I like that very much. Swop it with your avi pic. Much nicer. :wink: =D>

That's an absolute cracker Chas. I'm relatively new to turning. Have you a more in depth wip somewhere that shows the steps you go through to do those segmented pieces?

That is lovely. Well done.

Make a decision on your desired diameter target and work out your segment size to suit.
I use my version of Segment Calculator to do this.
The next operation is to prepare your basic stock and if you use my cutting method of using a Chop Saw, make sure stock is square on all faces.
The narrow pieces can be cut from a thin strip but I more often just slice them on the chop saw.
Check the segment length, and note that you just flip the stock 180 to cut a new segment.
As long as the Chop Saw is set up square and angles are correct then there is no need for sanding of segments, indeed I find the resultant joint lines are better given off saw finish rather than a fine sanded finish.
Clamp the segments firmly, I use jubilee clips, if the angles are correct then there is no need for messing about assembling 180 deg sections and sanding them to fit.
The top and bottom,
The bottom is roughly prepared to form a socket for future turning of assembled parts and then reversed to prepare the mating surface to match the cleaned up segment ring, likewise the top mating surface prepared.
It is essential that all mating surfaces are flat across the faces, use a steel rule and check for 'squeaky' sound when slowing lathe down, once heard it becomes an easy and quick way to prove flatness.
Glue and Clamp the three parts, you only need to rough turn the outers, just size within reasonable dimensions so that it is easier to align the pieces.
Then all that remains is to mount the rough assemblies on the chuck and clean up the outer, part out the central top waste and form the lid opening and clean up the inside.
Meanwhile a few spare lid blanks get their turn in the jubilee clips.

Yes...many thanks Chas....that's REALLY useful. I will try one when I get a free weekend.

I quite fancy giving this stuff a go myself. Need to get my chop saw replaced first though. I don't fancy cutting all the segments by hand.

Another nice piece, Chas, and a very interesting "how to". Thanks for posting.

Great wip many thanks for sharing
What glue do you use on your segmented stuff?

I think the integral knob gives it a little more ... something, but I cant think what? I just know I like it

Not quite, yes they are cut out on the bandsaw (see Link to old WIP above) but there then follows a bit of critical sanding of the profile to match the curves and control the segment width.Melinda_dd":3jccfg6e said:
The inner curve is basically a simple drum sander, the outer is done with a disc sander and a jig, very simple procedure once settings are sorted.
Curve radius is non critical, matching the two is.
I suppose I must get round to divulging how simple the jigs are next time I cut a set up.
Glue is Cascamite, no joint creep, but consequently wood must be ultra dry, folks have a habit of placing things where the sun can shine on them or on a shelf over a radiator.

Does cut down on the turning tasks as long as I don't forget which method I need to mount the blank for turning, a little critical on solid lids due to grain strength on stem area and of course it is dependant upon me being more careful with segment sizing in the first place for the segmented ones.
