Jim, you must be doing something right with the glue and timber orientation / selection for the piece to stay together all this time!

Nice

Did you pop in the lathe? And was there any run out after all this time?
Looks good!

Jim, I see it does not show any of those nasty cracks from timber movement. Would love to see this one up close if I hasn't been cared for all that well.

Yes Chuck, it went back into the lathe. There was about 1.5mm run out in thickness and 2mm in diameter. I turned it slowly for sanding only so it didn't make any difference.

Powderpost,

I love the design, and as stated above, you have excellent technique.

By linear laminated, I am assuming the parts are assembled and glued side by side, and the rim is glued on top and then turned.

Wonderful piece!!

Jim, that's surprisingly good % wise on the dia, the warping (thickness) I can understand. I would have expected a bit more on the dia. Just shows how stable these can be.

1993 - now that was when we could still get locally saw milled timber. You should post this one on the other site.

Thanks Paul, linear lamination is a term used by Mobyturns. I first made up a "plank" by gluing strips of varying width side by side. Then it is cut across at an angle and re-glued. This is done several times to get the pattern I was after. The rim was made using a standard segmented ring.

I haven't been able to find a source to attribute the use of the term "linear lamination" in wood turning to. I have seen use of the words “linear laminate” on “Out of Control Woodturnings” segmented website as an initial step to creating multi generation segments. Straight segmenting seems to have been in use as a common way to describe simple laminations.

I started using the term to broadly describe simple or even more complex lamination techniques in which the grain orientation of all laminations in the glue up are essentially aligned in one direction i.e. parallel - as opposed to segmenting where each piece is usually placed radially with the "long grain" orientation indexing around the bowl.

There are many exceptions and variations of course – i.e. Max Krimmel's work, and the evolution into multi generation laminations! Jims platter is a wonderful example of a linear lamination one generation on, and his 2nd & 3rd etc generation platters are a joy to behold.

The “bowl from a board” technique is a great example of a common linear lamination technique that has evolved from simple stacking of rings to radially offsetting the cut rings in each layer. Tunbridge turning, at least some of it and coopering or staving are other examples.
