Laminated Stacked Bowl

There is a lot of information on this on the segmented woodturners site. Membership is cheap and you need to be a member to have access to all the wonderful detailed information. If your going to use angled wood you need to use only the best quarter sawn wood to try to prevent cracking.

I've done it with both stack laminated and bowl from a board projects. I learned it from a photo I saw a very long time ago where they had taken a bunch of segmented oak rings and tapered each ring. Glued them up so the narrow ends were all together on the central rings. Made a very stricking piece.

Thanks Guys. I do belong to the Segmented Wood Turners as well as the AAW. I'm asking the question because I want to get some interest going in finding new and creative ways to screw things up. Typicaly, when you start one of these, you cut a lot of thin pieces to stand on their sides, glue them together and resaw all that.

My question is what would happen if instead of standing them on their sides and gluing them together, they were glued at some sort of angle, like a Log Cabin quilt pattern?

Just trying to cause trouble but thanks for rising to the bait.

Wouldn't that be an open segmented piece ?l

No, John. In this process, we make a board. Typically it consists of a lot of thin pieces stood on their sides exposing the thin surface. That's glued together. And usually it's about two inches thick. That gets resawn; I like 1/4" thick pieces. Concentric circles are drawn on and cut out of the resawn surfaces, glued back together in a manner similar to traditional BFB processing, but twisted into some sort of pleasing pattern.

No openings or gaps, but there could be. Leave out a piece of wood during initial glue up and you'd have an open segment, sort of. What Have You Just Done? You should be ASHAMED of yourself. You just opened a new can of worms. Leaving out a board in the original glue up would work if you'd planned it well and it was there in regular spacing.

Hate it when someone like you shows up and asks a question that sends me spinning off into the dark voids.

Thanks Buddy. Come to Maine and I'll cook up a lobster dinner you'll never forget.

I'm not sure I'm following you but it sounds interesting. I've done what they call 3rd generation pieces where you glue up pieces, then cut then at different angles and then glue them up again into a board. Then cut this at a different angle. I would have to look up the book I have to tell you more. It's been years since I did that technique.

Hello Jerry: I do some of these. Can I offer any answers to,your questions?

Hi Jerry,

I don't do these yet, but do find them intriguing -- much more so in my case than traditional segmented work.

I'm pretty sure Michael Mode has already done what you are describing -- working with laminated boards that are not parallel or potentially curved.

I don;t want to post a photo of Mike's work without his permission, but you can see his work via either a google image search, or his web site.

Safe spinning,

Joe did a very good presentation on these to our Chesapeake Woodturners club meeting in December and is, I think, responding to an email I sent urging him to pitch in here on this topic. He had a good handout for us, and showed some very nicely done pieces that he did with his methods. Great stuff and he makes it sound pretty easy and quick to get a nice result.

Cheers -- Chuck

Yes.. I've seen this as well. Hardest part seems to be keeping things from slipping around as you stack the tapered cuts together. It would add an interesting dimension. I was thinking about cross cutting my "cutting board" like stack on the diagonal a couple of times, than gluing those up before cutting my bowl from boards. I like this idea.. I've not tried it but it could produce a remarkable bowl.... Humm... I might have to try this.. Again.. my only concern with either approach is keep the boards from sliding over one another....

Re: Laminated Stacked Bowl

Hot glue stops or alignment pins on the rings before gluing them up. I fought the same issue and ended up turning a few to redulously thin dimensions to save them because the rings slipped. When alignment is critical on a project I now either hot glue or CA glue small alignment stops either inside or outside (whereever necessary) so that it can't slip when wet with glue.

This is not my thing, so ignore me if this is a stupid suggestion. Has anyone tried a few grains of salt in the joint to grip the opposite surfaces and prevent sliding?

Re: Laminated Stacked Bowl

john lucas

I've use sand grains, not salt. It works sometimes but I always tried to use it on the pointy end of segmented rings and this area would be turned away. On bowl from board projects very little of the ring is turned away and I was always afraid that a piece of that sand would be right at the final turn line and show up so I never tried it there. You still have to line it up and when you have glue squeeze out it's hard to see the exact joints. If you glue on alignment blocks it takes care of the problem because you glue those on without any squeezout so it's easier to align things.

If I understand your request correctly it sounds like you are following along the lines of the work Max Krimmel did with his patchwork bowls back in the 1980's http://www.maxkrimmel.com/
