Baltic Birch Chair?

[cabindoors]

Has anyone seen this chair made on a ShopBot? I downloaded the pix from this forum along time ago and now can't find where I saw it. A search didn't seem to help. I also have the .dxf cutout files.

That is pretty cool.
Tom would you mind sharing the dxf files?

Tom,
That is nice, can I get a copy of the dxf. My wife has been looking for new chairs.
Thanks,
Gerald

I'll send the .dxf file that I have if you email me (I'll reply and include as an attachment).

After looking at the file, it is a result of a traced raster file. I've made an attempt to overlay each section so that they'll match perfectly (but some more work is needed). I'll include the original raster file and chair picture.

Unfortunately, there were no assembly instructions. It shouldn't be too hard to figure it out though, and if anyone does I'd like to make a set of dining room chairs too.

I think that they could be made of Baltic Birch Plywood and compliment a "high priced" table that I'll make.

Please include the word "chair" in the subject line of your emails.

Thanks

wow, hani al mandeels stuff looks great!!!!!!!!

[Brady Watson]

Yes - Hani's work does look great. I'm not 100% sure, but I believe that this is one of Hani's original designs. The right thing to do would be to contact Hani and ask him, and if it is, get permission to use his design rather than helping yourself to his by bitmap tracing what he was generous enough to share with the group. He gave the group the plywood & assembly concept. It isn't hard with a few stitches of creativity to come up with your own design, loosely using his as an inspiration. I know personally, I would be ticked if people were stealing my concepts and designs and freely dispensing a hack digitized version to a large group.

You can contact Hani at his current email address: hmandeel at gmail dot com

Brady,
Thanks for the info. I like the design but see some changes I already want to make, solid back to carve into, provisions for a seat cusion, adding arms, and changing the leg and feet design. I like the concept of the layered plywood, wish I would have seen it sooner. Quicker than my mortise tenon work, and the design can be modified quickly, and built quickly.

Brady Watson,

I'm sorry that you feel that I "stole" Hani's concept that was freely posted by him and am "dispensing a hacked digitized version".

All I intended was to find his forum link and revisit the idea. Jay gratiously found the link and posted it again (above). I think that it is a design idea that is worth following however.

I'm real sorry if I've offended anyone and in particularly Hani.

[Brady Watson]

Tom,
My post was not intended to make any accusations or flame anyone, so I'm sorry that you took it that way. It was just a reminder to be courteous about duplicating someone else's design without asking permission. Regardless of whether or not it is to be used commercially, it's still good practice to check before any assumptions are made about it being copyright or intellectual property. Often times, if you think that there is even a shadow of a doubt that a design may be intellectual property, it probably is.

I think it's great to take a concept and make it yours by adopting joinery techniques and light design cues, with your design being the dominant theme. Stacking 2D to make 3D is certainly nothing new.

Anyone posting pictures of there work or others work are a target for others to copy, this is even true here on this forum in the Show and Tell and camp shopbots, when someone show off there work to others that have the same machine and tools, who is to say that there hard work is not in others homes or on the market.
When someone posts a picture of there work there is no guarantee that it will not be duplicated in some way.
Over the years I have had my work done by others without my permission but I blame no one for doing it or selling it.
If I did not want my ideas to be copied by anyone I would never post them on forums where they have the machine and ability to do so.

Just my 2 cents

the question I ahve is the material 1/2" or 3/4"

[jseiler]

I'd bet its 18mm or 3/4". Counting the slats across the back gives 8, plus doubled stats on the ends would give about the right width for a chair.

[dubliner]

"I made this chair out of 1/2" plywood layers all the way" HM

[jseiler]

hmmm...always opportunity to bet wrong...

[gwilson]

If I assembled it right it using 3/4" material, if figure 21 3/4" wide.

Hani's chair is nice and clean and I like the post assembly shaping and finishing that he did, but as Brady said, there is nothing unique about this construction process.
I have worked with many students over the last 12 years who have constructed many different types of furniture pieces using this technique. On an average, we have had about 5 pieces a year that were designed and built like this. They haven't always been the most elegant pieces, and they tend to be heavy because of the mass of material. This technique, however, is a good way to prototype designs that might otherwise be injection molded or created through some other more involved manufacturing process.
Before the ShopBot, we had people rough cut the parts with a bandsaw and clean them up with a hand held router using a template and template guide. So the ShopBot makes the process a lot easier and it clearly makes for more precise hole placement.
We have used everything from 1/4" plywood to mdf, particle board, and so on. We have also used various pipes and threaded rod to tie them together.
We have also had people tearing their hair out because they have used too many through dowels, or their hole sizes were too tight, or the actual dowel size didn't match the nominal dowel size. It can be a real pain to fight all of these pieces into a stack sometimes when you have glue drying and once you apply the glue to the holes and/or the dowels, everything swells a bit.
I like Hani's screens a lot and have shown the pictures that he posted to a quite a few people. Are you still out there Hani?
