Partfile for wooden chair seats

[cartar]

Are there any special considerations in making chair seats with relief for buttocks.

[mitch_prest]

size of the buttocks

[billp]

And muscle tone as well....
There was some talk a few years back about people using "memory foam"to do a "butt fitting" from a customer, and then they would use the Shopbot probe, or a laser scanner to get the exact size(s)needed to make a truly "custom" fitting chair.
Then a few of us lobbied for the "Butt wizard" but NO software company had the vision to follow up on this project.....
As far as the probing process, it MAY have been done successfully, but to date no one has admitted trying it...

Have your client sit in some wet plaster of paris and let it dry. Then peel them out and probe the plaster.

It should make for a perfect fit!

That is if you can get them out of it.

Whatever you do, DON'T suggest a probe of the butt.

... joking of course.

I once did a seat with a 3d file that a buddy sent me, took forever. On my second try, I just did a profile cut of a series of several successive contours (outlines) starting as 2 small circles and ending as the double kidney / butt shape with a wide core box bit. Even after a little sanding, this was much faster.

In aspire you could easily create the base shape for the seat and the sculpt the butt ... recess to fit with the sculpting tools. Smooth and viola. Save as component and your good ta go.

Alternately and more pain intensively you could make a 3D object with the butt dish in it and export to DXF or some other format that works in your software.

HTH,

... butt dish <snicker> ...

Has anyone ever rowed a racing scull? They are the long skinny boats with the long oars low to the water and the seat slides. Mine have sculpted butt seats out of mahogany.

A guy back in Seattle was making "custom fit" seats for kayaks and such using the plaster of paris method (with plastic liner) and then using that for a form to mold and then casting them in epoxy. Considering the gentleness of the slope, etc, you could do a pretty good job roughing it out quickly and then sanding down the ridges.

I particularly like the "Kilt Seat" in the following thread on the Vectric forum...

I hate to admit it because one could discern that i may have had ulterior motives in mind but I once had a girl come over and i took my laser scanner and made a scan of her butt in order to make a chair for her.

Needless to say it fit her perfectly, I on the other hand was quite uncomfortable.

Jack, Ironically, if you were to advertise such a service, especially in major metropolitan areas, I bet you would be very, very busy.

Jack...How much for the laser scanner?
I think there would be a market for people buying chairs with Anglina Jolee's butt print.
;-)

[phil_o]

Chuck, have you searched Ebay or Craigslist. I wouldn't be surprised if that item was available.
Are we off topic yet?

[navigator7]

Off topic? Phil are referring to the laser scanner or Angelina?
What....am I going to be the butt of this off-road topic?
Why did they name it threads? It should be called rails.

Besides...the best relief for buttocks is hard work.

[phil_o]

Sorry for the confusion, when I saw your smiley I assumed my reference to Angelina's butt being off topic would be obvious.
The laser scanner would be a great way to go.

The kilt chair is hilarious, the question is how to do a quick 3D model like that for custom seat design. I have thought about doing a similar thing using a bean bag, followed with a plaster cast of the imprint, then the contours would be closer to correct in the weight bearing shape.

Currently, in Maryland, there are such imprints all over the place,,, in snow.
I do'nt want to steal the thread,,, but while reading this thread,,, and looking out my window,, I can see imprints of just about any body part one might want -- depending on how someone fell in the snow.
Just struck me funny,,, so now I'll hush up.

A few years back there was a company building custom fit race car seats. They used a general seat mold, put it in a large plastic bag, and then you sat in it and they filled the bag with expanding foam (like you use to insulate cracks in a building). Worked very good for a molded seat. Might be a good way to make a pattern for scanning.
