(= Request for Build plans - - - - - - The 12' plywood HEX dome has a new home at The DoSeum | San Antonio's Museum for Kids

[Kourosh Momeni]

Hi Robert, hope this email finds you well. I wanted to ask if i may have a copy of the 20ft tortuga dxf files too please.

i will be aiming to find a a place local to me to cut it. i feel this may be better then using pcv pipe.visually looks appealing because of its beehive shape and feel the sun in high temp would not phase it.

I would like to do a 5/8 dome.&vam trying to build it on a 20x20 ft space that is the top part (flat roof), of a garage( stand alone square shaped ) structure, and want to plan to grow different plants and vegetables out of it.

ive been in the group for some time, and asked a few questions here and there, with other builds. but this one looks like it also may be climbable. do you have any thoughts on that?

their were a few at burningman made out of pcv pipes and they were sturdy to climb.

and i was thinking of different ideas to help support the bottom of the frame from moving, but do you feel/think wing would knock it down, or the material together would hold just from its weight?

please share your thoughts when you have the chance.

kind regards,

-kourosh

Hi Robert! 

Just read this! Do you have any other dome in 20ft diameter?

It doesn’t need to be the Tortuga Dome and this is strictly for exhibition!

Hi Kourosh, thank you for your interest in my dome designs.  Up until now, my domes have been built for exhibition purposes only.  They have not been really designed to be structural.  I have had requests to design larger domes.  The largest dome so far was the Tortuga Dome at 16 feet in diameter.  Again, this was strictly for an indoor exhibition.  I have recently been working on a modified Tortuga Dome that utilizes both plywood and 2x4 parts.  The idea is that the components would be self-jigging and assembled quickly using a nail gun.  There would be a wider surface area on the struts for fastening plastic sheeting for a greenhouse.  If used as a greenhouse or outdoors, all parts would need to be painted with some type of wood preservative.  The six inch long pieces of 2x4 could be cut from pressure treated lumber, I suppose.  The attached images are of an unfinished conceptual design for a 20 foot diameter dome.  It would be structural and able to support snow loads and high wind.

I could post a more finished design in a couple of weeks from now.

Robert

I totally understand! We still have time, we need to start cutting by Wednesday though! Do you know how much material we will need? 

Perfect, thanks for the information about the bolts, I was a little worried about that. Thank you so much Robert!

Yes, Wilda.  I was reworking a design for you over the last couple of nights.  I was hoping to post it today, but as often happens, unexpected family responsibilities took precedent.  I will try to post the part files tomorrow.  Attached below, are preliminary views of what I've been working on.  It will require #3/8" bolts that are 4 inches long at the center of each of the 150 hubs.  There are two hub types with their smaller matching bolt cap.  There are two strut types, long and short.  I have tried to simplify the the design for cnc cutting and also for assembly.  Let me know as soon as possible if this looks like it will work for you.

Thanks again Robert!

Wilda, first estimate is about 8 sheets of 3/4" thick plywood in 4'x8' sheets.  I should know exactly tomorrow.

Hi, hope everyone is well during this time.

I was wondering if there is/was an update for the Altos de Chavón dome design? I have some time and found a place local to cut the wood with a CNC Vcarve.

wanted to try it out, only question is will it sit flat on ground surface or have little leg?

Please share your thoughts when you have the chance.
