A possible future sticky depending on response.

In addition to helping resolve doubts about whether hypothetical specs will result in an actual chair that meets its intended objectives, I have found that one can learn a lot about the various products and their individual nuances by comparing CAD drawings.

Over the past year, a number of members have posted their CAD drawings on this forum. It struck me that a single thread devoted to CAD drawings could become an invaluable resource for somebody looking to spec out their own chair.

Might I suggest the following "protocol" for members who are gracious enough to post their CAD drawings for others ...

1) Make sure any personal information has been removed from the drawing.

2) Use the "Go Advanced" feature to add a title using the following format to make searching easier...

ww x dd Frame Angle Manufacturer Model (Unique Feature)

Examples...

15x16+1 85 Degree TiLite ZR2
15x15 80 Degree TopEnd Crossfire Titanium with Ergo Seat

3) If the actual chair has been delivered, post the CAD, a brief description, pics, and specs.

4) To keep the thread focused, post a separate thread for discussion and link to that thread. This should limit off topic excursions. Additionally, those who are posting their CAD in order to get advice will have their own thread devoted to their future chair without derailing the purpose of this thread.

It is my hope that this thread with the suggested protocol could create a truly unique repository of specific product information for reference while at the same time providing a way to address the needs of those who need help by linking to individual threads.

I know my "protocol" sounds like a lot of hassle for some, but spec'ing out a custom ultralight is serious business. I have a feeling that those of us who go through the trouble of actually getting a CAD drawing won't mind the additional work.

Let's see where this takes us. I'll post an example shortly.

Did you get a full CAD drawing with your specs? I can't recall if you posted a CAD or just a sketch. For all I know, you might have given them the drawing.

It sounds like Oracing uses slightly different specifications when they build their frames. It would be an excellent addition to the CC CAD Repository.

.

Here you`ve got it, is a Xtreme Box with 24" rear wheels and 4" casters and aluminium side guards without fender.
The measurements are in millimeters, 1"= 25.4 millimeters.
I will post pics once this monster is made.

Just thought i might be able to add something to this topic as it says CAD im an engineer and read another post on the forum asking how to open cad files if the were not sent in pdf or jpeg format
theres a free download from a company which is basically a cad program it lets you open dxf or dwg files which is the format most companies send their drawings out in its called draftsight and its a free version of autocad more or less

New ZRA S2 w/ ADI Disc brakes, Pushblax, and more

The chair is a 15 x 17+1 ZRA S2

Here are some of the basic specs:
89° front angle
17" rear seat height
20" front seat height
17.5" seat to footrest
17"+1" seat length
11" wide titanium w/ABS cover footrest with V front end
3.75" inch center of gravity
1.5" rear wheel spacing*
6° of camber – aluminum camber tube**
4 x 1.5" Plastic Wheel w/ Poly Tire (Froglegs)
Tilite standard fork
24" Spinergy LXs (with black hub – ordered from Matt from Pushblax)
Pushblax Double-Stuffs on short tabs
ROHO Hybrid Elite
Bodypoint Hipgrip***
ADI Disc Brakes w/ Variable Lever
ROHO Jetstream Pro (made by ADI) with adjustable hardware

*I started off with 1 inch spacing but the Hipgrip brackets rubbed so I had to send it back to ADI for more rear wheel spacing
**ADI can no longer modify carbon fiber camber tubes for their disc brakes
***I might have to do a longer post on just the Hipgrip itself but in short I started using it several years ago in order to improve my sitting posture due to a small pressure sore on my lower lumbar back that resulted from the combination of my kyphotic (slouched forward) sitting posture at the time and scar tissue over my vertebrae left over from the implantation of a baclofen pump. Gradually I was able to utilize its ability to hold my hips in my cushion while reaching for things that would normally throw me out of my chair, like books on a shelf or something near the floor. Due to the fact that I have an incomplete injury (C-5 ASIA C) I was able to develop greater strength over the years in the few partially innervated muscles in my torso and back, for instance while riding the bus every day or scooting around campus in Seattle, because the Hipgrip was able to secure my hips requiring me to work on stabilizing and balancing my upper torso.

I was able to reposition the anti-tippers by removing set screw on the side and putting it in another hole [see ZRA S2 Suppliment page 6-6 (32)]

I'd like to thank all the folks here at CareCure that have shared their experiences with their own chairs and equipment, and whose posts contain valuable information not readily available elsewhere.
