Chopper Leg CNC designs - these are pre-prototype. While not complete,
there's enough there to see the structure. Chopper Foot drive is now in
it's 4th prototype. I've decided that blind pockets are not going to be
more difficult for builders to deal with than it's worth and I'm taking
them out of the design. As always, I'm looking for comments, questions
& suggestions from builders.
09/17/18 - Chopper Foot Shell & Apron, Battery Box
& Foot Drive Designs Posted - As the time line notes, I've
been working on integrating Chopper's foot design since early this
year. It's really 4 separate, interdependent, designs: foot shell
& apron, battery box, and foot drive. Given that
dependence, I'm going to be packaging the parts together when the parts
are available for sale. Right now I've got second prototype parts in
for cutting by the CNC shop. In the meantime you can preview the design
and see some of the details on the Foot Shell & Apron,
Battery Box, and Foot Drive page (it combines what were
previously separate pages).
07/29/18 - Chopper Head Finalized, drawing files posted,
CNC cut parts are available for purchase. Added a parts pricing page .
- Updated Head design with the
release of Version 1 of the head! Looking for comments from the Chopper
03/27/18 - Added web page for Chopper's
Foot Drive. (obsolete)
03/13/18 - Made
design changes to the Foot to accommodate using 4in wheels.
Made additional design changes to the Battery
Box to make it easier to build them.
01/07/18 - Added foot and modified battery box designs with 3D .pdf
& .stp files.
Happy New Year!
- Added 3D .pdf and .stp
(step) files for Left & Right Leg and Skirt (including
prototype construction for the Skirt)
Added body 'features' to the Body listing. Added composite head
illustrations to Head listing. Added a partial
list of References.
07/23/17 - "rolled Flat" version of Head skins
posted see here
Shell & Apron, Foot Drive & Battery Box
this point, I'm posting these designs for comment. I'm
looking for Chopper Builders to point out errors or omissions in the
designs so that I can update the drawings before I proceed to create
building plans. I have also been unable to find much
information on Chopper's Center foot.
2017 - I've been unhappy with the 3D CAD
package I've been using for my
R2 designs. There are two packages that became available more recently.
One that I decided to try out is Autodesk's Fusion360 (F360 for short).
The package is
free [as long as you are a student or your business makes less than
$100,000/year :-) ] is cloud based, and enables the sharing of designs.
learn if the package would work for me I decided to try designing 3D
models of Chopper. There's a steep learning curve, not
helped by the lack of reference manuals, and the sheet metal feature is
in Beta. In spite of that I think it's worked out well. Here are some
of the results. Update on F360 (9/20/17) -
I've stopped designing with F360. The package can export .dwg files but
the files exported can only be read by Autodesk products.Until Autodesk
fixes that bug (it's apparently been that way for a long time so I'm
not holding my breath!) I can't use the product to generate drawings
that I can give to my CNC shop! Meanwhile
has been bought from 3D systems by Alibre design (the original crew of
design/support staff!), is again Alibre Design and now more focused on
supporting and improving their product.
no longer posting links to the F360 files. Per the
above, F360 can't generate Autocad .dwg files that other drawing
programs can read. [ie, you have to have the Autodesk $$ version!]
I'm using Alibre Design to generate .stp (step) format files. Most 3d
design software can read .stp files. If you need a different format let
me know! The download link is located on all of
the pages where a .stp file is available.
First, it was PaulG
(TheHobbyGuy) who suggested that I should
create a CNC styrene version of Chopper. So, in some sense it's all his
Second, A number of Chopper builders have posted
documentation on-line that I have used to create these models. I'd like
to give them credit for their hard work and thank them, without their
documentation this project would not be possible! Primary contributors
included: Cleofett, TinyP, Joymonkey and others.
A partial list of the References I
have used is here.
