As alway, start with a
detailed CAD of what we intend to do. Using CAD
programs is fun! |
 |
The frame pieces are
too large for me to make myself so I got the cut for me on a
waterjet machine. Once I got them they had to be
modified. Here I am cutting a recess for one of the
bearings in the drive train. |
 |
Here is the bearing
pressed in to the inner rail. Petunia has 16 such
bearings. |
 |
My little mill working
hard to cut another bearing recess. Luckily my friend
Pete of Team Cosmos let me use his mill for a lot of other
stuff, as mine is just too small to do much of the work. |
 |
Here is the front mount
for one of the drive motors. |
 |
After much drilling,
tapping, and countersinking (about 150 holes), the frame is
taking shape. |
 |
The completed frame,
along with the axle for the weapon. It's starting to
come together now! |
 |
The chunk of pipe I got
for the weapon is exactly twice as long as it should be, so
I have to cut it in half. |
 |
A sawzall does the job
without too much fuss, even though the walls of this tubing
are 1" thick. |
 |
Done. |
 |
As usual, building
pieces of the drivetrain is the next order of business.
8 shafts, six spacers, and miscellaneous other parts. |
