R2-D2 FRAME CONSTRUCTION
JAG V4 Frame Kit Completed
02/26/07 : Mounting method for the LDP to the UAC assembly. I drilled
Wayne Orr's LDP and tapped for a 6-32 screw. Holes were then drilled
into the side of the UAC assembly.
02/26/07 : LDP mounted. Removable as I plan on installing a laptop/
mini DVD/CD player behind it... Put together with 2 6-32 FH machine
screws.

01/26/07 : Installed utility arm pivot bushings. The idea is the pivot pins will spin in the bearing
and the utiitlity arms will be secured to the pins. That way, servos could be used at the end of
the pins to move the rods. Don't know if I'm going to do that yet though...
01/26/07 : tapping utility arm for a 4-40 set screw to lock on the utility arm shaft.

06/14/06 : Frame arrived at my work place. Box was wet
probably from the tropical storm we had while it was
in-route. No matter, aluminum does not rust!
Assembly of the JAG V4 frame. Only took
about 1.5 hours to put it together. I had to run out and
get the screws for the motor hub (6 x 25mm). Had the
satellite motors turning too. All left is to tap the holes
for the Guy's dome drive.
Sat' motor, mounting plate and hub.
Used a small mount of grease to hold the shoulder bolt
bushings in place. Dont' forget to put the "JAG stops"
in the correct orientation, slot should go forward.
Finished frame with Sat' motors installed.

06/15/06 : Tapping holes in top
ring for Guy Averett's
dome drive assembly. 1/4-20 UNC tap with lube is
all that is needed.
Watch that no filings get in the sat' motors!
Drilling out one of the four holes for mounting the
Rockler dome bearing to the frame. These are
#10 holes. I felt that 1/4" were too much here even
though the frame ring holes are drilled for that...
Not shown: the holes were countersunk for FH
screws.
NOTE: Make sure the bearing is sealed with tape
or you will get the metal shavings in the bearing :(
Frame with AP Dome Drive, front vents and
Rockler dome bearing installed.
I put the dome on just for kicks :)

06/17/06 - Start finishing the aluminum utility arms.
These arms did not come drilled, so I carefully marked
and leveled the arms to drill the holes. The arms came
with machined 10-32 pins. I had to be careful because
I do not have the proper tools/mill to do the job. Came
out pretty good considering.
Drilling the 0.25" arm pivot holes.
Now the tricky part. The arm HAS to be level to
use a hand drill with a bubble level on it. Then I
very carefully used a hand drill and kept the drill
level so as to drill the hole in the proper plane.
Hold that drill level or you are going to
mess up a expensive part!
Sure was nervous HAND drilling the
pin holes, but they came out fine :)
This picture really throws it off. The tap
was just started and not really in-line with
the hole... the pix is a little off too :)
Utility arm pin installed. Whew... got it in the right
plane AND centered. Not bad for hand drill and
backyard machining!
