Here is the box opening of the Lazy Susan Bearing. You can order direct from Rockler, or get one off of the Astromech.net club forum. The one off of the forum is a Rockler with the holes pre-drilled in the factory to meet club design to attach to the base of any frame.
Blue Painters Tape To Hold On Dome Panels
The method to hold on the dome panels is often a topic of debate. JB Weld, Silicone, Tape and whatever else you could think of. After looking at all the options, the easiest for me seemed to be using painters tape rolled over, but with glue stick on the non stick side so it stayed in a compressed loop.
Rip the tape in a strip twice as long as the panel.
Attach half to the panel and put glue on the non sticky side.
Fold that over and create a loop with the tape and press it down. Cover the entire panel with the tape.
Center the panel and press it firmly into place, making sure it is secure.
Repeat this step for all the panels until they are completely attached. The glue will dry and hold the loop together.
Installing Captive Push In Studs for the R2D2 Dome
The majority of builders use Captive Push In Studs to help hold electronics in place on the dome. Although they are supposed to be mechanically pushed into the aluminum, most do not have this capability.
The tools used are a sharpie, drill and small bit according to the captive stud specs, and a countersink bit.
First, the spots must be marked for the studs and than a small hole drilled. I did mine from the inside of the dome.
After the small hole is drilled, the 120° 3/8 drill bit is used to countersink the dome from the outside.
Next, the captive stud is pressed in. It sits just above the metal and should not be flush. The goal is to tighten the stud until the barbs on the backside grip and twist into the dome.
Once, in place, use a washer and nut on the backside to torque the stud into place. You will know when the stud is seated properly when it does not move. It would have to be hit with a hammer to get it out. I installed the PSI’s and Holoprojectors with my DIY mounts.
Here are the captive studs intalled from the from to hold the Logics and PSIs in place.
This is what it looks like from the inside.
