The NextGen Frame
Conversion to Tab Core
Some Background
Above:
The original Core 2,3 and 4 parts have been modified to have slots
where they used to have semi-circular notches for the PVC
pipe. A new set of ribs were added to
replace the pipes.
Right: The notches are made progressively smaller from largest (core2) to smallest (core4) to make inserting the Tab Core easier. |

Warning! Gremlins At Work The pictures of the Tab Core panels above all show the front of droid holes lined up at the top of the panels and the guide slots and panel mounting slots all lined up as well. Somewhere along the way something changed. I haven't been able to determine what quite yet, or fix it. In the pictures that follow you can see the Core 4 panel lined up as you would expect. The 'front of droid' marker lines up with the one on the ring! However, when you try to line up the Core 2 and Core 3 panels you will find that you need to rotate the 'front of droid marker' to one side (or the other) in order for the guide slots and panel slots to line up. | |
The balance of the Tab Core assembly is unchanged. Just verify your orientation before applying glue! | |
In the beginning the assembly is a little like making a 'house of cards' - use tape to hold the first rib in place. Make sure the 'front of droid' markers are all lined up. |
I'm using the back edge of my workbench as a 'third hand'. With the first rib past top of center the assembly will want to roll towards the back of the bench. Insert & tape the second rib. |
Above: continue the assembly with the 3rd rib. Right: with 3 ribs in place you can stand the assembly on end to add the 4th rib. Below Left: trial fit the core4 panel. - You can orient the motor location to either left side or right side of the Droid. Below Right: Insert the core panels in the locations you'll want them. There are three, but you don't have to use all three. |
|
Panels shown here are aligned with the left/right side of the droid |
Replace the Core4 panel |
Above & Right: Run a bead of the #16 Weldon to temporarily hold the ribs in place |
|
The rest of the pictures here show the core being inserted into the frame and then several views of the core in place. | |
