This is a build tutorial for the Luke ESB hero lightsaber as it is currently considered most screen accurate.
It probably will take around 2 to 3 hrs to complete, assuming you have all parts and tools available.
OK, let’s start!
- Luke ESB set (T-tracks, Kobold clip, D-ring, edge connector, screws, metal tape, rivets)
- Vintage 3-cell vintage Graflex flash handle
- Additional red Graflex button
- Rotary tool (a Dremel for example) & bits
- Miter saw (I use a small table circular saw)
- Transparent scotch tape
- Permanent pen & marker (able to mark the black T-tracks)
- Cross head screw driver
- Epoxy glue & wooden spatula
- Drill & bits (2.5 and 4.0mm)
- Rivet gun
- Box cutter
- Narrow file
- Sandpaper (fine)
Remove the protective layer and attach the tape to cover the Graflex logo of the clamp.
In order for the edge connector to sit fixed in the clamp, a piece of transparent tape will add some thickness so it will stay put. Put the edge connector in the clamp with the thick copper stripes closest to the clamp lever.
Make a marking on each of the six T-tracks with a marker. In this case I used a white paint marker. The length is 92mm (3 5/8″). Cut the T-track a little bit smaller (90mm) if you want to allow movement of the handle part in the Graflex clamp (see #6).
Cut the T-tracks using a miter saw (I use a small table circular saw).
Use a rotary tool with small cylindrical ceramic bit to mill away the plastic in between the cuts. Do this carefully and try not to cut away material from the flat base of the profile. You might consider using paper (masking) tape to protect the flat base.
Use a file and sandpaper to create a smooth surface finish of the plastic T-tracks.
Take the 2-component epoxy glue and a wooden spatula. Put some on a cardboard and mix well. Use transparent glue with a curing time of around 5 minutes.
Put the Graflex handle inside the clamp.
Now this is important: if you want to be able to detach the handle part later, push the handle in the deepest position. Check the length of the T-tracks. For this deepest handle position, 92mm track might be slightly too long. Cut the T-tracks to 90 – 91 mm in this case. If you pull the Graflex handle to its longest position, the length of 92mm is correct, but you will not be able to detach the handle afterwards.
Now glue the second profile opposite the first one. Then place the third one on a 60 degree angle in between the other two (I did this by guessing by eye-sight). Place the fourth one in the middle of the gap next to the third one. Glue the last two opposite the third and fourth and you’re done.
Leave the handle bottom up as in the picture for the epoxy to harden. (Check the leftover on the cardboard to check when it’s done!)
While the epoxy is curing, use the rotary tool with a circular grinding bit to cut away the beer tab fixation. This is easier than it looks. Watch it that you don’t scratch the rest of the Graflex. Remove the tab and take away as much of the fixation as possible. Put back the red button and replace the glass eye with the other red button in case you hadn’t done that already.
(It’s also possible to remove the connection of the tab from the inside by removing the innards. RPF-member dr_slurpee pointed this out to me)
Place the Kobold Clip on the bottom of the handle orienting it in line with clamp as shown here. Mark the two holes with a permanent pen.
Use a rivet gun to attach the Kobold Clip with two flat head 4mm pop rivets. The Kobold is now tightly fixed to the handle! Almost done now!
Use a 2.5mm (0.1″) drill bit and drill a hole in the center of each groove through both the plastic and the metal of the Graflex handle. Because of the T-track plastic, this can be easily done by hand.
Screw in the six metal cross recessed pan head tapping screws.
10. Put it all together
Assemble the Graflex top inside the clamp (watch it that you put it in the correct position!).
Clean up all the mess you made and you’re all done!
