Parts breakdown and construction theories

Back in the early 2000’s little was known about the items used to construct this prop, in fact only the graflex clamp and a strong feeling about an as yet unfound early Armitage Shanks Starlite sink tap were all that could be nailed down. Through the years this community scoured websites, junk shops, antique malls and under sofas for any and every clue to identify the constituent parts that made up old Ben’s lightsabre.
The first major domino to fall, even before the grenade I believe, was the Texas Instruments Exactra 20.
This humble pocket calculator housed the activation plate for the ANH lightsaber props. All three lightsabers from that seminal first film used this LED magnifier as a tie that bound them together in design.

A good read about a later but significant discovery of the bubble strip.
Hello there, A couple of weeks ago I received my first Exactra 20. Still needing another one for my lightsaber projects I scored my second Exactra 20* and received it yesterday. When I opened it to check the 7 bubbles lens I was totally flabbergasted. I announced my first discovery about the...

Staying in the middle of the saber for a moment or two, we have a combination of the eldest known part, in the Graflex clamp, to the newest discovery of the buttons on the side of it. While known to be some kind of transistor for many years, the model and manufacture remained a mystery until a member new to the community at the time, dropped a bombshell thread that positively identified the buttons. The wonderful transistor thread by
v312 is a wealth of good info.

I was checking some older threads for information, but I got the impression the transistors have not been positively identified yet. So I'm sharing what I've found recently - although these are not really transistors, but some sort of ICs I guess. As far as I can tell it is the correct package...

From the calculator, Graflex clamp, and transistors, we next move on to the No.3 mk. 1 British rifle grenade.
As can be seen in the diagram at the top of this post, we have the familiar shape of the forward grip and neck sections of the saber. Initially, and for a few years, it was the consensus of many here that the forward grip section was some kind of motorcycle grip.
Interesting read here.
My intention here is to start this thread to collect information about the best way to weather the new grenades Russ & Company are doing as well that one you have stored there. I posted this which is a nice collection of photos from varios sources...

Moving right along, we have two discoveries in close succession.
The business end of the saber or emitter as it is rightly called, was found to be a balance pipe interconnect from a Rolls Royce Derwent jet engine.
The very same source of other iconic props such as IG88’s head and contemporary to this prop, the set dressing in the Mos Eisley cantina behind the bar. This elusive part was thought to be a sink drain for a while, then part of a fire suppression sprinkler head before ultimately being identified.
Discovered by
Blaxmyth and can be read about here.
Check out the nozzle-thingy on the bottom right of the cutaway Derwent engine, just below IG-88Â’s head. Possibly an Obi ANH emitter? ItÂ’s here on these pages: http://www.gasturbineowners.com/derwent.htm http://www.gasturbineowners.com/images/a23.jpg...

Next to be discovered was the rear grip of the saber, which was a booster from an ANM2 Browning machine gun.
In keeping with my theme of providing a bit of community history with these items, I can relate that this part was thought to be a heat sink, or fluting iron, and even a lawnmower gear, hence the title of the discovery thread.
The recoil booster, just behind the flash hider was found by
Killdozer and can be read about here.
So here's Killdozer's post: Originally posted by Killdozer@Oct 17 2005, 07:44 PM I did some research on the dart today and I'm now pretty sure that the back half of the propeller spinner was used both on the Death Star Gun (in front of the impeller) and as a little table in the back of Ben's...

Continuing on to the rear of the booster, we find a four piece Armitage Shanks Starlite tap handwheel.
As I said further up this post, it was known early on what this part was, however it was much later that one was actually found by a member of the community. You see, there was a modern equivalent handwheel which was far simpler in construction, and slightly bulkier in appearance.

It was this modern variant of the handwheel that was my very first purchase from another member of the RPF, and thusly my instigation to stop lurking and become a contributing member.
Thanks again ry27 of randomsabers fame.
My first completed replica of Obi Wan’s saber here.
More to come soon…
A teaser of a photo essay for my understanding of how the original was constructed.
