All original parts Obi ANH saber - adding cotter pins

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

Hi Markus,

I always though that the figure eight hole is made from 2 'O' drill holes which partly overlap in the middle thus the occuring of the figure 8. That way if you now push the cotter pin once through the first hole and then pull it tight towards the booster so that it gets stuck in the second 'O' of the eighthole ... savey? So there's no need to go in and back out!

Sorry Chaim. I guess I'm just too dumb to visualise your whole idea of the use of the cotter pins. :wacko

Well I've installed the real booster cone. Just those cotter pins to worry about now!

Looking good. I understand what Chaim is saying. Slid the clamp over the pins so that you can pull them through the holes, then pull back. Snip excess. Done.
 
Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

^ :) That's exactly what I meant Clutch ... I have no figure eight-holes in any of my graflex clamps yet,
so I can't test this theory . . . can it be done?

Looking good that real booster cone ... so I guess you have another complete (not cut) booster-bearing left to try my theory? Also how did you attach the booster cone to the top of the windvane neck? Nice real vintage balance pipe counterpart by the way as well as the grenade :) We'd like more pictures in this thread . . . please!

So what you're saying in essence is that the lower part of the pins (which currently lie against the booster) should be going under the clamp?

There is a booster cone inside the clamp already. The cotter pins are currently going through the holes in the booster bearing.

The balance pipe is the one that mates with the correct one. This is like the male version while the correct one is the female. It's from the correct engine.

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

Okay. Here's another attempt :

1. I did bend the copper-pin to resemble the pins that were attached into the booster-bearing in the second picture of the vintage booster gear below:

2. See how only one leg remains onto the cotter-pin which will make it easier if you want to follow the rest of my written tutorial. So cut one leg from the cotter pin for easy access through the first hole of the 8 lateron.
3. Position the cotterpin inside the booster-bearing like so (disregard the booster gear in the following picture for now):

4. Now slide the graflex clamp over the booster-bearing with the screwing part (= 'cone') of the booster-bearing outwards to the soon to be attached booster gear . . . so it can screw on lateron.
5. When you tilt the booster-bearing 45 degrees inside the clamp you'd be able to make it stuck behind those rectangular ridges inside after you straighten the bearing once again, savey sofar?
6. Now thread the copper-pin's leg, via bending it slightly, through the first hole of the 8 (farthest from the clamp edge).
7. Screw the booster gear onto the booster-bearing until it is blocked by the edge of the graflex clamp.
8. Then pull the cotterpin thight towards that same clamp edge so that it gets stuck in the second hole.
9. All that is left now is the clipping of the threaded cotterpin's leg to resemble the mechanismo/chronicles books picture:

Either I'm doing something wrong or step 6 is a physical impossibility!

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

Hi Marcus,

I think I see what you mean, hm . . . perhaps the cotter-pin needs to be say cut in half to be able to thread through the first 8 hole? And perhaps the booster-bearing needs to go deeper inside the graflex clamp so that the end of the cotter-pin comes exactly opposite the first 8 hole and then can be bend and threaded through it more easily? Would that work?

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

I have no idea how to accomplish this. I have spent the last hour trying and I have to give up now before the saber goes through a window! :lol

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

Phew, finally it is done. It was absolutely impossible to get both cotter pins in the configuration mentioned above. Once the first one was in it simply is not possible to get the second one in that way.

So the second one forms more an S shape. i.e. it is twisted to ****, looks a complete mess on the inside but looks okay on the outside which is the main thing. They don't really do a good job of holding the clamp and gear together though (it wobbles a lot), but James Kenobi 1138 put a threaded rod (actually two threaded rods) through the saber so it's nice and solid anyway!

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

So am I correct to assume you left both legs on one cotter-pin with one going through the eighthole? Even- though I did suggest to cut one leg of! And is your booster-bearing stuck nicely against the inside graflex tabs now? Awaiting patiently for your pics to allow us to hail your cotter-pin configuration :)

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

No, one leg was cut from the cotter pins with just a small loop on the rear side - this is not possible to do on both pins.

Not sure if the bearing is against the tabs. There is a metal spacer in there that the transistors and threaded rods screw into.

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

Ah . . . that explains your difficulties since my tutorial was intended for a clamp without a spacer inside, still I'm glad you seem to manage it ... now where are those pics, pretty please?

Re: Obi ANH saber. Where to place the cotter pins and 'figure 8' holes?

I didn't have the spacer in while I was wrestling with those blasted cotter pins!

This was used toput the emitter on grenade section?
I didn't know about that,it's interesting.
