Serafino Booster Missing Part

(unless there is a hole on the top which isn't visible, or if a hole were drilled into it and then maybe tapped for the threaded rod).

There is a hole in the bearing where the bullets come out. A rod would fit through it. It's a great piece. It makes the clamp fit on very nicely.

If I were to put a saber together from all original parts, I would have used a threaded rod from the booster up to the balance pipe. I would have hammered in a dowel into the balance pipe and drilled a hole in the dowel for the rod and then cap it off with a nut. It would have held together really tight. I wonder why the original builders didn't do that.

It's the simplest way I could think of.

How stupid of me, theres a picture of the hole on post #32, hehe. We'd still need a spacer between the bearing and the grenade, correct? And since the clamp seems to fit snugly over the bearing and the grenade, the spacer would have to be nothing more than a simple tube with an ID of over .91 (to fit around the hex nut).
 
The bearing on my booster was way short of fitting into the clamp, hence me discounting it as being used on the prop.
Of course, that's not to say that it wasn't - but it would need something more than just the wire to perform any functional support inside the clamp.
 
What about holding the clamp to the booster via the tabs on the lower end of the clamp?
Was this possible with your booster Howard?

To me the more interesting theory is the bottom of the grenade sitting on the upper clamp tabs while being held in place with the 2 screws, and the booster baring resting on the upper side of the lower clamp tabs, thus allowing the booster proper to be screwed down onto the clamp.

The wires may or may not be the cotter pins from a booster, but it looks likely to me anyway.
 
Well I suppose that's possible. But you're talking about a very thin contact area when suggesting the bearing sits upon the clamp tabs.
I would have thought such a method would have been discounted by the original builder, due to its fragile nature - but as I said, it's possible.
 
To be clear, I'm thinking this was not exactly the construction method used for the prop during filming per say.

I do think the method I posted above, and the one James used was indeed the construction method by the time the Chronicles/Mechismo pics were taken.
Those pics are what I'm going for on my prop replica.

If you add some epoxy, it's as solid as a rock.

The bending down of the wires not only keeps the booster from unscrewing from the bearing, but it helps to 'hold tight' the clamp against the booster.
 
Well yes, if add epoxy to almost anything it's as solid as a rock.
If that was the case, then why didn't the prop builder run a blob of epoxy on the thread between the booster and bearing and then screw them together - no need for the wire then.

Things come loose. There is was what looks like epoxy on the grenade/balance pipe area.

We don't see any epoxy dripping out on the booster area though. That area would most likely have some if it was used.

A threaded rod would have been the easiest thing to use in my opinion. I don't see why they didn't use one. It's what I would have done.

So can someone make this part?
I'd much rather have a replica of something real, than a made up spacer no matter how sturdy and nice.
 
Why not draw up blueprints for it and hire someone like Russ to make one up for you then. You could even do a run, as I have seen enough posts like your calling for something like this.

If you read through the thread you'll see that blueprints are not a problem. :)

At this point the only issue is that we should wait for Russ' boosters to be complete so that when these are made test pieces can be at hand to make sure the bearing fits both Russ' and my boosters.

Reviving this thread as I had a question about the missing "screw" piece attachment.

I have one of Russ' clamp spacer adaptors - however to make it work, it looks like I would need to remove the screw piece. Do we have any updated opinions on whether the piece was on the original prop? I realize that the graflex clamp fits perfectly over the screw piece and in the end, once the saber is assembled, you can't tell whether the piece is there or not, so perhaps this is much ado about nothing....

Just wanted to hear some thoughts?
