Discussions on cylinder locking mechanisms

[racprops]

A little excited?? Three posts...

I am using what I want to call the "Andy Lock " in honor of Andy thinking of the possibility that the large flat slotted screw might be used to pull in and lock the front of the cylinder.

I now think that is what was done on the Hero gun and I am now doing it on ours.

Both Eltee's and mine have this system, I bought screws with almost the correct head size and the machined then down to thread them with 4/40 thread.

So a big thanks to Andy (our Andy) for pointing that out it makes these shooters MUCH safer.

I am sharing these details freely so anyone trying to build one will know of this important safety system, I looked at the cylinder line up though the barrel with out this lock system and it could and did misaligned.

Excellent thought process Andy...and thank you Rich to have explained it in details: it make sense to me now why that screw is on the side plate now

It was Doc3D that first came up with the idea. I think I just noticed that the weaver knob lined up with the cylinder crane on the Hero gun and theorized it may have been used on the Hero before we got a chance to see the screw holes inside in the cylinder compartment also lining up, confirming it, and Doc's theory. Doc, for the record used Craig Kovach's method for holding the cylinder in the end for his shooter.

Craig keep the cone shaped locking part of the injection rod so it still locked the front end in place.

So did Doc explain it in the detail as you did, Andy??

You as I remember campaigned this idea, and I then tried drilling thought a bad casting of a stunt model first and the holes seemed to line up so I then used one of my metal castings to totally prove it.

Here is Doc's explanation of what he did and why, also showing a Craig Kovach firing gun cylinder detail ...

I am not sure if this was his first mention of using the Weaver scope knob (or other screw in that location) to secure the cylinder or not, but it does talk about it here. He and I may have discussed it between us too. I just knew when I heard the idea I was convinced it would work, and was very likely what they did for the film gun. As you said I lobbied for the idea. I was very excited when the pics of the inside of the Hero showed up and confirmed it. Not as elegant as Craig's solution, but it made sense when looking at the Worldcon pics. It also seemed to confirm that the Weaver knob was a later add on, and the slotted screw was more likely the one used throughout filming, since the Weaver knob was in no way long enough to secure that cylinder safely.

OK I see that although he said it once or twice he did not go into detail about it.

So I guess I will leave any name off it...

Or call it the Doc3D&Andy system.

Otherwise in a little while it will become known as the Coyle cylinder lock.

You call it.

PS How about a vote??

Since it was done on the Hero by the the guy(s) that made it originally, the name should be the 'original "Hero" Locking system'. The pieces I discovered on the gun like the Weaver scope knob and radio binding post are often called "Worldcon" pieces. I am okay with that.

Andy

[racprops]

I am OK with that then.

First they do seem to line up.

Second as even a blank has some wadding I think a proper alined barrel to cylinder is a good idea.

How are you so sure about this? We already had a demonstration of the need for this from doc3D and it showed even with blanks it was necessary. The flat head screw would slow down reloading more than a few seconds. Wouldn't make sense if it were a real gun in action though.

Andy

[andy]

The weaver knob was also not long enough to keep the cover on tight so it is just a bit loose. Once a proper screw is in there it would tighten right up. It is also missing another screw that should be in front of it.

My question is that you seem to live/work near LA, and say you are in the business. Have you actually had the hero in hand and know something we do not? From what I have deduced over looking at many pictures and cross checking them, is that they do line up. I see nothing to show otherwise, but have not held the gun in my hand and had the opportunity to double check it by taking it apart, or putting a screw through it.

Andy

[racprops]

Andy you need to address whom your talking with...

IF me I had to machine a screw down to 4/40 to make it work.

AND in a film production reloading slowly would not be a problem..

And this prop really make NO SENSE as a real gun.

I wasn't talking to you Rich, I was talking to Phoenixent, you were backing up what I am saying anyway. I think you posted as I was writing too. I didn't see it until afterword.

No problem: ships in the night...

Well I too worked in Hollywood and found that with a shooter they was plenty of down time for a reloading and that almost ever load was scene special, say a two shot for "scene one" then a new set up for the next take, which always takes longer that the reloading and again only the number of rounds that the scene calls for.

Take a normal action scene: Hero fires two to his front..he get two rounds.

Then they set up for him to turn and fire three to his right..he gets three rounds.

Then they set up for him to turn completely around and fire one to his rear, again only one round.

They do not like to load more rounds that needed to each set up and scene.
