Looking for scope help

    Re: Looking for scope help

    Scope clamp/mount:

    I'm sure this has been researched to death. Has anyone looked into "clic support hanger clamps" ? Or maybe a variation of this type of tension hanger? They have the built in spacer which I found interesting. They are used in electrical, plumbing applications.

    Yeah, I've looked at a bunch of those kind to DS72, but I don't think that's it. The piece as far as I can tell is a compression-style "clamp" that's squeezed to open. You can sort if tell this by noticing the "tabs" on the bottom are farther apart in the one closer to the flashtube, since the diameter of the gun barrel is wider closer to the breach. Still scouring, nothing yet...

    Re: Looking for scope help

    Anyone have any new leads on this? I just started looking into this part today and this thread seems a really promising start.

    I've sent off a few questions to some UK electrical engineers. Is this the last enduring mystery part of the ESB blaster?

    Re: Looking for scope help

    More thoughts, I can't sleep for thinking about this part now

    Could be an exhaust pipe hanger clamp?

    Looking at Art's picture in post #5 it looks like there is a gap in the bottom of the ring at least on the front clamp on the flash tube.

    I've been thinking the trapezoid shape is part of the clamp.

    Re: Looking for scope help

    So far Shabad, I've looked at tons and tons of automotive clamps, pipe hangers, conduit clamps, plumbing clamps and photography equipment. I've yet to discover something close This part is obscure!

    Re: Looking for scope help

    Ive seen that pinch clamp before. And im trying to remember where.

    It seems like they were in the engine of my dads old car. A triumph TR7

    On rubber hoses. We had to pinch them off to get to the spark plugs one time. I was only 12.

    Isnt a triumph a british car? Im not saying that for sure that those would be totally acurate, but ive seen those on the inside of engines back in the late 70s early 80s working with my dad. Well he worked. i was playing space ninja AKA Jedi.

    Thats where im starting

    Re: Looking for scope help

    This is similar to the ones in my dads car, except the ones in his car look more like the pictures, and were a black spring steel.


    I remember because my hands were small, so he asked me to get it off. like this

    This one is closer

    Volvo


    This band clamp comes big enough for the barrell I _think_. 48mm


    I realize that these have two pinchers on one side, but im not convinced the original didnt either.

    As for the caps, they look like bicycle or other nozzle caps. Which would be plastic and screw on to just about anything.

    Re: Looking for scope help

    Those look good stormrider! Great searching, I've seen so many clamps this week

    I'm not sure if it's the right part (I still think it might be all one piece) but it definitely deserves to be followed up. I contacted that supplier and they only have the clamps with a max expanded diameter of 42.42mm in stock, the larger 45mm ones are obsolete. They have a minimum order of 1900 but would work with a minimum of 500. I didn't get into cost.

    They offered to send me samples. I'll do that and we can see what they look like.

    Re: Looking for scope help

    Those are all the same kinds of clamps I've been seeing Storm! The "two pincher" one at the bottom is the closest, but.... I'm fairly convinced that the whole mount (apart from the molex bits) are one piece, not a clamp and "riser" as some have made. We'll find it eventually

    Re: Looking for scope help

    This is what I believe the mount to look like. I think that the one used is this, with a plastic standoff attached.

    Im not sure if they are truely one piece, or a plastic housing on a metal clamp, which is what I personally think, but i dont thinkt hey were fabricated to be part of it. i think its somethign used as a hose riser, to keep electrical lines off heated lines.

    Heres the clamp as I see it. Correct me if im wrong.

    Re: Looking for scope help

    I'm still sold on the idea that the whole she-bang is a solid piece, at least up until the flat piece on the very top that folds over the front and back. Initially, I thought the "nibs" on the squeeze tabs were round too, but I'm more inclined to believe they're flat either rubber or plastic "caps" on them tabs.

    Re: Looking for scope help

    I dont think its a solid piece. heres why:
    1. Time/era. Making it (The clamp) out of plastic wont work, its got to be spring to be a compression clamp. That means machined. Not cast. You cant cast spring steel, at least not that I know of.
    2. Weight. The weight of the thing would quadruple if the riser was steel. Again, weight = money.
    3. Energy transfer. Why make a 1 piece mount? What are you raising away? Your either raising another tubing, or holding the tube away from something, usually for heat reasons. Solid metal would transfer, vibrate, etc. This is the weakest of the four arguments.
    4. Mount being solid would stop the spring from flexing at all in almost 50% of the area, causing it to be a lot weaker, because allof the stress would be on the arms, where they thin out in order to overlap/wrap and be sprung. Again, not a good design. The ribs on the mount are to stabilize lateral movement, as well as horizontal. Otherwise it would be a solid piece. Because its 'ribbed' means they were keeping weight, and materials down while adding stability. The 'addition' of stability would difinitively stop it from flexing and defeat the purpose of a 360 spring clamp.

    I would bet its a spring steel clamp, with holes in it, and the riser has tabs that fit into each hole. Its not glued, or it wouldnt flex properly. Now, i dont think that they scratch built it. I think its a piece, thats two parts, but probably doesnt come apart without breaking it.

    *hammer*

    Rebuttle?

    Re: Looking for scope help

    Those are good points. I know absolutely nothing about manufacturing, so I can;t really give you proper feedback on those theories... It's really difficult to see, but look at how the from "face" of the piece continues unbroken from the trapezoidal shape straight into the clamp section. That's the main reason that I still believe at least that part is a one-piece construction. the squarish shape that's between the "body" and the top "strap" part may or may not be part of that, but there's no way for me to know.

    Re: Looking for scope help

    Heres an avi on how I think it goes together. Or at least close (some of the shapes could be off, but id place money that this is really close to the mechanics of it).

    The silver would be black metal, but I wanted to illustrate the two pieces.

    Hopefully someday the person that says they 'know what it is and have one' will shed some light on it

    Re: Looking for scope help

    Could be, it is hard to see a line separating the two shapes in the pictures we've seen so far.

    I got the clamp samples from EFC, they are too small for the webley barrel and the groove for the center tab makes up almost the entire clamp circumference when held at full open, that isn't seen in the pictures.

    Re: Looking for scope help

    Painted all black you wouldnt see the seperation at all. Because it would have to be really pricise to give stability. Any gap would compromise it exponentially.

    I have yet to see the proper clamp, but im going to measure my webley tonight, and order some samples from a site I found online. Its got two tabs on one side and one on the other, so its not the same as this one, but it will be close.

    Im building my own clamps and riser atm. ill post what i end up with.

    Re: Looking for scope help

    That AVI is cool Storm! One thing though is on that model the trapezoidal section looks too tall. If that's just for illustrative purposes ignore this

    So 42.42 wont go around the barrell?

    Re: Looking for scope help

    Heres my 20 minute PVC clamp.


    The distance in the bracket greatly depends on the size of tube and bracket. Because this is stretched a lot, it shows a lot of indention.

    If it were bigger, it would show very little. But notice the top picture you dont see any indention? Well its there. which I think is what you see on the esb photo, somewhat.


    This thing was made in 20 mins with a dremel. Its probably close to what ill go with.

    Re: Looking for scope help

    Look at the pic Art posted in post#5 The front clamp sits on the flash tube and it doesn't look like there is anything between the ends of the "clamp" such as the indentation of a spring clamp. That said it's a great looking quick mock up!

    The 42.42mm is the maximum opening of the clamp and pulling it that far open distorts the clamp out of being a proper circle making it impossible to fit around the end of the webley, add to that it would need to sit at the thickest part of barrel, beyond the limits of the clamp, it wasn't going to work. I can get it around the flash tube and take a picture if it would help illustrate what I mean.

    Another problem with the spring clamp is at full open sprung the clamp is almost entirely either a thin strip on one side or a dual strip of steel on the other. Its hard to see any evidence of that in the pictures we've seen.
