This is true, as long as there are just weakly acting forces. The contact is a frictional connection only, with a very low coefficient (plastic surfaces) in addition.
I meant detaching. The round openings all of our various designs enclose the cylindrical pins in a way which enables a...
I think the last prism mounted version will be much less sturdy regarding rotation than the 4-pin-snap-on version. These kink points of 45° won't deliver much resistance and furthermore just very few force against snapping off by accident.
I'm thinking about quite another version now...
To shape the snap on bracket more sturdy, you could place a kind of elastic hinge, like in my draft below. This would lower the risk of material fracture when bending. The thickness of the hinge could be lower than the rest of the collar (unlike my sketch shows).
Placing the base mount by forcing down the threadened eyepiece ring only doesn’t seem to be the best solution, as my experience with the aluminum collar shows. No matter how much you tighten the cover ring (by your finger‘s force), the collar can be turned by accident anyway.
If the base...
A snap on mount sounds cool. Maybe the snap on part shouldn‘t be snapped on the scope‘s thread directly, due to some reasons. First, much force would be necessary not to loose it by accident and second: there would be no way to snap it right without further steps of alignment.
How about an...
That really looks great, how sturdy are these nylon printed parts? I got no experience in 3D-printing and it's about time, I guess.
And yes, I do that metal stuff by myself, using my 3-axis CNC mill and a small conventional turning lathe. My workshop still lacks a 3D printer so far...
did You think about a turnable mounting plate? Should be easy by printing a collar with a socket at it's side (with just a hole in it) and a 360° turnable plate, locked by a screw.
As it's made from plastic (PLA, ABS?), the screw will cut it's thread by itself.
Sounds clever to meet these special needs! The angle of the mount seems to be fixed?
I'm going to check my CAD-drawings and let u know..
The thickness of the inner collar is 1.5mm, the outer height is 3mm (oops.. maybe it's just 2.5mm, have to check that) around. The front part of the...
That's the point. I can either remove the red dot sight itself or detach it with the aluminum holder, just leaving the collar mounted on the scope. The alignment keeps mostly fine.
The intermediate piece is just for additional height adjustments in case I'll need it. I was afraid the...
Red-dot mounting collar for Kowa 883
Here are some more detailed photos of the red-dot sight mounting. All parts were made from a plate of aluminum alloy (AlMg4,5Mn), thickness 10mm. Planned with CAD, machined with a CNC-mill.
The sight itself can be mounted and detached, all I need is a 3mm...
right, the threaded ring cover is used as a nut to hold down the aluminum collar. The inner diameter of the mounting collar is just 2/10mm larger than the scopes accessory thread. To mount it, you have to detach the eyepeace and cover ring, place the collar, screw down the ring and attach...
green dot sight mounted on Kowa 883
inspired by the different solutions of mounting a red/green dot sight to a spotting scope, I started thinking of a sturdy and adjustable mount for my Kowa w/ stay-on case.
So I bought the recommended (and affordable) sight (thanks Hauksen!) and...
