I hope your attempt at printing a copy is coming along well :-)
Here's a picture of my test print, along with the main parameters:
Your PM quota is exceeded, by the way ... I think you need to delete a couple of messages before anyone can...
Interestingly, Nikon just announced a reflex sight for mounting on a hotshoe that provides both the red and green illumination as well as different reticles:
I believe the older Olympus EE-1 didn't have any of these features, so the...
Thanks a lot for the high praise!
Looks like an oversight on my part ... to make it available (for free), I just uploaded it here:
Any improvement suggestions regarding this variant would be welcome, of course :-)
While I don't have a Swarovski scope myself, I just completed the design of a NATO rail adapter for the ATS 65:
This was quite a fun project, as it was a collaboration with a Swarovski user who took the measurements, printed the prototypes...
Ah, I see - seems that the manufacturer uses big metal rings to mount finder scopes and such, probably not the solution you'd choose if you're weight conscious!
I'm fighting my new 3D printer at the moment ... it's actually pretty good in most respects, but I already identified one...
That style of adapter actually was my starting point with the Kowa. It is rock-solid but has the disadvantage of being a bit bulky and, more importantly, impossible to use in with the stay-on case.
I believe I actually posted pictures of the Kowa adapter somewhere near the start of...
I actually printed this design now, and it came out quite nicely:
Here's the "overload" test ... the adapter actually is perfectly rigid and takes the load easily:
Adapter weight is 64 g (without screws and nuts).
The design is available for free here...
One could make the rails' outer edges slightly wedge-shapes, then slide a ring over them that would push the rails together and fix the clamp in place.
(Or simply use a re-usable cable tie for that, eliminating the screws.)
I'll admit that I'm not sure how to deal with overhangs...
I'm glad.you like it! With regard to adjustment range, you probably need to turn the adapter a little against the scope body. Clockwise rings down the dot, counterclockwise btings it up. It will move laterally a bit too, so you need to re-adjust the sight in both directions after...
As you're an OpenSCAD enthusiast too, here's a module you can use to quickly create the NATO rail part of the mounting:
I'm looking forward to see what your mount is going to look like! :-)
The ring that holds the adapter in place is the accessory thread cover. Normally, it's installed on the scope at delivery.
It's a very slim ring that looks like a part of the scope body, and I wasn't even aware it was a removable part until someone told me about it.
I finally got around to make some photographs of the "iron sight" I created for my camera:
While this is a nice small and light gadget, the photograph taken from behind the camera already shows a bit of the focusing problems I mentioned, with only one set of crosshairs being...
I've had most of my stuff printed by Shapeways, and have been a happy customer so far.
My experience is with the Dutch branch only, but I'd think that the US company offers the same quality of service :-)
The price Shapeways indicates to me, if I enter "USA" as a location, is $9.85...
Since I've tried out the adapter a bit and found that it seems to be quite practical, I've now uploaded it here to make it available to everyone who'd like to 3D print it for himself:
No comparison, really :-)
Reflex sights give a sight image focused at infinity that stays on target even when you move your eye relative to the sight.
With an iron sight, you have to bring your eye to a very precise position and keep it there, and you can only focus on either the sight...
Thanks! :-) The iron sights sort of invented themselves ... with the first prototype, I noticed I was sighting along the rail even before the actual sight was attached, and then found that the lightening hole near the top was even better for that purpose.
I thought I'd that sighting...
Thinking a bit more about it, it would be ideal if that collar had a hole drilled in its circumference to allow locking the sight adapter securely against twisting.
I just sent an email to my contact at Kowa asking for the availability of the TSN-PA7 collar, and included the...
Today, the printed part arrived. I haven't done a thorough test yet, but I'm happy with the looks and fit of the part.
It still is possible to twist it out of adjustment by force. Maybe I'll have to increase the gap width of the collar a bit to allow it to be tightened tighter...
You're welcome - the design really owes much to your input, too! :-)
The sight you linked basically the same sight Vollmeise and I have (which is available under dozens of different names). The version you linked will fit on my rail with no adapter just fine.
If you're interested, I'll provide the print file for free ... just upload it to shapeways.com (or your 3D print provider of choice) and have it printed. (Or print it at home, if you have a 3D printer :-)
It's too big for uploading it here ... 14 MB - I hope your inbox can take that...
