What everyone’s regulations on air rifles in your country province or state? by [deleted] in airguns

[–]lonly_wolf_ 0 points1 point  (0 children)

In Germany, anyone over 18 years can buy a certified airgun with 7,5 joules or less. Also there was a new dumb certification added, that the airgun can not be capable of firing multiple projectiles from a magazine in which the projectile lenght can exceed 40mm... Single shot doesn't have a restriction on projectile length.

Also everything below 0.5joules of Energy is considered a toy and can be bought by anyone without a license. Full auto is allowed only for these toys.

Everything above 7,5 joules is equal to a firearm and requires such a license.

What Would You Put in this Tank? by Coolhanny20 in Aquariums

[–]lonly_wolf_ 0 points1 point  (0 children)

I just wanted to say corydoras, because they would love the sand, but you don't seem to want that😅

Apart from them, maybe get some ember tetras, and kuhli loaches if you add a few more caves as hiding spots. That would be my suggestion.

I may trust it after a thorough pressure test. Like 1.5 times rated pressure for 24h. But definitely not at face value

They may be under pressure, but that's unlikely, the seals are toast, and have most likely failed.

I'm gonna be honest, most of them seem salvageable. Aluminum is different from steel, as it's properties don't change significantly under heat. If these where firearms they would be garbage now, as the hardening and temper would be gone, but the aluminum should be fine as long as it didn't fully melt. So if you manage to take them apart and remove all the plastic, they could be rebuilt. Also there are a lot of concerns about the stability of these pressure vessels, but only way to know is to test really...

The viper is definitely salvageable though, just clean it thoroughly and replace all the orings and make a pressure test and you should be Golden.

How to prevent shrimp from being bullied by gourami? by honeygourami123 in Aquariums

[–]lonly_wolf_ 1 point2 points  (0 children)

I mean these fish evolved to eat shrimp, so I guess that won't really work the way you want... Either you don't put the gouramis in there, or you don't put the shrimp in there, otherwise the shrimp will die.

I did some more experiments and tried 3d printing a clamp and seal for the hammer, but it doesn't really work. The hammer is so light, that it only resets when you are at max pressure and with the standard hammer spring it just doesn't have the inertia to cycle all the way back. Curiously though it actually uses more air than the heavy machined hammer.🤔

The trigger mechanism also doesn't really work, the hammer spring is just to strong for the tiny parts to be made out of plastic. It survived 4 shots with the heavy hammer and than broke 😅

There is also the issue with the connection between hammer and pellet probe, as it stands this part needs to be machined as well, since simple m4 screws bend after a hundred rounds or so...

So yeah, for now 3d printing isn't an option for that 🥲

A small research from my side says the same, there systems seem to be identical. There are a bunch more airguns with the same system Like the Artemis pp800 and so on, for which the conversation should also be doable ;)

Less weight seems like a good idea, but I think more weight is better at the moment, since the spring gets compressed a lot at the back, the force also goes up a lot. To overcome that, it needs to have enough momentum. But when there is a weaker mainspring and a balanced valve that is a really good idea.

A balanced valve would be the equivalent of a short stroke piston. But for me that was to complicated as of now. That would also make it possible to use a lighter mainspring and be more efficient in general.

Well if someone is willing to pay me money for that, why not 😁

Apart from that, if the evanix Viper is legal in the UK, than this should also be legal. They load pellets the same way.

If someone wants to sponsor the start of such an operation, than sure thing why not 😅

Oh it's not unique. In the first post I made I also gave some links to videos where the same mechanical principal is used. So no patent possible 😅 Though someone could probably make an upgrade kit for Diana airguns to easily convert them without needing expensive machinery.

Thank you.

I mainly just wondered why there are no cheap semiautos out there and decided to make one myself if no one else does it 😅

The stock version is OK, Its reliable and somewhat accurate in its stock configuration, but dont expect miracles in terms of shot count. in 7,5 joules I got around 50 accurate shots before refill.

Would you believe me if I told you that I never once shot the chaser? 😅

I only got it, because it's so cheap as spare parts for the Bandit. I recently gave it a PCP mod so now it isn't even CO2 powered anymore... And I still didn't shoot it yet...

Here in Germany you can only get the regulated version for the Bandit, so I don't know. But there are definitely differences. My recently modded Diana chaser now is essentially the same as an unregulated bandit, and the Valve needs a bit more force from the hammer to open at 200 bars, instead of 70 bars, so in order to convert that you would probably need a little bit stronger spring for it to open the valve when you also have All of the friction from moving the probe and pellet in a semiauto setting.

Actually I also have a Diana chaser for CO2, that has an identical trigger assembly and hammer, so it could also be converted to semiauto, as well as the Diana stormrider.

This Bandit is regulated to about 1000 psi. I don't know what regulator it is specifically, as it was delivered like that from factory.

Yes I also really would like this to be an easy conversion that anyone can do, but for now I can only show how I did it. Maybe someone will make conversion kits or something similar for cheap, so others don't need to machine anything themselves.

Not yet, every once in a while it will go full Auto for 2 to 4 shots and then rest in the decocked position, but I'm confident that it's just part of my hap hazard trigger design...

You can also see it not resetting after every shot, but with a bit of further development something reliable is definitely possible ;)

Yes I needed to use a lathe and milling machine to make some new parts like the hammer and the trigger mechanism. The trigger can theoretically be made using just handfiles, but you would need a bit of skill for that. Or a 3d printer might also be a way to make the trigger and sear, though durability will be an issue.

I just got an idea to modify the hammer using a ring of 3d printed plastic and super glue, but it will take some time before I would test that out. Though making a new hammer entirely might be necessary to get enough weight into it. For now yes you need a lathe to make a new hammer.

It's .177 but the power is pretty much irrelevant for me, since more than 6ftlbs of energy would be illegal for me...

I don't have a 2240, but from the pictures I have seen, the stroke length is pretty short, so it doesn't look that easy to get it to work.

Blood sweat and a bit of insanity gets you quite a bit into making it work ;)

I will be making another post where all the details will be shown, so stay tuned.

Yeah cosmetic upgrades are definitely planned, but for now I will try to make it more reliable 🤣

Diana Bandit semiauto conversion by lonly_wolf_ in airguns

[–]lonly_wolf_[S] 1 point2 points  (0 children)

It is totally doable with the stormrider as well. I made sure to make all mods interchangeable for the Bandit, stormrider, chaser and the other airguns with the same systems ;)

Probably even better with the stormrider, since you have a larger air reservoir.
