Belated Merry Christmas! ☺️

Right, so my brother works at a place which used to be the UKs biggest rapid prototyping / industrial scale 3d printing labs...  technically not anymore as they have been taken over by Siemens, so I guess their German now 😅.
They can print with powders of pretty much any material you want, both metals and polymers. Big massive rapid prototypers half the size of rooms. So yeah anything I suggest to him, he throws some elitist shade at . 

Yeah you're probably right, it is quite a 'load bearing' part, especially at the point at which the clutch essentially disengages when the magazine is full. Having said that, in this design you probably want these replaceable weak points to be able to break, so that you can easily and functionally replace them when need be.

Been thinking about purchasing a 3d printer actually, not really looked into it in much detail or know where to start and at what kinda price point. 

Yeah maybe, though I've heard some of the tougher nylon materials you can use to 3d print are seriously strong - not really sure what people are commonly using in their printers.

You gonna go for the OG odin parts kit or one of the 3d printed pieces - this place makes them, not tried them though, mine still aint broke 😜  https://isashop.eu/ 

I only ever order from the US when they are the only country who has something... usually takes a month or so for stuff to arrive and I seem to always get hit by customs with them.

I mean it's a necessary "investment" right 😜

Enjoy bud - How many primaries are you taking? I would probs pack the glock and some gas just in case; love me a backup to my backup to my backup 😅

Hehe, trust you to go for what is essentially the bullpup version of an SVD 😜

Happy Bday dude - nice PSO style scope, is that for an AK or have you joined the SVD master race?

Some East-block loadouts look pretty awesome..  might have a little browse of their shop

Did you try throwing new tappet springs in them, that's a solution that has come to my rescue with feeding issues on several occasions.

Either way looking forward to seeing them pop up on his channel 😜

 

Just sat down with a cuppa to watch the finale of clone wars, specially released a few days early for May 4th 

I'm feeling it too...  and I don't even have any of my guns with me to work on or tinker with. Apparently the new Thor movie 'Extraction' on Netflix is quite good, might give that a watch.

It sounds like a toddler getting a face tattoo...    🤣

Oh.. plugging my wifi dongle into a different USB port seems to have solved that 😅🤣

Yeah, I'd settle for a resurgence in the rat population in the garden to feed my 850 air magnum at this point. 

Eugh.. that sucks dude. The new RM rules are that anything bigger than a letter box hole will be left on the front door step... great announcement; the scumbags will be out in droves, probably tailing the RM vans!

M16 with a heat shield and m203 is my probably my favorite looking piece of all time, but sometimes i don't even take the moscarts with me, it just looks sweet is all. And goes without saying that it can make your load-out a little front heavy.  

@Cr0-Magnonoh yeah, that's another one - make sure the nub is engaged properly with the hop unit arm, if it doesn't lodge into the arm it may be displaced to the front or rear of the arm most likely resulting in a zero hop scenario. 

Some people like to super glue the nub onto the arm, which is fine for a standard nub, though not necessarily for a flat nub otherwise you may get a sloped hop surface - the tiniest blob of silicon gel can help keep it in place for installation. 

Yeah I certainly, even today think the prequels are just fine.. i'm mean flawed fine... but still fine, and significantly enhanced by the clone wars content imo.

 

Jedi and Empire are still my favs though. The new trilogy.. atrocious, heinous crime against star wars.

 

Yes, I was discussing that with my brother the other day; we were wondering if Alec Guinness' family were still getting star wars royalties off his deal. 

The Kamino landing pad fight is still legendary mate...

 

Yeah for sure there are quite a few things that could potentially go wrong with reassembly.

 

- ensure the hop rubber (the sleeve) is fitted correctly, with the protruding line seated in the long groove in the barrel and the protruding nub on the opposite side seated inside the little window in the barrel.

 

- It is possible to push the barrel with the rubber installed both too far into the hop unit thereby smushing up the feed lips and distorting them or equally not pushing the barrel and feed lips in far enough, either scenario will almost certainly run you into feeding problems. 

(sometimes with a very tight setup a small amount of silicon oil can help - just don't get it any where near the hop window)

 

- ensure the plastic barrel clip is engaged properly, with the two recesses fitting correctly into the grooves on the barrel - some times these can go on and you'll think its in place, but in fact the two recesses are just resting on the edge of the groove - this can cause the barrel itself to move, thereby moving the cut out window away from the hop up arm rendering the mechanism useless.

 

- custom hop nubs (especially flat nubs) can be too wide for your existing hop window and will require an equal amount of light sanding on each side until it comfortably fits into the window - the test is to press the nub down and see if it springs back up under the elastic force of the rubber without getting lodged. 

This could cause you an inability to push the nub down or it could cause the nub to become stuck, so that when you raise the hop arm the nub remains in its position in the hop window.

 

- Also do check the condition of all the hop mechanism dials and arms, It's not that common but some times these little pieces can become a bit minced.

 

Defintley, take the barrel and hop out, dissemble, then  reassemble checking at every stage.. to be safe, do clean the rubber on the inside of the window. You can see if the mechanism is working in its most basic form by looking down the barrel and adjusting the wheel while observing the nub lowering and rising.

 

Hope this helps dude!

Without taking the hop unit and barrel out of the gun, a diagnosis and fix is going to be difficult.

 

One non mechanical cause for ineffective hop is the contamination of lubricants such as silicon oil, which can be introduced by BBs coming out of a mag which has just been blasted with silicon spray.

Silcon spraying a mid/low cap can assist with a seized mag, but can also really muck things up for the hop if too much is used and transference onto the BBs occurs.

Mmm that 320 is more or less as it should be as far as i'm aware, the VN was a home build including the GB and I always try and do at least a half decent job on the air seals.

 

Anyway, So I took 6 coils off and crimped the end of the spring under a flame - got it down to around 365. Opened it up again swapped the bearing spring guide out for a very bog standard solid metal ACM one - and now it sits pretty much smack on 350 - DONE! 😪    It feels like a very short spring now though, it pretty much just sits in the gearbox flush without having to be pushed into the shell; made reassembly easier than usual!
