Older style vertical feednecks - how do they work?

[Euphie]

I never had a problem tbh. The single best thing to do is a simple rule 1 hopper for 1 gun. With proper sanding things should fit really well, it is best to avoid having to add material which is why it is best if each hopper has it's own gun because if you have to further sand it down then you need o-rings, electrical tape, paper wedges, or a set screw to keep the hopper on there.

Also some feednecks that don't have external clamps really do have o-rings, feedgates, twist-locks, etc but, I not sure if any cockers did. I have a matrix with little twist lock inserts that have multiple sizes for example. Nowadays people who want to run new stuff on older guns will frequently cut down the feed neck to where just a little tube is left and use something like a Lapco universal clamping feed to get an Empire style feedneck or use a Spyder style vertical clamping elbow if they need the high rise for an agitating hopper

nowadays some owners of these guns are sending them off to places to have the stovepipe feedneck machined off and replaced with a clamping feedneck.

Also, a company named Trinity used to make an clamping feedneck specifically for these guns, that slipped right over the stovepipe, clamped down on the bottom, and gave you a lever clamping feedneck up top for the hopper.

You know you’re getting old when people are asking how a force-fit feedneck works. These replies make me feel old too.

Happened to my wife & I the other day. Someone was wondering how something from our childhood worked, even despite how simple it was. :facepalm:

had to explain what the "attachment" icon was the other day.

Imagine how old I feel, having completely missed this trend and fondly remembering my elbow adapters. I'm loving the new clamping feednecks though.

Savet I still use elbows. When my last VLbow breaks it will be a sad day.
I really like the Eclipse clamping feednecks. A fairly common mod for older VF cockers is to mill off the factory press-fit neck to a stump & put an Eclipse neck on.

How does this feedneck create tension on the hopper neck? I've seen some examples that look like they may screw down, others it looks like they may have some internal tensioning mechanism like o-rings. Can anybody share some information or a link that I can use to bring myself up to speed?

back in the day, everything was pretty standardized, all the hoppers available were the same diameter, and so it was pretty easy for the engineers to make friction fit feednecks.. usually you could just stick the hopper on it and it would get nice and secure by the time it was seated.

after brass eagle bought JT, they "fixed a mistake" by switched the mold from 1.1" (the mistake became the standard) to 1.0" suddenly a lot of hoppers were too small to fit, manufacturers had to adapt to the smaller size.. people just used electrical tape, paper, etc.. to use as a "shim"... and some of the first clamping feedneck started to show up. then the halo came out with an oversized 1.1 feedneck that you would need to "sand to fit"

that flew for a little while, but i think they under-estimated how much nobody wanted to sand a hopper feedneck.. so then the clamping feednecks really took off so you could use a multitude of hoppers without modding anything

Youngsters may not remember when CCM was almost mainly a clamping feedneck company.

I even remember when they had parts in stock
