Older style vertical feednecks - how do they work?

[Savet]

I've been out of the sport for almost two decades and there is an entire class of feednecks that seem to have come and gone and I can't find any information about how they work. Here's an example picture:



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?

You just cram it in there. Usually there is some sanding involved to make the hopper smaller. Sometimes tape to make it bigger.

Yeah no real magic you just had to jam in the hopper and hope for the best.

[Savet]

Wow...that seems horrible. Thanks!

"work" isn't a good term here. This was the era of watching a hopper bounce across the field about once a day.

Hopper neck too fat, sand it. Too thin, electrical tape.

Or in the case of that STO you unscrew it and replace it with a clamping feedneck.

Drilling, tapping, and putting in a small screw was also common.

It's really not that bad. They work just fine especially with the older flex shell type Revvy's. That softer shell would really kind of smush down and get in there nice. My STO with electrical taped revvy vs meteor with an inception feedneck they both hold about the same. The loader is just harder to remove from the old style feedneck if you swap between guns.

My old Apache had thick O-rings on it.
Cram it in, it got pretty snug.

You make the hopper fit. A halo or a rotor or modern force feed is gunna need a lot of sanding to fit one of those but a vl200 will jam in perfect.

so they took more tuning but they worked just as well, once setup.

I set my adjustable feedneck for the hopper
im gunna use and never move the adjustment again, just jam hopper in and out.

you don’t want it too tight to move with force because that just means either the hopper will break or worse your feedneck.

CP and DYE made hopper collets for Revys.

I always found an old piece of wrist band material qs a shim works super well for feednecks that are too small.

Electrical tape seems to be too thick in most cases. That wrist band material is waxy paper so it keeps shape and slides down into the bore with the hopper.

There's usually one blowing around at fields.

If we're thinking the same thing, that's exactly what I used. self-adhering bandage wrap; e.g. Coban. Definitely worked better than other tapes if you had room to get it in there.

twist ties would wedge in fairly well and many paint brands came with them.

I used to cut c shape notches out of the side of hopper necks with a dremel tool and install the thinnest o-rings I could find around the neck. The notches provided space for the orings to mush themselves into the neck yet provide enough give for the hopper to go into the neck. Do it at the tip of the hopper neck closest to the opening so if it does snap off you still have enough neck material.
