Locking Drop Tube Question

Hi All,
I was just wondering if anyone else is have "issues" with the locking type drop tube. The kind that has a collar that you tighten down around your hopper's neck by twisting the outer collar by hand.
I got one as an upgrade for my GZ (it fits on STO's also), but it never worked for my old hoppers. I guess they're tapered so when I try to lock the collar down, it just pushed the hoppers out of the drop tube, so I took the collar off and went back to my old drop tube...until HB and I cracked my hopper. I got a replacement from the VL table (cool guys, they treated me right) and the neck on my new shell was too fat to fit in my old drop tube..."cool" I thought as I broke out my chromed locking drop tube that I haven't been able to use. I popped that one on, and forced my new hopper neck into the drop tube...the darn thing is still too fat and there's no room to tighten the locking collar. I get it about a quarter turn down and it's not going any further. It holds my hopper in great, but the hopper sticks up higher in the air, and the slits in the feed tube are exposed for sand/dirt/water/paint to get into 'cause the collar doesn't come down far enough to cover them. I don't want to mess with sanding the neck, 'cause I don't want to take a chance on the hopper slipping out when I try to lock it down, like my old hoppers did. I can't even get the hopper off the drop tube now, I just unscrew the drop tube from the gun, put the old one back on to protect the threads, and pack the hopper away with the drop tube stuck to it.
I'm debating whether to keep it high in the air like it currently is, trying to trim the prongs on the drop tube (shortening the drop tube by cutting off a portion of the top)(it's nickle plated so that might ruin the plating, letting it flake off all over) so I can get the hopper lower and cover the slits ups, or just deciding to put a hose clamp on the thing (assuming i can get the hopper off of it to remove the locking collar) until I can get a Chipley locking drop tube. I also am debating about going ghetto and finding a locking ring for a scope and using that to lock down the feed tube neck onto the hopper neck.
Also, I got a black locking drop tube, but it actually doesn't fit onto the threading on my gun body. I thought Worr Games were the only ones that had an easily removeable threaded drop tube? The black locking drop tube is too small in diameter.
Hey, if anyone has any useful suggestions I'd appreciate it.

Thank You,
Ray

Find a new feed neck that fits or sand it down... The sanding part is actually recommended if you buy a Halo!!

If it's the GZ locking feed collar then yeah, they are tapered, but on mine I've not had a problem with it pushing the hopper out.

I'd suggest getting the feed tube off your hopper (brute force will do it, I've stuck one before too). Then the "prong" bit, put a bit of blue locktitie on it before screwing it down onto the stub out of the body, screw it down tight. Then the locking collar, slip that onto the feed neck before you put the hopper on i.e. it's completely off the prongs, The hopper should then slide in all the way and then just tighten down the collar. If it wont slide in the prongs you could bend them out a touch first.

One thing, on mine, as it's tapered, I just put one layer of electrical tape around the neck before it goes in. That way the prongs bite into the tape and keep it really snug and it doesn't rip up the feed necks of my hoppers.

Pinky: Thanks. I actually want to avoid sanding if I can. I'd like the neck to be nice and strong so it'll last as long as possible.

Beaker: Thanks. Been there, done that. Read the part about me being able to turn the collar only a quarter turn before it gets so tight that it won't come off again. I was happy the blue loc-tite broke before the fixed part of the feed tube did. The guys at the Angel Tech table in the players area said they frequently stripped the fixed part out of the gun when trying to remove stuck hoppers. I'd rather not do that...let's just say that it's well and truely stuck right now and if I ever get that locking collar undone, as I unscrew it, the locking collar top will be pushing against the bottom of the "eye" area.

Sad...

Hmm... Seems you got a problem then - Something is going to be modified unless you want to buy a loader that fits the feed neck or a feed neck that fits your loader!! :(

Best of luck!! (And I would still go for the sandpaper unless you can get proper feed necks without selling your firstborn or something - unless you have an EVOII I wouldn't worry too much...)

Pinky :p

Thanks...it's only been about a month since I last snapped a feedneck and that wasn't the last reason I broke my last shell...understandably, I have a nice strong feedneck now and am reluctant to weaken it (as I search for my sandpaper weeping). I've heard of people cracking their feednecks 'cause they cranked down on their locking collar and I've seen a few people messing with their locking collar. The Chipley version needs a hex wrench to adjust and I like to be able to remove my hopper on the field if needed (yes I occasionally do need to). Hmmm...maybe I'll trim the "prongs" and ask a friend if he can machine a locking lever system for me...I guess the cam portion should be adjustable with a hex wrench so I can get the locking force in the right range, and then use the lever to actually lock the feedneck in place like you would an air hose to fill up your bike or car tire...I'd position the lever to the rear of the drop tube...just thinking out loud...

Out of interest, have you compared the 2 halves of your locking feed to anyone elses that "works"

It's just that might tell you what is at fault (say the prongs too long) and then how you might fix it.

I can fit an unsanded HALO in mine and still have to crank it down a fair bit so seems like yours has to be different somehow.

I'll try this weekend. I have another locking feed but it doesn't fit my gun...I thought WGP was the only one that made that type of feedneck. That's what happens when someone goes "Here Ray, try this".

That's the one I got and it works perfectly.

Actually, the one that's stuck on my hopper is a chrome version of the one in your picture that I got from one of Bob Long's guys when I upgraded my GZ to a chromed Clamshell and the newer WAS board. The other one that doesn't fit my gun is from another manufacturer (well, another of Bob's guys works there designing the stuff) and I got tossed it in HB, and I haven't touched bases with him about it yet so I don't know if it's a protype or a production model or what but I think it looks kinda like some that I've seen on the all black Ironmen guns that everyone seems to like now.
