BT Vertical Adapter/Original Vertical Adapter

[trashcollector]

I need to add a vertical chamber to this 98C. I have the original one-piece vertical adapter as well as two of the BT 3-piece vertical adapters.

How? I know the 98C LPK kits are nearly unobtanium but where can I find the vertical adapter to add the vertical chamber or a t-fitting to work with the BT 3-piece? Are these so hard to find? Or make? How else did you solve this problem?
Damn these valves and these 90° turns

WTB LPK vertical adapter or entire LPK, I guess

I never owned a Tippman or messed with an LPK so I apologize if this doesn’t help but what if you bought a brass vert adapter and did some sweating for an inline brass 3 way fitting??

That was an idea but my searches weren’t coming up fruitful. I was hoping someone had a piece found or at least something close enough. I’ll keep on the hunt.

I assume you're trying to get more gas volume to the valve? I too mused on this problem before but came up empty handed. What I ended up doing was putting a big honking gas-thru grip through a BT vert adapter. IDK if it did anything but it sure holds more air.

Another idea I had was to cut out the body and screw a mini cocker vasa straight into the valve then run a gas-thru into that. I didn't want to cut up the body so I didn't try it but that seems like the better way if you want volume.

I think it’s more directional than volume. I instantly lost 30fps when I installed the adapter. Although it has a larger ID compared to the braided line, I think the 90° turn before entering the valve is causing my problem.
I think a large volume gas-thru would help but that’s where I want my Stabilizer.
I like that mini cocker vasa idea. I didn’t know those existed. I’m not sure I want to cut on the body yet.

280fps (braided) with a soft green spring to the dreaded 250fps (vert adapt) with all spring strengths.

Certainly sounds like it's restricting things. Thinking back, I may have drilled out the air passage in my vasa a bit to get it flowing better. I'll check when I get home today.

[RhoXi]

Yep, I definitely drilled it out. Looks to be about 11/64ths. Might be worth a shot before trying to track down a LPK.

Thanks for checking. Something to add to the list.

I made my own lpk using the newer BT 3 piece. I got a 1/8 npt street tee and reamed out the hole to 3/8 amd lubed the shit out of the oring. After that I added a techt low pressure valve spring and shaved the valve down for lots of flow. Some kind of volumechamber is good to have. I used a gutted, drilled, and pluged WGP lpr

To actually assemble everything there will be some shaving of the tee fitting and the cases. Beyond that it just works.

Awesome. Thanks

If you need more detail I am more than happy to answer direct questions

The best way is to run a steel braided line externally and ditch the BT tube and the BT valve adapter. Only keep the vertical adapter itself. So only 1 of the 3 pieces is used. Then use a male tank thread to female tank thread adapter. Drill and tap it for 1/8” npt. Or buy a gauge adapter if you can find one like the old custom products.

The BT adapter is secured in to the marker but it needs to be sealed well with JB weld. The male to female adapter threads in to the BT then you thread whatever you like in to it. I suggested a good reg but a gas thru grip could be used as well. No expansion chamber.

The M-F adapter is tapped for 1/8npt. Run a small steel braided over to another tapped M-F adapter that is running in to the valve. The best volumizer I’ve found (and I’ve experimented with a LOT) looks like this, from the top (going in to the valve) down.

Aeroflow 1/8npt thread extender
Shocktech mini cocker VASA
1/8npt tapped M-F adapter
MCSUS tuning chamber
MCSUS tuning chamber plug

No mining clearance needed. All plug and play. You could clear out inside the shells, below the valve, with a dremel to fit a street tee but it’s not really needed unless you want a touch more volume. The street tee would replace the Aeroflow fitting.
