    One Legged T-Rex (OLTR)

    Pre order page is up> http://www.lukescustoms.com/t-rex.html

    Oops, lost the other thread. (sarcasm)

    The overseer, a little tribute to TK.
    Found this little guy in the trunk of a car at an auto salvage yard. He was buried under a pile of old parts, dirt and trash, he's missing an arm, leg and both hands. I saw some irony in his discovery so I had to dig him out and bring him home. lol



    On to other news...

    I've been working on the T-Rex for 3-4 months. I believe I've dialed in the final design but several more phases of testing is still required.
    The design incorporates a built in mounting tab and an airline hole to pass a LP hose through if you're bringing in low pressure air from a forward mounted regulator.


    Here's the two latest working prototypes, V9 and 9.1 essentially they're the same but with minor machining changes (A few different internal chamfers to cut down on the number of tools and tool changes.)







    Did more bench testing yesterday after machining this little mount. So far this little dude rips, feeling stoked about the design. But more testing is required.







    The body and valve assembly are machined from brass.
    Trigger pin is non proprietary, made of stainless steel. The current design locates the trigger pin pretty close to a factory set trigger pin. These can be ground down without affecting the valve operation if you want the trigger to sit back further in the frame. The trigger pin is an off the shelf 1/8" x 3/4" dowel pin.
    The trigger pin has a built in stop in the valve body, it is impossible to over pull or bottom out the valve assembly.
    The pin stroke is set at 0.04" but I believe it will operate at a much shorter stroke. (Again further testing is required)
    This design uses orings in all the spots that need a seal, NO Teflon tape or thread sealer! Sounds silly but that's a big deal when you sit down to assemble a bunch of parts. Also, sealers can be problematic on pneumatic valve systems.



    For the record this is not a Zap design, parts are nowhere interchangeable, the valve assemblies are completely different.

    If you're interested in the project please post. Pricing will be within the scope of what's come before.

    This will not work in the following frames:
    Z-Grip
    Y-Grip
    RPG Triton
    Airwalk (Too close to call without CAD's)

      Thanks!

      What frame are you considering for your build?

        Would this design work for z-frame?

            I would be interested in two as well depending on price and how easy it will be to get this in intelli style frames

              For these to work properly it will require professional machining to the frame to work properly. There's almost no leeway on the cheater to do modifications to it. I'll looking to frame mods after the cheater is ready for production. Lots of testing is still required.

                I'm down for one still since I have all Luke lowers on my current build. If I have one of your frames I'm assuming I need to send it back to you to have it modified, is there a cost on that and if so how much is it or is it too early to crunch numbers?

                  I will take 2 when the time comes.

                    Still down for a couple of these.

                      To mount the cheater all that is required is a single hole to be drilled. (See picture #7 from the top) However, I plan on adding a magnetic trigger return and a hole in the rear of the frame to reset the on/off when required. I'll work out some kind of a deal for all the frames that have been sold, all new frame sales will come with those additions.

                      I'll take care of you guys one way or another, this cheater was the reason those frames didn't come ready for a typical pneumag build.

                        ill be in for two. one for one of your frames on a classic RT, and another for in one of cougars M86 frames. will need some rail milling on both projects as well.

                          So it would require a fair amount of work for a Y-Frame?

                            Cougar will have to verify if his frames be a candidate or not, I haven't really studied his frame that close so I'm not certain one way or another.

                            I won't be able to personally test that setup, has anyone built a pneumag on the Classic RT platform using a MSV2 and MPA-3 ram yet? If so it shouldn't be a problem but that's just a guess.

                              I'll take another mini vert and one of these.
